Ideally, GanttPRO should use the project baseline, planned schedule, task progress, actual costs and a selected status date to automatically calculate the main EVM values and performance indicators, including Budget at Completion (BAC), Planned Value (PV), Earned Value (EV), Actual Cost (AC), Schedule Variance (SV), Cost Variance (CV), Schedule Performance Index (SPI) and Cost Performance Index (CPI).

It would also be valuable to include forecasting metrics such as Estimate at Completion (EAC), Estimate to Complete (ETC), Variance at Completion (VAC) and To-Complete Performance Index (TCPI).

These indicators should ideally be available both at task/work-package level and aggregated at project level, with the possibility of analysing performance at a selected reporting or status date.

An EVM dashboard would also be extremely useful, including S-curves for PV, EV and AC over time, together with the main cost and schedule performance indicators and forecasts.

This would make GanttPRO much more suitable for structured project performance control, allowing project managers to assess not only whether activities are late or on schedule, but also how much value has actually been earned against the approved baseline, how efficiently time and budget are being used, and what the expected final project performance is likely to be.
