Multitâches

The lessons a Scrum Master should take from this is to make sure individual Team members are protected from distractions and other Obstacles that would cause them to switch from one Backlog Item to another. Other research has shown that people typically work best in 90-minute bursts followed by some recuperation time. Scrum Masters should make sure to give their Team members ample opportunity to work in blocks of uninterrupted time but also make sure they have opportunities to take care day-to-day assignments that are just a part of having a job like filling out paper work and other management overhead.

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 in 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.
