Lead users play an integral part in helping engineers to identify latent needs of customers, and this approach has been used in a variety of ways within the design community. However, despite their close resemblance to lead users, do-it-yourself (DIY) practitioners have not been directly examined by the design community. A seven-step framework is presented where the first four steps resemble a typical design process and the remaining steps are relevant for the approach of identifying DIY practitioners as lead users. A case study from the hair care industry is presented to illustrate this framework. This paper establishes a connection between these two groups of customers and demonstrates how the insights of DIY practitioners, which manifest as latent needs for knowledge, can inspire research for the development of new technologies.

Two-dimensional thermal maps of hair samples to which heat was applied by a flat iron from the left edge. (a) Thermal maps of single strands of Type V hair. (b) Thermal maps of single strands of Type I and II hair. (c) Temperature profiles of hair strands indicated by red arrows in (a) and (b). (d) Thermal maps of differently packed bundles of Type V hair. In all thermal maps, red indicates high temperature, and blue indicates low temperature - room temperature in this case.
