What Are The Characteristics Of ERP Systems Information Technology Essay

In Literature Reviews chapter, researcher discuss about the conceptual model of mention after critical analysis literature harmonizing to research aims.

ERP undertakings are typical in development, planning, execution, use and even in result. Standard soft-wares ( IT Projects ) is merely concern with individual map of an Administration with specific functional function, on the other manus ERP systems are consist of multi-functional functions and concern with all maps of the company. Hence basic criterion soft-wares are merely concern with the functional ( section ) position position of the company, but ERP systems are wholly focus on procedure ( co-operate ) position position of whole company. Writer argues that ERP Projects are alone from IT undertakings because of following factors:

2.1.1 Cross-Functional Integration:

Harmonizing to Davenport ( 1998 ) ERP systems provides “ seamless integrating of all the information fluxing through a company fiscal and accounting information, human resource information, supply concatenation information, and client information ” . Standard Projects are focus on functional implementing merely, but ERP systems are focus on integrating of all functional package to bring forth a Business procedure oriented package solution ( Markus and Tanis, 2000 ) . ERP system undertakings helps administration to pull off usage of resources ( sections or maps ) efficaciously and expeditiously, by incorporating all concern maps ( Nah et al. , 2001 ) . ERP systems have the capacity to incorporate information from several different maps or sections of an administration such as finance, fabrication, purchase, and human resources ( Amoako-Gyampah, 2004 ) .

2.1.2 High Cost & A ; Complexity:

ERP undertakings comparatively have high hazards than any other criterion & A ; conventional undertaking ( Luo and Strong, 2004 ) . As Chen ( 2001 ) study that ERP cost with package, hardware, consult, and employs merely done every bit high as 2 % to 3 % of company income. The cost scope for use a new ERP can be between $ 2 million to $ 4 million for a little house and as for a big house it can be over $ 1 billion, reported a combination of cost apply for its ERP system as: package, 16 % ; hardware, 32 % ; system integrating, 38 % ; and head count, 14 % .in the above dislocation cost of adviser is non tinted. At the be aftering face of the ERP undertaking execution, complexness of the execution caused high rates of failure in undertaking, which resulted in accomplishment of few benefits from expected 1s ( Sammon and Adam, 2005 ) . Percept of the hazard is large ground for rejection of ERP undertakings ( Aladwani, 2001 ) . High resource allotment, high outlook of concern benefits and hazard related with ERP undertakings, makes ERP system execution much more complex as comparison to any other criterion package solution undertaking ( Kumar et al, 2003 ) . Ii¬?nedo and Nahar ( 2009 ) “ ERP systems are dearly-won to get and their acceptance procedure is frequently fraught with hazards ” . Parr and Shanks ( 2000 ) stated that the figure of ERP project exceed from the planned continuance and budget that is estimated in the initial stage of the undertaking, with limited planned execution range. Although redesigning of concern procedure ( ERP systems ) bring about addition in net income, but it besides increase the degree of hazards, cost & A ; complication ( Somers and Nelson, 2003 )

2.1.3 Change Management and Reengineering:

Installing ERP systems does non intend that administrations are put ining a package system ; in fact it ‘s a measure towards alteration, a alteration in administration construction and civilization, and normally this alteration is against the bing administration civilization ( Davenport, 2000 ) . Change direction major concern with the effort to manage people or employee emotional ups and downs, when administration planning or set abouting a monolithic alteration measure in its construction. Administration required responsiveness actions towards there internal clients ( employees ) to hedge job related with factor of alteration ( Al-Mashari and Zairi, 2000 ) . Execution of ERP undertaking can do confrontation, opposition, uncertainness and mistakes ; because of alteration direction issues that frequently appear as ERP undertakings provide complete new work environment ( Al-Mashari and Zairi, 2000 ; Meyer, 2000 ) . Requirement of Business Process Re-engineering ( BPR ) is normally required in companies before implementing ERP undertaking ; hence ERP undertaking can aline with maps, procedures, characteristics and activities of the company. Process Engineering & A ; Flow redesign are ever conveying into drama, while using ERP systems as a procedure direction tool ( Davenport, 1998 ) . Transformation related with IT ever requires detail attack towards the sum of graduated table procedure and alterations related with ERP executions ( Markus and Benjamin, 1997 ) .

2.1.4 Stake-Holders Engagement:

Stake holder may exercise assorted sum of power with their specific ain involvements, that can be utilize to act upon or deviate the consequence of the procedure implemented ( Markus and Keil, 1994 ) . Numbers of stakeholders are involved during the execution of ERP undertakings such as, undertaking director, administration managers ( top direction ) , team leader and co-ordinators and terminal users ( Amoako-Gyampah, 2004 ) . Attempts for implementing engineering chiefly depend on the actions of administration ‘s direction, leaders, policy shapers, employees and in peculiar end-users who will be affected by engineering ( Lewis and Seibold, 1993 ) . ERP systems face execution troubles because of terminal users ( Aladwani, 2001 ) .

