DD replied to the topic check the link(1.5 shift) , is this true? in the forum General 17 years, 5 months ago

DD replied to the topic supply chain management Six Sigma in the forum General 18 years ago
To me, Six Sigma is a philosophy and a set of tools that can be used in a variety of functional areas to address waste.
