The Delphi technique is designed specifically for situations where expert opinions are needed to forecast future events or trends. This method involves a structured process of gathering insights from a panel of experts who individually provide their judgments, which are then aggregated and shared with the group for further analysis and refinement. By iterating this process, participants can revise their opinions based on the collective input, ultimately leading to a more informed and consensus-driven forecast.

This technique is particularly valuable in complex scenarios where quantitative data may be limited or unreliable, relying instead on qualitative insights and collective knowledge. It allows for the anonymization of responses, which can help reduce bias and encourage open expression of differing opinions.

In contrast, other methods such as the assessment center focus more on evaluating candidates through their performance in simulations or practical exercises rather than forecasting. The nominal group technique, while a participative approach, involves group discussions and prioritization rather than a structured forecasting methodology like the Delphi technique. Time-series analysis utilizes historical data trends to predict future outcomes, which does not inherently rely on expert evaluations.
