From recipes to meals… and dietary regimes: method mixes as key emerging topic in human-centred design

Many argue that a decade-long crisis is crippling methods research in human-centred design (HCD). A recent paper critiques the widespread methods-as-recipe approach and suggests studying methods as part of HCD work; like in cooking, nobody cooks recipes, but they are used to bridge ingredients and meals. This paper extends that metaphor to dietary regimes that govern what meals are pursued. This focus shift expands the scope of relevant issues for methods research, thus creating a demand for open-ended and detailed case studies. Here we conducted a meta-review of five longstanding case studies that highlighted a key topic deserving attention: practitioners’ method mixes should be taken seriously. Single-method use by a project, professional, or company happens rarely (in this data, never). Considering method mixes affects discussions of method validity and reliability. Even more importantly, it opens for consideration how method use in real-life HCD work differs from recipe development and validation.
