Goal – Directed Design Process
Goal –Directed Design Process is a combination techniques of ethnography, stakeholder interviews, market research, detailed user models, scenario-based design, and a core set of interaction principles and patterns. In this process, Cooper puts users at the centre of the design process. Its place huge emphasis on understanding the needs and goals of those users. Its then translating those goals into tasks and activities and ultimately into a more usable end product.
There are a big distinction between goal and tasks. Goal is a motivation for the users and it should be subscribe on what they are trying in order to achieve whereas tasks are the steps involved to help them achieve the goal. The process can be roughly divided into six steps, which are Research, Modeling, Requirements Definition, Framework Definition, Refinement and Development Support. All of these steps were identified by Gillian Crampton Smith and Philip Tabor which is understanding, abstracting, structuring, representing, and detailing at where it follow the five component activities of interaction design.
The first steps of Goal-Directed Design Process is Research. It is between user and the domain. It were employs ethnographic field study techniques which observation and conceptual interviews in order to provide qualitative data about the users or potential users. Indeed, it also carry out a competitor analysis and interview key stakeholders to gather their requirements. After that, when it finished, it will left with a set of instructions which describe how the product could be used.
Next, the second steps is Modeling. It is between users and use context. Modeling is divided into two parts. Part one is define the domain model by building on the workflow pattern from the research stage. While part two is define the user model through the use of personas or the key archetypes which is represent the identifiable groups of the users. Here, the designers employ a variety of methodological tools to synthesize, differentiate, and prioritize personas, exploring different types of goals and mapping personas across ranges of behavior in order to ensure there are no gaps or duplicating.
also consider business goal, technical considerations and brand guidelines at where the context scenarious which really make a big impact to the way of thinking and help to generate a ton of ideas that might not be have considered before that.
The four steps of Goal-Directed Design Process is Framework Definition. It is a
definition of design structure and flow. In this stage, the designers can create the overall product concept and define the basic framework of the product’s behavior, visual design and applicable in the physical form. Plus, it also can create prototypes.
Next, Refinement. Its process similarly to the Framework Definition step, but it is
increasing the focus on detail and implementation. The culmination of the Refinement step is the detailed documentation of the design, a form and behavior specification, delivered in either paper or interactive media as context dictates. This is the stage at where its recommended to create won design documentation at the end of the stage.
The last step of Goal-Directed Design Process is Development Support. It is to
