Earned Value Component

The Earned Value component provides pre-configured presets for the standard earned value metrics used in project cost and schedule performance reporting. Rather than manually combining multiple series in a Combo Chart, the Earned Value component knows the relationships between PV, EV, AC, SPI, CPI, BAC, EAC, and ETC and applies them consistently across presets.

Presets

PresetMetrics shown
EV TrendPV, EV, and AC cumulative lines on a single axis.
PV-EV-ACThe classic three-curve S-curve view (bar or line per series).
CPI-SPICPI and SPI performance indices plotted as lines with a 1.0 reference line.
VarianceSchedule Variance (SV) and Cost Variance (CV) as bars per period.
ForecastEAC, BAC, and ETC lines with an actual cost area. Highlights the forecast completion cost.
ExecutiveSingle KPI summary view: current CPI, SPI, EV%, and EAC in a combined chart-and-card layout.

Data binding

PropertyDescription
Period fieldReporting period or status date dimension.
Planned value (PV)Budgeted cost of work scheduled (BCWS).
Earned value (EV)Budgeted cost of work performed (BCWP).
Actual cost (AC)Actual cost of work performed (ACWP).
BACBudget at completion. Used for EAC and percentage complete calculations.

The component automatically computes derived metrics from the bound fields:

Derived metricFormula
SV (Schedule Variance)EV − PV
CV (Cost Variance)EV − AC
SPI (Schedule Performance Index)EV / PV
CPI (Cost Performance Index)EV / AC
EAC (Estimate at Completion)BAC / CPI
ETC (Estimate to Complete)EAC − AC
TCPI (To-Complete Performance Index)(BAC − EV) / (BAC − AC)
VAC (Variance at Completion)BAC − EAC

Threshold bands

Add coloured threshold bands to CPI/SPI line charts to show performance zones:

PropertyDescription
Green thresholdMinimum CPI/SPI value considered on-track (e.g., 0.95).
Amber thresholdMinimum CPI/SPI value in the warning zone (e.g., 0.80).
Red zoneBelow the amber threshold.
Band opacityTransparency of the zone fills (0–100%).

Multi-level analysis

The component can calculate and display EV metrics at multiple WBS levels simultaneously:

  1. Set the Group by field to a WBS or phase dimension.
  2. The component renders one chart per group value or a side-by-side comparison in a grid layout.
  3. Configure the Comparison level to show how the selected group's performance compares to the project total.

Legend positionTop, bottom, left, right, or hidden.

Good practice

  • Always define the reporting period clearly (monthly or weekly).
  • Place the Earned Value component near a short narrative table showing current CPI, SPI, EAC, and the key variance drivers.
  • Use the Executive preset for senior stakeholder pages and the PV-EV-AC preset for detailed project control reports.
  • When CPI or SPI falls below 0.80, a RAG status flag on a KPI card beside the chart reinforces the message.

  • Cash Flow Curve — time-phased cost and forecast curves
  • KPI Card — CPI/SPI headline values alongside the chart
  • Combo Chart — flexible bar/line for custom EV variations
