Computer Science homework help. Note: When responding to the issues/questions for this week, please make sure that at least one of your posts is supported by a specific quotation from the assigned text readings. This means that you have to use the actual words of the author(s). Simply including the text as a reference at the end of your post is not sufficient. Failure to do so will result in receiving less than the eligible maximum amount of points for this discussion. We define employees performance levels as A, B, and C levels. A Performers are defined as superstars, B Performers as steady with potential to become A Players, and C Players as marginal (needing remediation). How does an effective performance management system contribute to true performance differentiation among different levels of performance?
