Did you give the employee a copy of the self-assessment and your appraisal draft one week before the meeting?
Have you set an appointment at a convenient time for the employee? Have you allowed sufficient time for your interview? Have you made sure there will be no interruptions?
Did you brief the employee before the interview so the employee knows to come prepared to discuss past performance and future performance?
Has the employee been able to complete those sections for which he or she is responsible?
