9. Evaluate

Many different methods of evaluation are available to assess whether or not the design is effective in delivering the outcomes sought – whether the design has worked. We engage in both qualitative and quantitative evaluation; including evaluation of outputs from the perspective of design (ease and enjoyment of use), market (cost and appeal to targeted users) and crime science (impact of outputs on impact and incidence of crime, which may be measured in a quantitative way that centres on measurable outcomes such as behavioural change or crime rates). The depth of our approach is perhaps more often encountered in what is traditionally called ‘service design’ i.e. the activity of planning and organising people, infrastructure, communication and material components of a service in order to improve its quality, the interaction between [object or] service provider and customers and the customer’s experience. Richard Buchanan’s account of service design is a helpful reference here to fully contextualise this point for those who would like a more in depth explanation.