2.1.5 Training Requirements:

Employees must be decently trained harmonizing to demands of their occupations, while implementing alteration agent that can act upon organisation civilization ( Rosario, 2000 ) . Ignorance to developing plan, that causes deficiency of understanding for ERP system, consequence in failure of undertaking execution ( Markus and Tanis, 2000 ) . While implementing & A ; planing ERP systems users ( employees, clients, providers ) should be involved and for that peculiar ground preparation & A ; instruction should supply to users, so that users can execute it decently ( Holland et al. , 1999 ; Nah et al. , 2001 ; Bingi et al. , 1999 ; ) stated that employees need preparation and instruction to acknowledge how the ERP system will modify concern procedures. Extra preparation, mentoring and support for employees and director should be provided during execution

2.1.6 High Time Scale:

As reported by West and Daigle ( 2004 ) , “ accomplishing many of ERP ‘s benefit takes clip ” . Ahmed el at. , ( 2003 ) , study that harmonizing to conducted instance surveies, the least implementation period for ERP undertakings was starts from 1.5 old ages and up-to 5 old ages maximal. Frisk ( 2004 ) studies that one of the four major jobs in IT benefit direction is the clip factor related with apprehension of benefits of ERP execution. She reports that benefits are non stable with clip which makes hard to organize a complete list of possible benefits. There are many companies that prolong jobs, so do non take advantage after the completion of first twelvemonth of execution ( Tsung, 2004 ) .

2.2 Implementation Strategies for ERP system:

Implementation scheme means as a consistently order and prepared attack to implement any needed system in administration, which is depend on the construction of the administration, issues ( proficient, economical ) , handiness of clip and physical location of an administration ( Markus et al. , 2000 ) , the appropriate execution attack should be selected. Another of import issue is that the system meets the awaited outlooks ( Hong & A ; Kim, 2002 ) . It is besides of great importance to hold an execution scheme. The execution scheme should include technological facets every bit good as budgets, methodological analysiss, time-plans, ends, visions and managerial guidelines ( Al-Mashari et Al, 2003 ) . There are fundamentally 2 different schemes for implementing ERP system, the first scheme is a scheme in which administration has to reengineer the whole concern procedure and bequest system to ease the functionality of implementing ERP system. The 2nd scheme is focus on customisation of ERP package solution harmonizing to Organisation concern procedure and bequest systems ( Holland & A ; Light, 1999 ; Parr and Shanks, 2000 ) . Different writer ( Holland & A ; Light, 1999 ; Fu-Ho EL at. , 2004 ; Bingi et al. , 1999 ; Olson, 2004 ; Al-Mashari et al. , 2003 ; Parr and Shanks, 2000 ) specify different type of schemes and attacks for implementing ERP systems, which are listed as follows:

Best of Breed Strategy

Single Vendor Strategy

Skeleton Strategy

Single Module Strategy

Big Bang Strategy

Vanilla Scheme

2.2.1 Best of Breed Strategy:

Best-of-breed ( BoB ) is an attack to choose and implement the best faculties of a system in an endeavor ( Holland EL at, 2001 ) . BoB scheme aims to incorporate criterion or usage package bundles from assortment of sellers ( Holland EL at, 2001 ) . In position of Holland et Al ( 2001 ) the chief aim of BoB scheme is to plan system that is strongly and decently aligned with concern procedure of implementing administration. Harmonizing Olson ( 2004 ) it is rather normal and common that administration do non like to implement ERP systems wholly from a individual seller, because of high disbursal and plus administration do non necessitate all the faculties of the system. ( Olson, 2004 ; Holland et al. , 2001 ) argues that BoB is most idealistic scheme for ERP execution, which try to happen out the best faculties from the different sellers and implement them, by integrated them in a manner which is best for administration.

2.2.2 Skeleton Strategy:

( Fu-Ho EL at. , 2004 ; Bingi el at. , 1999 ; Holland el at. , 1999 ) define Skeleton scheme as an attack in which package bundle is being put in in version of skeleton ab initio or so called basic version. When the end-users of the package bundle are familiarized with the bundle, so excess functionality to the package are added. By skeleton attack, the roll-out of an ERP system across multiple sites can be achieved in a much shorter timeframe. That helps to continue the impulse of the undertaking and prevent employees ( end-user ) to coerce and retroflex there legacy systems onto ERP system platform.

2.2.3 Single Module Strategy:

( Holland el at. , 1999 ; Markus, 2004 ) explains that ERP systems are consist of many faculties, and an attack in which a individual ERP faculty system install at a clip while working with bequest system of administration known as Single faculty scheme. ( Holland el at. , 1999 ; Markus, 2004 ) argues that individual faculty attack can be implemented in bing system of an administration in analogue or it can be install of its ain every bit good. Mostly international undertakings are more complex because of large range, multiple undertakings and multiple squads are working in different parts, Holland EL at. ( 1999 ) argues that Single faculty scheme is rather suited from these types of undertakings.

2.2.4 Vanilla Scheme:

Vanilla scheme protects the originality of ERP package bundle by concentrating on minimal customization of bundle ( Holland et al. , 1999 ; Parr and Shanks, 2000 ) . Vanilla scheme is more or less focal point on reengineering of administration construction and manner of processing, supplying support of ERP bundle by cut downing mistakes and defects to it ( Parr and Shanks, 2000 ) .

2.2.5 Big Bang Strategy:

Harmonizing to ( Mabert et al. , 2003 ; Markus et al. , 2000 ; Markus, 2004 ) Big Bang scheme is the reengineering of whole administration procedure or bequest system or in general word closing of old bequest system. Harmonizing to Holland el at. , ( 1999 ) Big Bang scheme is a scheme that interfaces with the bequest system. The whole administration will halt utilizing old bequest system and starts to utilize new ERP system at a same clip. Big Bang scheme execution requires long clip planned execution, with specific adjusted ERP solution for administration.

