Summing it all up
"So testers, to summarise, if you have a 'QA' column on your task wall, youâ€™re doing it wrong. Go pair with a developer, now. Donâ€™t just wait to bat back a list of bugs to them, go help them avoid having to work on the same thing twice.
Ask which scenarios are important and forget about the ridiculous edge cases for now. Now build it and get real feedback."
