Software factories

In the real world, most of us are not quite there, but it’s now possible with only free tools to have a reliable product release process which consists of just developing and committing code. In the case of an editor releasing a versioned software product, or for a site where new features are released gradually or via AB testing, or in all cases where human testers and/or management approval are necessary, there would also have to be the click of a button to approve a release. I’m speaking in broad, hand-waving generality, but such a process, when achieved, can provide a competitive advantage to a product or site by reducing time-to-market for new features and reducing the risk of quality issues (translation: easier to develop faster with fewer bugs).

Of course setting up such a process requires a lot of up-front work, considerable expertise, and occasional maintenance down the road, and such a system will (by design, normally) come to a halt very quickly if it is fed anything other than clean, well-tested code.

This notion has been called a “software factory” or “continuous delivery” or “continuous deployment” system.

I’ll have more to say on this subject soon, but today I will just point you to a couple of interesting diagrams:
