OPS-PROTECT-AND-DEVELOP - Prepare or learn while preserving promised service

Situation: A specialist has finished a first pass and could start new work, but an earlier result may return for correction. Some of the waiting interval could be used for preparation or learning.
Question: Which new work can proceed while the promised service remains feasible, and what counts as improvement?
First useful result or blocker: An operating choice that preserves the required correction window, identifies a useful auxiliary unit and retains the customer’s whole waiting interval.
Start with: OPS.11.1 to recover the work and shared resources; then combine OPS.8.1, OPS.8.2 and the capacity, scheduling and quantity methods for the consequences that affect the choice.
Stop or return: Use a sufficient arrangement. Return an impossible promise to its conditions or OPS.13; return the value of the proposed learning or improvement to HCD, DOCA or ME.

Keep the unfinished service in the operating model. In this constructed case, report X arrived at hour −2 and its first pass finished at zero. At hour one, a separate reviewer either accepts it or supplies a correction requiring two uninterrupted specialist-hours. If correction is needed, its completion supplies the promised result, required by hour three. New session Y needs the same specialist for four uninterrupted hours, is ready at zero and must finish by seven. OPS.11.1 retains the shared specialist and feedback event; OPS.15.1 distinguishes first-pass completion from delivery of the required result.
Construct a response that can use the actual feedback. Two hours of correction and four hours for Y fit within seven available hours, but that total does not settle their placement. OPS.10.2 shows that starting Y at zero would postpone correction until 4–6, too late for X. OPS.8.1 - Choose Work-Release Rules When Earlier Work Can Return preserves the 1–3 correction window. If X is accepted at one, run Y at 1–5; if it returns, correct X at 1–3 and run Y at 3–7. This rule uses information available at the choice and meets both stated requirements.
Use only an auxiliary unit that leaves the protected action ready. Suppose a prepared exercise takes half an hour and its closure and restoration of the specialist’s work context take another quarter-hour. No earlier recall is included in this case, and the required resources remain available. OPS.8.2 - Use Protective Capacity While Keeping It Available fits the unit at 0–0.75, before the feedback at one. A longer indivisible lesson could consume the correction window. HCD.2 still has to supply meaningful practice and feedback; the timing calculation alone establishes no learning gain. DOCA.1/.4 or ME.1/.11 can instead develop a preparation opportunity or method trial with its own full burden.
Measure the promised result and compare the cost. OPS.15.1 retains X’s wait from −2: three hours if accepted at one and five if corrected by three. Y waits five or seven hours from its own arrival. The exercise neither erases that waiting nor creates an additional accepted customer result. OPS.14 can compare its incremental financial consequences when that changes the choice; HCD or ME establishes its intended development contribution.
Reopen the affected relation when the condition changes. Move the review to hour two and retain the two-hour correction and deadline three. Even an idle specialist can finish only at four. OPS.10.1 identifies that finite timing obstruction; holding all new work cannot remove it. Obtain earlier usable feedback, a correction method that actually fits, or a revised commitment through OPS.13. Preserve the unaffected resource and waiting definitions.
