The purpose of this paper is to develop and illustrate a performance-centered design (PCD) methodology for finding the underlying structure of ill-defined processes and problems. The context for our theoretical exposition is the fuzzy front-end of new product development (NPD). Within the NPD process, front-end concept definition and selection is central to a firm’s innovation capability becaus...

The design of flight deck systems and air traffic control operations often focuses on one particular part of the overall system. In doing so, implicit assumptions are often made about pilot behavior. A recent flight simulator study investigated a proposed air traffic procedure called paired approaches. This study has indicated that a number of the assumptions made by previous studies may be inv...

The ubiquitousness and pervasiveness of mobile devices are likely to change the provision and consumption of healthcare services. In this study we argue that due to the consumerization of Information Technology (IT), Mobile Health IT (MHIT) has a potential for being a critical catalyst for delivering patient centered care. However, relatively little attention has been paid to understand its rol...

The orientation of objects on tables is of fundamental importance for the coordination, communication and proper understanding of content in group work. Similarly, the roles of orientation have to be taken into account when implementing software for multi-touch tabletops. This paper describes a combined approach to help with the orientation of artifacts, composed of both automatic and manual or...

Usability evaluation is essential to user-centred design, yet evaluators who analyse the same usability test sessions have been found to identify substantially different sets of usability problems. We revisit this evaluator effect by having 19 experienced usability professionals analyse videorecorded test sessions with five users. Nine participants analysed moderated sessions; ten participants ...

User-centered approaches to design can guide teams towards an understanding of users and aid teams in better posing design problems. This paper investigates the role of user-centered design approaches in design process and outcome within the context of design team projects. The value of interaction with users is examined at several stages throughout the design process. The influence of user-cen...
