What this exercise can and cannot establish
This exercise checks the completeness and consistency of boundary reasoning. It does not supply a morally unique answer or pretend that the practitioner represents every affected person.
This is original learning material, not a reproduced official course. Mechanical checks have determinate answers within the stated case. Worked comparisons for open judgements show defensible reasoning, not the only possible model. Specialist pedagogical review is not recorded.
The case
Fictional case: a council proposes replacing its assisted benefits-application desk with a digital service. The finance director sponsors the proposal and counts annual administrative cost as success. A vendor controls the software design. The council controls staffing and opening hours. An analyst advises using completion rates from current online users. People unable to start online are absent from that dataset. A tenants' group has asked to be heard but has no place in the decision meetings. The project document says 'digital by default is modern and fair'. No replacement assistance or appeal route has been agreed.
Work through it
Use paper, your own drawing tool or the notes below. Attempt each step before opening its comparison. Describe a diagram in words when that is more accessible.
1. Complete the four groups of boundary categories in the descriptive 'is' mode.
Produce: Twelve labelled entries, separating case evidence from unknowns.
Compare your work for step 1
Motivation: beneficiary, purpose, measure. The sponsor prioritises administrative savings; whether all applicants benefit is unestablished. Control: decision-maker, controlled resources, decision environment. Council staffing decisions and vendor software control differ; applicants' internet access is not simply a project-controlled resource. Knowledge: expert, relevant expertise, guarantor of success. Analyst/vendor knowledge dominates; current online completion is treated as assurance, but excludes non-starters. Legitimacy: witness for affected people, emancipation or opportunity to challenge, and worldview. The tenants' group is not yet represented; an appeal route is absent; 'modern and fair' is a contested framing. Use 'unknown' where the case does not specify a fact.
2. Write an 'ought' counterpart for each category.
Produce: Twelve proposals with the person or group whose judgement they express.
Compare your work for step 2
One defensible account includes all eligible applicants as intended beneficiaries; successful access to entitlement as purpose; cost, completion, exclusion and effort as measures; explicit council accountability and vendor constraints; assisted access resources; knowledge from applicants and frontline staff; assurance through disaggregated evidence and challenge; an independent voice for affected non-participants; accessible contest and redress; and a worldview in which access is not conditional on digital confidence. These are proposals to discuss, not automatically legitimate claims made on others' behalf.
3. Trace one boundary change into the evaluation.
Produce: A before-and-after judgement with a changed evidence requirement.
Compare your work for step 3
If the beneficiary boundary expands from current online users to all eligible applicants, the online completion rate is no longer sufficient. Count failed starts and people using or needing assistance, and ask about effort and exclusion. An apparently cheaper process may transfer cost or prevent access. The new judgement requires evidence; it is not proof that digital service is necessarily bad.
4. Design a challenge that an affected person can actually use.
Produce: One route to contest the proposal without accepting its framing.
Compare your work for step 4
Invite independently supported evidence from people unable to use the digital route, permit oral or assisted submissions, explain how challenges affect the decision, and provide a route to disagree after a meeting. Do not require a person to complete an online consultation to prove that online access is a barrier. Representation and practical ability to challenge are different questions.
Check the basic distinctions
These checks test the supplied case, not your overall competence. Open answers and model variants still need your judgement.
Repair a defective model or claim
A stakeholder list has twelve names and is labelled 'the twelve CSH questions answered'.
Compare your repair
People are not boundary categories. Examine motivation, control, knowledge and legitimacy in both descriptive and normative modes. A single actor may occupy several roles; a crucial role may have no credible representative.
Try a changed case before looking
The tenants' group gets one seat but cannot alter the agenda or challenge the savings target. Which part of the critique remains open?
Compare the changed case
Witness or representation may have improved, but emancipation and worldview remain contested. Attendance is not sufficient opportunity to question the terms of the decision. Ask whether dissent can alter evidence, criteria or the decision itself.
Review the process, not just the score
All twelve categories are addressed in both is and ought modes.
Evidence, absence and normative proposals are distinguishable.
An affected voice is not silently replaced by an expert or the practitioner.
A boundary change alters a concrete evaluation or action.
The answer includes a practicable route for challenge.
A different model can be defensible when its purpose, assumptions and reasoning are explicit. A contradiction, incorrect unit, invented fact or unacknowledged change of purpose needs repair. Keep both your first attempt and revision.
