# Change Order — Effort (Hours) Request

> Use when out-of-scope work cannot be fully funded from internal headroom (under-run slack +
> contingency) per the find-hours worksheet. Reason in HOURS/effort — no dollars, rates, or headcount.

| Field | Value |
|---|---|
| **Study / project** | CP-101 (example) |
| **Change order #** | CO-YYYY-NN |
| **Date raised** | YYYY-MM-DD |
| **Raised by** | (lead biostatistician) |

## 1. The out-of-scope work
_What is being asked for, and by whom (sponsor request / amendment / ad-hoc)._

## 2. Why it is out of scope
_New deliverable / added analysis population / unplanned interim / recurring "one-off" / exceeds net findable hours._

## 3. Effort estimate
| Item | Hours |
|---|---|
| Estimated effort for the new work | ___ |
| Found internally — under-run slack reallocated | ___ |
| Found internally — contingency drawn | ___ |
| Freed by deferring lower-priority work | ___ |
| **Shortfall requiring this change order** | **___** |

## 4. Timeline / critical-path impact
_Does absorbing or deferring push any critical-path deliverable past its date? New dates if work is re-sequenced._

## 5. Disposition
- [ ] Absorbed internally (no CO needed) — record the reallocation in the effort ledger
- [ ] Change order raised for the shortfall hours
- [ ] Work deferred / declined
