Best practice for task that is obsolete but you still want record of it?

[Donald Phillips]

We are using Kanban to manage our workflow. What would be the best practice for an item that no longer needs to be completed but you want to keep record of why it became obsolete? 

Is it just best to delete it or make notes in comments and still mark it as Done?

I have used two different solutions:

• a dedicated "Cancelled" status
• a Resolution value (cancelled, won't do, etc)

Generally I prefer the latter but there are cases where the former works best.

Got it! Thanks for the feedback, Jack!
