=== Capability Maturity Model Integration ===
The CMMI model's application in software development has sometimes been problematic. Applying multiple models that are not integrated within and across an organization could be costly in training, appraisals, and improvement activities. The [[Capability Maturity Model Integration]] (CMMI) project was formed to sort out the problem of using multiple models for software development processes, thus the CMMI model has superseded the CMM model, though the CMM model continues to be a general theoretical process capability model used in the public domain.<ref>{{Cite book|url=https://books.google.com/books?id=NJ0Apk1iNDAC&q=The+Capability+Maturity+Model+Integration+%28CMMI%29+project+was+formed+to+sort+out+the+problem+of+using+multiple+models+for+software+development+processes%2C+thus+the+CMMI+model+has+superseded+the+CMM+model%2C+though+the+CMM+model+continues+to+be+a+general+theoretical+process+capability+model+used+in+the+public+domain&pg=PA486|title=Juran'S Quality Hb 6E|last=Juran|date=2010-08-26|publisher=McGraw-Hill Education (India) Pvt Limited|isbn=9780071070898|language=en}}</ref>{{Citation needed|date=March 2012}}<ref>{{Cite book|title=Proceedings of the International Conference on Transformations in Engineering Education|last=Natarajan|first=R|publisher=Springer|year=2015}}</ref>

In 2016, the responsibility for CMMI was transferred to the Information Systems Audit and Control Association (ISACA).  ISACA subsequently released CMMI v2.0 in 2021. It was upgraded again to CMMI v3.0 in 2023.  CMMI now places a greater emphasis on the process architecture which is typically realized as a process diagram. Copies of CMMI are available now only by subscription.
