HCD.3 — Diagnose Whether a Capability, Misconception, or Behaviour Limits Work

Type: Human Capability Development practitioner diagnostic pattern Status: Stable

HCD.3:0 - Use This When

Use this pattern when a named person’s later-Work demand is already recoverable, performance is inadequate or unstable, and different explanations would lead to different next Work. Begin by comparing the smallest rival set that could change the decision; do not begin by assigning training, practice, coaching, motivation work, or treatment.

The first useful result is either a qualified intervention target—the smallest changeable human limitation supported by current evidence—or a non-training return to the owner of the actual constraint, specialist question, or missing result. A target names what is supported, any still-plausible rival explanations, the conditions protected during observation, and what later observation could reopen it. A return names the blocked HCD decision and an exact retry condition.

The practical gain is stopping generic development Work before it consumes time or harms the person. Use HCD.1 when the later-Work demand itself is unclear. Use HCD.4 after a compatible demand and claim-level evidence exist and simultaneous capability claims must be compared. A separate programme comparison (HCD.2) may use a target or another qualified basis; HCD.3 stops at the target or non-training return.

Do not use this pattern to diagnose a medical disorder, prescribe a clinical or learning intervention, declare that development occurred, authorize surveillance, assign Work, or make safety, employment, provider, or treatment decisions.

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.

HCD.3:1 - Problem Frame

When Work goes badly, the visible human is often the easiest place to intervene. Yet the same observation can arise because the demand was wrong, the Method or source was missing, a tool or cue changed, the assignment or authority failed, workload or recovery was inadequate, a specialist return was absent, the response was not recognized as applicable, or the person’s capability really is limiting.

These branches have different owners and remedies. More practice can be useless when the task lies outside the claimed envelope, unsafe when a clinical or safety condition is current, and misleading when assistance or prompt design controls the result. Conversely, an endless list of possible causes is not a diagnosis. The comparison must become small enough to change a decision.

HCD.3:2 - Problem

The common shortcut is to transform “the result was poor” into “the person needs training.” It hides the evidence chain, turns a familiar intervention into a cause, and exposes the person to monitoring or employment consequences without a justified target.

The opposite shortcut refuses any bounded target while uncertainty remains. That makes practical diagnosis impossible even when controlled observations have eliminated the decision-changing rivals. The practitioner needs a conservative result that can name one qualified target, record the explanations considered and any still-plausible alternatives, and return questions for other owners. Eliminating the considered rivals leaves the stated evidence limits and reopen conditions in force.

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.

HCD.3:4 - Solution

Compare the coarsest decision-changing rival branches, run only safe and qualified observations, and return the smallest human limitation justified by the current evidence—or return the question to the owner of the surviving non-training branch.

HCD.3:4.1 - Bind the Diagnostic Use

Name:

the exact human holder and participating basis;
the HCD.1 demand account or equivalent qualified later-Work input, including configuration, conditions, horizon, and evidence window;
the observed gap and the HCD decision it could change;
the evidence collector, declared use, access conditions, privacy or worker-governance boundary, and direct owners;
the protected conditions and safe probe limit; and
the point at which a clinical, safety, legal, employment, target-domain, or other specialist owner must take over.

If the demand is absent or incompatible, stop with a non-training return for the exact missing scope or evidence. Do not diagnose a person against a job label, aggregate profile, or imagined future task.

HCD.3:4.2 - Compare Decision-Changing Rivals

Include at least the branches that remain plausible and would change the next Work:

Rival branch	Question that keeps it live
demand or envelope	Is the demand specified correctly and inside the capability envelope being relied upon?
applicability, access, expression, adaptation, or enactment	Is the response unavailable, or does a cue, context, interference, configuration, or performer arrangement prevent selection or use?
Method or description	Is the target Method missing, stale, disputed, or inapplicable?
tools and supports	Are AI, information, cues, access, environment, workload, recovery, or another support condition limiting?
assignment and organization	Is assignment, permission, authority, coordination, organization, provider access, or a required specialist result missing?
specialist condition	Does health, disorder, safety, ethics, law, or another specialist condition require its direct owner?
human change target	Does the evidence support a particular capability, knowledge, skill, discrimination, misconception, behaviour, self-regulation, or commitment as limiting and changeable?
measurement artefact	Could a scoring, recording, or interpretation error explain the poor indicator without the corresponding failure in Work?

