The ticket (likely a proposal) was accepted with the documented changes (in the ticket description/comments). As a result a series of new tickets should be created and this ticket closed.

Items that are still open, but nobody plans to work on them in the near future. These tickets should be considered during sprint planning.

When a task cannot be worked on due to something blocking it. Ideally this is commented in the ticket.

Tickets currently being worked on

A ticket that requires work with hardware. This would indicate that it requires physical presence, so should not be allocated to somebody away from the field.

A ticket for a meeting. Ideally this ticket should also have an agenda to keep discussions focussed.

A proposal for some work that requires team discussion

This work needs some attention soon
