So I am suggesting you a new scrum but. Written by the book, it could say:
(We use SCRUM, but) (because we are in love with waterfall,) (developers speak first and only then testers in our daily stand-ups)
but it can be masked as:
(We use SCRUM, but) (because testers can not test unless developers develop,) (developers speak first and only then testers in our daily stand-ups)
I've seen this applied, so it's proven to work!
