The prize for the most popular retrospective of 2013 goes to … my retro in a pub where we played Jenga. Thanks to my Marmite Voting system, I am able to confirm that the most popular retrospective by far was the one where we held the retro in the local… Read More »The best retro of 2013

The Goal

“Have you read The Goal by Eli Goldratt? If not, you’re in for a treat.” This was a statement made by Chris Young at LKUK13 which, although it was said about every book he mentioned, was very true. I was in for a treat. Although it was written nearly 30 years… Read More »The Goal

This lack of externally visible, tangible deliverables sometimes makes coaches (and ScrumMasters) feel they need to have an outward show of… Read More »Too much change

When I first started looking into Kanban, I thought I understood what Lead Time, WIP and Throughput Rate meant. I discussed how to calculate them, use them and even produced a video explaining why limiting WIP makes sense referring to them. Then I got told by a bunch of experts… Read More »Kanban Terminology

Are we like chefs?

I remember an episode of Saturday Kitchen, featuring Raymond Blanc, where he refused to be drawn into the ridiculous “omelette challenge” – his sentiment was, if you don’t have  a few extra minutes to cook an omelette properly, then it’s not worth making. Blanc’s belief mirrors the menu from Restaurant… Read More »Are we like chefs?
