In this scenario, the risk manager is considering a response that could lead to a significant residual risk- excessive additional costs due to overtime. Before proceeding, it is crucial to confirm that the project sponsor is comfortable with the risk appetite for this potential outcome. This step is essential to ensure that the decision to allow overtime aligns with the sponsor's tolerance for additional costs and the overall project risk management strategy. According to the Risk Management Procedure, understanding and aligning with the sponsor's risk appetite is a critical step before implementing risk responses that could impact the project's financials. This approach ensures that all stakeholders are aware of and agree to the potential consequences of the chosen risk response strategy.
