Playbook · Part C Diagnostic Disciplines
What distinguishes a real diagnostic from a structured opinion.
Six disciplines that the engagement protocol depends on. Each addresses a specific failure mode the framework alone does not prevent. Together they constitute the methodology's load-bearing falsifiability standard.
The Anti-Confirmation Gate.
A diagnostic that produces only confirmation of leadership's existing hypothesis adds no information. The anti-confirmation gate is the formal discipline against this failure mode.
Specification
- The diagnostic must produce Output 3 (the binding-constraint finding) and Output 3b (an alternative interpretation that, if correct, would invalidate Output 3).
- Output 3b must specify the disconfirming signal that would surface if the alternative interpretation is correct.
- The engagement deliverable carries both Output 3 and Output 3b as equal-weight artefacts.

The methodology's load-bearing falsifiability standard.
Inter-Analyst Reproducibility.
The diagnostic's measurement claim depends on whether two trained analysts, independently applying the protocol to the same chain, produce comparable delay profiles. If they don't, the measurement is not a measurement.
Specification
- Where engagement scope permits, two analysts measure independently and reconcile after.
- Agreement metrics: Cohen's κ for categorical assignments (state classifications, coupling shapes, status zones); intraclass correlation coefficient (ICC) for continuous t-value differences.
- Where agreement is low, the protocol is the suspect, not the analysts. The protocol gets amended; the engagement's confidence interval widens accordingly.

Threshold Operationalisation.
Every measurement threshold must be operationally defined before measurement begins. What counts as 'signal arrived'? What counts as 'response committed'? What counts as 'implementation observable'? Where these thresholds are left implicit, analyst disagreement masquerades as diagnostic disagreement.
Specification
- Each chain point t₀ through t₄ has a written threshold definition.
- The threshold definition is shared across analysts before measurement.
- The threshold definition is included in the engagement deliverable so consequentiality follow-up can hold the threshold steady.

Signal-Identification & t₀ Anchoring.
The single most-distorted measurement is t₀ — the moment the signal arrived. Without protocol discipline, t₀ drifts retrospectively: a signal the organisation eventually responded to is dated back to when the responder was hired, not when the signal was actually available.
Specification
- t₀ is anchored against observable external artefacts where possible: a competitor announcement, a regulatory filing date, a customer-cohort behaviour shift visible in the organisation's data feed.
- Internal t₀ classes (intra-organisational signals) require their own protocol — the originator's first artefact, the first internal mention with date-stamp, the first explicit recognition.
- t₀ disagreement between analysts is itself diagnostic information about the organisation's Sensing capability.

Within-Engagement Triangulation.
The diagnostic's binding-constraint finding for a single signal-response chain is strengthened when triangulated against at least one independent reference.
Specification
- A parallel signal-response chain at the same organisation (different signal, same operating model).
- A known industry comparator with measured SRD on a similar signal.
- A prior engagement's consequentiality follow-up at the same organisation.
- Single-chain diagnostics carry a stated confidence note acknowledging the absence of triangulation.

Consequentiality Follow-Up.
Already specified in §B.5 as a phase. Re-emphasised here as a discipline: an engagement that does not commit to 6- and 12-month consequentiality follow-up cannot claim SRD-diagnostic status. The follow-up is the methodology's accountability mechanism against the diagnostic confirming itself in absence of contact with reality.
Specification
- Pre-engagement commitment to the follow-up cadence is mandatory.
- At each follow-up, the diagnostic claim is evaluated against the observed outcome.
- Findings that the follow-up disconfirms are amended in the Pattern Library, not quietly retired.
