Applications

The Delphi technique has been used for meeting several challenges, including [1, 2, 3]:

  • Clarifying and exploring objectives, indicators, criteria, measures and options while avoiding social pressures and psychological distractions;
  • Exploring perceptions associated with the impact of potential options or measures with the aim of obtaining the pros and cons arguments associated with their implementation;
  • Collecting information and experts perceptions to select drivers for building scenarios;
  • Gathering evidence and preferences for weighting criteria and building value functions;
  • Forecasting by exploring what is likely to happen, what may change, and what effects can be anticipated;
  • Planning for resource allocation by exploring stakeholder’s priorities, motivations and values.

Delphi has been applied in a large number of domains [3] including business, economics, finance, health care, sales and strategic planning.
