A project's design has been completed and approved on time. The construction subcontractor should be mobilizing to start construction but does not have the necessary materials in place, causing a delaying in the project. The risk register only contains risks for the design phase of the project. What should the project manager have done differently? Executed the Monte Carlo sensitivity analysis prior to mobilization Added generic construction risks to the risk register before construction began Performed risk identification exercises for the full lifecycle of the project Reviewed the assumptions/exclusions register in the project charter
