When there's no metric to give
Most advice about proving impact assumes a number was sitting there the whole time, waiting to be written down. In plenty of jobs it wasn't. Inventing one is worse than leaving the line as it is.
“Quantify your impact” works cleanly for a job with a target already attached to it: revenue, tickets closed, days saved. It works badly for a job where the value was in something not measured in the first place. A difficult situation handled calmly, a person who was struggling and wasn't any more, a process that used to break and now doesn't.
The honest options are not “find a number” or “say nothing useful.” There is a third: evidence specific enough to be checked without being a number.
A number exists
Something was already counted before you needed a CV line: a total, a percentage, a time saved, a headcount managed.
Use it as it actually was. Not rounded up, not the best month presented as the average one. A specific, checkable figure survives a follow-up question, and an inflated one doesn't.
Nothing was counted
The value was real but nobody was tracking a metric for it. Most support, care, and early-career operational work lives here.
What still counts: frequency (“the thing that used to happen weekly stopped happening”). Scale in words (“across the whole team,” not one person). And who noticed. A manager, a customer, a complaint that stopped arriving.
Friday asks the question that finds the frequency, the scale, or the outcome, rather than asking you for a number that was never there.
Check your CVA number you made up survives until someone asks where it came from. A specific true thing survives the question.
“Quantify your impact” is asking for something checkable, and a number is the easiest way to be checkable rather than the only one. Someone who took over an escalation queue has the makings of a line without a metric in it: how far behind the queue ran before, what it ran at afterwards, and how long they held it there. To anyone who has run a queue, that carries what a percentage would.
What doesn't work is skipping the line because there's no number for it, or reaching for one that isn't real. Both read as absence to the person deciding whether to interview you. One of them is honest about it.
Which of these an employer wanted is usually in the advert, in a phrase rather than a requirement: what ‘fast-paced’ and ‘wear many hats’ are asking for.
Upload your CV and an advert, and Friday tells you what's evidenced, what's thin, and what's missing. It never invents a number to fill the gap.
Friday is a career evidence engine for people who have done the work and cannot get the page to show it.
It is early and there are rough edges. What people report is what gets fixed first.
Paste as many adverts as you like, and one CV is composed for you to keep. The record stays yours whether or not you ever pay.
