Abstract
Abstract planning systems

  • Examines(檢查) the process of system review during the postimplementation review (PIR), and identifies factors that contribute to high-quality PIRs.

  • In two organizations (fictitious named as):

    • MANU

    • UTIL


Introduction
Introduction planning systems

  • The two factors that influence the process of system development:

    • Organization performance

    • User perceptions about the system after its implementation and continued use in an organization.


Introduction1
Introduction planning systems

  • The quality of PIR:

    • Heavily dependent on the quality of the implementation process itself and on its effectiveness.

    • Could represent a key element in the examination of the relationship between system implementation and the realization of anticipated benefit form the use of ERP.


Erp systems implementation
ERP systems implementation planning systems

  • The major advantage of ERP systems

    • The application software suites, which still service accounting conventions and needs.

    • Integration of all information flowing through a company.


Erp systems implementation1
ERP systems implementation planning systems

  • Critical factors for the success of an ERP:

    • Top management support.

    • An effective implementation team.

    • Organizational-wide commitment.

    • The effective resolution of misalignments between organization needs.

    • ERP package functionality.


Expected benefit from erp systems implementation
Expected benefit from ERP systems implementation planning systems

  • ERPs are designed to help manage:

    • organizational resources in an integrated manner.

  • Intangible benefits:

    • Related to internal integration, improved information and processes, and improved customer service.

  • Tangible benefits:

    • Related to cost efficiencies in inventory, personnel

      , procurement and the time needed to close books.


Factors of failure in erp systems implementation
Factors of failure in ERP systems implementation planning systems

  • Meta group(1999):

    • The average implementation time for a full-blown ERP system was 23 months, at a cost of US$10.6 million for the implementation and another US$2.1 million for maintenance over a 2 year period.

  • Several studies exist of companies that were led into severe financial distress because of system integration problems after the implementation of ERP systems:

    • Unisource Worldwide、Dell Computer、 Dow Chemical、Hershey Food Cooperation…


Factors of failure in erp systems implementation1
Factors of failure in ERP systems implementation planning systems

  • The computer integration problems.

    • The implementation ERP systems suffer from system integration problems.

    • The lack of alignment between people, processes, and new technology.

  • System led implementations have a higher incidence of failure compared to those that are business led.

Factors of failure in ERP systems implementation planning systems

A well-planned and well-executed PIR of the system implementation should assist organizations to effect needed changes in organizational plans and process.

  • Avoid implementation risks

  • Realize potential operational and strategic benefits.

2 2 pir of erp systems
2.2 PIR of ERP systems planning systems

  • PIR is used to improve the design and effectiveness of an already developed system.


2 2 1 pir in capital budgeting research
2.2.1 PIR in capital budgeting research planning systems

Capital budgeting literature define PIR or PCA as a feedback device.


Pca postcompletion audit
PCA(postcompletion audit) planning systems

  • Use of quantitative model to identify poorly performing assets.

  • Use of regular periodic review versus one-time review.

  • Extent of documentation of postaudit(事後審計) procedures.

  • Extent to which postaudit procedures were applied as a percentage of capital project postaudited by a firm.

  • Use of formal versus informal postaudit procedures


The level of postauditing sophistication is an important issue
The level of postauditing sophistication is an important issue.

  • The sophistication postaudit were useful in making decision abandon, continue, or enhance project or to suggest changes to improve future project selection


Pir in is literature
PIR in IS literature issue.

  • PIR for IS has also been presented in the early system implementation literature.

  • PIR should include an evaluation(審計) of system impacts using a long-term view, be conducted(經營) by user, and formalized.


Three major stages after erp implementation
Three major stages after ERP implementation issue.

  • Company may experience a 3-6 month productivity decline

  • Use 6-8 month to involve skills development, structural change, process integration, and add-on technologies that expend ERP functionality.

  • Involve business transformation,


Four different organizational interventions for erp implementation
Four different organizational interventions for ERP implementation

  • Business process reengineering(重組)

  • Detail requirements specification(詳述) for system selection.

  • System testing prior(預先) to implementation.

  • Monitoring of the system after it’s implementation(完成).


Research proposition
Research Proposition implementation

  • The quality of post-implemantation review that is carried out in an organization will have a significant influence on the realization of expected outcomes from the use of ERP system.


Research method
Research method implementation

  • Step1:Personal interviews (carried out with corporate directors of information technology in both companies)

  • Step2:Second interview with the same individual followed for further(深入) explanations.

    *The semi-structured interview were guided by an interview protocol.


Interview protocol 1
Interview Protocol (1) implementation

  • What were the driving force for the system change to an ERP architecture?

  • Was there a strategic plan in place to guide the deployment of the new ERP system? What were the specific principles that guide system development as part of the strategic?

  • Looking back at the implementation process, what were those factors that critically determined implementation success or failure?


Interview protocol 2
Interview Protocol (2) implementation

  • On a postimplementation basis, what action were taken to enhance system functionality, review the system’s service potential, or evaluate user acceptance?

  • Could specific success factors be identified that were discovered during the postimplementation phase of the system life cycle? What tools were used for their measurement, if any?

