Straight answer here.
Did you deserve your PIP? If so, you won't pass it.
If you didn't deserve your PIP, your chances are directly proportional to how much support you will get from your direct and program management.
I was NSI last year for "not having enough influence over the organization as a whole at my CL" and one of the options was PIP.
I took the PIP, but I also had the support of my management. They knew the NSI was bu-----t. The only thing I did differently during the PIP was document every interaction I had outside of Agile assigned tasks and "fit" the interactions into a review with my SDM every 2 weeks.
I passed the PIP. Then took the retirement package last year. I'm still working, doing practically the same job for Microsoft. And glad I left as well.
