CMM vs. CMMI: Know the Difference
By Shumaila Saeed || Published on February 4, 2024
CMM (Capability Maturity Model) focuses on software development process improvement, while CMMI (Capability Maturity Model Integration) integrates multiple process models.
Key Differences
CMM, developed by SEI, provides a framework for software process improvement. CMMI, an evolution of CMM, integrates various models for process improvement across different areas.
