qa * a more realistic view * two disciplines with their own lifecycle * but as silos, really? * epiphany?

“where the team ‘tries to go the distance as a
unit, passing the ball back and forth’” Hirotaka Takeuchi, Ikujiro Nonaka New New Product Development Game, ’86 * full stack ownership (awareness) * cross-functional team
development affects ops
development affects ops
design install develop monitor test patch .... development operations +
awareness we must be aware of the other teams and
disciplines around us in order to...
patience ...have patience for us and for them to...
insight * ...gain insight into our respective discipline, skill sets
and challenges... * see each others work * be close (whatever that means)
understanding ...so that we can come to a better understanding
about all parts of the equation
