Participatory research instils a sense of ownership in the end user and stakeholders. It empowers end users to be more outspoken about their needs and aspirations. Involving all parties at an early stage enables a designer to cost-effectively recruit participants and support for the longer-term design and evaluation of a new product.
The term ‘mixed research methods’ advocated in this chapter are a collection of methods where quantitative (grip strength, anthropometry) and qualitative data (opinions, comments, emotional responses) are collected from within the context of a ‘happening’ or phenomenon, (e.g. a design process).
Case study is a good example of the application of mixed methods research within a New Product development. It is considered by many to be primarily a qualitative recording of an ‘instance’ (observed activities); however, it can have other quantitative metrics, such as task performance outcomes and physical measurements (such as increase co-efficient of friction at a handle interface).
