Nancy reports that $1.05 worth of work has been accomplished for every $1 worth of scheduled work. Where did she get this information?

The situation described indicates that Nancy is utilizing a performance measurement method related to the value of work performed compared to the value of work planned. The information she reports, specifically that $1.05 worth of work has been accomplished for every $1 worth of scheduled work, relates to the assessment of the efficiency of project work against the planned schedule.

This metric is represented as the Schedule Performance Index (SPI), which is calculated using the formula:

SPI = Earned Value (EV) / Planned Value (PV)

In this case, a SPI greater than 1 (in this instance, 1.05) signifies that the project is ahead of schedule, indicating that for every dollar of planned work, more work (value) has been accomplished. This metric is crucial for project managers as it helps them gauge if the project is progressing as scheduled and plan necessary adjustments.

The other options do not directly refer to the comparison of earned and planned value in this specific way. The Cost Performance Index, for instance, focuses on cost efficiency rather than schedule; Schedule Variance provides an absolute measure rather than an index; and Earned Value itself is a broader measure that encompasses both cost and schedule performance. Thus, the emphasis on measuring schedule performance specifically aligns perfectly with the
