Abstract [en]

One of the most common problems we face as usability professionals today is that of not being involved early enough, or not having the desired impact on the systems development. In this paper we propose that one reason for this may be that we in client-supplier relations in contract- and in-house development unconsciously only seek solutions from a supplier perspective, where “early involvement” marks the beginning of the supplier’s engagement. In this paper we propose that usage-centered design may instead be viewed as a tool for clients to define what system to purchase, and what requirements that are appropriate for both the business as a whole, and for the individual users. We present a model how to work with User-Centered Design (UCD) in procurement and describe two case studies that followed this work model. The results from the case studies suggest that this approach effectively deals with issues of early involvement and integration of user requirements in systems development. The clients in the case studies valued the UCD work and based their forthcoming systems development on it. Apart from integrating a UCD perspective before a contract for the development was signed, a number of other benefits were accomplished, including an integration of business and user requirements and a facilitated communication among stakeholders. We discuss some of the preconditions for this approach to be successful, based on experiences from the two case studies. This approach requires us to reconsider the role of UCD in systems development. We believe a change will come, but slowly, since it challenges established conceptions in UCD.

Abstract [en]

Usability professionals seldom get a chance to actually do their job. Instead, they have to argue that usability is something important that should be attended to. This was the initial problem that motivated this thesis. In spite decenniums of evolution within HCI this problem is still highly relevant, and existing approaches to solve it yet have to prove their effectiveness. When approaches to integrate HCI into systems development have been discussed, there has seldom been a discussion about how a given approach may be more or less useful in different development contexts. Nor has there been much discussion about how HCI activities relates to the overall procurement-development process. One reason for this may be that existing approaches to HCI integration are suited primarily for product development and, to some extent, to in-house development. At least these contexts are most common in existing case studies.

In this thesis, I focus on the problem of HCI integration in contract development. This context poses particular challenges, mainly because two parties with different goals are involved – the procurer and the supplier. They regulate business relations and responsibilities via the contract. In both existing practice and in research the user-centred design (UCD) process has, at least implicitly, been assumed to belong to the supplier side. It is the suppliers, i.e. consultancy firms, that have employed usability professionals and that have tried to integrate HCI into their development processes. By taking a procurement perspective instead, I question this assumption.

I present three case studies that start with a survey of common problems in current procurement practice and end with trying out an approach to work with UCD in systems acquisition. While my interest initially concerned successful HCI integration, I also discuss how the suggested approach deals with several existing problems that procurers face. In particular, the approach links abstract business goals that any systems acquisition starts of with, to detailed systems requirements that it aims at defining. This facilitates for procurers to focus on the goals that the future system should help enable and linking these goals to the requirement specification that the contract is based on.