2.2.6 Single Vendor Strategy:

( Holland el at. , 2001 ; Holland el at. , 1999 ; Parr el at. , 2000 ; Olson, 2004 ) defines individual seller scheme as an attack in which administration decide to choose one individual Vendor ( SAP, Oracle, Microsoft, etc ) for whole execution procedure of ERP undertakings. Holland EL at. , ( 2001 ) explains that individual seller attack supports to make high degree of proficient integrating and improves the coherence within administration ; high degree of reengineering is required for execution. Holland EL at. , ( 1999 ) “ to implement a system with complete functionality in a individual attempt ” describes “ Complete Functionality scheme ” for individual seller scheme.

2.3 ERP Project Life Cycle:

( Markus and Tanis, 2000 ; Bancroft et al. , 1998 ; Al-Mashari et al. , 2001 ; Parr and Shanks, 2000 ; Somers and Nelson, 2004 ) all of them proposed theoretical accounts for ERP execution, in order to acquire clear and deep apprehension of ERP execution procedure, supplying guidelines for successful ERP execution.

Bancroft et al. , ( 1998 ) represents ERP execution phases after analyzing ERP execution within three transnational companies and discoursing findings with 20 Practitioners. Bancroft et al. , ( 1998 ) execution theoretical account has 5 phases:

Focus stage: is fundamentally a planning stage in which cardinal activities are planned such as choice and structuring of undertaking squad, puting up of commission, creative activity of a undertaking program and development of the undertaking ‘s guiding rules.

As Is stage: is concern with analysis of bing concern procedure, installing and constellation of the ERP, plotting of the concern processes onto the ERP maps and undertaking squad preparation.

To be stage: is chiefly concern with end-user of the ERP system, sophisticated and full design of the system is been provided to end-user, which is supported by paradigm of existent sort and by regular coordination and communicating with end-user.

Construction and Testing stage: is chiefly focal point on the adulthood of a wide coni¬?guration, the sample of the trial theoretical account with existent informations, constructing and proving interfaces, composing and proving studies and, in the terminal system and user testing.

Actual Implementation stage: focal point on edifice webs, put ining desktops and pull offing user preparation and support.

Markus and Tanis ( 2000 ) proposed there ERP execution theoretical account on the footing of ( Soh and Markus, 1995 ) theoretical account for IT undertaking execution. Markus and Tanis ( 2000 ) introduced 4 stage for successful ERP execution.

Undertaking renting stage: concerns with determination devising for spell or no go pick for system, in this stage administration defined the basic concern scenario and solution to the restraints.

The Project ( configure & A ; rollout ) stage: focal point on acquiring needed system, supply preparation and instruction to the end-users of the system, so that system can put in proper and can be utilized by end-users swimmingly.

Shakedown stage: is more frequently a proving stage in which install system tested for identifying and extinguishing any bugs in system and after proving of the system acquire start with the normal unrecorded operations.

Onward & A ; Upward stage: is the station execution stage, which focuses on the maintaining and upgrading of the enforced system, supplying support to the end-user, and measuring the consequence of the enforced system.

Figure.2. ERP System Experience Cycle

( Markus and Tanis, 2000 )

Parr and Shanks ( 2000 ) proposed ERP execution theoretical account by analyzing two instance surveies of ERP execution within a same transnational companies, one was unsuccessful and later a successful 1. These two instance surveies were utilized by Parr and Shanks ( 2000 ) for finding Critical Success Factors that affect ERP execution and they named this theoretical account as Project Phase Model ( PPM ) . PPM consists of 3 stages,

Planing stage: chiefly concern with planning of ERP execution.

Undertaking stage: is the chief phase of the theoretical account, which consists on stairss such as set-up, reengineering, design, constellation and testing, and installing.

Enhancement stage: is concern with the future model of the Implemented ERP bundle.

Figure.2. PPM Model of Implementation

( Parr and Shanks, 2000 )

Al-Mashari et al. , ( 2003 ) proposed a model of ERP execution theoretical account on the based of critical reappraisal of Success factors ( proficient & A ; strategic ) involve in ERP execution and there alignment with concern procedure. Al-Mashari et al. , ( 2003 ) proposed three stage in there theoretical account.

Puting Up stage: focal point on the committedness from the top direction and holding clear ends and vision for ERP execution.

Execution stage: is the most of import and descriptive stage of the theoretical account concentrating from ERP choice phase up-to installing phase.

Evaluation stage: is focus on the post-implementation of the ERP undertaking, sing to the Evaluation of the undertaking.

