What does the hotel u, p, sp and k mean?

This is a performance evaluation system. First of all, we must set a goal, and the goal must be set according to the SMART principle. Take the sales target as an example. Suppose I have 65,438+000 sets of products to sell, my manager and I should expect four results, such as sales of less than 60 sets are rated as U, poor performance (not up to standard), sales of 60-79 sets are rated as P, and average performance (average performance). Those with sales of 80-89 units are rated as SP, strong performers, and those with sales of more than 90- 100 units are rated as K, key contributors.
