Mechanism MEC-01

Decision log with dissent

Record each consequential decision with its decider, the dissent, the options ruled out, and a review date, so the people it affects and later reviewers can see why it was made.

Where it acts

At Decision, one of the seven stages every consequential decision passes through. It records what was decided, who decided, and who dissented, at the moment of deciding.

Steps

Put the mechanism in motion

3 steps, in order. Check each one off as it is done; the records below show the work was done.

Records this mechanism keeps

What a team running this mechanism keeps, and what each record is for.

Decision record template

Fields for the decision, the decider, the options ruled out, the dissent, the review date, and the review owner.

Plain-language summary

One paragraph saying what was decided and why, written for the person the decision affects.

Review calendar entry

The review date, its owner, and the evidence the review will check.

Reuse-ready snippets

Copy policy, audit, and incident language

Use these snippets in requirements, audits, and postmortems with the mechanism permalink.

Policy requirement

Policy requirement (MEC-01 Decision log with dissent)
- Log every high-stakes change with its decider, the options ruled out, any dissent, and a review date with a named owner.
- Keep the log in the system of record, and link each entry from the audit and incident records that rely on it.

Product requirement

Product requirement (MEC-01)
- The receipt for each high-stakes automated decision carries the ID of the log entry for the rule it applied.
- The person decided about can reach a plain-language summary of that entry within two clicks of the outcome.

Audit evidence checklist

Audit evidence checklist (MEC-01)
[ ] Each entry names the decider, the dissent or its recorded absence, and a review date.
[ ] Each entry has a plain-language summary that can be shared outside the team.
[ ] Reviews were held on their dates, and each one recorded an outcome.

Postmortem trigger

Postmortem trigger (MEC-01)
Trigger review when a high-stakes change ships without a log entry or a dissent record, or when a review date passes with no review held.

Example usage

Recording a delayed launch

One scenario with each part of the mechanism in place.

How it plays out

A benefits agency logs its decision to delay an automated renewal tool. The entry records two options ruled out and a dissent from the call-center lead: error rates on Spanish-language forms were never tested. The deputy director owns a review in six weeks, and the tool's appeal page links to the entry.

Anti-patterns

Common failure cases and counterfactuals

Each case passes on paper and fails in operation. The counterfactual shows what would have worked.

Logs without dissent

The log records what was decided but not the options ruled out or who objected, so a later reviewer cannot tell what was weighed.

Counterfactual: Each entry records the options ruled out, the dissent, and a dated review with an owner.

Exception: An entry with no dissent is complete when it shows dissent was asked for and none was given.

Reasons kept in private documents

The reasoning sits in a private document or chat thread, so the people affected and later reviewers cannot find it.

Counterfactual: The entry lives in the system of record, and each receipt links to it.

Exception: Personal or security-sensitive details can be redacted, as long as the entry ID and the decision itself stay referenceable.

Diagnostics for this mechanism

Tools that size the risk this mechanism addresses.

Diagnostic

Delegation audit

Walks a team through one workflow against six questions and returns an exposure score, the permissions nobody can justify, and whether its decisions can be undone. Start here when the system keeps no decision records yet; use the record conformance checker once it does.
