Time-Scaled Value for Reporting Intervals:
* BCWS (Budgeted Cost of Work Scheduled) is plotted over time to represent the planned expenditure at specific intervals.
* BCWS provides the basis for schedule and cost performance comparisons.
Evaluation of Other Options:
* B: BCWP is used to track actual progress.
* C: SPI is a ratio, not a time-scaled value.
* D: Actual cost of work scheduled is not a standard metric in earned value analysis.
Verification with PSP Guidelines:The PSP Study Guide identifies BCWS as essential for time-scaled earned value analysis (Ref: PSP Study Guide, Chapter 1D: Earned Value Analysis).
