Time Spent on Automation vs. Time Saved
An honest calculation of whether the hours poured into automation were actually worth it.
A Notion Doc Would've Done the Job, but I Built a Slack Bot
The team had frequently asked questions. "What's the staging server URL?", "Where's the Swagger docs for this API?", "Is there a deployment scheduled today?" Answering these ate about 10 minutes a day.
I built a Slack bot. A simple bot that auto-responds to certain keywords with links. Development took 8 hours.
Honestly, this was overengineering. A single Notion doc with a list of links would've taken 1 hour. I lost to the developer instinct of solving everything with code.
Even though I know that famous XKCD comic.
But Deployment Automation Was Absolutely Worth It
Every deployment meant SSH in, git pull, npm install, build, pm2 restart. Each run took about 8 minutes. Deploying twice a day on average meant 16 minutes daily.
Automating with GitHub Actions took 6 hours. Push triggers build and deploy automatically.
Time invested: 360 minutes. Daily time saved: 16 minutes. Break-even in 23 days. Over a year, roughly 65 hours saved. This was clearly a winning trade.
Test Data Generation Was a Good One Too
The QA team kept requesting test data. Logging into the admin panel to manually create 10 products, 20 orders, and 5 users took 30 minutes. Requests came 2-3 times a week.
Building a test data generation script with Faker.js took 4 hours. npm run seed sets up the test environment in 30 seconds.
Time invested: 240 minutes. Weekly time saved: 60-90 minutes. Break-even in 3-4 weeks. And once the QA team could run it themselves, the communication overhead dropped too.
(The QA team was genuinely grateful for this one.)
The Real Trap of Automation
Like the third example shows, automation can sometimes blind you to simpler solutions. Developers have an instinct to solve problems with code. But a single document or checklist is often more effective than 500 lines of code.
The question shouldn't be "can I automate this?" but "should I automate this?"
How I Decide What's Worth Automating
By my criteria, a task is worth automating when it meets three conditions: high repetition frequency (3+ times per week), risk of human error in manual execution, and implementation takes no more than a day.
Deployments, test environment setup, linting and formatting, CI/CD -- these have clear ROI.
On the other hand, monthly report generation or quarterly reconciliation? Manual is fine.
It's Okay to Just Do the 10-Minute Task by Hand
When you're deep in automation mode, you can miss what really matters. The time spent building automation scripts could have gone to shipping a feature. The time maintaining those scripts could have reduced tech debt.
It comes down to balance. Automation is a means, not an end. Calculate the ROI honestly, and invest only where it genuinely makes sense.
