The embodiments described herein relate to methods, systems, and computer program products for improving the product quality of product lots produced on a production line. A quality value for each product lot is determined, and a quality benchmark is established. Each product lot is classified based on the quality benchmark. Product lots that have a quality value meeting the quality benchmark are classified as quality lots, and product lots having a quality value failing to meet the quality benchmark are classified as failing lots. Tools used in the production of the product lots are identified, which includes identifying a set of quality tools and a set of failing tools. Routing of additional product lots is directed by shifting production at least substantially to the set of quality tools.

Production line quality processes

Methods, systems, and software for improving the product quality of a production line having multiple production steps, at least some of which employ multiple individual tools, including producing product lots using different combinations of tools, setting a quality benchmark for the resulting product lots, identifying product lots that meet the quality benchmark, identifying the tools used to produce the identified quality product lots, and producing additional product lots using at least substantially the identified quality tools.
