Where ITIL fits in ITIL forms a layer between in house procedures and the code of practice, so imagine the metaphor of a five tiered pyramid, the bottom layer of building blocks are the in house procedures, the second layer of building blocks are ITIL Best practice.
The next layer is the code of practice which ITIL helps us achieve, then comes the standard (BS15000) and finally the pinnacle is ISO. ANECDOTE –Capability Maturity Model ITIL and CMMI are distinctly different but not mutually exclusive maturity models.
The main difference between the two is that CMMI focuses on software process maturity continuous improvement whereas ITIL helps us understand and develop all of the areas within our infrastructure. ITIL and CMMI – similarities The initial Capability Maturity Model (CMM v1.0) was developed by the Software Engineering Institute and specifically addressed software process maturity.
It was first released in 1990, and after its successful adoption and usage in many areas, other CMM’s were developed for other disciplines. ITIL and CMMI – which one should I choose? The answer to that question is that there is no single reason why you cannot have both.
You see, ITIL is not prescriptive and the process maturity framework that ITIL conforms to is very similar to CMMI’s model. ITIL and CMMI – both, as a structured approach. If CMMI is a structured approach for software development then, the ITIL Release Management process dovetails into it perfectly.
Release Management focuses on the release of software into the live environment. ANECDOTE –Software Changes “I updated that document yesterday, but it’s not appearing on the Intranet.
What happened?” “The new version’s wrong! Did we back up the old one?” “Chris and I were editing the same file at the same time, but I finished first.
His changes overwrote mine! “Who made that change?”
