According to the PMBOK Guide, a sprint retrospective is a meeting held at the end of each sprint to review the work done, identify the lessons learned, and plan the improvements for the next sprint1. The project manager should document the lessons learned and implement the improvements in the next sprint to ensure continuous improvement and customer satisfaction2. The other options are not the next step for the project manager. Facilitating a daily standup is a regular activity during the sprint, not after it3. Organizing a demonstration of the changes is done at the end of each sprint to show the product increment to the customer and stakeholders. Requesting that all team members think of ideas to improve processes is not a specific action, but a general expectation. References:
