Identifying baseline food safety training practices for retail delis using the Delphi expert consensus method
2013, Food ControlCitation Excerpt :One method of identifying baseline training materials for new employees is to survey knowledge experts through the Delphi survey technique. The Delphi technique is used to elicit and refine group judgments in order to improve the quality of estimates especially when exact knowledge about an issue is not available (Henson, 1997). The Delphi method was developed by Dalkey and Helmer (1963) and the Rand Corporation and is typically conducted in two or more rounds; where the results of the first round are incorporated in the revised presentation in the second round to allow the responders to reassess their original evaluation (Linstone & Turoff, 1975).

2012, Aquacultural EngineeringCitation Excerpt :The Delphi technique is discussed below. Delphi study – the Delphi process is a standard procedure for eliciting expert opinion (Henson, 1997). Fifty panellists were invited to take part in the Delphi study to identify and select the most relevant food safety hazards (and diseases) occurring in salmon farms in UK.
A Delphi-based approach to developing and validating a farm food safety risk assessment tool by experts
2012, Expert Systems with ApplicationsCitation Excerpt :It could also be used to seek out information which may generate a consensus from the respondent group or to explore underlying assumptions or information leading to different judgements (Hsu & Sandford, 2007; Linstone & Murray, 2002, p. 3). The Delphi technique is essentially a series of structured questionnaires (commonly referred to as rounds) (Henson, 1997) where answers are used as feedback in subsequent sessions or rounds. By providing feedback, Delphi creates interactivity and dialogue but without the pressure of conforming to group’s decisions or from influential respondents (i.e. the group’s position being overly swayed by dogmatic or high-powered individuals).
