Verification Cost and Net Value
Why this matters
Every AI use has a cost that is usually ignored: the cost of checking the output. A system that saves ten minutes and costs twelve minutes of verification is not a win — it is a tax. Net value is simple: Benefit − (setup + review + correction + tool + switching cost). Run the numbers, not the hopes.
What you will be able to decide after this
- Whether a task is genuinely worth AI assistance before you spend the setup time.
- What "verification cost" actually includes in a real task of yours.
- When the honest answer to "should I use AI for this?" is no.
Core lesson
The equation:
Net value = benefit − (setup + review + correction + tool + switching cost)
Every term matters, but review is the one everyone forgets. Review is the time you spend confirming the output is correct: checking numbers, reading sources, tracing claims, fixing errors.
Two rules of thumb:
- Low verification cost tasks — where you already know what good looks like and can check quickly — are good candidates.
- High verification cost tasks — where you have to research or re-do the work to know if the output is right — are usually net negative.
An unpleasant task is not automatically a good AI task. The dislike you feel for a task does not show up in the equation. The checking time does.
Worked example
A financial analyst wants AI to draft variance commentary for the monthly report. Generation takes four minutes. Checking takes thirty — reconciling every number against the actuals, because a wrong number in variance commentary is not a typo, it is a liability. Net value: negative. The analyst was not being inefficient; they were being right, slowly.
The same analyst's weekly status blurb, drafted from approved notes, checks in ninety seconds because they already know what the notes say. That one is a win.
Practice
Pick one task you currently do. Estimate — do not measure yet — the setup, review, and correction cost you would actually pay. Guess. Then run the real measurement in the Apply step and compare.
Apply — produce the artifact
Pick one recurring task. Do it the current way. Time it. Note errors and rework. Do it with AI. Time the whole process including verification. Calculate the actual net value using real numbers, not hopes.
Verify
Show the before/after numbers and the verification steps you took to someone else. If the verification time was not measured, the exercise is incomplete.
