HCD.3:3 - Forces

• A familiar human explanation is actionable, while Method, tool, authority, organization, environment, or specialist constraints may be more decisive.
• One observation is cheap, while a target must survive the rivals that would change the next Work.
• A controlled probe improves discrimination, while the probe can teach, prime, fatigue, expose, or otherwise change the person.
• Assisted performance reveals a joint result, while the human limitation may concern applicability, access, adaptation, enactment, or independent challenge.
• Motivation language is easy to apply, while change in the proposed target needs evidence beyond a theory label or assigned technique.
• A narrow target supports later design, while a diagnosis that is too broad becomes a trait label or a curriculum in disguise.
• Useful evidence can be collected, while privacy, consent, worker governance, clinical safety, and employment authority constrain collection and use.
• A specialist boundary protects the person, while HCD must still preserve any legitimate non-clinical Work question.
