Typical outputs

What the client receives.

Outputs are tailored to the decision stage. The objective is a controlled basis that can move into review, procurement, remediation or execution without avoidable rework.

Study report

Decision statement, basis, options, findings, limitations and recommended next actions.

Technical basis

Scope boundaries, assumptions, interfaces, methodology and evidence position.

Commercial support

Cost and schedule basis, work packaging and tender or contracting inputs.

Action plan

Prioritised next steps, ownership, dependencies and information-remediation needs.
