Delphi Flashcards
What is Delphi-method?
A social research technique for structuring a group communication process.
What are the generic objectives of a decision conferencing process?
To generate shared understanding of the issues. (not necessarily consensus)
To develop a sense of common purpose (allowing individual differences of optinion)
To agree about the way forward (commitment to the direction, not the individual paths)
What is the two basic principles for an ideal decision conferencing environment?
Everyone to be in direkt eye contact with everyone else
All displays (whiteboards, flip charts…) clearly visible by everyone.
Amphitheater
Who should be at a decision conference?
Key players representing the diversity of perspectives on the issues.
What is the collaborative value Modelling framework?
a method used in very large multi-stakeholders environments. Integratied socio-technical setting that enhances multicriteria decision conferencing with an ex ante Web-Delphi participatory process.
How does a collaborative value Modelling framework work?
- Under unique collaborative learning and constructivist paradigm
- Participants are seen as 1) Experts providing individual expertise, 2) collective learners that construct shared judgemental knowledge.
- Widely informed informed multicriteria evaluation models, and consequently improving their acceptability.
What are the three stages of collaborative value Modelling framework?
1) Process design
2) Web-Delphi
3) Multicriteria decision conferencing
What is the definition of the Delphi method?
Social research technique for structuring a group communication process so that the process is effective in allowing a group of individuals, as a whole, to deal with a complex problem. It focuses on a systematic collection and aggregation of informed judgement from a group of experts in specific questions and issues.
What is the aim of the Delphi method?
Obtain a reliable group opinion using a group of experts. Not a method aimed to produce consessus.
What are the key features of the Delphi method?
Anonymity, iteration, controlled feeback, and statistical aggregation of group response.
What are the 10 types of Delphi models identified by Hasson and Keeney?
Classical Modified Decision Policy Real time/ Consensus conference Web-Delphi Technological Online Argument Disaggregative policy
What are the key aspects to consider while applying Delphi method?
Delphi preparation
Delphi design
Delphi implemetaion
Delphi evaluation
What are the key aspects to consider while applying Delphi method: Preparation?
Indentification and selection of experts
Preperation of evidene and data
Preparation of supporting letters
What is important when identifying and selecting experts in Delphi?
Criteria to include participants.
Homo/hetrogeneity of the panel.
Sample size (Seven as a minimum number)
Sampling strategy
What are the key aspects to consider while applying Delphi method: Design?
First round (explanatory, openended questions or Confirmatory, closed first round)
Total number of rounds (three rounds optimal)
Numbers of questions and response categories (minimum 6 include no comment option)
Feedback
Stopping criteria ( stipulative number of rounds, subjective analysis, level of agreement)
