Breaking Free from Busy Work: Applying the 80/20 Rule in Engineering
Busy Work vs Real Impact in Engineering
Most weeks, the work that drains the most energy is not the hard stuff. It’s the busy stuff.
The tickets that feel satisfying to close.
The refactors that make the code just a little cleaner.
The tiny UI tweaks that only a handful of people will ever notice.
All of that feels like progress.
The problem is that a lot of it barely moves the product or the team forward.
The Pareto principle (the 80/20 rule) says that a small share of effort typically produces a large share of results: roughly 20% of your work drives 80% of your outcomes. If that’s true, it also means something uncomfortable: a big chunk of your time is probably going into things that look like work, but don’t really change much.
How busy work shows up for engineers
In engineering, busy work often arrives disguised as “real work”:
Tweaking spacing, colors, or animations long before users confirm they even want the feature.
Refactoring code that’s annoying but not blocking any roadmap item or customer.
Building internal tools that are fun to write but remove small inconveniences instead of major pain.
On a board, these look legitimate. They’re real tasks, with estimates and assignees.
The cost isn’t that they’re totally useless. The cost is that they push more impactful work to “later”.
Busy work as a starter task
Busy work isn’t always the enemy. Sometimes it’s a useful on‑ramp. There are days when starting with a small, easy win is exactly what’s needed:
fix a tiny bug,
clean up a file,
rename something that’s been bothering you.
You get a quick success, your brain switches into “doing mode”, and suddenly the bigger, scarier task feels less heavy.
The problem isn’t doing a bit of busy work.
The problem is staying there—spending most of the week in low‑impact tasks and never coming back to the 20% of work that actually drives outcomes.
Using 80/20 to avoid busy work
The 80/20 rule is useful not just as a description, but as a filter.
If roughly 20% of your effort creates 80% of the impact, then your job is to find and protect that 20% as aggressively as possible. In practice, that means asking:
Which few features, decisions, or fixes would actually change a user’s week?
Which conversations or decisions would unblock the most work for the team?
A simple mental graph you can imagine:
On the X‑axis: time spent.
On the Y‑axis: impact.
The first fifth of the graph shoots up quickly (20% of time → 80% of impact).
The remaining four‑fifths flatten out into a long tail—lots of effort, small gains.
The goal is to spend more of your week in that steep early part of the curve, and less in the long, flat tail where busy work lives.
The 80/20 version of tech debt
Technical debt is the same story with different branding.
Taking on debt on purpose can be the right call. You ship a rough version, learn from real users, and then decide what’s worth cleaning up. But there’s also a version of tech debt where you spend weeks polishing things that don’t justify the investment.
Viewed through the 80/20 lens:
The first 20% of effort gives you 80% of the value: a working feature in production, feedback from users, a clearer sense of what matters.
The last 80% of effort goes into chasing perfect abstractions, solving edge cases no one has hit yet, and rewriting code that already works “well enough”.
Here, 80/20 helps with decisions:
If a piece of debt is blocking that high‑impact 20% of work, pay it down early.
If it only affects the long tail of polish, log it, time‑box it, and tackle it later—if it’s still worth it.
Sometimes that last 20% is truly important (compliance, safety, scalability).
Often it’s just comfortable busy work wearing a “quality” badge.
Why busy work is so attractive
There’s a reason this pattern is hard to break - busy work is emotionally easier:
It’s clear - you know exactly what to do and how to finish it.
It’s controllable - no stakeholder disagreement, no product ambiguity.
It’s rewarding - you get quick dopamine hits from closing tickets and merging PRs.
High‑impact work is messier. You need to align people, make trade‑offs, and say “no” to things. You need to pick a direction without all the data. It feels riskier, so your brain quietly drags you back to the safe zone - another refactor, another small UI tweak, another “just in case” improvement.
A simple heuristic: impact × reversibility
A practical way to avoid getting stuck in busy work is to quickly score tasks on two axes:
Impact – If this goes well, who notices? Users, teams, the business, or just me?
Reversibility – How hard is it to change or undo later if we get it wrong?
Then roughly prioritise:
High impact, low reversibility → design carefully, involve others, but still aim to ship.
High impact, high reversibility → ship fast, learn, and adjust as you go.
Low impact, anything → busy‑work candidates; handle them later, time‑box them, or drop them entirely.
This doesn’t need to be a formal matrix. Even asking these questions in your head already filters out a lot of “because it annoys me” tasks.
How this shows up in my own work
In practice, this is what it looks like for me when working on the GroundCTRL app (and not only):
With a new feature, I often spend too much time on the final 10–20% of tasks, like deciding on the exact appearance of a button or the arrangement of multiple buttons. The core 80% of the work—the part that actually changes something for the user—is already done, but I get stuck perfecting minor details.
For example, I spent about four hours creating a solid first version of the app with the help of AI. On other days, I’ve lost almost the same amount of time debating button aesthetics and layout, which doesn’t really move the product forward.
As a manager, I can also sink hours into “perfect” documentation, trying to cover every possible scenario. A more impactful move is often a short recording or a simple checklist that unblocks the team quickly.
The pattern is the same - I drift into high‑effort, low‑impact work because it feels safer than making the next significant decision.
Tactics to stay out of busy‑work mode
A few things that help push back against this:
Start the day/week a clear plan for 2–3 outcomes, not a giant task list. “Ship X”, “Unblock Y”, “Decide Z” beats 20 micro‑tasks.
Use busy work intentionally - one small task to warm up, then switch to a high‑impact item as soon as you have momentum.
Time‑box polish - only a small percentage of the feature’s total time is allowed for refactors and tweaks; after that, it ships as‑is.
Track intentional tech debt in one place and review it regularly, instead of trying to fix everything in the moment.
Ask once a day “If I stopped working now, what changed for someone outside the team?”. If the answer is “not much,” you’re probably in busy‑work territory.
The goal isn’t to ban busy work. It has its place as a warm‑up and as a finishing layer.
The goal is to keep most of your time in the 20% of work that actually bends the curve—and to use 80/20 as a simple lens for both avoiding busy work and deciding which tech debt really deserves your attention.
