There are compelling reasons to improve usability and make designs more inclusive, but it can be a challenge to implement these changes in a corporate environment. This paper presents some ways to address this in practice based on over 15 years experience of inclusive design work with businesses. It suggests that a successful persuasive case can be built with three key components: a proof-of-concept prototype, an experience that enables the stakeholders to engage personally with the issues, and quantitative evidence demonstrating the impact of a potential change. These components are illustrated in this paper using a case study that was conducted with Unilever to improve the images used in e-commerce. The ice cream brand, Magnum, is one of Unilever's billion-dollar brands that implemented these changes. During an eight week A/B split test, the new images experienced a sales increase of 24%.
