Lean manufacturing has been widely used to increase operational excellence and performance in manufacturing systems. Nevertheless, this approach presents several limits, such as the lack of alignment between lean objectives and strategic management of a company, and the lack of justified measurements for futures Lean implementations. Nowadays, it remains difficult to evaluate the leanness of a manufacturing system due to the lack of relevant indicators and methods to evaluate them. This paper presents framework to overcome these limits: the Lean & Six-Sigma Framework (LSSF). It allows a company to evaluate, justify and enable future lean implementation in line with strategic missions and objectives of the company. This framework is based on real time information exchange with several information systems such as the Manufacturing Execution System and the Enterprise Resources Planning.
