Initial Diagnosis
Summary of the issue
An alarm triggered at 3:21 PM on Nov. 2nd, indicating an anomaly in cookie shape on the production line where more than 11 deformed cookies were produced within a 5 minute period.

Potential root causes
Issues with cookie dough extruder: Worn parts could be causing uneven dough flow resulting in misshapen cookies.

Problems with conveyor belt: An uneven or slipping conveyor belt could cause cookies to deform before entering the oven.

Oven temperature fluctuations: Inconsistent oven temperatures across belts/zones may result in uneven baking and cookie deformation.

Dough ingredient inconsistencies: Variations in dough ingredient ratios/qualities could impact the shape-retaining properties of the dough.

Improper dough mixing: Inadequate or too vigorous mixing could develop structural flaws in the dough affecting cookie shape.

The line operators may want to inspect the extruder, conveyor belt and oven conditions/recordings to identify potential issues causing the deformed cookies. It may also help to check dough ingredients and mixing processes. Resolving mechanical or process problems should help reduce deformed cookie counts.
