Break the work into discover, build, test, and document steps. Give each step a realistic range, remembering that the last ten percent takes longer. Add buffer for edge cases and data quirks you will uncover only during trial runs. Logging time as you go keeps estimates grounded. That discipline protects your schedule, avoids midnight surprises, and helps future you reuse the same estimates when proposing similar micro automations.
APIs change, file paths move, and teammates rename columns without warning. Assume occasional breakage and budget time to fix it. Write quick notes explaining inputs, outputs, and expected formats so anyone can repair it under pressure. Schedule a tiny quarterly checkup to run tests, update tokens, and refresh documentation. Treat maintenance as part of the investment, and your ROI math becomes realistic instead of brittle optimism that disappears at the first unexpected update.
Even small tools involve setup, authentication, permissions, and a little practice. Capture the minutes spent learning shortcuts, reading a quick tutorial, or watching a three‑minute video. If you switch editors, browsers, or data sources, include that overhead too. These minutes count against payback, yet they are often one‑time costs. Making them visible strengthens your argument and helps others adopt the same automation with clear expectations and fewer onboarding surprises.
