What information should be stored on Kanban Cards? I am curious to the information and level of detail that people are storing on Kanban cards? Or beter yet some templates of how they are put together. For reference here is a description of a Kanban Card <

Why not apply Kaizen to your Kanban cards?

Start with the smallest thing that gives you value - probably a title, so you can identify what the card represents. Get feedback from the team about the next most important thing that's missing. Add that.

Repeat. Stop when adding information would no longer be an improvement. The team should feel comfortable with suggesting the removal of information when it's no longer needed, too.

You may also want to include the input of other stakeholders, if they use your board for status, etc.
