When a key team member is unexpectedly absent, it's important for the project manager to collaborate with the rest of the team to assess the impact and reprioritize tasks. This is in line with agile principles, which emphasize team collaboration and self-organization1. The team should collectively decide how to redistribute the workload, possibly by sharing responsibilities or adjusting the iteration's scope. This approach maintains the team's agility and ensures that everyone is on board with the revised plan, fostering a sense of ownership and commitment to the project's success.
