MDMC Software Management


This section is only relevant to active developers of MDMC, rather than general contributors.

MDMC uses Git/GitHub for version control and ZenHub to implement aspects of the Agile methodology.


All issues are assigned a priority label. Theses are inspired by Quantified Task Management.

P5: (IMMEDIATE) For emergencies. Drop everything and fix this issue.

P4: (IMPORTANT) Top priority in the development cycle, except for emergencies.

P3: (NORMAL) Should be completed in current development cycle.

P2: (SOONISH) Might be completed in current development cycle but not essential.

P1: (EVENTUAL) For future development cycles.

P0: (OPTIONAL) May not ever be completed.

PT: (TRIAGE) Yet to be prioritised.

By default, all newly created issues will have priority PT. Issue contributors are instructed not to assign priorities, as this should be done by active developers.

Story points

All issues are assigned a number of story points which attempt to quantify the expected development resources required for the issue. Story points are a relative measure and do no correspond to a specific amount of developer hours, as this will vary dependent on the currently active developers; however an attempt is made to equate 1 story point to ~0.5 developer days.

As with priorities, story points should be specified by active developers.


New Issues

All newly created issues should go here. An active developer should then determine:

  • the priority of the issue;

  • the number of story points of the issue;

  • and if it needs to be included in the current development cycle or not (move to Backlog if yes, move to Icebox if no).


Issues which will not be worked on in the current development cycle. No issue with a priority higher than P2 should be put in the Icebox. Before a new development cycle, Icebox issues should be checked to determine if they should be moved to Backlog.


Issues worked on during the current development cycle. No issue with a priority lower than P2 should be in the Backlog. Issues should be ordered based on priority i.e. all P5 at the top, all P2 at the bottom. During sprint planning, the Backlog should be surveyed to determine which issues will be included in the next sprint.

In Progress

Issues that are being worked on should be moved to the In Progress pipeline; this helps protect against duplication of effort and reduces the likelihood two developers will be working on the same part of the codebase. Issues that are In Progress may or may not have an associated pull request (PR).


Issues should be moved to Review/QA once they have a PR which has a reviewer allocated.


Issues which are closed will automatically move to this pipeline.


Each sprint is represented by a Milestone; this allows ZenHub to provide burndown reports and velocity tracking. During sprint planning, any issues to be added to the sprint should have the relevant Milestone set. The issues within a specific sprint can then be viewed by filtering the ZenHub board by Milestone.
