Measuring time saved
🎯You'll be able to
Measure time, errors and delay before and after an automation, and work out a simple payback estimate.
🏠The everyday picture
A family switches from cooking on a stove to a pressure cooker. They don't just say "it feels faster": they notice dal now takes 15 minutes instead of 45, and the gas cylinder lasts longer. Clear numbers make the change easy to judge.
📘What it really is
- To show an automation is worth it, measure before and after:
- time: minutes per task × how often it happens;
- errors: wrong phone numbers, missed orders, duplicate messages;
- delay: how long a customer waits for a response or update;
-
cost: platform fees, setup time, and the time to maintain it.
-
A simple payback estimate: hours to build and test ÷ hours saved per week = weeks until it pays for itself.
-
Include maintenance: apps change, passwords expire, and workflows need checking. A fair estimate adds an hour or two a month per workflow.
-
Report results honestly. A workflow that saves 30 minutes a week and removes mistakes is a good result, even if it isn't dramatic.
📝A worked example
Shipping messages at Sharma Textiles:
- Before: 55 messages a week × 2 minutes = 110 minutes. About 3 wrong numbers a week, each causing a customer call.
- Build and test: about 6 hours.
-
After: about 10 minutes a week checking the workflow's log; wrong numbers fall to near zero because the phone is copied, not retyped.
-
Saving: about 100 minutes a week, so the build pays back in roughly 4 weeks, plus fewer confused customers.
- Cost: the platform plan, and about 1 hour a month of upkeep.
🌍Where it's used
- Proposals: clients approve projects that show a clear payback.
- Internal reports: operations managers track hours saved across all workflows.
- Pricing your work: freelancers often price by value, using the time saved as evidence.
- Deciding what to switch off: workflows that save little and break often are candidates for removal.
📝Case scenario
A manager says an automation "didn't help" because staff still seem busy. You compare the task diary from before with the workflow's run log: 400 invoices were sent automatically last month, which used to take 20 hours. The staff are busy with new customer calls the team never had time for before. You present both numbers, and the manager sees where the time went.
🖱️Try it
For one of your chosen tasks, write a before-and-after estimate: weekly minutes now, build hours, expected minutes after, monthly upkeep and payback in weeks. Add one measure that isn't time, such as errors or customer waiting time.
⚠️Common mistakes
- Guessing the before figures. Sign: "it takes ages" instead of minutes. Fix: keep a task diary for a week before you build.
- Forgetting upkeep. Sign: the payback ignores maintenance. Fix: subtract a monthly upkeep estimate from hours saved before working out payback.
🛠️For your project
Your capstone case study reports before and after figures. Label figures from the practice simulator as test results on synthetic data, not as measured savings.
✅Quick check
How do you estimate payback for an automation?
Show the answer
Divide the hours it takes to build and test by the hours it saves each week, to get the number of weeks until it pays back.
Why include maintenance in the estimate?
Show the answer
Apps and logins change, so workflows need checking and fixing; ignoring that makes the saving look bigger than it is.
