The organization needs to devise a method to assign resources, schedule the work, decompose activities to a manageable size , trace requirements and contractual obligations, and measure success. We suggest that individuals be given certain roles to play to carry out these assignments. We suggest that a sponsor designate a champion, and that an EPG Lead be appointed to work with personnel from the organization to establish the process improvement infrastructure. The CMMI is tremendously interconnected . Your organization will want to know how everything fits together. Do not attempt to flowchart the CMMI. This exercise goes in one ear and out the other because people have little experience with the CMMI and cannot equate it with anything relevant to them.
Try to do most of what the CMMI suggests. If it does not fit, document why and devise an alternative practice. Tailor your approach to your organization. For example, when writing procedures, DoD likes books; commercial organizations do not. Keep it simple and to the point.
Process improvement is continuous. Once you start, you will uncover more and more areas to be improved and issues to be resolved.
