Technical performance measurement compares technical accomplishments to date to the project plan's schedule of technical achievement. Deviation, such as less functionality than planned at a key milestone, can help to forecast the degree of success in achieving the project scope.

The project manager should promote collaboration to help remove the obstacles for the team. This is because collaboration is one of the core values of agile, and it involves working together with the team, the agile coach, the stakeholders, and the organization to find solutions to the problems that hinder the project progress and quality. By promoting collaboration, the project manager can foster a culture of trust, openness, feedback, and learning, which can help the team overcome the obstacles and improve their performance. The project manager can also use various agile techniques, such as retrospectives, backlog refinement, and sprint planning, to facilitate collaboration and identify, prioritize, and resolve the impediments. The project manager can also escalate the issues that are beyond the team's control to the appropriate authority, such as the sponsor or the senior management, and seek their support and guidance.
The other options are not correct because they do not address the issue of collaboration, which is essential for agile projects. Including impediment resolutions during daily standup meetings might be helpful, but it is not enough to solve the obstacles that require more discussion and analysis. Performing a root cause analysis during the standup meetings is not appropriate, as the standup meetings are meant to be brief and focused on the current work and the next steps. Creating a dedicated sprint to solve the obstacles with the team might be a possible option, but it is not the best one, as it might delay the delivery of the project value and increase the project cost and risk.
