It's always a blast for me to have a discussion with someone as passionate about human users as I am. In speaking with someone today, the topic of target users came up and I mentioned how so many companies or people think they know about their end users but they don't.
When I ask if the website will be for a local, national or global users, the response is to choose but if I ask if they have done any research into the devices, technology, or behavior of these target users, there is none. When a company says "we target global users" they have not checked into internet speed by country, device usage by country, or what areas are not online at all. People forget the differences and lack of opportunities.
Now there are studies on mobile and whether or not revenue increased with a responsive redesign. What fascinates me is that the same incentive is not applied to accessibility design. Companies are racing to get a mobile site to pass Google's test but will continue to ignore accessibility standards, so that they continue to ignore a set of users who could use their website or app but are unable to because it fails WCAG2.0, Section 508, PAS 78, etc. If you were to ask an ecommerce company if they plan on selling in the UK, they will say of course and yet have no idea the UK has strict laws for accessibility and ecommerce.
Some companies will inspect Google analytics looking for clues on user behavior, not understanding that the numbers they see are not an accurate representation of what's happening on their site. It won't occur to them to hire someone to perform user testing to get data from humans instead of bots.
How well do you know your readers/customers and app users?
