Which qualitative forecasting model relies on the judgments of the most experienced individuals?

• A. Personal Insight
• B. Delphi Method
• C. Customer Survey
• D. Sales Force Estimation

Answer: (A)

The main idea here is using the seasoned judgment of highly experienced individuals to forecast future demand or trends. Personal Insight relies on the deep, tacit knowledge someone with extensive hands-on experience has gained over time, making quick, nuanced predictions when data is scarce or rapidly changing. This approach is valued for tapping intuition and real-world context that numbers alone can miss, and it can be implemented quickly without extensive data collection.

In contrast, other options gather input from groups or specific sources: a Delphi-style process uses a panel of experts over rounds to build consensus; a customer survey collects opinions from customers; and sales force estimation relies on the views of the sales team. While all of those are judgment-based, they don’t center on the forecasts from a single, highly experienced individual, which is why Personal Insight is the best fit for this question.
