Comparative Analysis of CMMI and ISO 9001. Framework Similarities. Framework Assumptions. Both assume “ Process†influences “ Product†Both emphasize on Continual Process Improvement Both state Management Commitment and Employee Involvement as key success factors.
E N D
Framework Assumptions Both assume “Process” influences “Product” Both emphasize on Continual Process Improvement Both state Management Commitment and Employee Involvement as key success factors Both talk about using data for decision making Both imply and require change in the organization’s cultural DNA Both promote Business Excellence
Framework Structure Both enumerate a list of requirements or practices that need to be demonstrated Both assume interdependencies and interfaces amongst the various framework components Both stress on documentary evidence as an integral footprint of framework usage
Framework Content Both describe the practices or requirements for the core function in detail (“Engineering” or “Product Realization”) Both require the formalization of organizational processes Both specify the documents and records that need to be created Both require conduct of independent assurance or audit on process implementation Both require management review of process implementation
Framework Assumptions CMMI uses “project” as the central concept – practices are purposed to enable the successful execution of the projects by the organization in a consistent manner ISO 9001 uses “organization” as the central concept – practices are purposed to enable the successful implementation of the organization’s quality management system
Framework Structure CMMI is a multi-level model (5 Maturity Levels) CMMI has its practices categorized as Process Areas CMMI further categorizes the practices as Specific and Generic ISO 9001 is a binary model (Either ISO Certified or Not) ISO 9001 has its requirements categorized as Sections ISO further categorizes the practices into Sub- Sections or Sub-Sub-Sections
Framework Structure (contd.) CMMI has its Process Areas described using the same pattern (Purpose, Specific and Generic – Goals and Practices) ISO 9001 has its Sections described in an inconsistent manner (Some Sections have Sub-section, some have Sub-sub-Sections)
Framework Content CMMI talks about all the three - Organization, Products and Projects ISO 9001 talks about Organization and Products but not about Projects
Framework Content (contd.) • CMMI either doesn’t cover explicitly or at all areas such as: • Customer Management • Prevention of “Potential” System Failures • ISO 9001 either doesn’t cover explicitly or at all areas such as: • Risk Management • Planning and Management of Projects/Programs
