My opinion for key performance indicators of a successful PMI are as follows:
1) Plan for PMI prior to due diligence and focus on the key areas during the due diligence process
2) Clear lines of communication to all stakeholders in a timely manner
3) Effective and efficient project management
4) Employees retention
5) Address and manage cultural differences
6) Adopt the “Best of both” approach for best practices
7) Speed
