OPS.13:5.5 - A review must leave time for the response
An accepted report is due at hour fourteen. Once its validated input is available, analysis needs three uninterrupted hours and release needs one more. These operations and their resources are available in that order until fourteen. The latest usable input is therefore hour ten.
At hour seven, an input failure occurs. A supplied recovery method needs two hours after authorization; its qualified performer and resources are available immediately. Authorization must occur by eight if recovery is to supply the input by ten. The next routine review at nine is too late: even immediate authorization then gives input at eleven, leaving analysis until fourteen and requiring release from fourteen to fifteen, outside its available window.
Instead, suppose detection takes at most fifteen minutes and conveying the result and deciding together take another fifteen. Recovery can start by 7.5, finish by 9.5, and be followed by analysis until 12.5 and release until 13.5. The response preserves half an hour before the deadline under these stated bounds. The signal needs to reach the person who can authorize recovery; an updated chart that nobody uses would not supply this response.
Now change one fact: the recovery resource cannot start before ten. Recovery could supply input at twelve, but the three-hour analysis would already overrun its availability until fourteen; release would require a further hour. Sixteen is only the arithmetic end if those windows were extended, not a supported delivery time. Faster notification alone cannot restore the promise. Obtain a different workable remedy or an agreed service revision. The earlier calculation remains valid only with its earlier availability premise.
These times illustrate a constructed operating choice, not a measured service probability.