Internal question of manu
Internal question of MANU implementation

  • System need of upgrading

  • The cost of associated with these systems

  • Data inconsistency

  • Fragmentation


External questions of manu

  • Configure the program

  • The benefits of Implementation of the SAP system


Why util implements erp
Why UTIL implements ERP? implementation


Why util implement the erp system
Why UTIL implementationImplement the ERP system?

  • Primary objective –

    a. Improving operation efficiencies

  • Matched a strategic plan -

    a. Customized reporting

  • The effect of Implementation the ERP system

    a. Hindered process integration

    b. Limited the process


Util failure reasons
UTIL failure reasons implementation

  • The top management’s wrong policy

  • Lack of the in-house technical expertise

  • Lack the overall understanding of business process

  • The implementation was turned over to the IT


What the util comprehend from the failure
What The implementationUTIL comprehend from the failure

  • System implementation effort has to be viewed as an ongoing process

  • It’s viewed as an overall long-term effort for the development of a new business model




4 4 1 evaluation of system fit with organizational strategic vision
4.4.1 Evaluation of system fit with organizational strategic vision

  • MANU

    • The ERP system implementation was part of a larger reorganization effort

    • System was viewed as a medium to ensure competitive advantage, facilitate corporate expansion

    • For postimplementation - continuously evaluate system fit and expansion

  • UTIL

    • ERP system was much more limited in scope, combined with idiosyncratic reporting requirements

    • Low level of fit between the SAP system and the organization’s objectives

    • System was not viewed as critical for attainment of any business objectives


922645

922645 vision


4 4 2 project planning

MANU: evaluated and changes instituted in subsequent implementation teams

UTIL: no formal evaluation of project panning but instituted changes after initial failure

4.4.2 Project planning


4 4 3 evaluation of infrastructure development

MANU implementation teams

Information infrastructure was considered critical for survival

Data Warehouse

UTIL

Information infrastructure was not a driver for competition

Identified significant deficiencies in helping the organization meet its current objectives

4.4.3 Evaluation Of Infrastructure Development(基礎建設的評估)


4 5 review of driving principles for the deployment of the enterprise system

MANU implementation teams

Has formal review of process integration, global support, reevaluation pf initial system

UTIL

Has no formal review of process integration, business justification

4.5 Review Of Driving Principles For The Deployment Of The enterprise system(事前的部署)


4 6 effectiveness of misfit resolution strategies

MANU implementation teams

Evaluate process simplicity and implemented 80:20 rule

UTIL

Evaluated process and reporting inadequacies and developed “workaround” to bypass system deficiencies

4.6 Effectiveness of misfit resolution strategies(有效的解決對策)

4 7 evaluation of attained benefits 1
4.7. Evaluation of attained benefits implementation teams (1)

  • The success of the system implementation effort in terms of attaining anticipated benefits depended on two critical factors:

    (a) The design of the system around the enterprise supply chain.

    (a) →provided the opportunity for increased efficiency in

    (a) → operations and had a pervasive effect throughout the whole

    (a) → enterprise.

    (a) →related to improvements in customer service.


4 7 evaluation of attained benefits 2
4.7. Evaluation of attained benefits implementation teams (2)

  • The success of the system implementation effort in terms of attaining anticipated benefits depended on two critical factors:

    (b) An early focus of the system design effort on quantifiable

    (b)business outcomes.

    (b)→has forced MANU's business units to make decision that

    (b) →eliminated nonvalue adding process or to simplify complex

    (b) →processes into a more simple structure that was common

    (b) →across the whole company.


4 7 evaluation of attained benefits 3
4.7. Evaluation of attained benefits implementation teams (3)

  • MANU -

    → An important PIR activity that MANU carried out is to formally

    → assess customer satisfaction using specially design customer

    → surveys and the results of those surveys were subsequently used

    → to further institute necessary changes in business processes.

    → is currently embarking on a “supply chain transformation”

    → initiative, building on its enterprise infrastructure and on supply

    → chain directed applications (including both Web-based and Web-

    → enabled applications).


4 7 evaluation of attained benefits 4
4.7. Evaluation of attained benefits implementation teams (4)

  • UTIL adopted its ERP system -

    →the implementation problems that were encountered and its

    → process misfits with system requirements did not allow the company

    → to realize these desired benefits.

    →there was no formal activity in place to evaluate attainment of

    → benefits on a postimplementation basis.

    → primarily due to significant user complaints relating to process

    → inefficiencies introduced by the new system.


4 8 evaluation of learning 4 8 1 user training 1
4.8. Evaluation of learning implementation teams 4.8.1 User training (1)

  • After the installation of the SAP system -

    Users were overwhelmed and not well prepared for the process

    changes brought about by the enterprise system.

    → for instanceIn MANUsuch asentering a sales order. Customers

    →did not receive the products they had ordered and experienced

    → delays in delivery.

    → Part of the problem was due to the fact that employee training

    → was initially constrained only to the functionality within SAP that

    → users needed to do their jobs,without being provided with a clear

    → and overall view of how the software operates.


