for appraising current processes." Mary Beth Chrissis, Mike Konrad, and Sandy Shrum Rawdon were the authorship team for the hard copy publication of CMMI for Development Version 1.2 and 1.3. The Addison-Wesley publication of Version 1.3 was dedicated to the memory of Watts Humphry. Eileen C. Forrester, Brandon L. Buteau, and Sandy Shrum were the authorship team for the hard copy publication of CMMI for Services Version 1.3. Rawdon "Rusty" Young was the chief architect for the development of CMMI version 2.0. He was previously the CMMI Product Owner and the SCAMPI Quality Lead for the Software Engineering Institute. In March 2016, the CMMI Institute was acquired by ISACA. CMMI topics Representation In version 1.3 CMMI existed in two representations: continuous and staged. The continuous representation is designed to allow the user to focus on the specific processes that are considered important for the organization's immediate business objectives, or those to which the organization assigns a high degree of risks. The staged representation is designed to provide a standard sequence of improvements, and can serve as a basis for comparing the maturity of different projects and organizations. The staged representation also provides for an easy migration from the SW-CMM to CMMI. In version 2.0 the above representation separation was cancelled and there is now only one cohesive model. Model framework (v1.3) Depending on the areas of interest (acquisition, services, development) used, the process areas it contains will vary. Process areas are the areas that will be covered by the organization's processes. The table below lists the seventeen CMMI core process areas that are present for all CMMI areas of interest in version 1.3. Maturity levels for services The process areas below and their maturity levels are listed for the CMMI for services model: Maturity Level 2 – Managed CM – Configuration Management MA – Measurement and Analysis PPQA – Process and Quality Assurance REQM – Requirements Management SAM – Supplier Agreement Management SD – Service Delivery WMC – Work Monitoring and Control WP – Work Planning Maturity Level 3 – Defined CAM – Capacity and Availability Management DAR – Decision Analysis and Resolution IRP – Incident Resolution and Prevention IWM – Integrated Work Managements OPD – Organizational Process Definition OPF – Organizational Process Focus... OT – Organizational Training RSKM – Risk Management SCON – Service Continuity SSD – Service System Development SST – Service System Transition STSM – Strategic Service
