You don't need to be bored with the minutiae of my day, and I'm sure you can substitute things from your own day. But the reason is to force me to look past all the people wanting things right now, and make sure I get the right things done. Distractions and time-eating tasks will pop up everywhere, and competence means your bosses will want to hand you lots more tasks because you Get Things Done. (It also helps me figure out when I need to start load-shedding tasks on subordinates, and when I need to start load-shedding tasks on coworkers or bosses. Surprisingly, when I come back to my boss with the critical-urgent list and say "Which of these following tasks do you want me to drop in order to do your new Project X?", they're usually pretty good about saying "Oh, I'm going to do that myself", or "I think I'll give that to your coworker, instead."
The second tool I use is a process flowchart - a high-level concept of "what do we actually need in order to get the product to the customer?" This proves very valuable at communicating with other departments when I need to borrow their resources, and with knowing when it's a really, really smart idea to crimp my efficiency and lend the asked-for help. (And when it's a really, really smart idea not to, as well.) However, it also means that when one of my subordinates comes up to me and says "Can we try X process change to make my life easier?", I can respond, "If we do X, it's going to hurt Y, which will affect getting the product to the customer." (I don't say 'out the door' because some of the unpopular process changes I have done were to cut down on damage in transit. If the customer isn't happy with the end product, we failed.)
The most important chart I have, though, is the Bacon Theory of Happiness flowchart.
1. Customer wants something, and they want it by the promised delivery date.
2. We get the right product to the right customer, in the shape they expect, at or before the promised time.
3. The customer is happy, and recommends us to their friends.
4. We grow, and get more money to buy bacon. Life is Happy.
5. If we fail to get the right product, or the right customer, or the right time, the customer is unhappy.
6. If the customer is unhappy, they actively recommend against using us.
7. This means less money, so we get laid off and can't afford bacon.
8. Life without bacon is Sad. We don't want to be sad.
9. So, make the customer happy, and enjoy our bacon!
Everyone from the head of the project to the freshest new employee gets the Bacon Theory of Happiness. They may roll their eyes at it and proclaim it hokey, but it does a good job of introducing the concept of "consider everyone downstream of you when you are doing your job, or you will lack bacon and happiness." Sometimes I provide rewards and encourage happiness; sometimes I unfortunately must point out that their causing unhappy customers despite coaching, counseling, and retraining means they will now be one of the unhappy bacon-less people. Either way, we all have a common bacon ground of understanding.
