What is the major difference between Level 2 and Level 3 of the Capability Maturity Model?
Capability Maturity Model is a bench-mark for measuring the maturity of an organization’s software process. It is a methodology used to develop and refine an organization’s software development process. CMM can be used to assess an organization against a scale of five process maturity levels
based on certain Key Process Areas (KPA). It describes the maturity of the company based upon the project the company is dealing with and the clients. Each level ranks the organization according to its standardization of processes in the subject area being assessed. A maturity model provides:
Maturity Level 1 – Initial: Company has no standard process for software development. Nor does it have a project-tracking system that enables developers to predict costs or finish dates with any accuracy. In detail we can describe it as given below:
Maturity Level 2 – Managed: Company has installed basic software management processes and controls. But there is no consistency or coordination among different groups. In detail we can describe it as given below:
Maturity Level 3 – Defined: Company has pulled together a standard set of processes and controls for the entire organization so that developers can move between projects more easily and customers can begin to get consistency from different groups. In detail we can describe it as given below:
Maturity Level 4 – Quantitatively Managed: In addition to implementing standard processes, company has installed systems to measure the quality of those processes across all projects. In detail we can describe it as given below:
Maturity Level 5 – Optimizing: Company has accomplished all of the above and can now begin to see patterns in performance over time, so it can tweak its processes in order to improve productivity and reduce defects in software development across the entire organization. In detail we can describe it as given below:

At maturity level 2, the standards, process descriptions, and procedures may be quite different in each specific instance of the process (for example, on a particular project).
What is the difference between capability level and maturity level?Process maturity levels classify organisations according to their ability to control their various processes. Process capability levels classify the performances of (some) processes of a certain process area done by an organisation, organisational department, or project.
What are different levels of capability maturity model?The Five Levels of the Capability Maturity Model Integrated (Carnegie Mellon 1999). What is Level 3 maturity?CMMI Level 3 – An appraisal at maturity level 3 indicates an organization is performing at a “defined” level. At this level, processes are well characterized and understood and are described in standards, procedures, tools, and methods.
