Prototyping is an important part of any development activity since it supports communication and knowledge creation among the members of the developing organization. Although prototyping is well established in the development of physical products, less is known about its use and effect on digital service innovation and development. Since digital technologies today are embedded in almost every level of an organization, from its processes to its offerings, it can be argued that it is crucial for an organization to be able to handle not only digital aspects of prototyping, but also physical and digital aspects simultaneously. This study addresses this need by exploring the impact of digital technology on prototyping, answering the research question “How does digital technology affect the different elements of prototyping?” By taking a comprehensive view on prototypes, implications for development are analyzed and developed based on the complex nature and ontology of digital technology. The result encompasses a set of nine different propositions for digital prototyping which contributes to both academia and the work of practitioners.

Firms seeking radical innovation require development teams to articulate design solutions based on open-ended problems. Such problems have no single answer to the problematical situation, but have several plausible solutions. Although prior studies have highlighted the importance of prototyping or other methodologies, they provide limited guidance toward addressing open-ended problems. We investigate how teams make sense of complex design and development problems in order to benefit innovative endeavors. The results illustrate a team-level concept development model that identifies critical stages, associated activities, and influencing mind-set to explain how engineering teams overcome challenges associated with open-ended problems.

The Create-Build-Test-Learn supports toolbox for engineering concept development motivates not only experimentation, but also instils design thinking in teams. By offering tools and methods for reconstruction of the design challenge, the approach prevents teams to jump into a solution too quickly. When using prototyping as a team resource, reframing of the problem becomes part of the process, ensuring that efforts are put on solving the right problem. The article describes the contents of the toolbox as well as exemplifies how to use it. CBTL has been designed in particular to support SMEs.
