ERP IMPLEMENTATION & LIFE CYCLE

RELATION B/W MIS & ERP

Erp life cycleERP implementation lifecycle focus on the ERP project which is carried out to make ERP up and running.ERP project is likely to go through different phases like any other project.Most often these phases do not necessarily depend on one another in a sequence, i.e. one phase might start before previous phase has finished

The different phases of ERP implementation arePre-evaluation ScreeningPackage EvaluationProject Planning PhaseGap-AnalysisReengineeringConfiguration

Pre-evaluation ScreeningWhen the company has decided to implement the ERP the search for the convenient and suitable ERP package begins.

The objective of this phase is to find the package that is flexible enough to meet the companys need or in other words, a software that could be customised to obtain a good fit.Once the packages to be evaluated are identified, the company needs to develop a selection criteria that will permit the evaluation of all the available packages on the same scalePackage Evaluation

Package EvaluationFlexibility and scalabilityComplexityUser friendlinessQuick implementation

It is better to have a selection committee that will do the evaluation process.

Project Planning PhaseThis is the phase that designs the implementation process. Time schedules, deadlines, etc. for the project are arrived at.The project plan is developed in this phase.In this phase the details of how to go about the implementation are decided. The project plan is developed, roles are identified and responsibilities are assigned.

Contd..The organizational resources that will be used for the implementation are decided and the people who are supposed to head the implementation are identified.The implementation team members are selected and task allocation is done.The phase will decide when to begin the project, how to do it and when the project is supposed to be completed.

Contd..The phase will also plan the What to do in case of contingencies; how to monitor the progress of the implementation; The phase will plan what control measures should be installed and what corrective actions should be taken when things get out of control.The project planning is usually done by a committee constituted by the team leaders of each implementation group headed by CIO.

Gap AnalysisThis is the most crucial phase for the success of the ERP implementation.Simply it is the process through which companies create a complete model of where they are now, and in which direction they want to head in the future.The trick is to design a model which both anticipates and covers any functional gaps

Contd..Some companies decide to live without a particular function. Other solutions include:UpgradeIdentify the third party product that might fill the gapDesign a custom programAltering the ERP source code, (the most expensive alternative; usually reserved for mission-critical installation)

reengineeringThe second use of of the word reengineering in the ERP field focus on the Business Process Reengineering (BPR)The BPR approach to an ERP implementation implies that there are two separate, but closely linked implementations on an ERP siteTechnical ImplementationBusiness Process Implementation

Contd..The BPR approach emphasises the human element of necessary change within organisations.

This approach is more time consuming and has received a lot of criticism for creating a big budget and extended projects.

But those who support it argue that you cannot ignore human element.

configurationInstead a prototype (a simulation of the actual business processes of the company) will be used.

The prototype allows for thorough testing of the to be model in a controlled environment.

Configuring the system reveals both the strength and the weaknesses of the company business processes.

Implementation & testingSynchronously when the configuration is taking place, the implementation team is being trained.

This is the phase where the company trains its employees to implement and later, run the system.

testingThis is the point where you are testing a real case scenarios.

The test cases must be designed to specifically to find the weak links in the system and these bugs should be fixed before going live.

Going LiveThis is the phase where all technicalities are over, and the system is officially declared operational.

In this phase all data conversion must have been done, and databases are up and running; and the prototype is fully configured and tested.

Going LiveThe implementation team must have tested and run the system successfully for some time.

Once the system is live the old system is removed and the new system is used for doing business.

End-User TrainingThis is the phase where the actual users of the system will be trained on how to use the system.

The employees who are going to use the new system are identified and their skills are noted.

Based on their skill levels are divided into groups.

End-User TrainingThen each group is given training on the new system.This training is very useful as the success of the ERP system is in the hands of end-users.

The end-user training is much more important and much more difficult than implementation team training since people are always reluctant to change.

End-User TrainingYou can have the best technology in the world, but if you dont have a community who wants to use it and who are excited about it, then it has no purpose. Chris Hughes Co-Founder of FaceBook.

Post Implementation (Maintenance Mode)This is the very critical phase when the implementation phase is over.

There must be enough employees who are trained to handle the problem that might occurred when the system is running.

There must be technical people in the company who have the ability to enhance the system when required.

Post Implementation (Maintenance Mode)Living with ERP systems will be different from installing them.Projects for implementing the ERP sysstems get a lot of resources and attention.

However an organisation can only get the maximum value of these inputs if it successfully adopts and effectively uses the system.

ERP METHODOLOGYTHE BIG BANG The Big bang approach promised to reduce the integration costin the condition of thorough and careful execution. This method dominated early ERP implementations; it partiallycontributed to the higher rate of failure of ERP implementation. This type implementation of a large scale information system,which typically follows SDLC.

Modular implementationIn this method focus one ERP module at a time. This limits the scope ofimplementation usually to one functional department.

This approach suits companies the do not share many common process acrossdepartment or business unit.

Modular implementation reduces the risk of installation, customization andoperation of ERP system by reducing the scope of the implementation.

The successful implementation of one module can benefit the over all successof an ERP project.

Process orientated implementationSupport one or few critical business processes,Which involve a few business units.In this limited to functionality closely related tothe intended business process.Eventually grow into a full blown implementation of the ERP system.This approach is utilized by many small to mid-sizedcompanies which tend to have less complex internalbusiness process.
