PPIC Demand & Production Validation Analysis

Objective

Evaluate the effectiveness of PPIC planning by comparing planned production with actual demand and output

Project Details

• Analyzed planning buffer vs actual demand and measured deviations between plans and sales orders (SO).
• Identified overproduction and underproduction patterns, finding that existing buffer logic significantly deviated from actual demand.
• Rebuilt buffer logic based on historical demand patterns, reducing forecast deviation by >95%.
• Improved data structure to reduce manual inputs and align with data principles.
• Found that demand shows consistent recurring patterns over time which were not reflected in the old planning method.
• Demonstrated that the revised buffer approach significantly improves alignment with actual demand and planning accuracy.
