A Design Cycle
Figure 52. This diagram is adapted from one within Ergonomics of human-system interaction - Part 210: Human-centered design for interactive systems (BS EN ISO 9241-210:2010). It shows that user-centred design does not follow a strict linear process and illustrates that each human-centred design activity uses outputs from other activities. Design activities continue in an iterative cycle until the solution meets the requirements.
