Abstract
An iterative, user-centered product development process was employed in the design of a floor finish applicator specifically intended for the cramped spaces of healthcare, educational, and retail environments. The inclusion of representative users in the process reduced the risk that the emergent design would not adequately address their needs. Prior to creating a fully-functional prototype, individuals with commercial floor care experience were asked to simulate use during a series of qualitative research studies conducted using mockups and form study models. The fidelity of the models was selected on the basis of what design questions needed to be answered at various points in the development process. By tailoring these physical artifacts so that they addressed only certain features at a time, it was possible to more quickly converge to an appropriate design solution. The emergent design dispenses finish from a 2.5 liter replaceable reservoir, purposefully positioned on its contoured shaft to afford balance and control. Unlike the traditional mop and bucket, which requires training and experience to produce a durable and uniform coat of finish, this applicator naturally promotes the proper body movements without any prior training.
