If you were to perform a review today, on any of your employees, would there be any surprises for them?
Have you set a goal for yourself to informally, but regularly, touch base with each of your employees to ask how things are going, ask whether there are any problems, and discuss any difficulties in the achievement of their performance?
Do you correct performance problems immediately?
Do you congratulate successes immediately? (And remember that success is relative: getting a supply requisition in on time can be a major success for a chronic procrastinator!)
Have you reviewed the employee's work plans and objectives at least once during the period?
Have you updated or modified those work plans and objectives that require revision? Have you done so with the employee's input and agreement?
