All work finishes, eventually. (We hope...) When a board gets done, you can move it to your account's Archive by selecting it, and then using the Board Actions menu like this:
Boards in the Archive are frozen in every respect:
It's easier to meet Freedom of Information Act requests: if you are working any US government agency – at the Federal, State, or Local level – you will be subject to various public disclosure requirements, and Archived Boards help you with just that!
Because an Archived Board is frozen, you can be sure that you are presenting the true facts about a board that was completed using Kerika – intact, unchanged and complete!
In fact, Archiving when combined with the exporting feature built into all Task Boards and Scrum Boards makes Kerika really helpful in dealing with public disclosure requests: instead of wading through a mountain of paper, you can meet your FOIA requests with just a couple of mouse clicks!
Of course, that Backlog will probably have changed since you archived the Scrum Board, since other Scrum Boards – used for successive Sprints or by parallel teams – will have taken up some of the cards from the Backlog, so Kerika shows the current state of the Backlog when you view an archived Scrum Board.
This makes it really easy to go back to old Sprints, each of which you captured as an archived Scrum Board, and see how work got done over a course of many months!
