ABSTRACT
The idea of user-centered design has grown from debates in interaction and industrial design on product development, which as Hanington argues, is both human-focused and design-centric (Hanington, B. 2003). In general, product designers think carefully about whom users actually were and create products based on their perspectives in which designers assume their responsibility for ensuring users’ capability to employ products as intended after expending a minimum of effort on mastering their use. Today, user-centered design is increasingly concerned with humanizing products through greater contact between designers and end-users. Therefore, user participation must begin as early as possible, ideally before any design has taken place, to develop an adequate perspective on users’ needs and preferences. Recognition of user participation in the development of new products is becoming established as a core feature of progressing design practice. It is evident that new products may require new modes of user
1 INTRODUCTION
In most of interior design projects, the initial description of requirements is almost incomplete due to various difficulties on collecting user’s information. The discovery of design defects late in the development process can result in extremely costly budget overruns. Therefore, trying to make usercentered design approach as the core of design process can be appropriate way to reduce problems caused by insufficient information collected as well as the lack of user involvement. Apparently, user-centered design method could decrease the risk in development process by scheduling frequent releases, which are tested and evaluated by both designers and clients or end-users. Because of relationships among client and designer is always dynamic changing over the course of design processes. Usually, clients have various expectations depending on the nature of their particular projects. Time, budget and project quality are the most important factors to the client. By concerning these three factors, communication then becomes very crucial in design process if the designer is to realize relevant importance of time, money and project quality. Through collecting feedback often, and early in the process, designers are able to constantly adapt design and avoid those unwelcome outcomes at the end of an interior design project.
