Creation of a shared vision within a scientific community working on dengue disease


The non-governmental organization Partnership for Dengue Control brings together a large community of dengue specialists. Before calling on Mesydel, the NGO organized meetings several times a year, representing a significant cost in transportation and logistics. The results were disappointing in terms of reaching a consensus, for example on scientific definitions. Partnership for Dengue Control called on Mesydel to carry out a constructive dialogue among the scientific community:

  • Complete organization of the participatory approach with stakeholders in the medical sector (questionnaires, invitations, data collection, recalls, analyzes, etc.)
  • Scientific consensus on definitions of dengue and its severity parameters
  • Co-construction of a tool for dialogue and follow-up of patients with dengue fever

Diagnosis and anticipation of changes of usage in geographic information


Geographic information, whether on paper or computerized, is increasingly used by territorial actors, public and private organizations. In this context, the Public Service of Wallonia needed to: 1) reconcile the tools and data produced with user expectations and needs; 2) reach an agreement to standardize the production of geographic information to be able to compare and integrate dipersed data. Mesydel was used for a two-round survey bringing together companies, public organizations, municipalities and IOPs.

  • Anticipation and decision support in the context of a fast-growing sector
  • Harmonization and standardization of methods among a wide range of actors
  • Awareness of Walloon society on the strengths of geomatics
  • Probe the participatory dimension of geomatics approaches

Happy Mum: participatory design of a website dedicated to young parents


The objective of this project was to co-construct the design of a website dedicated to post-natal issues. The difficulty was to create a shared vision amongst parents and health professionals altogether.

  • Creation of a shared vision of the most effective tools for coping with post-natal depression;
  • Identification of the most relevant themes;
  • Co-creation of effective categories for the creation of an information website for families.

  • Creation of a shared vision amongst a very wide range of interlocutors : textile experts, health professionals, patients;
  • Agreement on many optimal specifications: decision-making process based on consent of all;
  • Participatory design that gave rise to the design of a portable textile device.
