Design science as nested problem solving

Abstract

Design science emphasizes the connection between knowledge and practice by showing that we can produce scientific knowledge by designing useful things. However, without further guidelines, aspiring design science researchers tend to identify practical problems with knowledge questions, which may lead to methodologically unsound research designs. To solve a practical problem, the real world is changed to suit human purposes, but to solve a knowledge problem, we acquire knowledge about the world without necessarily changing it. In design science, these two kinds of problems are mutually nested, but this nesting should not blind us for the fact that their problem-solving and solution justification methods are different. This paper analyzes the mutual nesting of practical problems and knowledge problems, derives some methodological guidelines from this for design science researchers, and gives an example of a design science project following this problem nesting.

Open Source Software Ecosystems: Towards a Modelling Framework

“…We structure our research in terms of design science since it involves creating new artefacts and acquiring new knowledge, using an engineering cycle as main cycle and internal iterations with engineering activities and the empirical cycle Wieringa [19]. In our project the engineering cycle and the empirical cycle consist of five phases:…”

Towards a unified checklist for empirical research in software engineering: first proposal

“…Our starting point is the engineering cycle (figure 1) discussed more in detail elsewhere [7], [8]. This is a rational choice cycle in which the engineer investigates improvement possibilities (stakeholders and goals, problematic phenomena and their causes), and then designs, implements and evaluates a treatment (figure 1).…”

“…Simon (1996) apresenta o conceito de Design Science, destacando a importância de uma ciência que reflete sobre artefatos para resolver problemas. Nesse contexto, Wieringa (2009) distingue dialeticamente problemas práticos e teóricos, sem, contudo, separá-los. Um problema prático é a diferença que há entre a forma como o mundo é experimentado pelo(a) pesquisador(a) e como ele(a) gostaria que fosse.…”
