HCD.2:5.2 - Unknown Audience: FoundationsProgramme A, B, and C

A learning-product author has two intended outcomes: checked performance of complete selected work tasks, and lower effort to learn a previously untaught Method while preserving correctness. These are design aims, not observed gains. The author has an audience hypothesis, three 340-hour compositions, and no named learners. A allocates 202/96/42 hours to general/domain/joint application, B allocates 88/204/48, and C allocates 136/136/68. C is described in more detail; that detail does not establish dominance.

The HCD.2 boundary returns a learning-product design question to HCD.28: preserve the two outputs, audience assumptions, three alternatives, learner and teacher resource coordinates, support assumptions, and individualization questions. Use C’s existing material and develop only the smallest missing A/B fragment for one closed task family with the same output, entry assumptions, representative attempt, feedback, retry, access, and resource account. Do not fabricate one future learner or require three complete courses before comparison becomes useful.

If the learner budget falls from 340 to 204 hours while both outputs remain fixed, none of the three original candidates is launchable as described. Multiplying every activity by 0.6 or hiding reading and practice outside the budget does not close the task. The return asks for a new candidate that identifies the removed or replaced 136 hours and preserves the mechanisms needed for the outputs. The separate 240-hour teacher calculation does not replace learner time or establish a competent available service. A 170-hour ThinkingFoundations-only offer answers a narrower output question and therefore is not an improved version of the same candidate set.
