In level one of the maturity model, the processes are ad hoc and chaotic. The project is completed and results are obtained but the success is not repeatable since much is attributed to the skills of the resources involved. Also often the project exceeds limits of time and budget and critical processes are overlooked to get the work done. To move from this level to the next, definite practices need to be put in place and the company should only accept projects that can be executed within its infrastructure. In level two, some project management practices are in place and hence the results are repeatable. Also processes are adhered to even when time is critical and results are documented for future use. Process discipline and project specific standards helps in this level, but to move on to the next level, organization-wide fixed standards are essential, and they allow for project specific versions as a deviation. Requirement Management, Project Planning, Tracking and Oversight, Quality Assurance and Configuration Management are introduced at a project specific level.In maturity level three, the process is now tailored for every aspect of the project. The measuring tools, standards and methodology are in place and the management has knowledge of the project status at all times. The key feature is that there is consistency in the processes and project quality is assured. To move on to the next level, statistical analysis will go a long way to predict performances accurately. Level 2 Quality management and processes are defined and managed at an organization level instead of at a project level.
PMMM Level 4 Managed
In maturity level four, the measurements of the project management processes are very well defined and precise: statistical techniques are employed for even the sub processes as they are considered to impact the overall performance. The processes are maintained even when modifications are needed due to project uniqueness. The projects can now be quantitatively predicted as compared to the qualitative predictions in level three. Software Quality Management and Quality Process Management are introduced at this level.
PMMM Level 5 Optimized
In maturity level five, continuous self-improvement processes are
