HCD.20:8 - Common Anti-Patterns and How to Avoid Them

Anti-pattern	Failure	Repair
Cohort equals group	An enrolment number dictates every interaction.	Separate scales and derive each action’s capacity.
Division of labour equals learning	One member supplies the operation the others were meant to learn.	Allocate the personal contribution and a suitable later attempt.
Mandatory private attempt	A novice must invent an unavailable method before useful modelling.	Choose visibility and help for the actual learning purpose.
Observer equals spectator	A potentially useful role is either dismissed or accepted without an action.	Specify and inspect the observer’s contribution, then supply necessary personal execution.
Weekly-hours illusion	Adequate totals hide simultaneous demand.	Compare the live window with qualified available capacity.
Group discount	Reduced paid help conceals participant work and quality loss.	Compare whole burdens and the contribution actually supplied.
Automatic regrouping	Every difficulty triggers social disruption.	Repair the task, support or material first when that is the supported cause.
