HCD.6:0 - Use This When

Use this pattern when a named human contribution and a capability-development Method have been selected, but the person still needs a task in which to recognize the situation, act, obtain an inspectable result, receive feedback and improve the action. Begin with the target action and target-domain truth; do not begin by changing names, adding difficulty, or copying a production task without a learning purpose.

The first useful result is a representative practice set: a sufficiently whole task family with a worked demonstration or explanation where useful, a first attempt, repetitions or variations selected for the practice purpose, target-domain success and critical-error criteria, permitted help, feedback and correction opportunities, and progression or return conditions. The set states what each task is intended to expose. It does not establish that the tasks were performed or that capability changed.

The practical gain is an interpretable attempt. A practitioner can tell whether the person failed to calculate, to recognize the applicable Method, to challenge an unsupported source, to coordinate a specialist contribution, or to act when the supplied evidence is sufficient. A warranted refusal and a supported continuation can both be correct in different cases.

Do not use HCD.6 to invent target-domain correctness, turn a worked answer into learner evidence, schedule all repetitions, provide unavailable teachers or tools, or assess later capability. HCD.5 supplies the selected development Method; HCD.7–HCD.8 supply needed support; HCD.9–HCD.10 enact and vary practice; HCD.11–HCD.13 interpret performance, transfer, and retention.

When the practical question is how the person could move between different ways of acting, use the local model from HCD.4:4.2.1–4.3.1 or an equivalent qualified account. HCD.6 connects a proposed change to learning activities, help and observations, and can design alternative pathways through it. The model describes possibilities; the selected pathway plans opportunities; the learning trajectory records what was actually attempted and observed. A simple correction can still use one task without a larger progression model.
