ERP framework (Critical decisions for implementation)
Six critical decisionsAssumptions
Keep any customization to a minimumEnsure that the business processes directly supported by the software packageHave an ERP package with an intuitive and easy-to-use interface to minimize training and user support costs

Program team structure
The team structure can be broken down into four categories
Isolated Function, A-Team, and Lightweight
Require fixed personnel on each function , financial and technical resources to maintain
HeavyweightFlat management hierarchyThe highest chance
![Page 16: Critical decisions for ERP integration: Small business issues 資碩專一 98756011 李怡夢 98756003 顏臺良 International Journal of Information Management(2009) Management](https://reader035.vdocuments.net/reader035/viewer/2022081505/5697bff91a28abf838cbfb13/html5/thumbnails/16.jpg)
Alternative team structuresMethod Description Advantages Disadvantages
Isolated function
Participants from each functional area are responsible for their own implementation and use of the software.
1. Resources of the organization are focused on the implementation2. They have the most knowledge about their business processes and will be very knowledgeable end-users later
1.insufficient communication between functional groups2.workflows that span multiple functional modules may be incorrectly implemented, or may not be implemented
Lightweight The project team consists 1.Functional managers 2.Lead persons3.A lightweight project manager
Improved cross-functional communication through regular project team meetings
Conflicts are common and it takes a long time to resolve issues as several participants have to reach an agreement.
![Page 17: Critical decisions for ERP integration: Small business issues 資碩專一 98756011 李怡夢 98756003 顏臺良 International Journal of Information Management(2009) Management](https://reader035.vdocuments.net/reader035/viewer/2022081505/5697bff91a28abf838cbfb13/html5/thumbnails/17.jpg)
Alternative team structuresMethod Description Advantages Disadvantages
*Heavyweight A senior manager has direct authority and control over the ERP project
Straight forward communication gives a clear sense of direction.
Strategy turns increasingly difficult to use as the size and complexity of the ERP implementation increases.
A-Team This team structure is similar to heavyweight structure1.A senior manager manages the project team. 2.all the functional managers are full time members of the ERP team
The complete authority to make most of the decisions at all levels lies within the team.
As decisions can be made by the core team without the need to communicate with other team members there may be limited buy-in for these decisions
![Page 18: Critical decisions for ERP integration: Small business issues 資碩專一 98756011 李怡夢 98756003 顏臺良 International Journal of Information Management(2009) Management](https://reader035.vdocuments.net/reader035/viewer/2022081505/5697bff91a28abf838cbfb13/html5/thumbnails/18.jpg)
Implementation strategy
Seven generally deployed strategiesBreakneckStarTurnkey, Low Risk, and In-House
Not have the luxury of full time human resources to an ERP implementation
BudgetPartner
![Page 19: Critical decisions for ERP integration: Small business issues 資碩專一 98756011 李怡夢 98756003 顏臺良 International Journal of Information Management(2009) Management](https://reader035.vdocuments.net/reader035/viewer/2022081505/5697bff91a28abf838cbfb13/html5/thumbnails/19.jpg)
Implementation strategiesMethod Description Advantages Disadvantages
Breakneck Implement an ERP solution on a low budget very rapidly
The company has a quick solution if strategy works
A very high risk approach which rarely works
Star Do the right way with a senior manager in charge and dedicated team members
The implementation usually results faster and cheaper
Full time resources are needed
Turnkey Subcontract to ERP system integrators and providers all ERP implementation activities.
