By Paul Johannesson, Erik Perjons

This ebook is an introductory textual content on layout technology, meant to help either graduate scholars and researchers in structuring, project and providing layout technology paintings. It builds on proven layout technology equipment in addition to contemporary paintings on proposing layout technological know-how reviews and moral rules for layout technology, and in addition deals novel tools for visualizing the consequences, either within the kind of strategy diagrams and during a canvas layout. whereas the e-book doesn't presume any earlier wisdom of layout technological know-how, it presents readers with an intensive knowing of the topic and allows them to delve into a lot deeper element, due to vast sections on additional reading.

Design technological know-how in details structures and expertise goals to create novel artifacts within the kind of types, equipment, and platforms that aid humans in constructing, utilizing and protecting IT suggestions. This paintings makes a speciality of layout technological know-how as utilized to info platforms and expertise, however it additionally contains examples from, and views of, different fields of human practice.

Chapter 1 offers an summary of layout technology and descriptions its ties with empirical examine. bankruptcy 2 discusses a number of the kinds and kinds of wisdom that may be used and produced by means of layout technological know-how study, whereas bankruptcy three provides a short assessment of universal empirical learn thoughts and techniques. bankruptcy four introduces a methodological framework for assisting researchers in doing layout technological know-how study in addition to in providing their effects. This framework comprises 5 middle actions, that are defined intimately in Chapters five to nine. bankruptcy 10 discusses the right way to converse layout technology effects, whereas bankruptcy eleven compares the proposed methodological framework with equipment for structures improvement and indicates how they are often mixed. bankruptcy 12 discusses how layout technology pertains to learn paradigms, specifically to positivism and interpretivism. finally, bankruptcy thirteen discusses moral matters and rules for layout technological know-how research.

1 Constructs, Models, Methods, and Instantiations Within design science, it has become well established to identify four types of artefacts: constructs, models, methods, and instantiations. Constructs are terms, notations, definitions, and concepts that are needed for formulating problems and their possible solutions. Constructs do not make any statements about the world, but they make it possible to speak about it, so it can be understood and changed. Thus, constructs are definitional knowledge.

In other words, explicit knowledge facilitates reflection and innovation. One of the main purposes of design science is to support designers and researchers in making design knowledge explicit, thereby moving design from craft to science. Design science offers this support by clarifying the principles behind design and by providing methods for creating artefacts as well as explicit knowledge about them. However, not all of the knowledge embedded in an artefact can be made explicit, and therefore, the artefact itself is a vital result of any design science project.

An example of a theory is Agency Theory, which is concerned with problems about conflicts between people with different interests in the same assets (Eisenhardt 1989). For example, the owners of a company (principals) may have different interests than its managers (agents of the principals). Basic constructs in Agency Theory include principal, agent, risk, goal, contract, and monitoring. These constructs are used in formulating descriptive statements, such as “Often agents do not act in the interest of their principals”.
