Tom DeMarco made software analysis and development inherently safer in 1978 when he published his classic, Structured Analysis and System Specification.

These days, thanks to Lean Startup and Lean UX, I'm fairly obsessed with the idea of faking things.

So I was extremely impressed the other day with […]
