When selecting the schedule mode in Project details, what are the two default options?

The default options for schedule mode in Project details are designed to help project managers establish timelines effectively. The completion date and start date are integral to planning as they mark the beginning and the anticipated end of the project. The start date indicates when work on the project should commence, providing a baseline for resource allocation and task scheduling. The completion date, on the other hand, outlines when the project is intended to be finished, which is critical for stakeholders to assess the project's delivery and overall timeline.

By using these two dates, project managers can effectively plan and monitor progress, ensuring that all tasks align with the overall project goals. This dual focus on both starting and completing the project allows teams to organize their workflows and deadlines in a structured manner, which is fundamental in project management.

Other combinations don't align with the typical setup in project scheduling, as must-finish on and must-start by options add constraints that may not be necessary during the initial planning phase, making them less appropriate as default selections for standard project scheduling.
