The role of lean six sigma in the optimization of a seaport process case study: port company DjenDje

Abstract

Lean Six Sigma methodology was first introduced in the manufacturing industry to be later adopted by other sectors, namely the service industry. The combination of the two methods Lean and Six Sigma aims at process optimization by acting on wastage and variability sources through DMAIC process. In such an activity where time is valuable, Lean Six Sigma methodology significantly contributes to the optimization of the trilogy (Cost-quality-time), but also by considering the notion of risk/opportunity resulting in a better mastery of processes. This paper combines Lean Six Sigma optimization concepts with port processes optimization opportunities. Key
