The investment case, target operating model, transaction documents and governing law control every conclusion.
Material gaps require an owner, corrective action, estimate update, funding response, advice and decision date. Consequences flow through customers, delivery, cash, financing, value, controls and transaction timing. Residual risk remains visible until the cost perimeter is complete, contingencies are funded, benefits are measurable and authorised governing bodies approve the next gate.

33. Quantify productivity and engineering disruption
Estimate management distraction, vacancy, training, dual running, cutover and learning curves.
The technology synergy team should reconcile capacity, time records, transition plan, workforce data and benchmarks. Each conclusion records the accountable owner, source, assessment date, model version, evidence, cash consequence, value effect, dependency, control and unresolved exception. The immediate output is a productivity loss model.
Technology value must be proved through stable service, controlled migration and realised cash after engineering, remediation, dual running, cyber, data, transition and disruption costs. Reviewers test scope, quantities, rates, timing, dependencies, accounting, liquidity and benefit delivery against native records and observed performance. The investment case, target operating model, transaction documents and governing law control every conclusion.
