Routines are good. It helps takes thinking out of every mundane situation.
Standard Operating Procedures (SOPs) are routine. It’s written down so that the whole unit need not spend an astronomical amount of time thinking and deciding on a routine scenario. To cut time and speed efficiency, learn to have routines and standards. Not everything needs to be customized and personalized. This isn’t an excuse to be lazy.
This is thinking ahead, so time spent thinking can be spent more on stuff that needs thinking. One way to do this is to set a timeline. When the deadline hits, decide on the best possible decision and move on.
