Just about anything and everything can be broken down this way; in fact I struggle to imagine something that is incompatible with this! The author of this piece even fails to give any examples of what he means by something that couldn't be broken down. Any chunk of work that pushes the limits of your brainpower is hard to break down into pieces. For example, coming up with a Mathematical proof. You might be able to break the problem down to some extent, but there's a lot of time spent just thinking, and it's very difficult to predict how long solving a problem will take.