Figure.2. Taxonomy of Critical Success Factors

( Al-Mashari EL at. , 2003 )

2.3.1 Phase of ERP Project Life Cycle Stages:

After reading literature on ERP undertaking life rhythm phases, writer has decided to take Somers and Nelson ( 2004 ) defined phases for ERP undertaking execution because of their important sum of research on the Critical Success Factors ( CSFs ) , as ( Somers and Nelson, 2001 ; Somers and Nelson 2004 ) proposed their ERP execution theoretical account after doing research on 86 administrations ( Telecom, Education, Manufacturing, Government sector, Banking, etcaˆ¦ ) , writer is rather positive with their proposed and will seek to analysis Somers and Nelson ( 2004 ) phases with other authors as good. These phases are merely concern and discuss with ERP system execution life rhythm within administration, non for ERP system development that is done by seller. Initiation:

Harmonizing to Somers and Nelson ( 2004 ) the first phase for ERP undertaking rhythm is known as induction phase. Initiation phase is the stage where administration took market research and analysis, and locates the most appropriate and sufficient package for company. Parallel to Somers and Nelson ‘s ( 2004 ) , Parr and Shanks ( 2000 ) besides describe induction stage as portion of Project Phase Model ( PPM ) . The PPM consists of three stages be aftering, undertaking and sweetening. The planning stage reference by Parr and Shanks ( 2000 ) includes “ the choice of an ERP ” that is initiation stage describe by Somers and Nelson ( 2004 ) . Initiation stage is besides discuss by Al-Mashari et al. , ( 2003 ) , which is include in two stages ; visioning & A ; planning and direction & A ; leading. Comparing Al-Mashari et al. , ( 2003 ) works with Somers and Nelson ( 2004 ) , it is clear that Al-Mashari et al. , ( 2003 ) discuss foremost two stage of Somers and Nelson ( 2004 ) ( induction and acceptance ) in “ setting-up ” stage. Bancroft et al. , ( 1998 ) besides discuss induction stage in Focus stage of their theoretical account, which besides concern with the planning of pull offing commissions & A ; squads, undertaking rules and programs. Adoption:

Somers and Nelson ( 2004 ) depict 2nd phase as “ acceptance ” phase ; in acceptance stage administration finalise the determination to put in resources that are required to implement ERP undertakings. Planing stage of PPM theoretical account ( Parr & A ; Shanks, 2000 ) , which includes the assembly of maneuvering commission, finding of undertaking range, execution attack and choice of undertaking director and finding of resources, which is similar to adoption stage of Somers and Nelson ( 2004 ) . Markus and Tanis ( 2000 ) besides include stage like acceptance which is called as “ renting ” stage classify as a stage where “ thoughts move to dollars ” , this is the stage where determination for ERP undertaking finalized and approved financess and choice of package bundle. Adaptation:

Adaptation stage is the phase where the Software bundle has been installed in administration and is available for usage in administration ( Somers & A ; Nelson, 2004 ) . Harmonizing Parr & A ; Shanks ( 2000 ) in PPM stage ERP undertaking is seen as an synergistic portion of undertaking theoretical account and can widen to several old ages, this iterative portion will include reengineering, apparatus, design, constellation, proving and installing of ERP system, Parr & A ; Shanks ( 2000 ) show similarity in this stage with Somers & A ; Nelson ( 2004 ) , as after this stage company will get down to work on ERP system. What is different between Somers & A ; Nelson ( 2004 ) and Parr & A ; Shanks ( 2000 ) position of thought, is that Parr & A ; Shanks have constellation and installing of package bundle within company but Somers & A ; Nelson do n’t.

Shakedown stage has been described by Markus and Tanis ( 2000 ) , which switch between version and credence stage in Somers and Nelson ( 2004 ) . Shakedown stage is the clip between when system has been installed in administration and administration starts to utilize that system in unrecorded environment.

Figure.2. ERP Project Life Cycle Stages

( Somers and Nelson, 2004 ) Credence:

Acceptance phase is the stage when ERP system is employed by administration ( Somers and Nelson, 2004 ) . Al-Mashari et Al. ( 2003 ) depict execution stage which include stairss from all the phases of Somers and Nelson ( 2004 ) up to acceptance phase, but major difference is that its focal point on constellation and Al-Mashari et Al. ( 2003 ) besides includes stairss like preparation and communicating in order to accept ERP system by administration. Routinization:

The stage where ERP system is no longer treats as something new or something out of normal in administration, this stage is known as Routinization by Somers & A ; Nelson ( 2004 ) . Markus and Tanis ( 2000 ) specify this stage as “ onward and upward ” in there theoretical account, forth and upward is the stage when administration learn and recognize the benefits of ERP systems and use the ERP system on everyday footing, until new version is released. Infusion:

Infusion is the last phase for Somers & A ; Nelson ( 2004 ) undertaking life rhythm. Infusion is the phase where administration utilizes ERP system at its full potency ( Somers & A ; Nelson, 2004 ) . Evaluation stage is the last stage of project life rhythm for Al-Mashari et Al. ( 2003 ) , rating stage include rating of undertaking in footings of public presentation and direction of undertaking. Harmonizing to Al-Mashari et Al. ( 2003 ) rating stage is the most critical phase for guaranting success of ERP system, similar to Somers and Nelson ( 2004 ) last phase in which the system is determined to be an extract or non. Discussion:

Comparing the Somers and Nelson ( 2004 ) undertaking life rhythm with other writers theories on ERP undertaking life rhythm, its been founded that Somers and Nelson ( 2004 ) had missed out some of import points such as design, installing and constellation of the ERP system. Parr and Shanks ( 2000 ) depict these undertaking phases in their ERP undertaking life rhythm. Few other writers ( Al-Mashari et al. , 2003 ; Mabert et al. , 2003 ; Markus & A ; Tanis, 2000 ; Hong & A ; Kim, 2002 ) besides stressed the importance of constellation and installing stages. Author will concentrate the parametric quantities such as design, installing and constellation while carry oning research & A ; interviews, and reference any information related with design, installing and constellation in Adaptation stage of Somers & A ; Nelson ERP Project Life Cycle Stages:

