Human centered design (HCD) and software development process

Abstract

ISO TC159 deals with Human Factors and Ergonomics Standards. They have four sub-committees (SCs), they are, SC1 "General ergonomic principles", SC3 "Anthropometry and biomechanics", SC4 "Ergonomics of human system interaction" and SC5 "Ergonomics of physical environment" and over 100 standards has been published. It is important that ISO is useful for industrial area. But it is also important to be supported by academic area.The theme and concept of ISO TC159/SC4 are as follows:1.Human centered design (HCD) / usability: process and concept, format related software engineering2.Interaction: interaction principles, principles of presentation of information3.Display/ image: hardware characteristics and image safety4.Environment: desk and chair in HCI, object about physical environment and things about work style.5.Control panel: design for central control room in a large size control systemIn these, most of standards Almost of them have been standardized as ISO9241 series in ergonomics standards.These five themes are much important for social system from the viewpoint of ergonomics. Especially, HCD is necessary for improving software usability. There are four activities in HCD, they are, clarify context of use, “Understand and specify the context of use”, “specify the user requirements”, “produce design solutions to meet these requirements”, “evaluate the designs against requirements”. As examples of outcome of HCD activities, format related software engineering, i.e., “Common Industry Format for usability related information (CIF)” are prepared.This paper shows the result of systematization relationship among standardization about interaction, presentation of information, HCD and software quality, especially software quality. To systematize these relations, it can be clarified that the relationship among process model, process assessment model, software quality and HCD.
