The only effect personnel action in the last 20 years was the 1,000 manager reductions.
Intel is full of terrible managers who don't know how grow employees. Many of these managers don't want to be managers, they were world class engineers who became terrible, incompetent managers. These bad managers will not promote any employee past a certain grade level. This is bad for that manager's employees (who never get the opportunity to advance), for Intel (who doesn't get expected growth from the employees, or from the manager who doesn't grow because he's not growing his own employees)
These bad managers survive because the employees they manage who reach the maximum level eventually leave, and they are replaced by RCG's. So the manager is constantly training new RCG's so he gets credit for "career development", even though no development actually occurred. Just a task was transferred to a different name.
There are managers who have been doing this for 20 years, never growing any employee behind a certain level, and never grow their own management skills, most importantly they do not improve the overall output of the entire team.
Most of the employees who were ISP'd, VSP'd were managed by bad managers as I describe, they just reached the maximum level their manager was able to deal with, and their manager failed to give them an opportunity to advance.
So Intel should identify these bad managers and eliminate them, they are completely useless and are holding back good employees as well as the entire corporation. The criteria should be very simple and done with simple SQL query. Like any manager who hasn't promoted an employee by 1 grade level for every 3 years he's been a manager. So for example a manager who has been manager for 15 years should have promoted an employee to at least 5 grade levels higher than where they hired into the company. If not, there's an issue with how effective that manager is actually developing careers.