2.4 Identifying cardinal Actors and Activities that consequence ERP Execution:

ERP desire benefits can merely be achieve, when ERP systems are decently implemented, and execution of ERP systems are rather hard. Many companies discontinue their execution plans for ERP undertakings or few of them merely achieve some of the aims they aim from the undertaking ( Sammon and Adam, 2004 ; Al-Mashari et al. , 2003 ) . Numbers of ERP undertakings do non ensue in desire effects & A ; benefits, and even though Numberss of undertakings end up in forsaking ( HollandA et al. , 1999 ) . Therefore to understand how administrations can implement ERP systems undertaking successful, one should understand & amp ; recognize the factors that effects ERP systems. There are several factors that can act upon ERP undertaking execution such as ; Cross-functional communicating & A ; coordination, undertaking direction, ERP package development & A ; constellation, Capabilities of top degree direction ( managers ) & A ; human resource ( employees ) and last but non least change direction ( Davenport, 1998 ; Holland and Light, 1999 ; Parr et al. , 1999 ) .

2.4.1 Key Actors of ERP Undertakings: Top Management Support:

Project life rhythm of ERP systems requires support from top direction. Exceed degree direction support & A ; committedness is really of import and indispensable success factors for ERP undertaking execution, as top direction have to oversee the advancement and steer the way to execution squads ( Somers and Nelson, 2004 ) . ( Sumner, 1999 ; Al-MashariA et al. , A 2003 ; Bingi, 1999 ) argues that ERP undertaking should be aligned with strategic & amp ; corporate concern ends and it should have support and blessing from top direction. Reward base or fillips basal direction can back up achievement of undertaking successfully ( Wee, 2000 ) . Strong committedness from top direction is required for successful execution. Attitudes and attacks of high degree executives non merely impact the undertaking life rhythm but besides in-between direction ( team leader and undertaking directors ) ( Davenport, 2000 ) . It is duty of high degree executive to sort benefits and demands of undertaking publically to all sections of company ( Wee, 2000 ) . Committedness and engagement of senior direction is required with willingness to apportion value resource for the execution of ERP undertaking ( Holland et al. , 1999 ) .

Manager should give legal values to new ends and aims, shared the administration vision, and pass on the function of new system and structures to stop users ( employees ) ( Nah et al. , 2001 ) . Strong leading, committedness and engagement by high degree direction required for successful execution of ERP undertaking ; a designated planning commission dwelling of executive direction should be develop, holding chief undertakings such as endeavor integrating, understands ERP, to the full supports the cost, demands payback, and title-holders the undertaking ( Umble EL at. , 2003 ) . Al-MashariA et Al, A ( 2003 ) argues about committedness for leading & A ; top direction for puting up way for concern, puting up vision, developing of creativeness and energy in employees and using the capablenesss of ERP systems. Al-MashariA et alA ( 2003 ) besides urges that top direction support and committedness does non stop with induction of undertaking, but it must be prolonged till the fulfillment of the needed aims of the undertaking. Steering Committee or Cross-functional Teams:

Project life rhythm of ERP requires transverse functional coordination of administration all map every bit good as with undertaking directors ( Shanks el at. , 2000 ; Summer, 1999 ) .The deficiency of coordination may outcome in hold of execution and administration struggles, which is rather serious issue taking towards failure of undertaking ( Kim el at. , 2005 ) . Steering commission is rather important at initial phases of the undertaking life rhythm, as maneuvering commission as to do item undertaking program, scheduling the undertaking undertaking, and assign duties ( Bingi et al. , 1999 ; Umble EL at. , 2003 ; Rosario, 2000 ; Nah el at. , 2001 ) . Steering commission consists of representatives from all administration sections such as ; senior direction, functional director, undertaking director etc and stop user of ERP system ( Somers & A ; Nelson, 2004 ) . Successful maneuvering commission is a cross functional squad and contains member who are most knowing in administration ( Umble et al. , 2003 ) . Project Champion:

Harmonizing to Somers & A ; Nelson ( 2004 ) Project Champion function is usual related with invention of engineering ; project title-holder should hold the capableness of leading, selling and facilitation. Undertaking title-holder should recognize both the administration concern and implemented engineering and play function of alteration title-holder for project life rhythm. ( Somers & A ; Nelson, 2001 ; Nah el at. , 2001 ; Sumner, 1999 ) stated that undertaking title-holder should be appointed from executive degree of an administration, which possesses good cognition and bid over administration operations ; as undertaking title-holder is straight apt and answerable for undertaking result. Rosario ( 2000 ) stated that the occupation of undertaking title-holder is critical and important throughout ERP project life rhythm. So hence Sumner ( 1999 ) argues that it is of import for undertaking title-holder to hold effectual and efficient cognition on concern accomplishments, so concern position of the undertaking stay alive. Dramatically leading is important for success of undertaking as good. Leader must continuously endeavor to work out issues and jobs. Project Team:

