What is ERP Implementation Life Cycle?

ERP implementation life cycle can be described as different highlights or phases that are taken place during the ERP solution to fulfill the requirement of the client organization. ERP Vendor widely focuses on the life cycle of ERP implementation to deliver ERP solutions to its client organization. This life cycle is commonly used by ERP vendors around the world when the implementation of ERP solutions to client organizations.

The ERP implementation life cycle consists of 9 stages

  1. Pre Evaluation screening
  2. Package Evaluation
  3. Project Planning
  4. Gap Analysis
  5. Reengineering
  6. ERP User Training
  7. Testing
  8. Go live
  9. Post-implementation phase

Pre Evaluation screening

After ERP vendor receive “Request for proposal” they will create a project proposal with including information of ERP solution that they can deliver to the Client this stage the client organization will sent their “Request for proposal ” for vendors and out of them they will keep best for further consideration and eliminate others.

Package Evaluation

In At this stage, client organizations will deeply evaluate the best project proposals to select the best proposal that fits them. This the very critical of the stage for the client organization, because out of one error or weakness can deliver huge tangible losses as well as the intangible losses. The evaluation of the committee should be the focus on coordination of all departments, end-users, and top management as well as the external parties when selecting the best solution for their organization. After the client organization selected their solution at the end of this stage ERP vendor will inform.

Project Planning

Once a client organization select solution of ERP Vendor, they will officially start working on the ERP implementation process. In this stage, they have to understand about milestones and what are the resources that are required for implementation.after that they assign who are persons and their responsibilities for representing each milestone and they assign a deadline for each milestone .risk identification and taken place to mitigate those risks will be taken under this stage.

Gap Analysis

At this stage, ERP vendor is compering As-Is system with the To-Besystem to understand the gap between them. both client organization and ERP vendor should completely participate in this stage to identify the future enhancements and improvements that the client organization will in the future. Communication is very important is essential to discuss weakness, issues in as-is system and eliminate those in the to-be system.


Reengineering is the process of fundamental rethinking and radical redesigning of the processes. Implementation of ERP will be affected by all employees and their job roles and responsibilities. After implementation new job roles and responsibilities should be assigning to employees and new processes should be integrated with a new system. Employee resistance can be occurring in this stage due to change their traditional job roles.

ERP User Training

After ERP Vendor implemented its ERP solution in a client organization they will hold training sessions to employees. This will give a clear picture to Employees how to use the new system correctly.  They use audio-video, screenshots and handouts to provide effective programs to employees. They will take different training programs to a different level of employees in the organization to understand how to deal with new ERP with different business processes. They also use “train the trainee” method in this stage.


In this stage, the system will be tested to identify bugs and errors before the go-live stage. System developers will try to identify the system’s errors by logging multiple users at the same time entering invalid data to the system and also them trying to hack the system in different ways to find security holes. This stage is very important to ERP vendors before going live.

Go live

The new ERP solution will live in the client organization and all business processes will record by using the new system. In this stage, client organization can use different kind of strategies like big-bang, phased, parallel, process line and hybrid.

Post-implementation phase

This phase is mainly focused on maintenance of the system and upgrading the system when new features and the new version available to implement. And also this stage focuses on further user training processes. End users who are trained enough to handle the problem occurring due to the process come up with tome to time. The service level of agreement with ERP Vendor comes in to play in this stage of the ERP life cycle.
