Paul Carver writes "Should developers be responsible for installing the software they develop into production environments? What about System Test environments? I'm not a developer and I'm not all that familiar with Agile or DevOps, but it seems unhealthy to me to have software installs done by developers. I think that properly developed software should come complete with installation instructions that can be followed by someone other than the person who wrote the code. I'd like to hear opinions from developers. Do you prefer a workplace where you hand off packaged software to other teams to deploy or do you prefer to personally install your software into System Test and then personally install it into production once the System Testers have certified it? For context, I'm talking about enterprise grade, Internet facing web services sold to end users as well as large companies on either credit card billing or contractual basis with service level agreements and 24x7 Operations support. I'm not talking about little one (wo)man shops and free or Google style years long beta services."
