A new client asks you to recommend a performance appraisal method that would allow them to measure the amount of time that an employee was engaged in particular behaviors. What type of scale would you recommend?

Behavior-based appraisal

Explanation:

In Behavior-based appraisals, the employee is assessed based on what they do instead of what they produce. Their actions are assessed using a rating scale to measure specific behaviors. Behavior-based appraisals uses behavioral observation scales as opposed to practices that focus on results only. It tends to be more objective, fair and accurate, if the appraisal standards are carefully developed.

Behavior appraisals are very useful when assessing performance on quantitative tasks.
