Earned Value Was the Gold Standard — POD Made It Better
Earned Value Management was invented in 1967 at NASA. In 60 years, nobody improved it. EVM measures cost. It is blind to schedule. POD fixed that with EarnedScheduleTracker and EarnedValueQuadrant — measuring schedule performance in days, not dollars, for the first time.
How EVM Fails Schedule Performance
A 60-year-old standard that was never designed to catch schedule slippage early enough to act.
SPI calculated from dollars, not time
Cost-based SPI says 0.98 — project looks fine. Time-based reality: 5 days behind.
Schedule slippage hidden in CPI
Budget is green. Nobody sees the schedule is eroding — EVM says you're healthy.
Delay surfaces — now 3 weeks behind
The first visible warning comes far too late. Recovery costs 3x more than prevention.
Owner demands explanation for missed milestone
No data to explain the trajectory. EVM gave no early warning.
EVM Transformed — The Earned Schedule Standard
Watch the classic S-curve evolve: a 4th earned schedule line appears, and the EV Quadrant materializes below — your project position made visible in one glance.
How POD Evolves the Standard
Three additions to the 60-year-old framework that finally make schedule performance measurable in time.
Earned Schedule — Time-Based SPI
POD calculates SPI(t): the time-based Schedule Performance Index. Instead of asking "how much work has been completed?" it asks "how many days of scheduled work have been earned?" — measuring schedule in the unit that matters: time.
EV Quadrant — Four-Quadrant Project Health
The EarnedValueQuadrant plots SPI vs. CPI in a 2x2 matrix. One glance tells you which quadrant your project is in: healthy, time-stressed, budget-stressed, or in distress — and whether you're moving toward or away from Q1.
Earned Schedule Forecast
POD uses earned schedule data to generate time-accurate completion forecasts. Not "you will finish over budget" but "you will finish 9 days late" — with trajectory arrows showing whether that gap is closing or widening.
The Earned Schedule Standard — EVM Evolved for the First Time Since 1967
EarnedScheduleTracker produces SPI(t) and schedule variance in time units. EarnedValueQuadrant plots SPI vs CPI for executive clarity.

Schedule Earned Line
A 4th line added to the classic S-curve shows earned schedule — the moment schedule performance became measurable in time.
Quadrant Trajectory
Arrow on the EV Quadrant shows whether the project is improving (moving toward Q1) or worsening — direction matters as much as position.
SPI(t) vs. SPI($)
Both metrics calculated and displayed side-by-side — showing the gap between cost-based and time-based schedule performance.
Time-at-Completion Forecast
EAC(t) — Estimate at Completion in time units. When will you finish, not how much will you spend.
Historical Accuracy Tracking
POD tracks how accurate its earned schedule forecasts have been — displaying confidence score alongside every prediction.
Variance Decomposition
Schedule variance decomposed by trade, area, and phase — showing exactly where the time is being lost.
“We were using EVM on every project. The numbers always looked fine — until week 14, when the schedule collapsed. POD showed us at week 6 that our SPI(t) was 0.81 even though our SPI was 0.97. The earned schedule line does not lie.”
