CPIM Demand Management & Forecasting

Question 1

What is the primary purpose of demand forecasting in inventory management?

Accepted Answer

To determine future inventory requirements

Answer

Demand forecasting is a critical process in inventory management that involves estimating future customer demand for products or services. Its primary purpose is to provide insights into how much inventory will be needed at specific times, allowing businesses to plan production, purchasing, and storage efficiently. Accurate forecasts help prevent stockouts and overstocking, optimizing inventory levels and reducing costs.

Question 2

Which method is considered a qualitative forecasting technique?

Accepted Answer

Delphi method

Answer

Qualitative forecasting techniques rely on expert judgment, intuition, and subjective assessments rather than historical data and mathematical models. The Delphi method is a structured communication technique that uses a panel of experts to make predictions, often through multiple rounds of questionnaires and feedback, to arrive at a consensus forecast. This contrasts with quantitative methods like moving average or exponential smoothing, which use numerical data.

Question 3

What does a high forecast error typically indicate?

Accepted Answer

Forecast needs adjustment or improvement

Answer

A high forecast error indicates a significant discrepancy between the predicted demand and the actual demand. This suggests that the current forecasting method or its parameters are not accurately capturing market trends or underlying demand patterns. Consequently, the forecast model needs to be reviewed, adjusted, or potentially replaced to improve its accuracy and reliability for future planning.

Question 4

Which component is NOT typically part of demand?

Accepted Answer

Stability

Answer

Demand typically comprises several components, including trend (long-term increase or decrease), seasonality (regular patterns tied to time of year), cyclicality (longer-term, irregular patterns related to economic cycles), and randomness (unpredictable fluctuations). Stability, while a desirable characteristic for demand, is not a *component* of demand itself; rather, it describes the absence of significant variation in these components.

Question 5

What is the benefit of collaborative forecasting?

Accepted Answer

Improves forecast accuracy and consensus

Answer

Collaborative forecasting integrates input from various departments like sales, marketing, and production. This diverse perspective helps to reduce individual biases and incorporate more comprehensive market intelligence. The result is a more accurate and widely accepted forecast, fostering consensus across the organization.
