The CMMI ModelsThe CMMI Product Suite currently has three models relevant toimprovement in a particular area of interest.Development (CMMI-DEV) build stuff tangible, storable products made to specification in a lifecycleAcquisition (CMMI-ACQ) buy stuff specify, solicit, select, contract, procure, accept, transition to consumerServices (CMMI-SVC) do stuff intangible, non-storable products delivered via a service system based on explicit orimplicit service requestsSome material adapted from The CMMI Crash Course, 2005-9 Entinex, Inc.Multi-Constellation/ModelAlex Stall and Eileen Forrester 2012 Carnegie Mellon University3

Patterns we see in using DEV and SVCIncreasingly, CMMI-DEV and CMMI-SVC are used in the same organization,implementing and appraising together.Choose CMMI-SVC as your base model, grab the engineering PAs forparticular services.Treat development or engineering as a service, managed using the practices ofCMMI-SVC, and treat the engineering PAs as informative material to SSD.Use all of the CMMI-DEV for advanced development, and then add CMMI-SVCfor additional practices: SCON, SST, CAM.Start with CMMI-DEV at the beginning of a life cycle, adding in a few SVC goalsand practices. Add more in mid-life. Change over to SVC at the end foroperations and maintenance.Take a life cycle view and consider total cost of ownership, may add multipleother models, do a mash up or composition from CMMI and other models.Multi-Constellation/ModelAlex Stall and Eileen Forrester 2012 Carnegie Mellon University8
SSD and CMMI-DEV Engineering PAsSome mixed services and developmentenvironments use both the engineeringPAs from DEV and a single SVC PA:Service System Development. Thepatterns: Stick with SSD, but grab a singleengineering PA when needed Use SSD for simple development, addengineering PAs for complex development Use SSD and treat engineering PAsroughly as “informative material” Use engineering PAs for service systems,but add the informative material from SSDto get the service flavorMulti-Constellation/ModelAlex Stall and Eileen Forrester 2012 Carnegie Mellon University9

What’s the Summary?CMMI-SVC has a PA that “summarizes” the engineering PAs in DEV,for those occasions when more detailed practice information is needed.CMMI-SVC and CMMI-DEV can be used and appraised together.Development or engineering tasks can be treated as a service, andmanaged with the practices in CMMI-SVC.Advanced development may use all of the CMMI-DEV, and then addCMMI-SVC for additional practices: SCON, SST, CAM.Service and development organizations can add security, resilience,and people management—and more—as needed.The SEI is positioning to support multi model implementation.Multi-Constellation/ModelAlex Stall and Eileen Forrester 2012 Carnegie Mellon University25
