Good SCM, easy testing APIs/harnesses and easy deployment are so wildly important, it infuriates me to work at one of the the biggest names in tech and waste HOURS a day on bullshit deployment issues or copy/pasting things in six different places before I can execute my tests or do manual verification. For one project, deployment to production takes 3+ weeks, testing environments can take a week and is fraught with steps that take hours and literally can fail for any random reason and can only be mitigated by starting over. And then I come home to my side projects that can be built with a single standard command that is more or less an industry standard. I can deploy it reliably every. single. time. I have a test framework that can be run from within my development environment or from the command line with the same tool as the build tool.
