Almost. 10% are put into a "Dev List" which starts with some coaching on how they should improve. It then likely leads to a "Pivot" where the employee is given the option to take a 3 month pay severance, or go on a Performance Improvement Plan (PIP) (likely biased against the employee, as manager and manager's manager have already put a lot of work into getting here and have made up their mind). Failing the PIP, they are likely going to be terminated soon and only get 1 month severance. So, they start with 10% but they target about 6-8% actually getting terminated.
