The performance review stopped being an HR ritual and became a legal document.

Stack ranking is back. Layoffs run as scheduled programs. The software wants to write your reviews for you. And the words you put in a review this year become the explanation your employer hands to a pay-equity regulator, and to the attorneys reading discovery, next year. Most managers walk into review season unarmed for any of it.

The Performance Machine is the field manual for the system as it runs right now. Adam Mattis spent more than twenty years inside these systems, as the consultant hired to fix them and the executive accountable when they broke, and he wrote the book he kept wishing the people on both sides of the review table had.

It is built to be used out of order, in four parts:

The Machine. How the review system got its current shape, who re-armed it after the reform decade, and why its paperwork now answers to regulators.

Running the Machine. Setting expectations before evaluation, giving feedback the week it is earned, ranking and rating without lying to anyone, writing the review, and running the money conversation now that pay is public.

Surviving the Machine. What to do when a review goes badly, how to keep your own record, and how to grow on terms the system does not set for you.

Rebuilding the Machine. A blueprint for the people who have authority over how performance management works, and who can fix what is broken.

This is the descendant of Surviving Performance Reviews (2017), updated once in 2020 on the belief that the annual review was dying and something kinder was replacing it. That call was wrong. The machine was not dismantled. It was rebuilt with teeth, and this book treats it that way.

Whether you write reviews, receive them, or own the system that produces them, one line runs through all nineteen chapters: the most critical element of business success is people, and evaluation is where that truth is most easily destroyed.

Don't walk into review season unarmed.
