Recording and Tracking Design Decisions in Interactive System Development

Abstract

Experience economy is prompting the innovation of traditional product design. The design concept - "user-centered design" has received wide recognition. In the face of many professional or non-professional users, the priority of interaction design is to ensure the usability of the interactive product, and then a good user experience of the product. The user interface is an intermediary between human and computer. Users exchange information with the computer via the user interface. The user interface is an important part of a computer system. It is a big part of the software development. The quality of the user interface directly affects the performance of the software. For most users, the user interface is all they know from a product. So for these users, a program with a good interior design but a bad user interface design is a bad program. In this project we investigate different ways of recording design decisions in interactive system development which may allow us to think of the different variants and alternatives that are possible (within a design space) in some formal notation, which then allows us to either reason about their suitability or record the decisions made to understand the impact of decisions and how well they support the given criteria. The goal of this project will involve finding out what the influences are which help drive the design process; considering the effects of individual vs. team design; deciding how and when decisions occur; thinking about useful ways to record decisions and their influences; and investigating the usefulness of the approach through the working examples identified as case studies
