Development team members are located in three different time zones It is difficult to find...

 The project manager should encourage frequent small team meetings with two or three team members to overcome the challenge of finding a suitable time for the daily standup. This is because the daily standup is an important agile practice that helps the team to coordinate their work, share progress, identify impediments, and plan the next steps. However, when the team members are located in different time zones, it can be difficult to schedule a common time that is convenient for everyone. Therefore, the project manager should facilitate smaller and more frequent meetings among the team members who are in the same or adjacent time zones, and ensure that the information is communicated and documented across the whole team. This way, the project manager can maintain the benefits of the daily standup while respecting the team members’ availability and preferences.

The other options are not correct because they do not address the issue of coordination and communication among the team members. Giving up the daily standup and replacing it with a daily report would reduce the interaction and collaboration among the team members, and might lead to delays, misunderstandings, and conflicts. Letting the team members decide themselves if they want to join the meeting would create inconsistency and confusion, and might result in some team members being left out or uninformed. Requiring all team members to join the daily standup regardless of the meeting time would impose an unfair and unrealistic burden on some team members, and might affect their motivation, productivity, and quality of work. References: Agile Practice Guide, section 4.2.1, page 47, PMP Exam Prep, 10th edition, page 100
