Recommended practice of Github issue management

  • When a new proposal (issue) is created, the issue is generally assigned to the person who makes the proposal and put in "submitted" status.
  • Once the team agrees to the general approach and decides to go to validation status, chair moves the issue to "in validation" status and the Secretariat creates a branch. If further discussion is necessary, the issue is moved to "in discussion" status.
  • Once the team agrees to the final proposal, asignee consolidates the finalized the proposal in the original post, updates the branch, and post a comment saying "branch updated" with mention to Chair and the Secretariat. (Please do not change issue status.)
  • Chair confirms that the proposal is finalized and the associated branch is updated, and moved the issue to the "validated" status.
