Definition of a “Bakery Troubleshooter”
• In a bakery environment, a “trouble shooter” is a skilled baker who is able to determine the cause of why a product fails to meet the expected quality standards. Not only is the baker able to determine the contributing factors, but she or he is able to make the necessary formulation and/or processing adjustments to get the product quality back to where it should be.

The Four Buckets• People
– Are your people well trained?– Do they have the tools and
staff they need?• Ingredients
– Are the ingredients correct, fresh, and known to the staff?
• Process– Are correct procedures being followed by staff?– Is the machinery running correctly?
• Product– What is causing product faults?
