This paper presents a practical description of an analysis and design methodology for complex socio-technical systems. The basis of the approach is a re-elaboration of the unit of analysis originally proposed by Vygotsky. The method focuses on man-artefact interactions in order to inform the design of new artefacts and patterns of interactions. Depending on the required level of design intervention and on the level of structure of the domain the focus is directed either towards the analysis and re-design of weak interactions, or towards the analysis of strong interactions in order to support the design of innovative artefacts and patterns of interaction. Descriptions of the individual steps of the approach, including heuristics for the practical conduct of the analysis and design, are given and illustrated with examples from a range of projects from different domains (railway, clinical, and educational domain).
