Companies embarking on an ERP system implementation have to put in place a change management and control process.
You can have the best implementers and software in the world but without a clear change control and management program to ensure that the objectives over the course of the project are addressed internally your project will become another negative statistic.
What is Change control management and what aspects need to be addressed?
Control of initial program objectives with revisions
Control of new requirements and scope creep
Management of employees to negate resistance to change
One team approach management with clear goals to push towards the objective
Active management of internal resources to "own" their areas from requirements to delivery
Addressing these aspects will give your project an additional boost on the path to a successful implementation.
