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.

- geodel 10y agoA 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.
- vaishaksuresh 10y agoAs 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.
- _ao789 10y agoThank 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.
- groby_b 10y agoCMM 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)
