Facing knowledge evolution in space project: a multi-viewpoint approach

Purpose – The aim of this paper is to provide a conceptual and methodological framework in order to prevent knowledge loss in a long duration space project.Design/methodology/approach – Starting from risk management, the paper considers existing factors that contribute to the success of the mission, such as dependability and safety, and then argues, using a multi‐viewpoint approach, that risk analysis produces knowledge (not simply information or data). Then, the paper describes how the filtering of risky components of a technical documentation is performed. It is based on the confrontation of the vocabulary of the different documents to an ontology of “criticality” built by the authors. The paper also describes how the knowledge evolutions are detected and how the interpretation of these evolutions is carried out.Findings – On a conceptual side, a general model of the design process is presented based on a multi‐viewpoints approach and characterised by a value system. On the practical side, an ontology o...