The undertaking squad included internal staff ( employees with proficient and strategic accomplishments ) , advisers and alteration director ; “ undertaking squad is transverse functional, and has a ‘team charter ‘ detailing the doctrine for the undertaking ” ( Holland el at. , 1999 ) . A undertaking squad that is transverse functional is largely successful and contain extremely knowing employees of the administration ( NahA et al. , 2001 ; Somers & A ; Nelson, 2001 ) . It is rather of import to hold a undertaking squad with the mixture of inter-organisational associates and external advisers ( Sumner, 1999 ) . Undertaking squad members should portion information both internal and external and project squad members should concentrate merely on undertaking demands, undertakings and aims as their top precedence ( Wee, 2000 ) . Competence undertaking squad, which has technological competency every bit good as concern competency of undertaking, is quite critical for ERP success ( Somers & A ; Nelson, 2004 ) . Advisers:

Advisers plays of import function in staffing many undertakings execution. “ The Success of the undertaking depends strongly on the capablenesss of the advisers ” ( Bradley, 2008 ) . Holland et al. , ( 1999 ) argued that company should hold proficient experts for ERP constellation and execution, which besides helps administration for implementing alteration factor within company. The mixture of internal employees and external advisers is normally the best option for carry oning these types of undertakings. If administration does non hold in house expertness of undertaking, so administration should travel towards outside advisers for pull offing ERP system execution ( Kim el at. , 2005 ) . Company that are implementing ERP system and want to implement good, so that company should work good with sellers and advisers to work out jobs ( Nah el at. , 2001 ) . Hiring external advisers provide administration to excess outside expertness and wide-range of cognition of different faculties. External adviser performed critical occupations such as urging suited solution for jobs and pull offing execution of ERP system ( Somers & A ; Nelson, 2004 ) . Sellers:

Its is rather important for implementing administration to hold good partnership with seller, as good partnership will take to hold a long unrecorded relationship and aid to accomplish strategic benefits ( Davenport, 1998 ; Somers & A ; Nelson, 2001 ) . With new engineering, it is frequently critical to get external expertness, including seller support, to ease successful execution ( Sumner, 1999 ) . When company needs upgrading, company may affect seller forces, who can back up cardinal activities such as continues concern environment, constructing user accomplishments and station execution benefits appraisals ( Nah el at. , 2001 ) . Organisation direction must seeks for inquiries sing to vendor ; such as seller path record, vision of the hereafter, market focal point and whether seller is strategically aligned with administration ( Bingi el at. , 1999 ) . Nah EL at ( 2001 ) argues that company that is implementing ERP system should work good with sellers during the execution stage and after the execution every bit good. Holland and Light ( 1999 ) say that seller tool could be rather of import for custom-making concern procedure for administration even without altering bing package systems. In-house IT specializers:

Like wise, several ERP surveies ( Lee and Lee, 2004 ; Markus and Tanis, 2000 ) argued that the in-house IT professionals must be equal with cognition or experience of ERP undertakings, for doing ERP execution successful. Such skill-full employees are rather important for the organisation in post-implementation stages of the undertaking ( Markus and Tanis, 2000 ) . As the function of IT is going incrementally rather important for companies, that ‘s why there is a demand for IT section to transformed from normal function of supplying support to office operation into more formal manner ( Ii¬?nedo, 2006 ) .

2.4.2 Cardinal Activities: Clear vision, ends and objectives/ Planning:

A clear concern program and vision to maneuver the way of the undertaking is needed throughout the ERP life rhythm. Administration that attempt to put in an ERP system without specifying clear vision and without considerate of concern propositions can turn integrating procedure into catastrophe, no affair how compatible selected package bundle is ( Davenport, 1998 ) . Davenport ( 1998 ) argues that the logic of ERP systems may conflicts with the concern logic and consequence may be terminal with execution failure or destabilized competitory place. Al-MashariA et al. , ( 2003 ) and Markus et al. , ( 2000 ) besides argue that without clear way or ends and careful strategic planning, consequence in failure for ERP undertaking life rhythm. Well planned strategic ends and marks keep ERP undertakings on path through out its execution. Gargeya and Brady ( 2005 ) because of high investing and hazards in ERP undertakings, extremely sophisticated planning is required with no loose borders. Strategic Plan that outlines the proposed strategic resources, cost, hazards and timeline is critical for ERP undertaking, as it will assist to maintain focal point on cardinal concern benefits ( Wee, 2000 ) .

Clear concern theoretical account should be developed, that would assist administration in execution of undertaking ; but before this administration should place its ends and benefits, so it could be tracked ( Holland et al. , 1999 ) . Business demands and demands should be aligned with the undertaking mission and this could merely be achieved by holding proper concern program that would do occupation easier ( Nah el at. , 2001 ) . Preliminary phase of any undertaking should be conceptualisation of ends and accomplishable way for accomplish those ends, and so those ends should be advertised and clarified so that everyone could understand the general intent and way of the undertaking. Lack of clear programs and ends in ERP undertaking life rhythm could ensue in increase of undertaking range and clip ( Somer and Nelson, 2001 ) . Administration required peoples who create clear and convincing vision for implementing ERP undertaking, so that administration could run in a manner that would authorise employees, fulfill client and provider. Organisation clearly define why ERP system is being install, by define clear definitions of outlooks, deliverables and ends ( Umble et al. , 2003 ) Project Management:

ERP undertaking life rhythm requires careful strategic dialogues and be aftering with all subdivisions that involves suited undertaking direction techniques, methods and construction ( Bingi et al. , 1999 ) . Undertaking director should be capable and competent in tactical, functional and strategic undertaking direction activities, in order to pull off ERP undertaking successfully ( Al-MashariA et al. , 2003 ) . Excellent undertaking direction is necessary, a individual employee or group of employees should be authorised to drive success in undertaking direction ( NahA et al. , A 2001 ) . Initially undertaking should be defined by its mileposts, with its critical way determined ( Holland et al. , 1999 ) .

