A project manager who makes a company-wide announcement about the successful completion of a project and thanks team members is doing the following:

Celebrating the team’s hard work: This is the correct answer, as the project manager is acknowledging the efforts and contributions of the team members and showing appreciation and recognition for their performance12.

Bringing attention to the project sponsor: This is not the correct answer, as the project manager is not highlighting the role or involvement of the project sponsor, who is the person who provides the resources and authority for the project.

Sharing lessons learned: This is not the correct answer, as the project manager is not discussing the successes, challenges, or best practices of the project, which are part of the lessons learned process.

Collecting feedback: This is not the correct answer, as the project manager is not soliciting any input or opinions from the team members or other stakeholders, which are part of the feedback process.