1.The implementation is done by experienced people. 2.No internal resources are needed
1.The configured product does not match business needs. 2.Outsiders cannot fully understand the functional specifications
In-house Use only internal resources to implement the ERP system
The strategy generates cost savings coupled with internal ownership
1.An inexperienced team requires a long time for implementation2.this turns out expensive
![Page 20: Critical decisions for ERP integration: Small business issues 資碩專一 98756011 李怡夢 98756003 顏臺良 International Journal of Information Management(2009) Management](https://reader035.vdocuments.net/reader035/viewer/2022081505/5697bff91a28abf838cbfb13/html5/thumbnails/20.jpg)
Implementation strategies(cont.)Method Description Advantages Disadvantages
Budget Focus costs cutting by limiting the scope of the ERP project and eliminating consultants
There is a perception that this approach is cheaper
A general lack of support from senior management produces lack of interest on the project by the users
Partner Use both internal and external resources. Split the responsibility of the ERP project
Partners complement the strength of the internal team and have partial ownership of the project
The implementation usually takes longer due to conflicts between the supply chain partner
Low risk Commit a high level of resources with low complexity and relax milestones to minimize
High probability of success
Implementation takes a long time
![Page 21: Critical decisions for ERP integration: Small business issues 資碩專一 98756011 李怡夢 98756003 顏臺良 International Journal of Information Management(2009) Management](https://reader035.vdocuments.net/reader035/viewer/2022081505/5697bff91a28abf838cbfb13/html5/thumbnails/21.jpg)
Selection of transition technique
Four basic transition techniquesBig bang
entails substantial riskPhasedProcess lines
Usually lack multiple process linesParallel
limited resources for small business.
![Page 22: Critical decisions for ERP integration: Small business issues 資碩專一 98756011 李怡夢 98756003 顏臺良 International Journal of Information Management(2009) Management](https://reader035.vdocuments.net/reader035/viewer/2022081505/5697bff91a28abf838cbfb13/html5/thumbnails/22.jpg)
ERP transition techniquesMethod Description Advantages Disadvantages
Big Bang new system go live at the same time the legacy system is taken offline
Costs are reduced since no interface programs are required
high failure rates are common
Phased One functional module at a time is transitioned in sequential order
1.Companies feel comfortable implementing one module at a time2.the resources needed at any given time are low
The transition takes a long time.
Parallel Both the legacy and the new ERP systems operate in parallel
Good recovery options are available if any thing goes wrong with the new system
Considerable more resources
Process line
1.in big bang fashion 2.only one process line at a time
The experience gained from doing one process line at the time benefits the next implementation
adds complexity
![Page 23: Critical decisions for ERP integration: Small business issues 資碩專一 98756011 李怡夢 98756003 顏臺良 International Journal of Information Management(2009) Management](https://reader035.vdocuments.net/reader035/viewer/2022081505/5697bff91a28abf838cbfb13/html5/thumbnails/23.jpg)
Database conversion strategyTwo basic data conversion methods
ElectronicWriting custom programsProcess is rapidVerifiable Data is difficult
ManualJudgments necessary during the conversionFamiliar with the new ERP system and develop a sense
![Page 24: Critical decisions for ERP integration: Small business issues 資碩專一 98756011 李怡夢 98756003 顏臺良 International Journal of Information Management(2009) Management](https://reader035.vdocuments.net/reader035/viewer/2022081505/5697bff91a28abf838cbfb13/html5/thumbnails/24.jpg)
Risk management strategyThree Risks
Small business locationRealities of small businessCompany’s niche and company’s management
![Page 25: Critical decisions for ERP integration: Small business issues 資碩專一 98756011 李怡夢 98756003 顏臺良 International Journal of Information Management(2009) Management](https://reader035.vdocuments.net/reader035/viewer/2022081505/5697bff91a28abf838cbfb13/html5/thumbnails/25.jpg)
Risk management strategyMinimize internal politics and resistance to change
Appointment of a heavyweight project managerAdopting a partner implementation strategy to allow the internal team to focus on strategic tasks
![Page 26: Critical decisions for ERP integration: Small business issues 資碩專一 98756011 李怡夢 98756003 顏臺良 International Journal of Information Management(2009) Management](https://reader035.vdocuments.net/reader035/viewer/2022081505/5697bff91a28abf838cbfb13/html5/thumbnails/26.jpg)
Change management strategyThe project manager, or champion, should accept and deal with the internal politics and resistance to change rather than go into denialEffective communications must be a priorityManagement should lay out the vision of the company and explain the expected benefits
![Page 27: Critical decisions for ERP integration: Small business issues 資碩專一 98756011 李怡夢 98756003 顏臺良 International Journal of Information Management(2009) Management](https://reader035.vdocuments.net/reader035/viewer/2022081505/5697bff91a28abf838cbfb13/html5/thumbnails/27.jpg)
ConclusionsDecision to install an ERP
Assigning a heavyweight project manager Partnering with an external organization with the requisite experience Implementing the ERP package in a phased manner Adopting a predominantly manual database conversion strategy Proactively managing project risk and internal change
