PMBOK has defined 42 management processes. Yet, not all the processes are relevant or some are less important according to the organization's size. I am doing a survey which objective in mind is to identify which process is important for Small Medium Enterprise in performing software project. I believe that there are too many processes in the PMBOK that SMEs need to adopt. In your opinion which processes are important for SMEs?
In my opinion, it is a mistake to try to identify what processes would be important for any type of project or business, no matter the attribute, through a survey like this. You stand up and deploy those processes that you need. And the need is dictated by what you are producing.
Work right to left instead of left to right. What are you producing? What do you need to produce in order to produce what you are producing? Once you identify the outputs, then choose the processes you need to develop them, then identify the inputs you need.
Every project is unique. One process would be terribly important on one project, then completely irrelevant another.
