How to keep a useful business decision log
What should a business decision log record?
Record the question, decision and status, decision owner and date, supporting reason, and any conditions or review trigger. Link later decisions to earlier entries so the current position is clear.
Small decisions often disappear into email threads and meeting notes. When the reason behind a choice is lost, the team may reopen it later without knowing what changed.
Record the decision and its context
A decision log does not need to capture every discussion. Use it for choices that affect scope, timing, responsibilities or expenditure. Give each entry a date, a short description and the person who had authority to decide.
Record the main reason and any conditions. A decision made while waiting for information should not look the same as a final approval.
Suggested fields
- Question being decided.
- Decision and current status.
- Decision owner and date.
- Reason and supporting reference.
- Conditions or review trigger.
Make changes visible
If a later decision replaces an earlier one, link the two records. Preserve the original rather than silently changing its wording. This helps a colleague understand the sequence without reading every message.
An example might be choosing a provisional delivery date while a supplier confirms availability. The log can state that the date is tentative and identify the condition that would make it final.
Keep sensitive discussions in the appropriate restricted record. A general operational log can point to the authorised source without reproducing confidential details.
Review a handful of entries each month. If people cannot tell which decisions are current, simplify the statuses. A useful log answers three questions quickly: what was decided, who decided it and when it should be reconsidered.
General business-process information. Check the circumstances and seek appropriate professional advice for contractual, legal or specialist decisions.
