tasks by switching between them.

When you agree to split up a group of tasks between the people on the team, with
each person taking one task and working on it alone, this is *parallelism*. Each
person on the team can make progress at the exact same time.

With both of these situations, you might have to coordinate between different
tasks. Maybe you *thought* the task that one person was working on was totally
independent from everyone else’s work, but it actually needs something finished
