[Core] What metrics do you pay attention to in a buyer / procurement role, and why?

Example Answer

The exact metrics depend on the role, but I usually care about a mix of execution and commercial signals: on-time delivery, lead-time performance, expedite volume, supplier quality issues, price movement, savings credibility, PO accuracy, and how often internal demand is showing up late or unstable.

I do not want metrics just to look busy. I want them to tell me where the process is drifting, where supplier risk is rising, and whether procurement is helping the business make better decisions or just reacting after the fact. The most useful metrics are the ones that change behavior, not just reporting.

For example, I would define an on-time measure at a consistent grain, such as order lines due in the month that were received in full by the original agreed date, divided by all lines due in that month. Ten due lines with eight on time, one late and one still undelivered give 80%, not eight out of the nine already received. I would document treatment of approved changes and cancellations and retain the original promise. I would investigate causes before attributing every miss to the supplier; quality, realized cost and overdue open lines remain separate signals.

Common Poor Answer to Avoid

"I look at whatever KPIs the company tracks and try to keep them green."

Why it's weak

It accepts headline indicators without defining their grain, denominator or connection to useful decisions.

Why this works

It addresses procurement measurement with a practical explanation and without inventing career results.
