The three key principles of Quality provide just that. It is not a question of what is better or more expensive. Quality is based upon meeting customer needs. This entails the supplier knowing and conforming to customer requirements. To have Quality, all customers inside and outside the organization must be satisfied.
Quality is customer satisfaction.
Close is not good enough. To achieve Quality, everyone at Your Company must have a defect free attitude in what they do. This includes products or services provided to others or received from others. PONQ is what it costs Your Company in time, money or opportunity when things are not being done the best way. The price of non quality is determined by placing a dollar figure on problems.
