Viable System Model: diagnose functions and channels

Choose a recursion, identify operational units, and test management functions without turning the VSM into an organisation chart.

What this exercise can and cannot establish

A basic organisational diagnosis. Functions can be distributed or combined in people and groups. The exercise does not establish that every multi-agency network has a single legitimate metasystem.

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: Neighbourhood Advice Cooperative runs North, Central and South advice centres. Each serves local residents, organises its own advisers and decides ordinary cases. They share specialist interpreters and sometimes double-book them. A cooperative operations group negotiates budgets and capacity with centre leads. A quality reviewer periodically observes cases directly, with an agreed learning remit. A small planning group studies changing resident needs and technology, but its reports rarely reach operations. The elected board sets identity and purpose and settles major policy disputes. An urgent safeguarding concern currently travels through three monthly reporting meetings.

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. 1. State the focal system and one level above and below it.

    Produce: A recursion statement and three candidate operational units.

    Compare your work for step 1

    Focal system: the advice cooperative as a whole. Candidate System 1 units: the three centres, each with an operation, local management and a relevant environment. Within a centre, case teams may form the next level if they genuinely carry primary activity with appropriate management. A wider partnership is only a candidate level above: do not assert that it governs the cooperative without evidence and legitimacy.

  2. 2. Map the case evidence to Systems 1-5 and 3*.

    Produce: A function-evidence table, leaving unknowns visible.

    Compare your work for step 2

    System 1: centres delivering advice in their local environments. System 2: arrangements damping interference between centres, such as interpreter booking protocols; the double-booking suggests a gap. System 3: the operations group's resource bargains, synergy and internal regulation. System 3*: the agreed direct sampling of operational reality, distinct from routine reports. System 4: the planning group's outside-and-future intelligence. System 5: identity, policy and balancing present and future through the elected board. These are functions evidenced by activities, not job titles.

  3. 3. Diagnose two channel failures.

    Produce: Two hypotheses, each with a verification question.

    Compare your work for step 3

    The System 3/4 dialogue may be weak: ask how a recent external change altered an operational decision, and how operational experience revised a future proposal. Urgent safeguarding signals are too slow for their purpose: trace a concern's actual escalation and response time. A System 2 booking weakness is another defensible hypothesis. A missing line in your diagram alone is not proof that the function is absent.

  4. 4. Design a correction that preserves local autonomy.

    Produce: One bounded change and a check for over-centralisation.

    Compare your work for step 4

    Give centres a shared interpreter availability view and agreed conflict-resolution protocol, while leaving normal case decisions local. Establish a direct urgent escalation route with named response responsibility. For future adaptation, create a recurring 3/4 conversation using both demand evidence and operational constraints. Check whether the new arrangement removes local discretion that does not need to be centralised.

  5. 5. Test the diagnosis with operational evidence.

    Produce: A short sampling plan.

    Compare your work for step 5

    Trace an ordinary case, a cross-centre resource conflict, a future-driven change and an urgent exception. Ask the people doing the work how information and authority actually move. Distinguish formal policy from observed practice. Use direct observation with a legitimate remit, not covert inspection presented as neutral learning.

Check the case functions

Match activities, not people or job grades. This checks the supplied case; other organisations require evidence of what each activity does.

Check the basic distinctions

These checks test the supplied case, not your overall competence. Open answers and model variants still need your judgement.

1. Which is the strongest System 2 example in this case?

Answer and reasoning 1

A shared interpreter scheduling protocol

The protocol reduces interference among operational units. Identity is a System 5 concern; outside-and-future intelligence is System 4.

2. What distinguishes System 3* from routine System 3 reports?

Answer and reasoning 2

It provides a direct, agreed check on operational reality

The distinction is the information channel and function, not rank or the word 'audit'. Its remit and effect on trust still matter.

3. Must the three centres have identical local arrangements to be System 1 units?

Answer and reasoning 3

No, they need viable local responses within the cooperative's identity and constraints

Different environments may require different response variety. Coherence does not require identical local operations.

Repair a defective model or claim

The chief executive is labelled S5, all middle managers S2, every worker S1, and the outside world is omitted.
Compare your repair

Choose the recursion and primary activities first. Identify actual functions, environments and channels. One person may perform several functions; a worker may exercise local intelligence and policy. An organisational rank is not a VSM system number.

Try a changed case before looking

An autonomous helpline is added with its own users, case decisions and local management. Is it necessarily System 2 because it connects centres?

Compare the changed case

No. It may be another System 1 unit if advice delivery is a primary activity at the chosen recursion. Some of its activities could also support coordination. Determine function, operational autonomy and environment rather than classifying it by the word 'helpline'.

Review the process, not just the score

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.

External resources and their limits

The complete original case above is free. Links below distinguish exercises from explanations, recordings, software and paid study. Reading a page or drawing in a tool is not itself a model check.

Metaphorum: VSM mapping and editable diagrams

Free | Diagram resources

Use the editable diagrams after identifying your focal system, operational units and channels. A completed template is not evidence that the diagnosis is sound.

What was checked, and what was not

Diagram links and Jon Walker's editing instructions inspected. Templates are not an answer validator.
