The proposed solution is incorrect because a time group only constrains the possible start times for a booking. In this scenario, a one-hour time group would ensure that jobs can only be scheduled to begin at the top of the hour (e.g., 9:00 AM, 10:00 AM). However, it does not control the duration of the booking. If a work order has an estimated duration of 40 minutes, the system would create a 40-minute booking, leaving the remaining 20 minutes of the hour block available. This violates the requirement that the entire one-hour block must be consumed, preventing engineers from starting a new job within that same block.

A. Yes: This is incorrect. A time group by itself is insufficient as it only dictates valid start times, not the booking's length, failing to block the entire one-hour slot as required.

1. Microsoft Learn. (2023). Set up fulfillment preferences in Universal Resource Scheduling.

Section: Field descriptions for Fulfillment Preferences.

Content: The documentation distinguishes between a Time Group and the Duration field. It states a Time Group is used to "define the specific times a requirement should be scheduled on" (i.e.

the start time). In contrast

the Duration field on the fulfillment preference "allows you to set a duration for the booking. This duration will override the estimated duration on the work order." This confirms that to control the length of the booking and block the full hour

the Duration field must be used

a function not performed by the Time Group.
