PSD.17:4.4 - Choose continuation or a bounded intervention

State who can choose, which continuation options are actually available, the intended participation or decision-return consequence, protected conditions, resources and period. If the available evidence supports retaining the present arrangement, record that choice and the conditions under which it applies. For a selected intervention, state what would stop, narrow or redirect the attempt.

Use C.11 for an already formed bounded choice. Before developing or commissioning a new inquiry, use C.11.DUA to compare its attainable contribution with formulation, design, participant and facilitator time, access, interpretation, delay and displaced work. A missing formulation, alternative or probe-design result can remain the limit on a stronger answer; acquire it only when the current question warrants that work.

Keep the choice local. A team may change its own case discussion, mentor arrangement or presentation of examples under its remit. It cannot thereby compel another team to adopt a Method, expose protected client information, certify practitioners, or decide the client’s investment. An invitation, a receiving team’s agreement and a service-wide rule have different authority and participation consequences.

Use the best qualified judgement proportionate to the decision. A reversible exercise with non-sensitive material may proceed on a stated mechanism hypothesis and modest evidence. A consequential service change may require stronger capability, professional, participant-protection and governance results. Obtain them directly; the cultural account does not invent consent, safety or competence.

Retain any serious alternative and expected loss that matter to the choice. The useful return can be “try one receiving exercise for this cohort, keep the present route for experienced staff, and do not extend the change until an independent receiving use has been observed.” That is a completed bounded decision even though its later effect remains unknown.
