Question 1

What is the difference between demand planning and demand forecasting?

Accepted Answer

Demand forecasting predicts how much a business will sell. Demand planning is the broader process that turns that forecast into inventory, supplier, and fulfillment decisions, including safety stock, reorder points, and supplier coordination.

Question 2

How does demand planning prevent both stockouts and overstock at the same time?

Accepted Answer

Traditional approaches often treat stockout risk and overstock as a trade-off, holding more buffer to avoid one while risking the other. Modern demand planning, particularly AI-assisted approaches, recalculates safety stock and reorder points continuously per SKU, which reduces both risks simultaneously rather than trading one for the other.

Question 3

How much historical data does a business need before demand planning becomes accurate?

Accepted Answer

At least 12 months is generally recommended, since anything shorter risks missing a full seasonal cycle, which is often the single biggest driver of demand variability for a given category.

Question 4

Is demand planning only necessary for large, high-SKU-count businesses?

Accepted Answer

No. Even a small D2C brand with a handful of SKUs benefits from basic demand planning, since stockouts and overstock carry a proportionally larger financial impact on a smaller revenue base.

Question 5

How often should a demand planning process be reviewed?

Accepted Answer

Quarterly at minimum, though real-time demand sensing should run continuously rather than on a fixed review cycle. A quarterly review is when safety stock formulas, supplier assumptions, and SKU tiering should be reassessed.

Question 6

Can demand planning help specifically with festive-season order spikes in India?

Accepted Answer

Yes. Demand planning that incorporates category-specific seasonal patterns, built from a brand's own historical order data, allows a seller to size festive-period inventory and staffing needs in advance rather than reacting once the spike has already begun.

Question 7

What is the biggest mistake sellers make when starting demand planning?

Accepted Answer

Trying to apply the same level of forecasting rigor across an entire catalog at once. Most sellers get better, faster results by starting with their top 15-20% of SKUs by revenue, since those items generate most sales and benefit the most from accurate demand planning.

Question 8

Does demand planning replace the need for safety stock?

Accepted Answer

No, it complements it. Demand planning determines what an accurate reorder point should be, while safety stock is the buffer that protects against the forecast being wrong. A strong demand planning process actually makes safety stock more efficient, since it reduces how large a buffer is needed to hit a given service level.
