A board-ready memo as it would be attached to Audit Committee papers — anchored to the Orba Enterprise Ltd illustration, with figures and triggers drawn from the underlying diagnostic, CCR run, structural-floor derivation, and classification.
To: Audit Committee From: Group CFO Date: 2 May 2026 Subject: Coordination Capital Assessment — H1 FY2026 Status: Board-ready (Ch. 8 publication, attested) Attestation: Reviewer — Group Internal Audit Director, 2 May 2026 09:42 BST
1. Purpose
To set out the H1 FY2026 measurement of coordination capital across Group Finance & Risk functions, derive the structural floor against which it is governed, allocate the discretionary gap to its drivers, and propose the governance response for H2.
This memo is a measurement and governance instrument, not a cost-saving recommendation. Per the OrbaOS Doctrine, structural coordination is governed not eliminated; architectural debt is redesigned not cut.
2. Headline figures
| Metric | Value | Confidence interval | Band |
|---|---|---|---|
| Coordination Capital Ratio (CCR) | 28.5 % | 27.6 – 29.4 % | Coordination-bound |
| Structural floor | 26.0 % | 24.5 – 27.5 % | — |
| Discretionary gap | 2.5 pp | — | — |
| Discretionary gap (£) | £3.9 m / yr | — | — |
| Diagnostic CDI | 1.85 | — | INTERMEDIATE |
3. What we measured
A measured CCR run was completed weeks 8–11 of H1: stratified sample of 1,200 of 2,800 employees, classified by activity rubric, hour-weighted means within strata, bootstrap 95% confidence interval. Calibration sample (n=30) at week 7. Result independently checked against time-tracker exports and manager attestation.
4. Structural floor
Per the three-layer derivation method (Ch. 7):
- Layer 1 — Obligation baseline: 24.5 % (FCA cycle, audit committee, risk thresholds, mandatory disclosure).
- Layer 2 — Topology and interdependence load: +4.5 % (three-jurisdiction operation, ERP migration vendor, eighteen approval forums).
- Layer 3 — Stability adjustment: −3.0 % (post-merger transition load, time-bounded to Q4 FY26).
- Floor: 26.0 %.
5. Discretionary gap allocation
The 2.5pp gap allocates as follows:
| Bucket | Share | Magnitude |
|---|---|---|
| Transition | 50 % | 1.25 pp |
| Structural | 30 % | 0.75 pp |
| Strategic | 10 % | 0.25 pp |
| Architectural debt | 8 % | 0.20 pp |
| Ungoverned | 2 % | 0.05 pp |
6. Diagnostic — interpretation
The 30-item diagnostic returned an INTERMEDIATE CDI band. Three triggers fired:
- AL+DD. Calendar queues and coupling interact: idle time clusters across units. Behaves like a synchronised blockage surface, not isolated delays.
- AL+RL high. The control chain is thickening after apparent decision points: the system behaves as if post-decision governance is doing remedial work decisions did not remove.
- 3+ high. Stresses are co-activated; multiple guardrails engaged at once, increasing probability of correlated failure under routine load.
These narratives are reproduced verbatim from the doctrine engine. Calibration discipline is preserved; readings are stable across observers.
7. Governance response (proposed)
| Bucket | Response | Owner | Timing |
|---|---|---|---|
| Transition (1.25pp) | Track via drift baseline; expect natural decline | Group COO | through Q4 FY26 |
| Structural (0.75pp) | Migrate into Layer 1 at next floor derivation | Head of Risk | Q3 FY26 |
| Strategic (0.25pp) | Affirm; document strategic justification | Group CFO | this memo |
| Architectural debt (0.20pp) | Redesign — ERP coupling | Group COO + CIO | Q3 FY27 |
| Ungoverned (0.05pp) | Investigate; classify or reduce | Head of Internal Audit | by next assessment |
No headcount or cost-reduction action is recommended on the basis of this measurement.
8. Drift posture
ACTIVE drift baseline registered at 28.5 % CCR with a 5 % threshold (alert if drift > 1.4pp). Cron monitor runs daily; alerts route to Audit Committee secretariat.
9. Continuity and evidence
Twelve evidence items lodged in the Data Room support this assessment. Audit log records every status change to this report (DRAFT → GENERATED → PUBLISHED) with timestamp and actor. The next quarterly assessment will re-test the diagnostic, re-derive the floor, and reconcile drift.
10. Limitations
OrbaOS Instruments is a self-assessment instrument and decision-support platform. CCR and floor are derived from explicit inputs and the formulas published in Methodology. They do not certify regulatory compliance or substitute for audit testing. The Doctrine framework is published at orbaos.com.
