Day 53: An Engineering Mindset

I have spoken out many times about how much I dislike software developers granting themselves titles that include the terms “engineer” or “architect” in them. Those are titles that are earned through years of hard study and certification, just like doctors and lawyers.

Software development is not engineering. If I want to build a vaulted ceiling in my home, there are tables of the properties of materials that give the acceptable spans for any given size of component. If I have a 20-foot span, I can look at those tables and determine what I would need with steel beams, engineered wood beams, or plain 2×10 lumber.

Each of these engineered wood beams has a known maximum span.

There’s no need to debug this; these are known values, along with gravity, weight, and all the other things that go into building design. And you could use a table for materials from 100 years ago, and it would still work today. Knowing how to apply these values in the structure behind the design of buildings takes years of study before one can legally call themselves an architect or an engineer.

The most apt term I’ve heard for a software developer is “gardener”. It’s accurate, as gardens take up-front planning, and like software, they need to be maintained. Both also have their share of bugs!

So while I won’t call myself an engineer, I do have an engineering mindset. What I mean by that is I strive to be methodical about things like program structure, testing, code review, version control, and the like. I enjoy working with teams who are like-minded in that regard.

An engineering mindset isn’t limited to software development, though. I find I do that with every task I do. Take washing dishes, for example. We don’t have a dishwasher, so they all need to be washed by hand. Nor do we have a drainboard, so they have to go on a towel by the sink. I don’t just wash them in the order that they are piled in the sink; instead, I re-arrange them so that they are stacked in the order to be washed in the left sink basin, with the right sink basin empty. Why? Because the drying area is on the right, and this makes for a neat left-to-right flow. First the flat dishes get washed and placed in the right sink. They are then rinsed off, then placed vertically leaning against the wall to help them dry evenly and quickly. Then the bowls and other things with depth are washed, with the eventual placement in the drying area determining the order. Finally the small things like utensils are washed and placed in any available spot left on the towel. This allows the most efficient use of the limited drying area while still allowing things to dry fully.

The other thing I try to optimize for is to minimize the use of hot water. I’ve come up with some routines for group wetting and rinsing that has cut the amount of hot water usage. I’ve even played around with how an item is handled while being rinsed in order to get the most efficient rinsing of all surfaces.

I have been developing this process over the 4 years since we moved into this small house, and I believe I have it down to as efficient a flow as possible. I’ve mentioned this to people, and their reaction is along the lines of “wow, you’re pretty OCD!”. But this isn’t anything like OCD: people who suffer from that condition say that they are perfectly aware that their actions are silly or even harmful, but are unable to stop doing them. I choose every one of these steps because it makes sense. If someone were to show me an even better way to do it, I’d switch in an instant.

That’s an engineering mindset: taking a process, even one as mundane as washing dishes, and always thinking of ways to optimize it. It doesn’t feel like work, though, it’s more like solving a puzzle. Some people like crossword puzzles or jigsaw puzzles; I like solving dish washing puzzles!
