HCD.3:0.1 - Working Terms
| Name in this pattern | What it denotes |
|---|---|
| diagnostic question | A bounded question about which live explanation best accounts for an observed later-Work gap and would change the next Work. It is not a medical diagnosis. |
| rival branch | A materially different explanation whose survival changes the next observation, owner, or development question. |
| human limitation | A difficulty this person has in making a required contribution under the named later-Work conditions. Current evidence supports treating that difficulty as changeable and relevant to the decision. |
| qualified intervention target | The smallest supported human limitation, with evidence, any still-plausible rivals, conditions, intended observation, specialist boundary, and reopen condition. “Intervention target” names what a later choice might try to change; it selects no intervention. |
| non-training return | A return to the owner of a nonhuman constraint, specialist question, or question outside the demand envelope; or a return naming evidence needed before a human target can be justified. |
| protected condition | A condition held stable or bounded so that an observation can discriminate rivals without quietly changing the holder, task, tool, authority, or support arrangement. |
| observed target change | A difference in the selected target between observations under stated conditions. It can inform the next development decision before its cause is established. |
| target engagement | A change in the selected target attributable to an intervention. Evidence must concern that target and justify the attribution; a theory label or assigned activity does neither. |
The diagnosis concerns the person’s difficulty making the required contribution under the named conditions. A low score, poor result, behaviour label, or inferred latent state can inform the diagnosis but does not by itself show what human change would help.
