In this Lean Documents, Lean Configuration, and Document Control training learn the different types of lean documents and the usage of lean document principles; types of controlled documents; examples of lean and non-lean controlled documents. Pros and cons of lean vs. non-lean documents. Just as a manufacturing process produces a product, controlled documents are the product of a business process. Just as in manufacturing, a product cannot move forward if it is waiting for component parts, a document cannot move forward if it is waiting for information, or if its use is constrained by other documents. Although many life science companies advocate lean manufacturing, lean laboratory, and lean operations, they have cumbersome controlled documents and systems which cause significant operating expenses, and make it difficult to introduce process improvements in a timely manner.
