A sales manager is evaluating the team's performance by identifying which salesperson was the top performer and considering all other members of the sales team based on that salesperson's performance. Which approach is the sales manager using to evaluate performance?

The graphic rating scale is a tool used to assess an employee’s performance against a set of predefined criteria or traits, typically rated on a scale. It does not focus on comparing employees to one another; instead, it evaluates each individual based on their own performance standards. This method does not align with the manager's approach of evaluating based on the top salesperson.

A behavioral checklist consists of specific behaviors that are expected from employees, which are then checked off as observed. This method measures an employee’s performance based on their adherence to expected behaviors rather than comparing their performance against that of others. Thus, it does not fit the manager's comparative evaluation strategy.

Peer assessment involves colleagues evaluating each other's performance, typically focusing on collaborative work and contributions within a team. This method emphasizes individual perceptions from peers rather than a comparison to a top performer, which is not the approach the sales manager is taking.
