Delphi Technique

Definition

The Delphi Technique is a systematic method for gathering expert opinions and achieving consensus through a series of questionnaires or surveys. This technique is particularly valuable in demand forecasting, as it leverages the knowledge and insights of experts to predict future trends and behaviors. By repeatedly refining responses through rounds of feedback, the Delphi Technique helps eliminate bias and promotes a more accurate forecast based on collective wisdom.

Review Questions

• How does the Delphi Technique facilitate consensus among experts when forecasting demand?
  • The Delphi Technique facilitates consensus by employing a structured approach that gathers expert opinions through multiple rounds of questionnaires. After each round, participants receive a summary of the group's feedback, which allows them to adjust their responses based on new insights. This iterative process continues until a common agreement emerges, reducing individual biases and enhancing the reliability of the final forecast.
• Discuss how anonymity in the Delphi Technique impacts the quality of expert responses during demand forecasting.
  • Anonymity is crucial in the Delphi Technique as it encourages participants to express their true opinions without fear of judgment or influence from others. This leads to more candid and diverse input, as experts can provide honest feedback based on their expertise. The lack of direct interaction reduces the possibility of dominant voices swaying opinions, ultimately improving the quality and depth of insights collected for demand forecasting.
• Evaluate the strengths and limitations of using the Delphi Technique in forecasting demand within logistics management.
  • The strengths of using the Delphi Technique in forecasting demand include its ability to harness expert knowledge and mitigate bias through structured feedback processes. It also allows for flexibility in adjusting forecasts based on evolving expert insights. However, limitations may arise from potential groupthink if experts become overly influenced by others' opinions over multiple rounds. Additionally, selecting the right experts is critical; if they lack relevant experience or knowledge, it can compromise the quality of the forecasts generated.
