Calculator Inputs
Rate each checklist item from 0 to 5, where 0 means missing and 5 means fully ready. Adjust weights to fit your governance model.
Example Data Table
This sample shows how a mid-risk infrastructure change might be scored.
| Checklist Item | Sample Score | Sample Weight | Sample Note |
|---|---|---|---|
| Business Justification | 5.0 | 10 | Strong business case approved. |
| Scope Definition | 4.0 | 10 | Boundaries documented with assumptions. |
| Impact Assessment | 4.5 | 12 | Customer and system impacts reviewed. |
| Schedule Review | 4.0 | 10 | Window avoids major business events. |
| Cost Review | 3.5 | 8 | Minor overtime cost expected. |
| Risk Assessment | 4.0 | 15 | Main technical risks mitigated. |
| Stakeholder Alignment | 4.5 | 10 | Sponsor and support teams aligned. |
| Testing Readiness | 3.5 | 10 | Acceptance evidence available. |
| Rollback Plan | 3.0 | 8 | Rollback documented but needs rehearsal. |
| Documentation & Training | 3.5 | 7 | Service notes and guides updated. |
Formula Used
Normalized Weight = Item Weight ÷ Sum of All Weights × 100
Weighted Contribution = Item Score ÷ 5 × Normalized Weight
Checklist Score = Sum of All Weighted Contributions
Critical Gate = Average of critical item scores ÷ 5 × 100
Decision Index = Checklist Score × 0.75 + Critical Gate × 0.25
This method keeps the checklist flexible because the reviewer can rebalance weights. It also protects governance quality by giving extra emphasis to critical controls.
Critical controls in this calculator are impact assessment, risk assessment, testing readiness, rollback planning, and documentation with training readiness.

Frequently Asked Questions
1. What does a score of 5 mean?
A score of 5 means the item is fully addressed, well documented, and ready for approval. Evidence should be clear enough for reviewers to validate quickly.
2. Why can I change the weights?
Different organizations prioritize control areas differently. Adjustable weights let you mirror your governance policy, board expectations, and operational risk appetite.
3. What happens if weights do not total 100?
The calculator normalizes them automatically. That keeps the final score mathematically consistent while still respecting the relative importance you assigned.
4. Why are some items considered critical?
Impact, risk, testing, rollback, and documentation usually determine whether a change can be executed safely. Weakness in these controls often causes failed implementations.
5. Is this calculator suitable for CAB meetings?
Yes. It gives a clear summary, consistent scoring model, and export options that work well for change advisory board reviews and approval records.
6. Can I use half-point scores?
Yes. The inputs accept increments of 0.5, which helps reviewers express partial readiness without forcing rough whole-number judgments.
7. What is the difference between Checklist Score and Decision Index?
Checklist Score reflects all weighted items. Decision Index blends that result with critical control performance, so weak gate items reduce the final recommendation.
8. Can this support audits and post-implementation reviews?
Yes. The exported summary and detailed scoring table help show how the decision was made, what evidence existed, and where controls were strong or weak.
