Count the work a new tool will create

Follow one ordinary week

A feature list describes what a tool can do. A work map describes what you will have to do because you own it. Start with the recurring interruption you want to remove, then follow one ordinary week: connecting the tool, using it, dealing with a failure and putting it away.

Write each new step beside the step it replaces. A device that removes one awkward connection but adds pairing, charging and a second configuration utility may still be useful. The point is to see the exchange before making it.

Separate the first afternoon from the routine

Make three lists: setup once, repeat during use, and recover when something goes wrong. Keep money, time and uncertainty separate. A known cable purchase is a cost; an unknown update routine is a question to investigate. Neither needs an invented productivity percentage.

• Setup: installation, accounts, cables and learning.
• Routine: charging, updates, subscriptions and repeated adjustments.
• Recovery: restoring settings, finding a replacement or using the old method.

Compare complete arrangements

For example, consider a hypothetical meeting accessory that needs its own account and a cable you do not own. Compare the accessory plus those dependencies with your current meeting checklist. Do not compare the new accessory alone with every inconvenience of the existing setup.

Ask which new responsibility you would accept to remove the original interruption. If the benefit depends on a feature you cannot verify, leave the decision open rather than counting that benefit as already delivered.

Write a condition for keeping it

Finish with one sentence: “I will keep this if it removes [specific interruption] without adding [unacceptable recurring task].” Review the arrangement after trying it under the seller’s actual terms. You are testing the fit of a setup, not proving that new hardware is automatically more productive.
