The New Agile–Why Is Agile So Popular?

agile-logo

Is it the cool name? Is it the actual successes? Is it the drawings with lots of loops in them? Might be all, but above all else, there are the perceived (and maybe the not actual) value of agile, that organizations want.

Last month I was in Huib Schoots’ workshop. He talked about being asked “What’s the ROI of testing?”. To which he replied “I don’t know, what’s the ROI of management?”. We are really obsessed with ROI, aren’t we? We use it a lot as a tool for decision making, but are we using it wisely? ROI (Return On Investment) is ...

software-development-2-logo

Why do we keep trying to attain control? We don’t like uncertainty, and control over a piece of reality relaxes us. A controlled environment is good for our health.
