Most organisational analysis looks at problems in isolation. A programme is late — hire more people. A vendor underperformed — change vendor. Trust is low — publish a new strategy. DHCW has tried all three. None changed the outcome.
When repeated fixes fail, the problem is not the fix. It is the structure regenerating the problem. Systems dynamics, developed by Jay Forrester at MIT and formalised by Donella Meadows in Thinking in Systems, names that structure. It replaces “what broke?” with “what pattern keeps producing breakage?” — and gives a disciplined vocabulary: stocks, flows, feedback loops, delays, and traps.
Root-cause analysis looks for a single upstream failure and stops. Consulting frameworks describe what an organisation should look like. Systems dynamics describes why it looks the way it does.
Stocks — What Accumulates
A stock is anything that accumulates or depletes over time. Money and headcount are stocks. So are trust, institutional knowledge, delivery capability, and political capital — the things that actually determine whether an organisation functions.
Stocks are what a competent board should be watching. They are also what captured governance hides. At DHCW the visible stocks (~£200M annual budget reaching that level by 2025-26, ~£600M cumulative Welsh Government funding over five years, ~1,263 staff, 99.984% availability) look healthy. The invisible stocks (health-board trust, clinician confidence, delivery capability, institutional knowledge) are all depleting. The published record of the visible stocks is itself distorted — 107 sanitisation instances and 237 hiding-intent passages in the deep evidence base — so even the stocks that can be measured arrive softened. Management attention focuses on flows — this quarter’s hiring rate, this quarter’s spend — which is why headcount can grow 80% while delivery capability falls. The flow looks healthy. The stock tells the real story.
The full 18-stock inventory — organised by visibility — lives on the diagnosis page. Each of the eleven feedback loops depletes a specific stock.
Flows — What Changes The Stocks
Flows are the rates at which stocks accumulate or drain. A hiring flow raises headcount. A resignation flow lowers it. A knowledge-transfer flow builds institutional knowledge. A knowledge-loss flow — through attrition, silencing, or loyalty-based promotion — erodes it.
At DHCW the flows are visible and the stocks are not. The hiring flow has run at record rates for three years. The delivery flow — programmes actually shipped to health boards — has barely moved. The knowledge-loss flow accelerates every time an experienced engineer leaves. Measuring flows without measuring the stocks they feed is how a governance system mistakes motion for progress.
Feedback Loops — Reinforcing vs Balancing
A feedback loop is a circular chain of cause and effect in which a change in one element comes back to affect that same element. A reinforcing loop amplifies whatever is happening — when the dynamic is harmful, it becomes a vicious cycle. A balancing loop corrects toward a target, like a thermostat. In a healthy organisation, balancing loops keep reinforcing loops in check.
At DHCW every balancing loop has been captured or neutralised. The diagnosis identifies eleven reinforcing loops in two clusters.
Cluster A — five reinforcing loops of delivery failure. Hiring without delivery, credibility death spiral, annual-funding paralysis, the rebranding escape, vendor-dependency spiral. Any national health IT body under similar constraints would face some version of these.
Cluster B — six reinforcing loops of self-preservation. Manufactured narrative, competence void, loyalty selection, whistleblower suppression, information fortress, oversight obstruction. Cluster B is not structural accident. It is an active engine that intercepts every corrective mechanism before it can reach Cluster A.
Cluster B has an upstream source. Three successive NHS Wales CEOs were drawn from a single health board (ABUHB), via a patronage pipeline that pre-credentialled three DHCW executive directors with UWTSD Professor of Practice titles in December 2020 — four months before DHCW’s founding board meeting. The loops did not emerge gradually. They were imported.
All eleven are documented on the diagnosis page.
Delays — Why Intervention Feels Unrewarding At First
A delay is the time gap between action and consequence. Delays are why sensible interventions look like failures in the short term, and why destructive interventions look like successes. Hire 600 people and expect productivity to rise next quarter; it does not — new hires take 6 to 18 months to become productive. The leader hires 300 more to compensate. That is the classic systems-dynamics overshoot.
Trust is the slowest stock of all. Rebuilding credibility with a health board after a failed programme takes two to five years of consistent delivery — not two to five quarterly updates. Any measurement regime shorter than those delays will declare the right interventions failed and the wrong ones successful. Multi-year measurement is not a preference. It is a precondition for seeing anything at all.
