Albert Einstein said "A clever person solves a problem; a wise person avoids it". After reading this quote, it reminded me that project managers spend a lot of time (or should be) avoiding problems. One thing that can help project managers to avoid problems is following a defined process, or more specifically, a Project Management Methodology (PMM). At its core a PMM is a set of agreed-upon processes that assists project managers to deliver predictable project outcomes.
To create a PMM you need to define all project management processes, procedures and policies used to deliver your organization's projects. Also, don't forget to develop or obtain a set of project templates as they are an important part of any PMM. Finally, you must develop a training program to introduce and educate your organization about the new PMM.
KEY POINT - When developing a PMM ensure you must include input from your lead project managers and any other personnel that have a stake in your project management outcomes.
