**4. Conclusions**

This book chapter discussed the importance of the sub-group of persons living with disabilities, from the more holistic perspective of bi-directional accessibility. It provides better motivation for e-businesses to embrace what we have described as Accessibility experience design, taking user experience to an inclusive level. The study was motivated by the lingering sub-optimal adoption of accessibility practice among e-businesses, despite the existence of drivers. The case for balancing the social and moral requirements for accessibility, with the need for business profit, through the bi-directional accessibility perspective, was established. The case was made for targeting the population of persons with disabilities as a market share, offering them e-business services with accessibility as a package, and therefore accessing the economy they control. To substantiate the argument, there was a need to explore the different types of disabilities, to determine the various types and the proportion of the population which fall under each category. It was necessary to understand in broad and specific terms the strength of the population, who they are, understand the world they live in and therefore empathize with them.

Through the bespoke methodology for the study, appreciable insight has been derived on the dynamics of disabilities and the market implications. This chapter arguably adds a lot of value to the accessibility discourse, introducing new thinking such as AxD and bi-directional accessibility for business services, and introducing new research on accessibility such as [53, 54]. The case for bi-directional accessibility has been articulated and substantiated through analysis of existing reports, and statistical analysis of census data set. Qualitative data from user research was used to construct and analyze the scenarios and realities of the key people concerned, making it possible to empathize with them. Arguably, the information in this chapter should assist relevant people to make the right advocacy and proposal for investment in accessibility. It provides a basis to motivate for the adoption of bidirectional accessibility among e-businesses. The concept of experience design has existed for some time, and many prefixes have been added to it, such as UxD, CxD, etc. However, the notion of AxD, accessibility experience design, invokes a mental model which places accessibility above mere compliance.