Do not expand the set with every imaginable explanation. Include a branch when a credible current value or absence makes it decision-changing.

Too few or poorly linked observations, coupled conditions, contamination, or unsafe collection can prevent this comparison from distinguishing the live branches. Narrow the conclusion or give a non-training return that names the evidence limit, the next needed observation, and safe conditions for obtaining it.

Look for a missing intermediate performance, not just an absent basic skill or an unknown whole procedure. Use FPF B.1.5.EW to recover the relevant constituent–whole connections. In a stipulated dance case, the person has sufficient strength, holds the axis when stationary and recalls the figure, but loses balance during its rotation. Those observations locate a coordination question between the muscular actions and the figure; they do not establish a general lack of strength or memory. If existing observations already distinguish the decision-changing rivals, use them. Otherwise choose a suitable comparison of the rotation in isolation and in the figure, under domain-qualified conditions. Return the supported limitation or the unresolved alternative rather than prescribing more of whichever exercise is easiest to name.

HCD.3:4.3 - Probe Before Declaring Capability Loss

When a prior qualified capability or result exists and the differential can change the next Work, use an applicable E.23.CAE disposition before declaring loss or prescribing more practice. Return to a qualified reference condition without further development where safe, vary the smallest decision-bearing condition, and observe applicability, access, adaptation, enactment, and result separately.

A recovered response weakens simple global loss but does not prove transfer. Failure across reference and target conditions may warrant capability-claim revision only after demand, configuration, support, and measurement rivals have been addressed. If the probe teaches, primes, fatigues, changes exposure, or cannot be run safely, narrow the conclusion or return an unresolved differential that states the observation limit and its effect on the conclusion.

For any new observation, record the evidence collector, holder participation, declared use, protected conditions, access and privacy boundary, and whether another owner must interpret the result. Treat an assisting System’s inference as decision input. Acting on it requires separately established authority for the particular action.

HCD.3:4.4 - Record the Result

A qualified intervention target contains:

Result position	Required content
use boundary	Human holder, later-Work demand, configuration, horizon, evidence window, receiving decision, participation basis, and governance limits.
observed gap	Claim-sized Work observation, intended result or critical-error boundary, and why the gap matters.
target	The person’s difficulty with the required contribution and the smallest supported human change to target under the named conditions. A later decision selects any practice or other intervention.
evidence	Observations, work products, contrasts, inference rule, uncertainty, and contamination or measurement limits.
rival disposition	The explanations considered, any still-plausible alternatives, and their effects on the target and next observation. When none remain, keep the evidence limits and reopen condition explicit.
protected conditions	Method, task, tools, prompts, information, time, environment, assignment, authority, supports, and specialist routes held or bounded.
intended observation	The target change to observe, its conditions, and the claim that would depend on it. Explaining a result as an effect of the intervention through that target requires evidence for each link.
boundaries and continuation	Direct specialist or owner boundary, unsupported uses, and the condition that reopens the target.

Observed performance may be reported with its conditions before a causal explanation is established. A better score alone establishes neither a change in the proposed target nor the intervention’s effect through that target.

A non-training return contains:

Result position	Required content
actual owner or missing result	The direct Method, tool, assignment, organization, authority, specialist, evidence, or other owner and the exact result or value needed.
blocked HCD decision	The diagnosis or later development decision that cannot be made.
evidence and rival disposition	What is known, what remains unresolved, and why a human target is not supported.
safe interim boundary	What must not be assigned, inferred, prescribed, or used meanwhile.
retry condition	The exact new result, protected observation, owner decision, or compatible evidence that permits reconsideration.

HCD.3:4.5 - What Changes in Practice

A practitioner no longer asks, “Which training should fix this failure?” They ask, “Which live explanation would change the next Work, what observation distinguishes it safely, and what is the smallest human target the evidence actually supports?” A missing Method, prompt, authority, specialist result, or diagnostic observation is returned under its own name.

HCD.3:5 - Archetypal Grounding

HCD.3:5.1 - Constructed Positive Case: ImpactReview-17

ImpactReview-17 is a constructed pedagogical case. ImpactReview-17-Domain-Oracle-v1 supplies engineering correctness and criticality criteria for PumpWorks-Config-Baseline-42 and AI-Assist-M4. The baseline observations and neutral-probe results below are stipulated case data.

