The artefact as contribution: research through design and design knowledge

A design project ends with something a reader can hold: a prototype, a working system, a set of material samples. The viva will not ask whether the thing exists but what the thing knows.

The second of ten units inherits that choice of type and argues that an artefact is not a contribution on its own. What counts as knowledge is the design reasoning the artefact makes inspectable, and the field still argues over how general that knowledge should be and how it should be documented.

The artefact is the residue of a reasoning process

Zimmerman, Forlizzi and Evenson (2007) proposed research through design as a method for interaction design research, when design had a firm footing in practice and a weak one in research. Designers produce novel integrations of existing knowledge in the attempt to make the right thing, a product that moves the world towards a preferred state. The contribution lies in that integration rather than in the object that results. Because such problems are under-constrained, the value of the work is the judgement exercised in resolving them (Zimmerman, Forlizzi and Evenson, 2007).

The field's own test found the rigour missing

Zimmerman, Stolterman and Forlizzi (2010) interviewed twelve leading HCI design researchers about design research, design theory and research through design. They then examined three historical projects their interviewees repeatedly named. The three were the Maypole project, a two-year European study of memory capture. The Equator project's Drift Table is a coffee table that displays a slowly scrolling aerial view of Britain when someone leans on it. The Emotional Alarm Clock emerged from the Designing Quality in Interaction group's work at Eindhoven. They concluded it might be among the most important contributions design researchers make. The approach had not produced a coherent account of its own rigour, and each project invented its own warrants, so they argued that it should be formalised.

If the contribution is the reasoning, a paper that presents only the artefact has withheld it. Pierce (2014) reviewed the range of design research artefacts in HCI and sorted them into three general types: operational prototypes and products, conceptual and material design studies and experiments, and design proposals. Naming the type is the first step, and showing the work that produced it is the second, because a reader cannot assess unshown making as knowledge.

Documentation is the mechanism, and it has three questions

Documentation is the mechanism, and it has a framework. Bardzell and colleagues (2016) analysed two markedly different research through design cases and built a framework for planning and evaluating documentation around three concerns. The first is the medium that carries the process record. The second is its performativity, that is what the act of recording does to the project as it unfolds. The third is the need to serve both the research and the design aims at once. Their starting claim is that documentation translates design knowledge into broader academic knowledge (Bardzell, Bardzell, Dalsgaard, Gross and Halskov, 2016). What medium carries the record? What does recording it change? Does the record serve the design or only the write-up, and does it say whose bodies and languages the design was made for?

Prototypes and products: the role given to the object decides the claim

If the artefact is evidence rather than the contribution, then what it is evidence of depends on the role it was given. Wensveen and Matthews (2014) set out a typology of the ways designed things appear in design research methods. It separates roles such as the prototype as an experimental component and the prototype as a means of inquiry that records phenomena as an instrument would. The same object can serve either role, and the role determines what the research can claim.

Odom and colleagues (2016) push the argument towards durability. They propose the research product as an extension of the research prototype, because the prototype is not sufficient for work on long-term relationships with technology in everyday life. They specify four qualities: inquiry-driven, finish, fit and independent. They use those qualities to analyse five design research cases run over six years (Odom, Wakkary, Lim, Desjardins, Hengeveld and Banks, 2016). An artefact designed to be lived with rather than tested inherits a different evidential burden.

Material choices and the form of the work are part of the argument

Vallgarda and Fernaeus (2015) propose bricolage, making through what is already to hand both culturally and materially, as an interaction design practice. They argue that it suits tangible and material computing, because it negotiates forms without a hierarchy and stays sensible to an unstable physical world. A material decision can therefore carry an argument: a low-resolution display is a claim about the interaction, not a construction detail.

Wakkary and colleagues (2013) show the form of the artefact doing research work. They combine practice theory with design fiction and analyse two earlier studies, of everyday repair and of green do-it-yourself making, and they describe the practices through materials, competences and meanings. They argue that green practices absorb design fictions in ways that transform them, which makes the fiction a research instrument rather than decoration (Wakkary, Desjardins, Hauser and Maestri, 2013).

Polyphonic assessment replaces the verdict with readings

If the contribution is interpretive, the evaluation cannot be a single verdict. Gaver (2007) proposes polyphonic assessment, in which non-native commentators offer multiple interpretations of a design and the disagreement among readings is treated as a resource for understanding what the design affords. It replaces the question of whether the design worked with what it can be taken to mean. The procedure is concrete. The researcher shows commentators from outside the design's own culture the artefact and asks what they make of it, and the spread of readings, not their agreement, is the result. A panel of young, able-bodied, first-language readers narrows that spread; older, disabled and second-language readers widen it.

A contribution can be a problem rather than an answer

A contribution can also be a problem that did not previously exist. Blevis (2007) defines design as an act of choosing among future ways of being. He develops sustainable interaction design around a rubric that reads a design's material effects through use, reuse and disposal, with principles to guide the field. It is a worked case of a design-led contribution that reframes rather than answers a problem. For a project, the test is whether the artefact opens a question others will pursue.

The contested question: how general should the knowledge be?

The literature divides, and the division is about the standard rather than the object. One position wants research through design to converge on a formal account of the theory it produces. Zimmerman, Stolterman and Forlizzi (2010) call for the field to expand and formalise the approach, so that knowledge generated from design can accumulate. Binder and Redstrom (2006) give the mechanism. Exemplary design research is driven by explicitly formulated design programmes, frames under which a series of design experiments is run. Its results travel because the programme makes one case an example of what could be done and how.

The opposing position holds that the demand for general theory mistakes what design research is. Gaver (2012), in an essay on what should be expected from research through design, argues that the approach is likely to produce theories that are provisional, contingent and aspirational. He argues that the community should resist convergence and standardisation. His constructive proposal is to treat theory as annotation of realised design examples, especially portfolios of related pieces (Gaver, 2012).

What would settle the disagreement is evidence about whether design knowledge travels. The decisive study would take a set of research through design outputs and trace whether later work builds on the concepts, annotations or programmes they offered. It would then test whether the documentation format predicts that uptake. Neither camp offers it.

Read by kind, the two sides do not carry the same evidence. The formalising side rests on interviews with twelve leading design researchers and on three historical projects. The resisting side rests on an essay that reasons from the nature of design theory. Neither tests whether design knowledge travels. While the dispute is open, a project should record its reasoning in the form the documentation framework sets out, and add a programme or annotation that lets a later reader place the case. The strongest objection to this unit's thesis is that an artefact may contribute through the experience of using it rather than through reasoning a reader can inspect, and documentation would then record something other than the contribution.

Where this is heading

The most recent work here points towards comparability rather than towards either pole of the dispute. Kundal and Mangwani (2026) study research through design in a constrained setting, affordable dental care in India. They report that the constraints made tacit design understanding visible as three categories: embodied negotiation of ergonomics, enacted hygiene, and modularity for resilience. Their aim is design knowledge comparable across similarly constrained contexts, a generalisation built from the ground up rather than imposed. Redstrom's (2017) programmes point the same way. The question a candidate inherits is whether those structures will let design knowledge be read by someone who never saw the artefact.
