What scenario would result in no available capacity score for a resource?

The correct choice indicates that a complex calendar that doesn’t contain 7 days can lead to no available capacity score for a resource. This can occur because the resource’s availability is measured against a standard workweek, typically assumed to be 5 working days within a 7-day week. If the calendar deviates from this norm, the tools and methodologies used to assess the resource’s capacity may not be able to calculate the available capacity effectively.

In cases where a resource is scheduled ambiguously or over an unusual calendar, metrics such as total hours available for work can be skewed. Consequently, assessment tools might not equate the calendar days to available capacity, leading to a score of "no available capacity."

In contrast, if a resource has too many tasks assigned or is fully booked, this situation indicates a demand for the resource's time that exceeds availability but doesn't inherently confuse the calculation of capacity itself. Similarly, if a resource operates on a flexible schedule, it may still have defined availability measured against tasks, which can result in a calculable capacity score despite variations in scheduling. Thus, these scenarios do not lead to the same ambiguity in capacity calculation as a complex calendar might.
