HCD-GROUP - Make joint activity develop the intended personal contribution

Situation: A shared answer is good, but it is unclear what each participant did, or the proposed interaction cannot fit the available people, time and help.

Question: Which contributions make learning together useful, and how can the task elicit them under a feasible arrangement?

First useful result or blocker: A justified individual or group option and, when needed, a shared task with usable personal actions, material transfers, feedback and recovery.

Start with: HCD.20 - Compose and Compare Arrangements for Individual and Group Learning when the configuration is unsettled; enter HCD.22 - Design Shared Learning Tasks with Necessary Individual Contributions directly when the target and arrangement constraints already exist.

Stop or return: Stop when the comparison or task changes the next design decision. Return missing qualified help to HCD.7/.8 and a disconnected product route to HCD.28. Personal performance, the common product, team capability and the material’s contribution require their respective observations.

A cohort of 24 need not discuss as one group. Two three-minute contributions each plus six minutes of reconciliation give an initial bound of four people in thirty minutes, excluding separate help. The worked construction adds six minutes of qualified help per group and staggers the starts, allowing two mentors to make all six visits before the dependent personal actions. HCD.20 shows the participant and mentor timeline and the changed burden. At a shared instrument, meaningful observation and operator turns produce different constraints; the discussion formula does not determine that group size.

To establish or change actual membership and contact, use HCD.21. To develop understanding through reasons, use HCD.23; for evaluative judgement and revision, use HCD.24; for a relation that must reach another project, use HCD.25. A group whose work has drifted can use HCD.26, while incompatible preparation, material transfers or return windows lead to HCD.27. Each method returns the actual contribution and its limits to the arrangement.
