Finding the right project manager (PM) for your company (or a professional for any position you are attempting to fill, really) is often a mix between rocket science and taking a leap of faith.
Note: A positive correlation coefficient indicates a positive relationship between two variables, such that one variable goes up as the other one goes up as well, and vice versa. The closer the coefficient to 1 (positive) or -1 (negative), the stronger the association.
How others perceive the PM, for instance via referrals, is a strong measure of an individual’s success. Building a strong and supportive professional network has a significant impact on your current position and rate of advancement.
By looking at this data you can gain interesting insights into where the most successful PMs turn their attention.