Proper undertaking direction should be implemented with deadlines that should assist ERP undertaking to remain within budget, range, agenda and on-time ( Wee, 2000 ) . Project direction should be managed with aid of human resource section, which provide disciplined preparation to employees. Plus good defined undertaking and precise appraisal is required to run undertaking ( NahA et al. , A 2001 ) . The huge combination of hardware and package, plus human issues of company makes ERP undertakings highly complex, which requires project direction proficiency ( Somers and Nelson, 2001 ) . Training and Education of Employees:

Davenport ( 1998 ) argued that the preparation should include all the characteristics of the ERP systems, preparation should be continuously provided within administration with one basic purpose & A ; rule of reassigning cognition. “ ERPA systemsA are highly complex and demand strict preparation ” ( Bingi el at. , 1999 ) . Training plans and planning of instruction have important consequence on the success of ERP execution, should be run through the undertaking life rhythm, to back up administration aims ( Mabert el at. , 2003 ; Sumner, 2000 ; Wee, 2000 ) . Mabert el at. , ( 2003 ) argues that be aftering educational and preparation activities allow companies to understand graduated table of costs involved in the procedure of execution. Using in-housing preparation, support user to larn how new system will convey alteration in concern procedure of the company ( Sumner, 2000 ; Somers & A ; Nelson, 2004 ) . Lack of user preparation has been one of the chief barrier in the success of ERP execution ( Markus and Tanis, 2000 ; Al-Mashari EL at. , 2003 ) . Somers & A ; Nelson ( 2004 ) stated that preparation is chiefly concern last phases of execution but besides be seen as of import factor throughout undertaking rhythm. Cross-functional communicating & A ; coordination:

Efficient information sharing & A ; communicating is rather important and of import for success of ERP execution ( Bingi el at. , 1999 ; Gargeya and Brady. , 2005 ) . Communication comprises the official encouragement of undertaking squads and the advertizement of undertaking development to all sections of the organisation ( Holland et al. , 1999 ) . Management should pass on the range, ends, nonsubjective and activities of undertakings at every degree of administration, as it is really of import to do undertaking advancement more efficient ( Sumner, 1999 ; Wee, 2000 ; Bradley, 2008 ) . This activity is of import from induction through the credence phases harmonizing to Somers and Nelson ( 2004 ) . End user input ( demands, remarks and reactions ) should be managed decently ( Rosario, 2000 ) . In order to avoid the communicating failure, company should hold undertaking execution policies for information sharing ; such as e-mailer system, but of import affair should be addressed by telephone or by face to confront meetings ( Al-Mashari EL at. , 2003 ) . Business procedure reengineering ( BPR ) or Customization:

Harmonizing to definition of ( Hammer and Champy, 2001 ) BPR is “ the cardinal rethinking and extremist redesign of concern procedures to accomplish dramatic betterments in critical, modern-day steps of public presentation, such as cost, quality, service and velocity ” . Continuing the originality and singularity of ERP softwares requires the outgo and disbursal of Business Process Reengineering, peculiarly for large prohibition execution scheme ( Kamhawi, 2009 ) . Umble EL at. , ( 2003 ) stated that the ERP execution may requires the reengineering to concern procedures or even new concern processes has to developed for in order to back up administration ends. ERP execution and BPR activities should be closely connected ( Al-Mashari and Zairi, 1999 ) . BPR is required and of import in the initial phases of the undertaking ( Somers & A ; Nelson, 2004 ) . It is rather indispensable for administration to aline its concern procedure with the ERP system execution and enforced package should non modify every bit far as possible ( Sumner, 1999 ; Holland et al. , 1999 ; Bingi et al. , 1999 ; Umble EL at. , 2003 ) . Holland & A ; Light ( 1999 ) argues that concern and its procedure has to alter instead so implemented package bundle. Alteration should be avoided within enforced system to cut down mistakes, so that company could take advantage of newer versions ( Rosario, 2000 ; Nah el at. , 2001 ) . Kamhawi ( 2009 ) explain that administration that have good abilities of BPR, will implement ERP system decently and swimmingly. Change Management:

Most user friendly and flexible ERP systems will coerce its regulations and ordinance on company ‘s construction, civilization and scheme and without uncertainty ERP execution activates doctrine of alteration in administration civilization ( Umble EL at. , 2003 ) . Umble EL at. , ( 2003 ) and Al- Mashari EL at. , ( 2003 ) urges that unluckily senior degree direction underestimate ERP system as a simple package bundle and execution as formal technological challenge ; they do non understand that ERP system will fundamentally alter the manner administration operates. Organizations should hold a strong corporate individuality that is unfastened to alter ( Nah el at. , 2001 ) . To advance alteration direction attempts in administration, user should be involved in design and execution concern procedure and ERP system ; and initial preparation and instruction on system should be provided to stop user ( Bingi et al. , 1999 ; Holland et al. , 1999 ) . Legacy System:

