Demand Forecast Pro — Plan Inventory Around Expected Sales

Demand planning brief — illustrative simple baseline

Data scope: four supplied fully in-stock weeks, no reported promotions. Average weekly sales = (20+22+18+24)/4 = 21 units. Treat as a simple next-week baseline assumption, not a validated model or guaranteed demand. Four weeks cannot establish seasonality or reliable long-horizon behavior.

Illustrative scenarios, explicitly planning assumptions: downside 18, baseline 21, upside 24 units, based on the observed range. These are not statistical confidence intervals or measured probabilities. A separate stress case would require a defined shock assumption.

Inventory: 15 on hand + 10 confirmed inbound = 25 units before reservations or inbound timing. If all are available before demand occurs, baseline ending balance is 25−21 = 4 units; upside ending balance 1; downside 7. If inbound arrives late, on-hand alone is 6 units below baseline demand.

Decision gates: verify inbound arrival, reserved/backordered units, actual lead time, order constraints, service objective and complete cost context. No safety-stock quantity or reorder point calculated because required variability and policy inputs are missing.

Validation: compare mean and other simple baselines through rolling backtests once sufficient history exists; track forecast bias and error; annotate stockouts, promotions and structural changes. Reforecast when availability, delivery timing or demand evidence changes.

Execution notes: no model fitted, accuracy measured, purchase order placed or supplier contacted. Inventory outcomes are conditional calculations, not commitments.
