Product Owners need to demonstrate to management that their Teams can do better quality work, faster if they can work uninterrupted. The business case for this is strong. Teams can get multiple projects done is less time when they can focus on just one project at a time. The quality of their work also increases. Just like switching from writing, to reading e-mail, to a phone-call interrupts, slows down and wastes an individual Team member’s time, switching from one development project to another wastes Team time (see slide.)
Multitasking is an embedded part of our culture in the digital age. Job descriptions demand it, bosses expect and we brag about our abilities to perform it. It seems like as a society, as multi-tasking has been pushed more and more upon us, we have embraced it. Unfortunately, multi-tasking is wasteful. Don’t do it.
