ISO vs. CMMI: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on February 14, 2024
ISO (International Organization for Standardization) sets global standards for various industries, while CMMI (Capability Maturity Model Integration) is a framework for improving process efficiency in organizations, particularly in software development.
Key Differences
ISO provides a wide range of standards covering various aspects of technology, manufacturing, and service sectors. CMMI focuses specifically on software development, service delivery, and organizational processes, aiming to enhance process efficiency and quality.
ISO, an international body, develops and publishes standards for a broad spectrum of activities and industries. CMMI, developed by the Software Engineering Institute at Carnegie Mellon University, is more focused on software engineering and related business processes.
ISO certification implies that an organization complies with a specific ISO standard. CMMI appraisal involves an assessment of the organization's processes against the CMMI model's maturity levels.
ISO standards are implemented widely across different industries worldwide. CMMI is mainly used by software development companies and IT service providers to assess and improve their processes.
ISO standards are globally recognized and accepted across various industries and countries. CMMI, while internationally recognized, is particularly prevalent in the IT and software development sectors.