For human holder Engineer-P14, the constructed HCD.1 account demands independent review of AI-proposed change-impact claims under a forty-five-minute limit with current sources, configuration trace, auditable evidence, and bounded safety and maintenance specialist returns. The baseline stipulates correct source/configuration trace and evidence return in eight of eight cases, correct specialist routing in two of two relevant cases, and rejection of two of four plausible wrong AI claims. Both misses occur in unfamiliar variants and are labelled safety-critical only by the constructed oracle.

Several rivals would change the next Work. The applicable MethodDescription, source access, tool configuration, time, assignment, authority, and specialist route are present in the case, so those branches do not explain the two misses. An E.23.CAE-shaped neutral probe preserves those conditions. Engineer-P14 recognizes that independent checking is required but does not generate and test a competing configuration hypothesis on either unfamiliar miss.

HCD.3 therefore returns this qualified intervention target:

Generate and test an independent configuration counter-hypothesis before accepting plausible AI output in unfamiliar variants.

The stipulated review permits an ordinary reminder to construct and test a competing hypothesis, but the engineer must supply the case-specific rival and its test. In the proposed comparison, the neutral prompt is “Review this AI claim against the current configuration.” The other prompt adds “Before accepting it, construct and test a competing configuration hypothesis.” Neither supplies the alternative or tells the engineer which claim to reject.

The evidence is narrow: two unfamiliar misses inside eight constructed cases. A prompt-design rival remains live because the neutral prompt may have suppressed the counter-hypothesis move. The protected conditions are the same source, configuration, AI assistant, time limit, authority, and specialist routes. The intended observation is whether Engineer-P14 produces and tests a competing configuration hypothesis and rejects the planted wrong claim in each of two further unfamiliar cases: one first attempt with a neutral prompt, and one first attempt on the other case with an explicit counter-hypothesis prompt. Success with the reminder supports performance under that permitted condition and may justify returning prompt design to the Method/tool owner; it does not establish self-initiated use of the operation. Different cases leave case-difference uncertainty; the comparison informs the next decision without isolating a causal prompt effect. Reopen when the prompt, configuration, case family, source access, tool posture, time, observation count, or target-domain oracle changes.

The result is a bounded target for a later development decision, not an assignment to practice. Operational use needs qualified current domain criteria and observations for the actual person and Work, including evidence that distinguishes the live rivals.

HCD.3:5.2 - Missing Case: ReleaseWork-R9

Engineer-E27 has only a prospective HCD.1 demand hypothesis for ReleaseWork-R9. The actual Work occurrence, occurrence-produced result claim, occurrence-bound result record, representative observations, and compatible obtaining SYSE.21 supplier result required by XRI-21 are not recoverable.

HCD.3 returns a non-training return with diagnostic-evidence-missing. The blocked decision is whether any human capability, knowledge, skill, discrimination, misconception, behaviour, self-regulation, or commitment is the limiting change target. A MethodDescription, plan, target repertoire, curriculum, constructed demonstration, course completion, or platform score cannot discriminate the rival branches.

The safe interim boundary is: do not base training assignment, an inference of human deficiency, employment consequences, or a transformation claim on the unsupported HCD inference. Separate decisions require their own sufficient evidence and appropriate authority. Retry after a compatible HCD.1 demand basis and holder-specific evidence distinguish the live demand/envelope, Method, tool/support, assignment/authority, specialist, and human-target branches under the intended configuration and evidence window. Recovering a Work occurrence alone does not complete the diagnosis; the observations must be decision-discriminating.

HCD.3:5.3 - Unlike Case: Social-Anxiety Clinical Route

When an adult seeks treatment for social anxiety, return that question to qualified clinical care. A diagnostic label, symptoms, avoidance, or treatment request alone does not establish a target for changing a separately specified contribution in later Work. The current NICE social-anxiety guideline (BEH-05) places recognition, assessment, treatment choice, provider competence, safety, shared decision-making, and outcome monitoring with qualified clinical care.

HCD.3 returns a non-training clinical route whenever diagnosis, treatment choice, exposure or CBT content, clinical safety, consent, provider competence, or clinical outcome interpretation is current. It may preserve a legitimate later-participation Work question and the distinction between observed behaviour, support, transfer, and outcome, but it does not prescribe exposure, behavioural experiments, homework, counterconditioning, symptom targets, or provider arrangements. Retry HCD only when the person and clinical owner supply a bounded non-clinical Work question whose evidence can be used safely without taking clinical authority.

