Design science

Definitions

• Design sciences related to disciplines that build things.

• “Design is an interdisciplinary and integrative process constituting an intellectual field of thinking and research and a professional field of practice and applied research. Therefore, design research will play one of two roles: (1) the scientific study of the process and the content of design, and (2) the development of methods and tools to enhance the quality of design practice based on the body of knowledge developed by the scientific study” (J. of Design Research Home Page (2006).

• “The design of new products drives to solve problems which solutions are still partial and which tools and methods of assistance are rudimentary. Design is applied in extremely various fields and implies numerous agents during all the process of elaboration and realisation” Intl. J. of Design Sciences & Technology home page, (retrieved 2006)

• “Design is the conscious and intuitive effort to impose meaningful order.” (Papanek, 1971)

Key elements of design-oriented approaches

The Järvinen model

(according to Pertti Järvinen, 2004)

1. Technological rules
   • tell you how to do things and are dependant on other theories (and beliefs)
   • Bunge (quoted by Järvinen:99): "A technological rule: an instruction is defined as a chunk of general knowledge, linking an intervention or artifact with a desired outcome or performance in a certain field of application".
2. Types of outcomes (artifacts, interventions):
   • Constructs (or concept) form the " language " of a domain
   • Models are sets of propositions expressing relationships among constructs
   • Methods are a set of steps to perform a task (guidelines, algorithms)
   • Instantiations are realizations of an artifact in its environment
3. Types of research:
   • Build: Demonstrate feasibility of an artifact or intervention
   • Evaluate: Development of criteria, and assessment of both artifact building and artifact usage

What does this mean ?

• There are 4*2 ways to lead interesting design research.
• Usually, it's the not the artefact (i.e. program or course) you build that is interesting, but something behind it (constructs, models, methods, ...) or around it (conditions, perceptions, usage, ...).

Here is picture that shows some of the relationsships between elements of a design process:

• A researcher can investigate at least on of the dotted lines
• A design rule (technological rule in terms of Järvinnen) is a theory on how to build things. It be input, output or both in a research project. See also design-based research that has become popular in educational technology research.
• Note that the "problem" to "evaluation" sequence is itself a design rule, i.e. a design methodology.
• See instructional design models and instructional design method for designs and methods related to education.

Venable's model

Figure 3 shows how theory building is a central activity related to problem diagnosis, technology invention or design (to solve problems), and technology evaluation. While problem diagnosis and technology evaluation may be undertaken in the empirical domains of natural and particularly social/behavioural sciences, theory building is the necessary link between them all. (Venable 2006: 16)

R.B. Fullers' Design Science Methodology

Sometimes design science is associated with R. Buckminster Fuller's problem solving approach that aims to improve global life-quality (ecology).

The function of what I call design science is to solve problems by introducing into the environment new artifacts, the availability of which will induce their spontaneous employment by humans and thus, coincidentally, cause humans to abandon their previous problem-producing behaviors and devices. For example, when humans have a vital need to cross the roaring rapids of a river, as a design scientist I would design them a bridge, causing them, I am sure, to abandon spontaneously and forever the risking of their lives by trying to swim to the other shore.

Design as a cognitive process

Détienne (2003) likens the design process to the cognitive process model of essay writing presented by Flower and Hayes (1980) with cyclical phases of planning, translating, and revising in the effort to solve a problem.

• planning - retrieving knowledge and possible solutions
• translating - implementation of solutions for given context and medium (e.g.: programming language)
• revising - evaluation and modification of implementation (translation), including a possible redefinition of the problem space (planning)

Fundamental design principles

According to Vita Hinze-Hoare, the four fundamental design principles for "human centered systems" are:

1. Learnability/Familiarity
2. Ergonomics/Human Factors
3. Consistency/Standards
4. Feedback/Robustness

Daniel K. Schneider wonders if this HCI perspective could be applied to all designs...

Types of design research

Van den Akker (1999:3) presents the following not exhaustive list of "natural kinds" and also points out that "the situation is rather confusing":

• Design studies; Design experiments; Design research;
• Development/Developmental research;
• Formative research; Formative inquiry; Formative experiments; Formative

evaluation;

• Action research;
• Engineering research.

After a longer discussion of various design and development activities that happen in in development research, van den Akker (1999:6) suggests to categorize development research within two categories:

1. Formative Research. Research activities performed during the entire development process of a specific intervention, from exploratory studies through (formative and summative) evaluation studies; aimed at optimization of the quality of the intervention as well as testing design principles.
2. Reconstructive Studies. Research activities conducted sometimes during, but oftentimes after the development process of several interventions; focused on the articulation and specification of design principles.

The author also add a Explorative Design Studies category, but since these studies do not aim to generalize they don't qualify as academic research. “These activities, preceding the actual development work, aim at clarifying the design problem-in-context and at generating tentative design ideas. Such explorations can be very valuable in directing the development work.” (van den Akker, 1999:6)

Various issues

Design science in the digital age

“Being digital has begun to affect the way we represent, present, communicate about, and materialize our designs by integrating media in the conceptualization, realization, communication, and production of designs. [...] Furthermore, digitally mediated design is becoming inter-related with concepts of the virtual. Virtual design environments are becoming increasingly immersive, knowledge rich, and intelligent. [...] Digital design thinking is now emerging as the set of phenomena that characterize the way in which the digital designer is beginning to think, employing digital tools and interacting with representational media. His mediated work-place and his electronic community are becoming his expanded e-identity.” (Oxman, 2006: 225)

See also: social computing and virtual environments. There should be an article on collaborative design environments.

The status of theory

Theories are design artefacts. The outcome of research is often formulated as theory; that is, highly universal representations, pretending to be independent of concrete context, practice or situation. From the point of view of design, theories are design artefacts, taking different roles in design; from worldviews, guiding the designer and helping him assess the situations and keep the goals in mind, to tools mediating the achievement of specific results. In this way, the direct outcomes of research mediate design. (Bertelsen, :23).
