Good governance is not a thick policy document.

For this course, governance means small durable rules that protect state contracts after the original maintainers move on.

Write rules around high-risk changes

Useful governance rules often cover:

  • new DVC-tracked data
  • parameter changes with metric impact
  • pipeline graph changes
  • experiment promotion
  • release bundle changes
  • remote and retention changes
  • recovery route changes

Example:

Any pull request changing dvc.yaml, dvc.lock, params.yaml, or publish/ must run the relevant verification route and explain the state contract being changed.

That rule is specific enough to review.

Keep governance close to the work

Rules should live where maintainers will see them:

  • review guide
  • release guide
  • recovery guide
  • pull request template
  • Makefile command names
  • CI status checks

Governance hidden in a forgotten document does not protect the repository.

Rules should teach what they protect

Weak:

Follow DVC best practices.

Stronger:

Do not merge DVC metadata changes unless the required remote objects are available to CI and another maintainer can restore the state from a clean checkout.

The stronger rule names the contract: shared recoverability.

Governance should stay small

If every change requires the same heavy ritual, people will bypass the rules.

Use different review depth for different risk:

Change Reasonable rule
typo in documentation normal review
parameter affecting metrics params and metrics review
release bundle change release audit route
remote migration recovery and rollback plan
retention cleanup dry run and approval

Small rules survive longer.

Review checkpoint

You understand this core when you can:

  • write a rule for a high-risk state change
  • place governance where maintainers will use it
  • explain which contract a rule protects
  • keep rules proportional to risk
  • turn repeated review comments into durable guidance

Governance is successful when it makes the right action easier to repeat.
