Implementation of a Visual System to Manage and Improve Failure Analysis Work Flow

Abstract

Many articles and books have been written that discuss and study the techniques of lean thinking and methodologies. The applications of these methodologies have included such industries as manufacturing, health care, and information technology. Application to analytical laboratories has been rare or non-existent due to the inability to apply lean methodologies to a process with ‘unique’ analytical work flows as well as a lack of a direct connection to the manufacturing value stream. The following paper describes the work done in a semiconductor failure analysis laboratory to visualize work flow, design a forecasting model, and create a management system. The result of which has been sustained and improved quality, resource utilization, and delivery of actionable root cause failure analysis.
