I have been asked to estimate the number of full time resources required by my company to facilitate its drive to Maturity Level 3 PM, SYS, SW, HW and ACQ. Is there any documentation or published information that will help in putting together a robust estimate of resources required?
First and foremost the driving factor for estimating the number of full time resources needed to implement the CMMI is the size of the organization. Over time we have seen that it takes 3 – 5% of the organization to perform PPQA, 3- 5 % of the organization to perform CM, and 3 – 5% of the organization to perform the necessary CMMI implementation activities.
So, if your organization is about 20 – 30 people, then you may only need one full time resource. However, if your organization is about 100 people, then you may need 3 to 5 full time resources.
Other factors contributing to this estimate is how strong a ML 2 foundation is already in place and how much of what you currently have in place is at ML 3. Documenting the processes and procedures is the easy part, and it can be done by a small core group. The larger task is deploying the new processes and process assets and having people use them to change how they approach their jobs.
