-The '''Capability Maturity Model (CMM)''' is a development model created after study of [[data]] collected from organizations that contracted with the U.S. Department of Defense, who funded the research. In the 1980s, several US military projects involving software subcontractors ran over-budget and were completed far later than planned, if at all. In an effort to determine why this was occurring, the United States Air Force funded a study at the Software Engineering Institute (SEI).

 The first application of a staged maturity model to IT was not by CMU/SEI, but rather by Richard L. Nolan, who, in 1973 published the stages of growth model for IT organizations. Watts Humphrey began developing his process maturity concepts during the later stages of his 27-year career at IBM

 The Capability Maturity Model does come with some drawbacks.
-*One of which is that when organizations use CMM, they look at each level as a [[target]]. They make their goal to reach the next level up. This can be a dangerous thought because if you become fixated on reaching the next level, you begin to lose perspective and forget that the real goal is to actually improve the processes.

This can be a dangerous thought because if you become fixated on reaching the next level, you begin to lose perspective and forget that the real goal is to actually improve the processes.
 *Similarly the CMM does not specify a particular way of achieving those goals. In order to achieve them one needs to think in a flexible way. The goals will only be achieved if the organizations processes are taken into account, as each organization is different so the steps needed for process improvement will be different. Just because one organization follows the rules set by the CMM it does not guarantee that it will be successful as there are other factors involved.
 *Another disadvantage is that CMM only helps if it is put into place early in the software development process. For example, if there is a process that is in a crisis then CMM will not help overnight. It cannot be used as an emergency method of recovering from a difficult position.

 The CMM was originally intended as a tool to evaluate the ability of government contractors to perform a contracted software project. Though it comes from the area of software development, it can be, has been, and continues to be widely applied as a general model of the maturity of process (e.g., [[IT_Service_Management_(ITSM)|IT service management]] processes) in IS/IT (and other) organizations.
