# Change control

**Settings → Change control**, for PMO managers. Shown while the **Change management** feature is on.

## Who decides

The approvers a submitted [change request](/portavi-docs/governance/change-requests.md) waits for:

* **Parent component owners**: the programme owner for a project, plus the portfolio owner when the programme sits in a portfolio; the portfolio owner for a programme. A component with no parent owner falls back to any PMO manager.
* **Any PMO manager**: one PMO manager's approval is enough.
* **Parent component owners and any PMO manager**: all of them must approve.

Every named approver must approve; the first rejection closes the request.

## Tolerances

How far a finish date or a budget total may move from its **baseline** before a change request is required. The baseline is set when the component is created and reset each time a change is applied, so the tolerance is measured against the last agreed value, not the current one.

* **Date tolerance (days)**: 0 means every move needs a request.
* **Budget tolerance (%)**: the share of the baseline a budget may move without a request.
* **Budget cap**: an absolute limit on top of the percentage, so a small share of a large budget is still checked. Leave it empty for no cap.

Changes to the policy apply to edits from that point on; requests already open keep the slots they were given when submitted.
