It is common to be multi-tasking in the workplace whether one likes it or not. Even if one is working on business-as-usual tasks, inevitably ad hoc tasks have a way of turning up and demands one’s attention. Decreasing the amount of ‘working memory’ that a task requires can allow one to multitask effectively. That’s where habits can help: Habits allow actions to be retrieved from muscle memory upon triggers and performed with little cognitive effort. If you’re working in an environment that requires multitasking, think about the relatively routine sort of tasks that you can convert into habits. Then be sure to give sufficient time to practice those triggers.
