Mesydel is a computer tool which aims to faithfully implement the main features of a Delphi survey: collection of data, multiple rounds of questionnaires; address book management; treatment and analysis of qualitative and quantitative data; and dedicated analysis tools.

The Delphi method is one of the most renowned "expert" methods. It is a prospective / foresight method which allows to survey a panel of experts in an iterative way. A typical Delphi survey consists of at least two rounds of questions. After each round, a moderator - or analyst - shall provide a synthesis which is used as a basis for the drafting of the following questionnaire, therefore allowing for a "controlled feedback".

Based on Delphi : Prospective & Participatory Method


Mesydel is a computer tool aiming at faithfully implementing a large subset of the features of a Delphi survey: collection of data, multiple rounds of questionnaires, address book management, treatment and analysis of qualitative and quantitative questions, and dedicated analysis tools.

The Delphi method, one of the most renowned "expert" methods, is a prospective (also called foresight) method, which allows to survey a panel of experts – a recent trend tends to extend the meaning of experts to "experts of use", i.e. any layman/ laywoman which, by his/her very position, has acquired some kind of knowledge on a particular topic – in an iterative way: a typical Delphi survey consists of two rounds at least, with, between each round, a synthesis that is used as a base for the following questionnaire, allowing a "controlled feedback".

One important feature of the method is that it is based on the intuitions and insights of a panel of experts. These experts do not have access to the answers of their peers, which avoids the self-moderation bias: in a situation where such confidentiality were not established, experts could chose to adopt more consensual answers and to express less clear, softer opinions. The Delphi method proved to be efficient in creating "futuribles", i.e. scenarios that are deemed possible, but not certain.

Analysis
The goals of computerization of the Delphi method are numerous: with regard to the collection of answers, it helps reducing the attrition rate. With respect to the analysis of qualitative answers, Mesydel proposes a system of "tagging" which is based on the precepts of the "grounded theory". Quantitative answers, in turn, can be analyzed through charts.
However, in line with the philosophy of never letting the software take decisions in the place of the researcher, analysts are free to use or not the analytical tools that the software makes available.
