We need to talk about testing

19 mins

Or how programmers and testers can work together for a happy and fulfilling life.

In praise of SWARMing

Most of my work these days is helping organisations figure out how to be more effective, in terms of how quickly they can identify and respond to the needs of their external and internal customers, and how well their response meets those needs.

Modern Scrum is a certification-laden minefield of detailed practises and roles.

The original interview is on their blog.] What was your first job in the industry? ¶My first job was playing Star Wars for a living. True story!

“Where should I start?”

“Is this or that practise considered part of BDD?”

“What are the mandatory ”core“ practises of BDD?”

These and similar questions were the topic of the closing panel at the recent CukeUp conference in London.

Six Impossible Things

I’m having fun in the most unlikely of places. I’m currently working at a Big American Bank. In fact, it’s so big it’s called Bank of America. I recently wrote an article for their internal agile magazine which probably best describes why I think it’s so much fun, and which I’ve reproduced below.

Blink Estimation

Experienced delivery folks can have surprisingly good instincts for macro-level estimation, as long as we are careful to manage blind spots and cognitive biases. This can be an important tool in early project investment discussions, and can remove roadblocks where people are uncomfortable or unwilling to provide estimates.
