In this lesson we explore ISO 9000 and CMMi quality systems.
ISO vs CMMi
Differences
- CMM emphasizes continuous process improvement whereas ISO 9001 addresses the minimum criteria for an acceptable quality system.
- CMM focuses strictly on software while ISO 9001 focuses on hardware, software, processed materials, and services.
Similarities
- The fundamental premise of ISO 9001 is that every important process should be documented. ISO 9001 requires documentation that contains the instructions or guidance on what should be done or how it should be done.
- Whereas CMM shares this emphasis on processes that are documented and practiced as documented.
- The CMM also emphasizes the need to recover information for later use in the process and for improvement of the process. This is equivalent to the quality records of ISO 9001 that document whether or not the required quality is achieved and whether or not the quality system operates effectively.
