The interval is the decision
There is no deny and no wait. Only how long.
Ask someone to accept a risk and they will do neither — treat acceptance as a choice and you have handed them a third door: do nothing. The risk is already on the books, so the only real decision is the duration. And the duration you pick commits you to a response, which is what makes it the severity decision rather than a form field.
1–24 hoursA P1 incident. The answer is pull the plug — saying you will not carry this past today is saying stop the thing now.
1 day – 1 weekStill an incident, a lower grade: assemble the team, decide, change, report back.
1 week – 1 monthA project for a team that already exists. The default — short enough to force a first decision, long enough not to be an incident.
1–3 monthsAssemble and fund a team.
Beyond 3 monthsYou are not doing anything — you are waiting to see. A legitimate answer that should be said out loud rather than dressed up as a plan.
Anything under a week is an incident
The rung simply names which grade. If you picked a short interval, you have already declared an incident — the only question left is whether the organisation is behaving like it.
Distance to the line sets the clock
The further above the acceptable line a risk sits, the sooner it should return to the desk: roughly a month far above, three months mid, six months at or near the line.
An unaccepted risk is critical
A risk nobody has accepted is critical for whoever holds it, until something above has accepted it — because right now that person is personally accountable. It belongs on their dashboard today.
An interval you cannot honour is a finding
If the interval implies "pull the plug" and the capability to pull it does not exist, that is a finding — not a scheduling problem. It is where this page meets the plug profile.
