performance management systems

HR EXPERIENCE NEEDEd

Organizations often do a poor job of measuring the effectiveness of their performance management systems.

Review Chapter 7 of our textbook, and list and describe three of the indicators (i.e., measures) used to monitor and evaluate the effectiveness of a performance management system.
When or how often should such evaluations take place?
Of the measures you selected, which one would be the most important in understanding effectiveness?
Why is it difficult (or not difficult) for organizations to measure the effectiveness of their performance management system?
Please share any experience you have in this area.