In ERP execution, current bequest systems have to be carefully evaluated, analysed and dei¬?ned to decide the graduated table of jobs that company may run into during execution ( Holland and Light, 1999 ) . Administrations besides find that the ERP systems support administration in order to acquire rid from there legacyA systems ( Bingi el at. , 1999 ) . Steady and balanced concern bequest system puting is important ; Organisation IT system, concern procedure, construction and civilization affect the success of ERP undertaking life rhythm ( Nah el at. , 2001 ) . Al-Mashari EL at ( 2003 ) argues that if company ‘s bequest system is complex and complicated, so the degree of organizational and proficient alterations will be high and frailty versa.

2.5 What is success for ERP Projects?

Baccarini ( 1999 ) describes the success of Projects depend on two constituents:

Project Management Success

Project Product Success

2.5.1 Project Management Success:

Project Management success is chiefly concern with the success of project direction procedure with the respect to completion of undertaking “ within clip ” , “ within budget ” , and “ harmonizing to required specification ” ; these three dimension of success besides reference by assorted writers ( Duncan 1987 ; Thomsett 2003 ) and point out the degree of ‘effectiveness of undertaking executing ‘ ( Pinkerton, 2003 ) . In position of Baccarini ( 1999 ) these three dimensions are non equal to mensurate the success of undertaking direction, Baccarini ( 1999 ) argues that dimension like satisfaction of undertaking stakeholders and quality of the undertaking direction should be consider for mensurating success.

Figure.2. Project Management Success Model in Pictorial format

( Baccarini, 1999 )

2.5.2 Project merchandise Success:

Project merchandise success is concern with the success of end-product of the undertaking and user satisfaction ( Baccarini, 1999 ) . Although results of undertaking direction success and project merchandise success are inseparable linked ( Pinkerton, 2003 ) and relationship between them is weak as if undertaking is over clip and/or budget, so undertaking can see to be project direction failure but the outcome merchandise may or can be success ( Baccarini, 1999 ) .

2.5.3 The DeLone and McLean Information System success theoretical account:

In 1992 DeLone and McLean proposed a theoretical account on Information System ( IS ) success, which contribute important function in measuring of IS project success ( Seddon et al. , 1999 ) . DeLone and McLean proposed there theoretical account on the bases of both empirical and theoretical research by reexamining 100 documents incorporating empirical IS success steps publish in seven publication during 1981-1987. In the “ D & A ; M IS Success Model, “ systems quality ” counts proficient success ; “ information quality ” counts semantic success ; and “ usage, user satisfaction, single impacts, ” and “ organisational impacts ” step effectivity success ” ( DeLone and McLean, 2003 ) . DeLone and McLean ( 1992 ) extracted six dimensions after reexamining documents, which are as follow and show in figure 2.6.

System Quality: concern with the measuring of the information processing system by itself. Measuring how much an IS contributed to organisation

Information Quality: concern with the measuring of information system end product, instead so mensurating the quality of information system public presentation.

Information Use: concern with the measuring of the recipient ingestion of the end product of an information system, such as by usage of information system studies.

User Satisfaction: concern with measuring of the receiving system answer to the use of the end product for information system,

Individual Impact: concern with the measuring of the consequence of information on the receiver, impact could be indicate as if IS provide user better understanding to do determination, improved determination doing productiveness and bring forth a alteration in user activity.

Organizational Impact: concern with the measuring of the consequence of information on organisational public presentation.

Figure.2. IS Success Model

( DeLone and McLean, 1992 )

In 2003 DeLone And McLean updated their IS Success Model, DeLone and McLean ( 2003 ) had made following few updates in their theoretical account, which are as follow and show in figure 2.7 every bit good.

Figure.2. Updated IS Success Model

( DeLone and McLean, 2003 )

DeLone and McLean ( 2003 ) had added ‘Service quality ‘ dimension in the field of information and system quality dimensions. Harmonizing to DeLone and McLean ( 2003 ) “ quality has three major dimensions: ‘information quality, ‘ ‘systems quality, ‘ and ‘service quality ‘ “ . Every one of these dimensions should be measured individually, as if they measured jointly, so they will impact ‘use ‘ and ‘user satisfaction ‘ dimensions. Use dimension was placed side with new dimension of ‘Intention to utilize ‘ . Harmonizing to DeLone and McLean ( 2003 ) “ ‘intention to utilize ‘ is an attitude, whereas ‘use ‘ is behaviour ” . DeLone and McLean ( 2003 ) besides argue that dimension of ‘use ‘ and ‘user satisfaction ‘ is closely connected and interrelated. For accomplishing greater user satisfaction, it is indispensable to hold positive experience with ‘use ‘ . In the same manner better user satisfaction will assist to increase ‘intention to utilize ‘ and ‘use ‘ every bit good. New dimension of ‘Net Benefits ‘ is been introduced by DeLone and McLean ( 2003 ) , holding combination of old dimension like ‘Individual impact ‘ and ‘organizational impact ‘ . Harmonizing to DeLone and McLean ( 2003 ) better ‘use ‘ and ‘user satisfaction ‘ will ensue in ‘Net Benefits ‘ .
