One important aspect, also highlighted by others, is that for the long term you actually _don't_ want to focus solely on the immediate task you're solving. Sure, short term the tasks are getting done quicker, but since the end goal typically is implementing a full coherent solution you _have_ to step back and take a look at a bigger picture every now and then. Typically you won't be allocated specific time when to do this, so this "take a bird's eye view" part has to be incorporated into day-to-day work instead. It's also typically easier to notice bigger issues while you're already in the trenches, compared to doing "cleanup" separately "later".
