Information dimensions
Our recommendation is not to jump immediately into creating a Kanban board that looks just like the ones you have seen somewhere else. If so, all the work done last week will be wasted. Instead, take the results from your workshops and write down a list of things you think will be important to visualize and have easy access to. Let's call them "information dimensions". Examples of information dimensions are as follows:
Status
Priority
Classes of service
What to do
Who's working on it
Customer/origin
Request owner
When is it expected to be done
Estimated size
Test environment
What information should be shown is very context-dependent. Please take some time to figure out what kind of information is important to visualize for you.
