Courage
• Without knowing about a problem you cannot fix the problem
• Admitting to a mistake or problem takes courage because “Hierarchies don’t like bad news” Seddon
• Courage is a value that underpins both Scrum and XP
• It takes courage to create a good information radiator

Information Radiator
Alistair Cockburn - Agile Software Development 2nd edition- 2007
"An information radiator displays information in a place where passers by can see it. With information radiators, the passers by don't need to ask any question; the information simply hits them as they pass."
![Page 7: Information radiators](https://reader037.vdocuments.site/reader037/viewer/2022102717/558a1d56d8b42a01188b45f7/html5/thumbnails/7.jpg)
OK, but so what?
![Page 8: Information radiators](https://reader037.vdocuments.site/reader037/viewer/2022102717/558a1d56d8b42a01188b45f7/html5/thumbnails/8.jpg)
Why Bother with this?
• Information is hard to see, and all we have to work with in software development is information
• Looking for information on delivery is wasteful – Requires extra processes– People have to wait– Increases time to react– Information loses value with time
• Would your customer pay for a status report?
![Page 9: Information radiators](https://reader037.vdocuments.site/reader037/viewer/2022102717/558a1d56d8b42a01188b45f7/html5/thumbnails/9.jpg)
What do we get out of this?
Information radiators can:• Help a team self-organise• Protect a team by broadcasting the
state of delivery – no surprises• Assist with organisation and planning• Call attention to what is going on
with the work• Control / highlight WIP

OK I want to jump in. How do I do this?

Focus on the work
• What do you have to do?• What is getting in the way?• How long is it taking to get
something done?• Is there uncertainty?
• Take a system view of what is happening
![Page 12: Information radiators](https://reader037.vdocuments.site/reader037/viewer/2022102717/558a1d56d8b42a01188b45f7/html5/thumbnails/12.jpg)
Horror

KISS
• Keep It Simple, Stupid
• Easily changed and maintainable• Do it by hand, not with a tool (unless it’s
Mingle)
![Page 14: Information radiators](https://reader037.vdocuments.site/reader037/viewer/2022102717/558a1d56d8b42a01188b45f7/html5/thumbnails/14.jpg)
Simple

Predictive & Reflective
• Predictive – gives you the chance to do something different to avoid problems
• Reflective – shows if anything has changed

Change as work changes
• As you learn how learn more you should be adapting how you are working
• As you change how you work the way you present what is happening should change
• Unlike a status report; there is not a template you use and stick with

Make it big
• The information must be easily seen and understood
• Use colour and form• People can move closes for details

Make it everyone’s
