The issue is not just about the software itself. The whole organization has to change along as well!

Which makes ‘installation’ complex and risky you need to handle this systematically! (have a plan)

In this pic. the strategies are ordered such that:

Change ‘management’ Address the organizational aspect of migration (the

organization has to migrate as well), covering: Revising work procedures & policies Training Assessing cost/benefit Motivating adoption of new systems

Important to realize that there are three parties here: Change sponsors within organization, have authority Change agent just the project management body, has no authority Adopters / users people that must adapt to the new system
