Select the business case horizon
Choose 3 years or 5 years. The app will automatically adapt cost inputs, calculations, labels, outputs, and Value Realization review periods.

Months to full run-rate
Year 1 benefits are prorated by (12 - months)/12 to reflect go-live, training, and adoption.

Value Realization Review

From project start
Enter the Achieved to date using the same unit as the KPI’s Y3 Target.

How to Use (step-by-step)

1) Pick your number & currency format

Use the header controls to choose 1,234.56 or 1.234,56 and your currency. All inputs and results follow this.

2) Build the Initial Business Case

  1. Select KPIs in the “Initial Business Case” tab. Only the inputs those KPIs need will appear.
  2. Enter the Y3 Target for each KPI (only once). Units are always shown (%, p.p., turns, etc.).
  3. Fill baseline/operational data as prompted (e.g., annual orders, labor $/hr). Fields show required units to avoid confusion.
  4. Costs & finance: Implementation (Y1 only), license & other costs per year (Y1–Y3), discount rate (8–15% typical), and implementation months (benefits in Y1 are prorated).
  5. Click Calculate. You’ll get: annual benefits by KPI, 3-year net value, ROI, NPV, IRR, Payback, and a KPI contribution table.

3) Log Value Realization

  1. Open Value Realization Review.
  2. Select a review period (6, 12, 18, 24, 30, 36 months).
  3. Enter the Achieved to date for each KPI using the same unit as the Y3 Target.
  4. Click Save review. The app computes:
    • Value to Date using trapezoidal integration of achievement fraction (achieved ÷ target) × annual run-rate.
    • Status: On-time/Early if on/above linear plan, otherwise Behind.

4) Dashboard & Reports

The KPI Variance Breakdown lists, for each KPI: 3-year target, Achieved to date, Gap to target (shown in the KPI’s own unit), and Value to Date. Export to CSV or Excel (.xls) for sharing.

“%” is a relative change; “p.p.” means percentage points (absolute). Example: 90% → 95% is +5 p.p.