HCD.3:6 - Bias-Annotation

Recurring bias	Likely drift	Repair
training-default bias	A poor result becomes a course or practice assignment.	Compare decision-changing rivals and return the smallest supported target or a non-training result.
dispositional bias	A configuration-dependent observation becomes a stable trait, attitude, or motivation label.	Bind holder, Work, conditions, horizon, observations, and any still-plausible rivals.
tool-blame or human-blame bias	Responsibility is assigned to the AI tool or person before the joint arrangement is separated.	Vary protected conditions and keep human, tool, Method, prompt, authority, and specialist contributions distinct.
familiar-mechanism bias	“Forgot,” “misconception,” or “not motivated” substitutes for a controlled differential.	Use `E.23.CAE` where applicable and retain any still-plausible explanation that could change the next decision.
target-rhetoric bias	Naming autonomy, confidence, motivation, or practice is treated as evidence that it is limiting.	Require holder-specific evidence for the proposed target. A later claim that an intervention worked through that target also needs target-engagement evidence.
clinical appropriation bias	A disorder or treatment process is recast as development.	Return diagnosis, treatment, provider, safety, consent, and clinical outcomes to qualified clinical ownership.
surveillance bias	More data collection is assumed to be harmless and authorized.	Name declared use, participation, access, privacy or worker-governance conditions, and direct authority before collection.
intervention leakage	The target wording quietly names a programme, provider, schedule, or method.	Name the person’s difficulty with the required contribution, the smallest supported human change to target, and the intended observation; select any intervention separately.

HCD.3:7 - Conformance Checklist

The exact human holder and a compatible HCD.1 account or equivalent qualified later-Work input are recoverable.
The observed gap, configuration, horizon, evidence window, receiving decision, and protected conditions are explicit.
The rival set contains every credible branch that would change the next Work and does not expand into an unbounded cause catalogue.
An applicable E.23.CAE disposition is used before capability loss or more practice is declared when its differential can change the decision.
Method, tool, AI, cue, information, access, environment, workload, recovery, assignment, authority, organization, provider, specialist, and human-target branches keep their own kinds.
Any qualified target names the person’s difficulty with the required contribution and the smallest supported human change under the named conditions.
Evidence, uncertainty, the disposition of considered rivals, any still-plausible alternatives, protected conditions, intended observation, specialist boundary, and reopen condition are present.
A non-training return names the actual owner or missing result, blocked HCD decision, safe interim boundary, and retry condition.
Evidence collection names collector, declared use, holder participation, access, privacy or worker-governance boundary, and required direct owners.
The result authorizes no surveillance, assignment, employment action, specialist action, treatment, or development intervention.
The result claims neither target engagement nor transformation before later evidence supports it.
The receiver can identify the next observation, safe interim boundary, and owner of any returned question.

HCD.3:8 - Common Anti-Patterns and How to Avoid Them

Anti-pattern	Why it fails	Repair
“The score is low, so train the skill”	The score does not identify the required contribution, where the person has difficulty, or the rival explanations.	Recover the later-Work account and compare decision-changing branches.
“They know it when prompted, so the problem is solved”	Reference recovery does not establish unaided applicability, adaptation, enactment, or transfer.	Record the qualified differential and probe the earliest unresolved position.
“They missed twice, so capability was lost”	Small, configuration-bound evidence cannot eliminate support, prompt, envelope, or measurement rivals.	Preserve uncertainty and any still-plausible rival; narrow or return the target.
“Motivation is the cause”	Naming motivation supplies neither an observation of change nor a causal explanation.	Specify the proposed target and observe it. A claim that an intervention changed it and thereby changed a later result needs grounds for both links.
“The AI made the error” or “the human made the error”	The joint Method, prompt, source, review, and authority arrangement is hidden.	Separate contributions and use a crossed or otherwise discriminating condition where safe.
“A clinical technique is just another learning intervention”	HCD lacks diagnosis, treatment, provider, consent, safety, and clinical outcome authority.	Return the case to qualified clinical ownership and retain only a legitimate non-clinical Work question.
“The target is practice”	Practice is an activity intended to produce a change; it does not identify the person’s difficulty.	Name the difficulty making the required contribution, what must change, and the observation that would show that change.
“Diagnosis chooses the programme”	A target is evidence for a later decision, not a programme or authorization.	Keep programme comparison (`HCD.2`) separate; stop at the target or non-training return.

