Question 1

What is the relationship between demand planning and supply chain management?

Accepted Answer

Demand planning drives supply chain decisions including procurement, production, inventory, and distribution

Answer

Demand planning is the foundation of supply chain planning — the demand forecast drives purchasing decisions, production scheduling, inventory policies, and distribution planning.

Question 2

What is lead time and why is it important in demand planning?

Accepted Answer

The time between ordering and receiving goods, which affects how far ahead demand must be forecasted

Answer

Lead time directly determines how far in advance demand must be forecasted — longer lead times require longer forecast horizons, which typically means less accuracy.

Question 3

What is demand variability and how is it measured?

Accepted Answer

The degree of fluctuation in demand over time, measured by standard deviation or coefficient of variation

Answer

Demand variability quantifies how much demand fluctuates around its average, measured by standard deviation or coefficient of variation, directly impacting safety stock requirements and service levels.

Question 4

What is the role of demand planning in inventory optimization?

Accepted Answer

It provides the demand forecast that determines optimal inventory levels, reorder points, and safety stock quantities

Answer

Accurate demand forecasts enable precise safety stock calculations, optimal reorder points, and appropriate inventory levels that balance service with investment.

Question 5

What is postponement strategy and how does demand planning support it?

Accepted Answer

Delaying final product configuration until demand signals are clearer, supported by accurate demand planning at the component level

Answer

Postponement delays final product differentiation until customer orders are received, reducing forecast error by forecasting at a more aggregate level where accuracy is higher.
