At a Big Corp where I worked, I think it was three 'satisfactory' ratings in a row which resulted in a PIP.

Satisfactory: fulfilling expectations or needs. But not in Corporate Nu-Speak.

I recall British telecom it was "needs some improvement" that triggered a pip that but everyone has some thing that needs improvement.

Given the will you can find an excuse to put anyone on a PIP.
