Delphi Technique Essentials

Overview

Delphi Technique: A structured communication method aimed at achieving consensus among experts. It is highly effective in collecting diverse expert opinions remotely, without the need for face-to-face meetings, making it suitable for tackling complex issues.

Historical Context

• Origin: The technique was developed by the RAND Corporation in the 1950s, initially for strategic military forecasting during the Cold War.
• Significance: It provided anonymised expert insights crucial for military decision-making.

Evolution

• Business: Utilised for market forecasting and strategic planning.
• Policy-making: Assists in gathering expert consensus for public policy development.
• Healthcare: Aids in the development of clinical guidelines, such as pandemic response protocols.

Core Principles

• Anonymity: Encourages unbiased input, minimising peer influence.
• Iterative Feedback: Involves continuous refinement of ideas to achieve consensus through surveys.
• Expert Judgement: Leverages diverse expertise for the synthesis of complex data.

Steps Involved in the Delphi Technique

Introduction

Purpose: The objective is to attain consensus on complex issues through expert opinions, commonly applied in public policy and trend forecasting.

Steps Involved in the Delphi Technique

1. Selection of Experts

• Objective: Select credible experts for reliable insights.
• Criteria: Include expertise, diversity, and reputation.
• Bias Management: Essential to derive credible insights.

2. Developing the Questionnaire

• Objective: Gather detailed and truthful expert opinions through clear, anonymous, and open-ended questions.

3. Distribution of Questionnaire

• Use digital platforms for secure submissions and ensure instructional clarity.

4. Collection and Summarisation of Responses

• Conduct systematic data aggregation while maintaining bias-free confidentiality.

5. Iteration and Consensus Building

• Redistribute feedback to refine and strengthen consensus.

6. Finalising Results

• Craft a balanced conclusion with visual aids.
