Implementation of Lean Six Sigma Approaches in Construction Operations
Lean Six Sigma (LSS) methodology is often successfully used to optimize processes, reducing defects and wastes in manufacturing processes, when applied in construction, improving its quality while reducing cost. Even though LSS has been widely used in construction processes all over the industries, it is rarely used in Libyan construction industry. Libyan constructions experience with material shortages, late material delivery, and lack of experienced design and project management, unstable process, and ineffective communications, inadequate planning and scheduling which results in along cycle time of the process. The purpose of this paper is to implement lean six sigma techniques as a sophisticated tool in Libyan Construction projects. Value stream mapping (VSM) is considered as a special type of flow chart that uses to depict and improve the flow of process steps and information from origin to delivery to the customer.
