..it's one thing to debate whether the task-based and system-based
perspectives should be the same. It's another thing entirely to claim that there's no distinction between how a user approaches an application and how a developer designs it.

Tony Markatos responds:

Properly utilizing Structured Systems Analysis and Design (SSAD) - the most prevalent of the formal analysis/design techniques - requires that the developer "approach" the application the same way that the end-user does. When a developer does not do such, the whole formal analysis/design effort falls apart - often very quickly and very completely. This happens frequently - like real frequently. The result is the poor designs that we (TW's) so often have to document.

Bill Burns said:

I find it rather reductionist in terms of practice (as opposed to the ideal world that academics keep fathoming) to claim that the legitimate software development world follows this strict set of
principals

Tony Markatos responds:

Most do not follow "this strict set of principles". This is no surprise to anyone with any experience in the software industry. But, taking a rigorous user-centered approach to analysis the foundation of good design. And many have had great success with end-user focused development tools like SSAD - including myself.
