The fifth principle of Lean manufacturing - Seek Perfection - addresses behavioral expectations. Seeking perfection is often one of the most difficult principles to successfully apply in the workplace. This requires high-quality people working together to produce and deliver competitive quality product while achieving and sustaining its desired profitability through a culture of continuous improvement. Without addressing work behavior in the workplace, aligning standards with organizational core objectives will not be enough to realize the ultimate goal of a Lean organization where everyone continuously improves processes, identifies waste and flows the product.
Positive reinforcement is the most powerful tool to create desired behavioral expectations in the workplace and crucial for anyone in a leadership role to understand and use.
