You don’t need unit tests. Just write correct code.” “Closing this PEBKAC.” “Looks like another ID-10-T error.” We builders of systems spend a lot of time blaming failures of the systems we build on users of the systems we build. Maybe that’s fine; maybe it’s their fault. If the end users of your web app would just read the ‘Help’ pages, they wouldn’t have to call you with questions so often. If the passengers boarding an airplane would just wait for their zone to be called, the line wouldn’t back up and the plane would leave on time. If the developers you manage would just write code that works, they wouldn’t have to waste all that time on code reviews and unit tests. On the other hand, maybe the systems are inherently flawed, but we don’t notice until users get involved. Maybe we’re not very good at building systems that embrace real people, so instead we build systems that barely tolerate them. How would our system designs change if we started viewing “user errors” as “normative behavior”? How would a system that expected reality from its users be different from one that expects perfection?

Brilliant!

Thanks for the talk!

Very entertaining talk, but with a clear message as well about how developing stuff for experts does not help in most situations. Sometimes even small changes can make things more clear. Thanks for a great opening of PHPDay
