Share the equipment or project, the problem to solve, the location and required dates. Include drawings, photographs, specifications and any fixed mobilisation milestones.
Review the scope
Confirm the technical requirements, available information, responsibilities, interfaces and acceptance criteria. We identify what needs further definition before committing to delivery.
