“Put your user in the middle of your flow. Make them press an extra button, make them provide some inputs, let them be part of the service-providing, rather than a bystander to it. If they are part of the flow, they have a better vantage point to see what’s going on.
[…] If your user has to wonder, “So, did it work?” you’ve failed. Walk people through using your product like a magician leads the audience through an illusion.”
