In the DFC setting, SD for SI becomes a multi-discipline in which “T-shaped people” can collaborate. (Dijk, p. 110 ,2011 in Stickdorn et al. 2011) T-shaped refers to the metaphor introduced by the design-company IDEO (Kelley, 2000) and describes the intention of having a broad (the top of the T) understanding in various disciplines combined with a deep (the vertical part of the T) knowledge in a specific area. Ideally the combination of a broader general understanding and a specific skill provides a tool enabling valuable collaborations providing viable service concepts and their implementation. (Dijk, 2011,in Stickdorn et al. 2011)
