Earned Value Management metrics for a project at a point in time.

EVM formulas:

• 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)

Fields

id: String

Unique metric ID

project_id: String

bac: Decimal

Budget at Completion (total baseline budget)

planned_value: Decimal

Planned Value (BCWS — Budgeted Cost of Work Scheduled)

earned_value: Decimal

Earned Value (BCWP — Budgeted Cost of Work Performed)

actual_cost: Decimal

Actual Cost (ACWP — Actual Cost of Work Performed)

schedule_variance: Decimal

Schedule Variance (EV - PV)

cost_variance: Decimal

Cost Variance (EV - AC)

spi: Decimal

Schedule Performance Index (EV / PV)

cpi: Decimal

Cost Performance Index (EV / AC)

eac: Decimal

Estimate at Completion (BAC / CPI)

etc: Decimal

Estimate to Complete (EAC - AC)

tcpi: Decimal

To-Complete Performance Index ((BAC - EV) / (BAC - AC))

Implementations

impl EarnedValueMetric

pub fn compute( id: impl Into<String>, project_id: impl Into<String>, measurement_date: NaiveDate, bac: Decimal, planned_value: Decimal, earned_value: Decimal, actual_cost: Decimal, ) -> Self

Creates a new EVM metric by computing all derived values from the three fundamental inputs: PV, EV, AC, and BAC.

pub fn is_ahead_of_schedule(&self) -> bool

Returns true if the project is ahead of schedule (SPI > 1.0).

pub fn is_under_budget(&self) -> bool

Returns true if the project is under budget (CPI > 1.0).

pub fn is_healthy(&self) -> bool

Returns true if the project is both on schedule and on budget.

pub fn variance_at_completion(&self) -> Decimal

Returns the variance at completion (BAC - EAC).
