Demand Planning
A managed process for forecasting future demand and planning purchases accordingly. Differs from demand forecasting by also including: planned promotions, seasonality, new launches, and promotional events.
In practice
Demand planning is 'forecast + action.' It's not just about predicting — it's about deciding what to order, when, how much, and from whom. A store that sells on Black Friday but didn't plan demand faces a stockout at peak. A store that planned sells right down to the last unit.
Common misconception
'Demand planning requires a complex spreadsheet.' No. Basic demand planning: promotional calendar + historical sales + lead time + safety stock = a reorder schedule. Excel is enough for stores up to $1.5M annually.
How to fix it
Demand planning inaccurate? (1) Factor planned events — Black Friday, holidays, launches — into the forecast, (2) Compare forecast vs. actual every month and learn from the gaps, (3) Coordinate with marketing — a campaign means a demand spike, (4) Add a 15-20% buffer for major events.
Example
Holiday goods store: Black Friday 2023 forecast 800 units. Actual: 1,340 units (a stockout on day 2). In 2024: demand planning including social-media trend data + a 25% buffer = 1,100 units. Stock lasted through the entire Black Friday period.
Priority
Hold a quarterly demand-planning session: what's planned for next quarter? Promotions? Launches? Seasons? Translate that into quantities and reorder dates. A promotional calendar is the simplest demand-planning tool.
