Abstract

Abstract Exclusion auditing is a process that can quantitatively evaluate the inclusive merit of different products, or alternative design decisions. The results from such an audit can provide prioritised directions for product improvement and support the business case for reducing the capability levels required to use mainstream products. The 1996/97 disability follow-up survey, conducted by the Office of National Statistics, is currently the most comprehensive data source for estimating design exclusion in the UK. The data source is explained in more detail, and a method presented that uses it to estimate the exclusion associated with several tasks that occur in series or parallel, illustrated through worked examples. Having evaluated how many people are excluded, one can investigate why they were excluded, thus generating design insights for how they could be included. Data from the survey is also converted to a series of stylized graphs, which are intended to inspire designers to think about the relationship between the demands required to use a product and the resulting levels of population exclusion.
