Demand forecasting and inventory intelligence

A decision system that combines sales, promotions, seasonality, location, and availability signals to improve replenishment.

01 / Problem statementProposed system · Retail

The operating problem

Static forecasts struggle with promotions, local demand, new products, and supply variability—creating stockouts and excess inventory.

Conditions the system must survive03 operating constraints

Promotions, holidays, stockouts, and new products distort demand history

Forecast error has asymmetric stockout and excess-inventory costs

Planners need overrides for local knowledge and supply constraints

02 / How we approached it

A validation path before production commitment.

The blueprint is organized around four evidence gates. Each stage closes a specific uncertainty before the system moves closer to production.

01Frame

Create store-SKU demand features

Evidence produced

Store-SKU decision map and cost-weighted baseline

02Evaluate

Model promotion and calendar effects

Evidence produced

Leakage-safe backtest across seasons and promotion types

03Engineer

Quantify forecast uncertainty

Evidence produced

Uncertainty and cold-start benchmark for sparse products

04Operationalize

Surface recommended actions with planner overrides

Evidence produced

Planner workspace with override reason and outcome capture

03 / Deployment design

Designed for the environment it must operate in.

The deployment model is proposed from the current operating constraints. Discovery and evaluation would confirm the final infrastructure and integration choices.

Blueprint statusProposed · requires discovery and acceptance testing

Topology

Scheduled cloud forecasting pipelines with a planner-facing exception and recommendation layer.

Integration

Sales, availability, promotion, calendar, supplier, and replenishment data join through time-correct feature pipelines.

Operation

Forecasts refresh by planning cadence; overrides and realized sales feed monitoring and retraining decisions.

04 / Evaluation metrics

What must be measured before the system earns trust.

These metrics establish the baseline and acceptance gates for a future implementation. Numerical targets are set against customer data during discovery.

01Evaluation gate

Weighted forecast error

How it is measured

wMAPE or cost-weighted error by store, SKU, and horizon.

What it decides

Compares models against the current planning baseline.

02Evaluation gate

Forecast bias

How it is measured

Persistent over- or under-forecasting by segment.

What it decides

Reveals systematic inventory risk hidden by average error.

03Evaluation gate

Service-level impact

How it is measured

Stockout exposure and availability on evaluated decisions.

What it decides

Connects model quality to the customer-facing outcome.

04Evaluation gate

Planner value-add

How it is measured

Error before and after overrides with reason codes.

What it decides

Identifies where human judgment improves or degrades the forecast.

05 / Customer perspective

Value has to appear in the customer’s operating day.

What matters in practice

A useful forecast explains the drivers, exposes uncertainty, and keeps planner overrides visible for later learning.

01Observable value signalMore responsive replenishment decisions

02Observable value signalBetter visibility into forecast uncertainty

03Observable value signalReduced manual spreadsheet consolidation

04Observable value signalClearer exception-based planning

06 / Technology context

Tools follow the system—not the other way around.

Final architecture depends on data quality, operating conditions, integrations, risk, and evaluation criteria established during discovery.
