A

Answer to Question 2

The traditional ERP life cycle begins with the scope and commitment stage. Besides doing the feasibility study, in this stage the scope of the ERP application in the enterprise is determined. The project team is set up also at this time. In the analysis and design stage the project team does a gap analysis and also chooses the ERP vendor and any consultants. This leads to the acquisition and development stage. Based on the gap analysis the software is configured and the hardware is set up. Any necessary data must be migrated over to the new system also. This leads to the implementation stage when the new system is released to the users in a predefined conversion strategy. When the resulting system is handed over to the IT personnel, this is the final stage called the operation stage.
