Batching groups similar tasks together to cut down on context switching, which drains focus and time. It works better than techniques like Pomodoro for some people, especially those who lose efficiency jumping between different types of work.
Batching is referring to taking things that you do and doing them in greater quantities at one time. At the very basic level, batching just refers to taking things you have to do instead do them in one big chunk. But in and of itself, putting things into a bigger chunk doesn't really feel all that exciting. How does this have anything to do with process? Many popular productivity methods, such as the Pomodoro method, actually recommend you take big projects and break them down into little chunks. However, for many projects and many types of workers, this is actually going to produce a less efficient outcome than if we took things in bigger chunks. Instead, let's do a bigger batch. So you might work on the first half and then the second half in two larger work sessions rather than four smaller work sessions. And if you are someone that needs to really get into the groove, this will overall make the process more efficient for you. If you have a process where context switching is really time intensive, this could be a great strategy to try out.
