Bug Priority/Uplift Management

In general we'd target to land only on Nightly (both fixes and features), and land on Beta when requested/really have to. With that idea we adopt a similar way of the P-system that P1 means "this Nightly cycle" while P2 refers to the "future Nightly cycles". Whiteboard tags involved with above principle are:

  • For bugs considered in a specific Sprint, 3 tags will be added
    • [FNC]: short for "Fennec"
    • [SPT#XX]: Stands for the Sprint number XX (each Sprint period is defined in above)
    • [MVP] or [BL] or [INT]: stands for "MVP (must have)", "BackLog" (may have), and "INTerrupt (unplanned)", respectively
    • For example a bug with whiteboard [FNC][SPT#57.1][MVP] means it's a bug we targe to get resolved in Sprint #57.1.
  • For bugs that we intend to uplift to Beta, we'll add both "[FNC]" and "[PLANNED_UPLIFT]" in the whiteboard field. So people (e.g., Release Management) can get the visibility of potential uplifts for tracking.
