IS.5:4.1 - Recover the practice that should remain obtainable

Start from the current undertaking and what actual use has shown. State the continuing result, its recipients, important case families and conditions. Separate three questions:

1. Should the target practice continue for this use?
2. What contribution is needed for it to remain obtainable?
3. Who should perform or provide that contribution?

A decision to keep the practice does not answer who should provide it. A decision to end a grant does not establish that its dependent work can safely stop. Use the already sufficient result of A.3.1.MI, including its non-use and adverse results; do not reopen the entire introduction merely because the decision now concerns continuation.

Follow an ordinary case and one consequential variation. Ask what happens when the usual expert is absent, an input is ambiguous, a source changes or demand overlaps with another obligation. Select variations because they can expose a particular dependency, not to demonstrate every conceivable failure.

Recover actual support from the work: who supplies the difficult judgement, restores access, selects the current method variant, detects an obsolete instruction, answers a late question and authorizes an exception? A support contribution can be distributed among a performer, an AI service, a source maintainer and a manager. There need not be a support office or one person who owns them all.
