Radiate Everything
Have you ever walked into a room housing a high-performing team and found that it just feels different? It's hard to capture why it feels different in text, but you just get a sensation of cohesion and openness all at the same time. You may see sticky notes on a wall showing things being worked on or tracking tools such as a burndown chart visible to all who enter showing the team's progress so far. Possibly you see things such as build monitors showing dashboards of code being built and deployed or tests executing, or even live stats of the applications' and platform's current usage!
All of these things are information radiators, and they are probably one of the most important things we have in our kit bags.
An information radiator serves one purpose – to show whoever passes by the latest information. Radiate all the things, from test scores to retrospectives, architecture diagrams, and even things that could hurt the team! Be proud...
