CMMI is a framework for improving processes and achieving higher levels of maturity. The CMMI Institute developed it, and it provides principles and best practices for controlling and optimizing processes throughout a business. CMMI focuses on enhancing process capacity and performance, enabling businesses to provide higher-quality products and services while increasing efficiency and productivity. Sample CMMI Level 3 Documents (Dev) are globally used documents that can be easily modified and meet the clause-by-clause requirements of CMMI maturity models for software development businesses.
