Addressing Employee Issues Through Change Management

Assume you are tasked with providing written and verbal quarterly performance reviews for each of your employees. You have one particular review to do for an employee, Bob, whom you have a great working relationship with. One of Bob's primary responsibilities is to ensure that each outgoing shipment is complete, all items are free of defects, and there are no discrepancies in inventory. In the past few months, however, several customers have complained about the shipments. In two cases, nearly every item in a shipment contained defects. Another concerning factor is inventory has several major discrepancies. Upon further investigation, the orders in question fall under Bob's purview. Bob's overall quarterly performance is poor, and you need to address the problems.
Assume the role of the plant manager. The corporate office has tasked you with addressing solutions for these issues with Bob. For your initial discussion post, identify one of Bob's errors and propose a change that he must implement to avoid similar issues in the future. Provide a description of how you would support the employee through proposed changes using the principles of change management.
