Team Practices Group/Measuring Types of Work

Pilot Study on Maintenance Fraction
Several teams were asked to measure their maintenance fraction for at least two weeks. We created new Phabricator tickets to facilitate this. Five teams have confirmed numerical results, varying from 25% to 76% maintenance (compared to new functionality). We identified many definitions of Maintenance, some orthogonal and some conflicting. We did not reach consensus on a single definition. Several teams are continuing to track this data.

Category A: Lights On
"Keeping the lights On"

Something essential will fail immediately (days? hours?) if this work is not done.

Category B: Maintenance
"Maintenance"

anything which keep search ticking, but doesn't related directly to our goals

Something essential will fail or degrade fairly soon (weeks? months?), or will cost much more to fix later, if this work is not done now.

Category C: New Projects
"Investment/New Projects"

Functionality that is not currently available.

Can a team be their own customer? If a team delivers functionality to themselves, to make their own work easier/cheaper/better, is that category C, or B?

So this includes *all* new features, even if they are relatively minor tweaks to existing functional areas?

Tech Debt

meta-work

Category D
Supporting others

Developers/Maintainers and Upstream projects and who (if anyone) is tasked with fixing bugs in extensions/code that no existing team/individual is currently (officially) working on.

Category E
Internal to team goals

Category J
Interrupt. Work that is added to a to-do list (or just done) on a few days notice or less; work that is done before work that is both planned and high-priority.

Category F
most strategic in terms of achieving our mission

Fulfills a quarterly goal.

Category G
Not Strategic. Shouldn't be doing it.

Does not fulfill a quarterly goal.

Meeting Goals
1) Figure out how to meet request for teams to report on maintenance fraction

1a) Clear standards across groups

2) Figure out what teams want to measure for their own use

3) Make sure we know how to proceed

3a) clarify vs other dimensions

Why is Terry asking for the three categories?

 * WMF-level planning, budgeting


 * Katie: you want to do this to justify your hiring needs.


 * David: Can also use this [ongoing maintenance cost] to justify sunsetting things.

Why is Lila asking for her categories, which are slightly different?

 * maybe Lila wants some of this to figure out if a team belongs in which section?


 * Lila's categories in the notes are specific feedback to one team or role, not everybody

Is this all Engineering, or all Foundation?
Engineering.

What should we call Maintenance vs New Work, as opposed to the other possible dimensions?
Proposed: Maintenance Fraction.

Can we differentiate between A and B?

 * Greg - no


 * Katie - sort of - sort of have AB/Interrupt and AB/Non-Interrupt


 * B is debt


 * Does anyone have a rule for differentiating A from B that could work for most teams?


 * no

Is there stuff that is inward-facing that belongs to C?

 * no?

Does C include prototyping new things, researching existing things?

 * We probably have a lot of edge cases and maybe should do card sorting or other offline activity to get our collective judgment in sync

Proposed definition for C:

 * C is work that produces functionality that a non-foundation person would see/use.


 * This doesn't work for teams with no external customers. Those teams can try counting other Foundation teams as their Category C customers.

How are we measuring?

 * We will create a new tag to track this.


 * Some teams are mostly AB or mostly C. to make it easier, they can tag just AB or just C, and assume all other tasks are the other category.


 * Joel can create custom reports on other query-able factors (VE uses project column already)

Next Steps:

 * Joel: confirm definition (and check with Terry).


 * All: Send suggestions for names for tag AB and tag C.


 * Joel: continue/initiate email discussion on other categories


 * continue in email (inc. mailing list) until and unless another forum becomes better


 * All: Send edge case examples to Joel - how to measure follow-up discussion
