CMMI works well with Lean, RUP, and architecture-centric engineering. It can also be part of a program that uses three or more methods, standards, and technologies.

CMMI and Lean

Lean Thinking with CMMI, a presentation from SEPG North America 2009 by Christian Hertneck, describes the synergy between CMMI and Lean.

Lean CMMI-Based Process Improvement, a presentation from SEPG Europe 2011 by Teodora Bozheva of Tecnalia Research and Innovation, shares results of a study that piloted the use of Lean tools with CMMI-DEV.

CMMI and RUP

Fast Track to CMMI Implementation: Integrating the CMMI and RUP Process Frameworks, an article published on the IBM website, explains why and how to integrate the use of CMMI.

SCRUMP (Scrum + RUP) and CMMI: The Story of a Harmonious Process and Product Deployment, a presentation from SEPG North America 2011 by Jennifer Turgeon of Sandia National Laboratories, describes a case study that combined the use of Scrum, RUP, and CMMI, including results, lessons learned, and recommendations.

CMMI and Architecture-Centric Engineering

CMMI V1.3 and Architecture-Centric Engineering is a webinar that explains the basics of architecture-centric engineering and how these concepts have been incorporated into CMMI for Development.

CMMI and Multiple Approaches

Extreme Programming, Six Sigma, CMMI: How They Can Work Together—A JP Morgan Chase Case Study, a presentation from SEPG North America 2005 by Bob Jarvis and Stephen Gristock of JPMorgan, describes how JPMorgan used these three technologies together to reduce defects, project effort, and project duration.

Process Improvement Essentials: CMMI, Six Sigma, and ISO 9001, a book from James Persse, describes how these three process improvement technologies can help your organization improve by weighing the advantages of each for specific issues.

Implementation of PMBOK Along With CMMI: QCG Experience, a presentation by Sharma Sriram and Bansi Mohan Rath of Wipro Technologies, provides an overview of the Project Management Body of Knowledge (PMBOK) and its interactions with CMMI.

SCRUMP (Scrum + RUP) and CMMI: The Story of a Harmonious Process and Product Deployment, a presentation from SEPG North America 2011 by Jennifer Turgeon of Sandia National Laboratories, describes a case study that combined the use of Scrum, RUP, and CMMI, including results, lessons learned, and recommendations.

CMMI, ITIL & ISO 20000: A Mutually Supportive Relationship, a presentation from SEPG Europe 2009 by Kieran Doyle of Lamri, describes the interrelationships among these three technologies.

There are other methods, standards, and technologies that comprise CMMI Compatibility.
