Change Control Log — one controlled route for every change.
Projects rarely fail in one decision. They fail in forty small ones that never passed through a gate. This register records every change to scope, cost, and schedule across four impact axes — and routes each one to the approval level its impact demands.
What it does.
The Change Control Log gives uncontrolled change nowhere to hide. Every variation, concession, field instruction, scope change, design change, or claim gets a row: who raised it, what it touches, and what it costs across four impact axes — cost, schedule, risk, and HSE.
Routing is automatic and threshold-driven, mirroring the full product: cost at or above GBP 500k, schedule impact at or above 14 days, or HSE severity 3 and above escalates to the Project Director; cost at or above GBP 2m or schedule at or above 30 days goes to the Steering Committee. The dashboard keeps a running total of what is still open — because an open change is an uncontrolled commitment.
Inside the free edition.
- Interactive web tool — raise a change through a five-step impact wizard, watch it route through approval workflows, and collect signatures. Runs entirely in your browser; nothing is sent to a server.
- Dynamic Excel workbook — a 25-row change register with controlled dropdowns, automatic threshold routing, and a live exposure dashboard.
- Six change categories and eight engineering disciplines, written for capital projects and complex delivery organisations.
- Four impact axes per change: cost (GBP), schedule (days, critical path), residual risk, and HSE severity.
- Works in Microsoft Excel, Google Sheets, and LibreOffice Calc.

Questions, answered.
What is a change control log?
A single register that records every proposed change to a project’s scope, cost, or schedule and forces each one through a controlled route: raised, assessed for impact, approved at the right level, and closed. The free edition records four impact axes per change and routes each one automatically using the same escalation thresholds as the full product.
Is the Change Control Log really free?
It will be. The free edition launches without a sign-up wall once final release checks are complete. Until then, preview it here and register interest via the contact form — we will send it the moment it ships. The full instrument remains part of a stomwerk engagement.
Where does the web tool store my data?
In your browser. The web tool runs entirely client-side and persists to local storage — nothing is sent to a server. Clearing your browser data clears the register, so treat it as a working demonstration and keep the workbook as your durable record.
When should a change escalate beyond the project manager?
When its impact exceeds the approver’s delegation — and the thresholds should be written down before the change arrives. The free edition uses the full product’s defaults: cost ≥ GBP 500k, schedule ≥ 14 days, or HSE severity 3+ routes to the Project Director; cost ≥ GBP 2m or schedule ≥ 30 days routes to the Steering Committee.
