What Is The Definition of "The Performance Review Meeting"

In Performance Management - A Briefcase Book (McGraw-Hill) Robert Bacal defines the performance review meeting as follows:

The performance review meeting is a process where manager and employee work together to assess the degree to which the employee ha attained agree-upon goals, and work together to ocercome any difficulties encountered. Aslo called performance appraisal meeting, or performance evaluation meeting. Usually refers to an annual meeting.

However, there's considerable merit in holding shorter performance review meetings throughout the year, since doing so can prevent small performance problems from becoming larger ones. Also, the longer performance issues exist, the harder they are to remedy, so it makes sense to have meeting more often than just annually.
