Engineering is a continual lesson in axe-sharpening (if you have 6 hours to chop down a tree, spend the first 4 sharpening your axe).

My favorite framing, from Kent Beck: “first make the change easy, then make the easy change.”

I recently got assigned to enhance some code I've never seen before. The code was so bad that I'd have to fully understand it and change multiple places to make my enhancement. I decided that if I was going to be doing that anyway, I might as well refactor it into a better state first. It feels so good to make things better instead of just making them do an extra thing.

Just be careful that 'better' doesn't just mean 'written by me'. I've seen that a lot too

I don't think you spend all 4 hours up front, friend.

In my experience you're going to want a sharp axe later in the process, once you've dulled it.

Not sure if that ruins the analogy or not.

This approach is also what I'm still missing in agentic coding. It's even worse there because the AI can churn out code and never think "I've typed the same thing 5x now. This can't be right.".

So they never make the change easy because every change is easy to them... until the lack of structure and re-use makes any further changes almost impossible.

I have mixed feelings here because on one hand I prefer the “axe” when programming (vim with only the right extensions and options). But for trees… chainsaws are quite a bit easier. Once it is chopped down, maybe rent a wood splitter.

You semi-regular reminder that Kent Beck was one of the XP brain trust behind the Chrysler Comprehensive Compensation System disaster.

Most of my colleagues are content to spend 50 hours chopping up the tree with a pipe. We don't have time to spend making things work properly! This tree has to be finished by tomorrow! Maybe after we've cut up this forest, then we'll have a bit of spare time to sharpen things.

As Charlie Munger used to say “show me the incentives and I’ll show you the outcome”.

What are the incentives for these developers? Most businesses want trees on trucks. That’s the only box they care to check. There is no box for doing it with a sharp axe. You might care, and take the time to sharpen all the axes. Everyone will love it, you might get a pat on the back and a round of applause, but you didn’t check any boxes for the business. Everyone will proceed to go through all the axes until they are dull, and keeping chopping anyway.

I see 2 year old projects that are considered legacy systems. They have an insurmountable amount of technical debt. No one can touch anything without breaking half a dozen others. Everyone who worked on it gets reasonable rewarded for shipping a product, and they just move on. The business got its initial boxes checked and everyone who was looking for a promotion got it. What other incentives are there?

It's not about incentives; it's just bad management. As you said, the business just wants trees on trucks, so good management would realise that you need to spend some time sharpening axes to get trees on trucks quickly. It just seems to be something that a lot of software managers don't get.

I don't think every company is like this though. E.g. Google and Amazon obviously have spent a mountain of time sharpening their own axes. Amazon even made an axe so sharp they could sell it to half the world.

Early on in Amazon’s history (long before same day shipping), they added a feature that would tell you, on a product page, whether you had recently bought that same product. The metrics spoke loud and clear: it caused purchase count to go down. Human common sense about the customer’s experience overruled the data and they have some variation of that feature to this day. That’s the “customer obsession,” but unfortunately most businesses only copy the “data driven”.

There is some amount of time to spend on sharpening that, if you spend either more or less time sharpening, net amount of trees on trucks goes down. Smart businesses look for that amount. Really smart businesses know what the amount is, and make sure that they spend very close to that amount of time sharpening.
