This is the major basis of the CMM Levels [1]. At higher levels of maturity and necessity, systems and processes are designed to increasingly prevent errors from reaching a production environment.

Amazon is taking the right approach here. The fact that a system as complex and important as S3 can be taken down is a failure of the system, not the person who took it down accidentally.

A lot of IT vendors I have worked with, they all were CMM/CMMi level 5. But the crappiness in their work development/process/deployment etc make me wonder if all their efforts go in attaining those certifications as oppose to doing something better.


As someone who worked for an IT vendor with certification and as someone who was part of the certification team at another place, I can assure you that you're right.

The certification is more for the organization/unit and the people working do not realize what they are for. Another thing that usually becomes a problem is the rigidity of the certification. Saying you need X, Y and Z documented is easy, but it doesn't work for projects that maybe don't have Y. So people make up documentation and process just to be compliant, this soon becomes a hinderance to the work. At this point people either abandon the process or follow it and the work suffers.


Thank you for adding this comment. I am glad there are more people out there that aren't afraid to be honest about some of the nonsense 'follow the process no matter what' stuff that I have experienced over the years.


CMM level 5 ==> You have a well-documented, repeatable, and still horrible process that declares all errors statistically uncommon by "augmenting" the root cause with random factors. Insta-certification.

(I lied about the "insta" part)
