Ergonomics of human-system interaction - Processes for enabling, executing and assessing human-centred design within organizationsWhat is this standard about? This document describes the processes and specifies the outcomes by which human centred design (HCD) is carried out within organizations. Human centred design aims to meet requirements for human centred quality throughout the life cycle of interactive systems. The processes are described from the viewpoint of those responsible for the analysis, design and evaluation of the human use of interactive systems. The process
