The Capability Maturity Model Integration (CMMI) is a development model designed in part with the U.S. Department of Defense to help objectively assess government contractors’ development processes. It helps measure the maturity of development processes in a business using a scale of one to five. Processes are measured against requirements in the CMMI, which helps guide organizations through each level as they establish formal, measurable and reliable software development process.
When a business reaches the final stage of CMMI maturity, it is in a state of constant optimization of established development processes. The CMMI framework is designed to help organizations reach this level of maturity by smoothly guiding process development, implementation and maintenance. The lower levels of CMMI maturity build a strong foundation for maintaining the highest level of optimization. Every process starts out in the initial phase and evolves gradually into the final maturity level, using the CMMI as a guide for best practices.
