Let us look at some of the vocabulary in CMMI® that many people find difficult to relate to, especially in the early stages of their trying to understand the model. Others (like me) have got so used to the terms that we do not pause to examine basic things in the model.
Please do add your experiences as comments. And maybe we can initiate a class action change request 😉
CMMI® Expanded. That is the first place where they are curious about some terms and are puzzled about them.
Integration – ‘The term integration can be used for an activity or a project. Should it not be CMM Integrated instead of Integration?’
Integration – ‘Why is it called integration/integrated? We have seen 3 variations, viz. – SVC, ACQ and DEV, with staged and continuous. And then there is the People CMM®. Looks disintegrated to me. Definitely not integrated, no sir.’
Capability, Maturity – ‘Why have both the terms? Will the model make the capability more mature? If the model is making the process more capable and / or mature, why not call it Process Capability/ Maturity Model?’
Model(s) after CMMI®. The word model(s) is often used after the word CMMI®. ‘What does CMMI® Models mean? Capability Maturity Model Integration Models? Sounds wrong to me.’
Institutionalization. ‘Why have such a tongue twister? Can we not use something simpler?’ [Digression: Legend has it that one LA required all ATMs to be able to pronounce the word correctly to qualify as an ATM :-). End of Digression].
Managed process versus Defined process. Some CMMI® experts take great pride in being able to truly understand the difference between the two terms in the CMMI® context (if you try using the nuanced difference in normal life, you will probably get institutionalized :-)). And it really gets hairy when we go “a defined process is a managed process that is …….”
Peer (as in Peer Review). ‘Peer? Is that not someone in the House of Lords in Britain? Why should my work be reviewed by them? Would they be really interested?’ OR ‘I thought peer review was something done for scholarly articles and PhD thesis. My work does not qualify for that’.
Configuration Management. A frightening/ nightmarish term for many folks in the service industry like retail, insurance, transportation, etc. (they are comfortable once you explain the concept, but the term is alien).
Continuous – Here is a reaction from a statistician – ‘Is it really continuous? Each process can be in 5 states (not assessed, CL0, 1, 2, or 3). There are 24 PAs. That makes it a finite set of combinations. So it is discrete data. For a model that emphasizes on the correct use of statistics, the term continuous is very loosely used….’
