Since January this year I've been working on a few projects with a team of over 5 people and high-demanding standards. This raised the problem of project managing and a completely different view of the web development cycle. In this article I'd like to outline the major steps of the software development cycle and how they could be applied to the web development business.

Along with the main three categories (dev, test and production) he also gets a bit more fine grained with things like:

• Development: Pre-alpha Stage
• Development: Beta Stage
• Testing: Release Candidate
• Production: General Availability

When I have done training for Zend Framework, one of the things that mystifies students to some extent is the whole plugin architecture and where things can go. There has been several articles written about it, but they tend to use code to describe it. [...] I had found that when I drew out the request lifecycle that it helped the students understand it better.

His diagram (seen here) lays out the full execution relationship for the request structure including where plugins, action helpers and controllers fit in the mix. He also describes it in more detail, mentioning some of the variations that could happen along the way.
