Solid = stored actuals (Historical KPI trend data). Dashed = deterministic projections in the shaded period. Band = ±1σ of historical residuals around the no-action line, widening with horizon. Direction of good: higher.

Source data, assumptions, methodology & limitations
Source data
- Telecom KPI data (current period, target, prior)
- Historical KPI trend data (monthly history Apr–Sep 2026)
Assumptions
- Run-rate baseline: holds the latest stored actual flat.
- No action: continues the 6-month stored trend (+0.41 per month).
- Recommended action: reverses the trend at the same monthly rate (no stored target).
Methodology
- Least-squares straight line through 6 stored months (slope +0.409 per month).
- Residual standard deviation σ = 0.082; spread = σ × √(months ahead).
- Identical arithmetic feeds Decision Journey Stage 5 — Predict.
Limitations
- Forecasts are straight-line projections of six stored months; they ignore seasonality, shocks and interactions between measures.
- Many KPIs have no stored target; where absent, the recommended path reverses the trend at the same monthly rate.
- No downside scenario is stored for any journey; downside coverage is shown as a gap rather than invented.
