The project manager should evaluate the situation and identify ways to compress the schedule without impacting baselines, as this is a strategy for handling delays in project programming activities. According to the PMI website, project delays can occur due to various reasons, such as complexity, resource constraints, poor communication, or risk management issues. When a project is behind schedule or at risk of a critical delay, the project manager should analyze the root causes and the impact of the delay, and determine the best course of action to bring the project back on track. One of the possible actions is to compress the schedule, which is a technique to shorten the project duration without changing the project scope. There are two methods of schedule compression: crashing and fast-tracking. Crashing involves adding or adjusting resources, such as people, equipment, or materials, to critical path activities, to reduce their duration. Fast-tracking involves performing critical path activities in parallel or partially in parallel, to reduce their overall duration. Both methods have advantages and disadvantages, and the project manager should weigh them carefully before applying them. The project manager should also monitor and control the schedule performance, and communicate any changes or updates to the stakeholders1.
The other options, asking the team to work overtime, checking the scope, or submitting a change request, are not the best ways to handle delays in project programming activities. Asking the team to work overtime may not be feasible or effective, as it may increase costs, risks, or rework, and may also demotivate or burn out the team members. Checking the scope may help the project manager to verify if there is scope creep, which is the uncontrolled expansion of the project scope, but it may not address the actual causes or consequences of the delay. Submitting a change request may help the project manager to follow the change management process and seek approval from the project sponsor or the change control board, but it may not be necessary or desirable, as it may imply that the project manager is unable to manage the schedule within the agreed baselines.
