Rseng Community Metrics

Community health metrics

A community's health can be measured, and the CHAOSS project has standardized how: metrics for growth, responsiveness, retention and risk that turn "the community feels quiet lately" into checkable numbers. The same discipline as rseng-software-metrics applies unchanged: metrics LOCATE community problems, humans judge them; trends beat snapshots; and every metric can be gamed, so keep them plural and tie them to actions.

The metrics that matter, and their sources

Nearly everything comes from data the forge already has - git history, issues, PRs, reviews - all computable by an agent:

• Growth and activity: new contributors per period, active

contributors (authored, reviewed, triaged or commented - count ALL contribution kinds, the rseng-citation-metadata lesson), contribution volume by type.

• Responsiveness: time to first response on issues and PRs

(the promise rseng-community-governance made checkable), review latency, time to merge or close. First-response time is the single best predictor of whether a first-time contributor returns.

• Retention and the funnel: how many first-time contributors make

a second contribution (the conversion rate), casual-to-regular progression, time since last activity for previously regular contributors (quiet departures are findable before they are final).

• Risk: bus factor (what fraction of recent work concentrates in

how few people - the elephant-factor framing), single-maintainer subsystems, organizational concentration when affiliation is known.

Compute from git log, the forge API and the tracker; CHAOSS tooling (Augur/GrimoireLab-class) automates it at scale, but a scripted quarterly pass covers most research projects (a natural milestone-review input - rseng-code-review).

Interpreting honestly

• Stage calibrates everything (rseng-quality-framework's tiering

instinct): a two-person analysis-code repo with bus factor 1 is normal; infrastructure with bus factor 1 is a risk register entry. Compare the project against its own history first, peers second, absolutes never.

• Watch trends, alert on inflections: slowly rising first-response

time is load or fading attention - both actionable; a cliff after a maintainer change is a succession problem (rseng-community-governance).

• Name the denominator: "12 new contributors" means nothing

without the period and the definition; publish definitions with numbers so the metric survives scrutiny (rseng-research-integrity's spirit applied to community claims).

• Diversity and affiliation metrics involve personal data: use

public information, aggregate, and route anything finer to policy (rseng-regulatory-compliance).

From numbers to actions

Every reported metric ends with a routing, or it is a vanity dashboard:

• Slow first response -> triage rotation and a stated timeframe

(rseng-community-governance, rseng-project-tracking).

• Poor first-to-second contributor conversion -> onboarding fixes

(rseng-contributor-onboarding owns the funnel).

• Support load rising in issues -> FAQ and docs routing

(rseng-user-support, rseng-documentation).

• Bus factor concentration -> knowledge spreading: rotation,

documentation, succession planning (rseng-maintenance-sustainability).

• Good numbers -> tell the community; measured health is a

celebration and a grant-report asset (rseng-science-communication, rseng-management-planning).

Report metrics to the community transparently on a cadence - a short health section in the periodic digest (rseng-project-tracking's high-level log) normalizes measurement and builds trust; surprise metrics deployed in conflict destroy it.
