Varying output rate to match demand fluctuations while keeping inventory minimal (Correct answer)
Maintaining a level workforce and building inventory during slow periods
Setting production at the average annual demand rate

Correct answer: Varying output rate to match demand fluctuations while keeping inventory minimal

A chase strategy adjusts production output — through hiring, layoffs, or overtime — to closely match actual demand, minimizing finished goods inventory.

Question 150: What is the role of sales orders in demand management?

They help reduce customer demand.
They provide real-time demand data, which updates forecasts and production plans. (Correct answer)
They focus on managing suppliers.
They help monitor customer satisfaction.

Correct answer: They provide real-time demand data, which updates forecasts and production plans.

Sales orders are critical in demand management because they represent actual, confirmed customer demand. Unlike forecasts, which are predictions, sales orders provide real-time data on what has been sold. This immediate feedback allows businesses to update their short-term forecasts, adjust production schedules, and fine-tune inventory levels, ensuring responsiveness to current market conditions.