HCD.3:9 - Consequences

A development decision can focus on one evidence-supported target instead of a generic deficit, or stop early when the real constraint belongs to another owner. Rival explanations and governance remain visible, reducing unnecessary practice, unsafe probing, and employment overreach.

The cost is disciplined observation. Some cases remain unresolved, and a narrow target may reopen when prompt, tool, task, support, evidence, or specialist information changes. Using a qualified target to design development still requires a separate intervention choice. A claim that the intervention worked through this target requires later target-engagement and result evidence.

HCD.3:10 - Rationale

The smallest decision-changing target is more useful than a complete causal story. It is sufficient to change the next development question while avoiding claims about hidden mechanisms that the evidence cannot support. Recording the considered explanations, any still-plausible alternatives, evidence limits, and reopen conditions prevents “qualified” from becoming “certain.”

The non-training return is a positive result because it prevents misdirected Work and tells the receiving owner exactly what is needed. The specialist boundary is not a residual exception: clinical, safety, legal, target-domain, assignment, and employment questions retain their own authority even when human development is also relevant.

HCD.3:11 - SoTA-Echoing

The working question is: How can a practitioner identify a development-relevant human target without treating every poor result as a training need or a medical diagnosis?

The selected current line joins three bounded contributions. First, Melanson and Fahmie’s Functional analysis of problem behavior: a 40-year review (2023; BEH-01) supports the warning to distinguish maintaining conditions before intervening, but its clinical populations, controlled procedure, causal functions, and specialist safety arrangements are not generalized into HCD. Second, E.23.CAE separates envelope, configuration, applicability, access, adaptation, enactment, and actual capability change through an observation-first differential. Third, Sheeran and colleagues’ meta-analyses Self-determination theory interventions for health behavior change (2020; MOT-01) and Does increasing autonomous motivation or perceived competence lead to health behavior change? (2021; MOT-02) support an intervention-to-target-to-result evidence chain when explaining an intervention’s result through its proposed motivational target. A theory label or assigned technique is not evidence that the target changed.

A serious alternative is the generic training-needs interview or competency-gap score. It is fast and legible, but it commonly treats the selected measure as the cause, omits support and authority rivals, and moves directly from gap to programme. HCD.3 keeps those measures as evidence cues, then mutates the workflow into a bounded rival comparison and one target-or-return result.

This line does not supply a universal causal diagnosis, clinical protocol, intervention, or transfer claim. Human mechanism and intervention claims still require a direct source matched to the population, target, comparison, measure, horizon, support, and limit. Reopen when the holder, demand, configuration, prompt, tool, support, Method, assignment, authority, specialist result, evidence window, observation, declared use, or governance condition changes.

HCD.3:12 - Relations

HCD.1: supplies a same-holder demand account and evidence needs. HCD.3 may instead use an equivalent qualified later-Work input. Qualified inputs permit direct entry without a prescribed pattern sequence.
E.23.CAE: supplies differential dispositions when apparent loss, access, expression, adaptation, or enactment would change the next Work. Its result is evidence, not an intervention choice.
E.23.CDI: governs development-intervention and transfer evidence only after development is separately selected; HCD.3 does not perform that selection.
Melanson and Fahmie’s review (2023) (BEH-01): supplies only the bounded “differentiate before intervening” warning; its clinical procedure and population remain outside HCD.
Meta-analyses by Sheeran and colleagues (2020, 2021; MOT-01, MOT-02): supply target-engagement and intervention-to-target-to-result evidence boundaries; they do not make motivation the default cause.
The NICE social-anxiety guideline (BEH-05) and direct clinical sources: provide criteria for diagnosis, treatment, provider competence, safety, consent, and outcome interpretation. Clinical specialists exercise professional judgement; the person and other authorized actors make the decisions that belong to them. HCD.3 supplies the stop-and-route boundary.
Target-domain Methods and specialist results: provide criteria and evidence for correctness, quality, criticality, hazard, legality, and other domain questions in the diagnostic comparison. Qualified specialists make the professional judgements, and authorized actors decide the corresponding actions.
HCD.4: may receive a qualified target and any still-plausible rival as claim-level evidence for profile comparison; it does not inherit an intervention or mastery claim.
Programme comparison (HCD.2): may use a qualified target under its own Method and decision boundary. HCD.3 selects no programme and requires no programme-comparison result.
Employment, assignment, safety, legal, provider, organization, platform, and tool owners: retain their direct decisions and authority.