4 8 evaluation of learning 4 8 1 user training 2
4.8. Evaluation of learning implementation teams 4.8.1 User training (2)

  • After the installation of the SAP system -

    Users were overwhelmed and not well prepared for the process

    changes brought about by the enterprise system.

    → MANU responded to these initial problems by radically radically

    → changing its training methods, instituting a certification process,

    → where employees would have to pass a certifying test before

    → given access to the system.


4 8 evaluation of learning 4 8 1 user training 3
4.8. Evaluation of learning implementation teams 4.8.1 User training (3)

  • After the installation of the SAP system -

    Users were overwhelmed and not well prepared for the process

    changes brought about by the enterprise system.

    → UTILwere just trained on performing specific functions within

    → SAP that were necessary for their day-to-day responsibilities.In

    → conclusion, the steep learning curve associated with the use of

    → a complex enterprise system has led to errors and delays,

    → significantly obstructing both companies' ability to realize

    → anticipated benefits from the use of their ERP system.


4 8 evaluation of learning 4 8 2 knowledge transfer 1
4.8. Evaluation of learning implementation teams 4.8.2 Knowledge transfer (1)

  • Knowledge transfer in a system's life cycle is also presented in the professional literature as a critical factor in managing the dependencies between people, business processes and events, and knowledge domains.

  • MANU has discovered on a postimplementation basis that it must ensure the continuity in the skills and knowledge acquired during the implementation process in order for the system to be used effectively and provide the anticipated benefits.


4 8 evaluation of learning 4 8 2 knowledge transfer 2
4.8. Evaluation of learning implementation teams 4.8.2 Knowledge transfer (2)

  • The absence of such continuity in UTIL, due to the lack of system and process documentation during the implementation of the system, contributed to dissatisfaction with the system, no acceptance by users, and in project failure.


4 9 overall cultural and organizational effects 1
4.9. Overall cultural and organizational effects implementation teams (1)

  • In both UTIL and MANU, the postimplementation phase of their ERP systems necessarily led to changes in organizational power relations.

  • In UTIL, the IT department gained more power over user departments, because the second implementation effort is under the direct supervision of the IT manager who has direct reporting responsibility to the CEO.

  • (UTIL) The IT department has recruited individuals with both technical expertise as well as process expertise in the particular industry in anticipation of the new system implementation effort.


4 9 overall cultural and organizational effects 2
4.9. Overall cultural and organizational effects implementation teams (2)

  • In Manu The company has changed its structure and created a number of competence centers so that its customer service, logistics, materials management, supply chain planning, and IT groups can best work under a common umbrella to effectively address post-ERP implementation challenge.

  • (MANU) In the literature, competence centers are presented as important not only for ERP software maintenance, but also as an invaluable resource for user education, support, and to promote ongoing improvements in business processes.


4 9 overall cultural and organizational effects 3
4.9. Overall cultural and organizational effects implementation teams (3)

  • All of the above factors had greatly influenced the implementation of the ERP systems at the two companies and had shaped the user‘s predisposition toward the system after its initial implementation.

  • As a result, based on the case findings, an overall conceptual model of ERP postimplementation effectiveness may be presented that could be useful in future empirical investigations.

Conceptual definition of the concept of pir quality 1
Conceptual definition of the concept of PIR quality (1) implementation teams

  • The quality of PIR that has an important effect on business performance.

  • In general, as demonstrated in Fig.1, a high-quality PIR process should enable an organization to maximize the effectiveness of intervention during the implementation of the system and attain postimplementation effectiveness.


Conceptual definition of the concept of pir quality 2
Conceptual definition of the concept of PIR quality (2) implementation teams

  • The most important culprits in a problematic ERP implementation are lack of user training and failure to completely understand how enterprise applications change business processes (Wilder and Davis, 1998).

  • It is also emphasized by system professionals that for an organization to turn around after initial failure, it must engage in PIR that will assist in better defining the scope of the project and improving user training and acceptance of the system.

  • This situation was demonstrated very eloquently in the case of UTIL.


Conceptual definition of the concept of pir quality 3
Conceptual definition of the concept of PIR quality (3) implementation teams

  • Organizations may expect to gain strategic advantages from the implementation of ERP system. Such strategic advantages could be associated with (a) increased data accuracy that facilitates interactions with customers and suppliers and (b) improvement in the availability and quality of information due to improvements in business processes (Mabert et al., 2001).


Conceptual definition of the concept of pir quality 4
Conceptual definition of the concept of PIR quality (4) implementation teams

  • A well-planned and well-executed PIR of the ERP system implementation, therefore, should assist organizations to effect needed changes in organizational plans and processes and realize potential operational and strategic benefits.

  • The concept of “quality of PIR”, could be defined by the extent to which an organization adopts the set of PIR dimensions identified in Table2.


Conceptual definition of the concept of pir quality 5
Conceptual definition of the concept of PIR quality (5) implementation teams

  • In the conceptual definition of PIR quality, therefore, it is the cumulative influence of these practices that should most strongly influence outcomes.

  • It remains an important empirical question, therefore, to further operationally define the concept of PIR quality, examine the relative importance and contribution of individual practices on PIR quality, and test their influence on outcomes of postimplementation effectiveness.
