The Effect of Lean Techniques on Elimination of Waste in Composite Panel Production Using Paired t-test

Abstract

'A penny saved is a penny earned' as this phrase says it all, the key for increased profit lies in the elimination of non-value adding actions in any production process. This study concentrates mainly on the procedures to identify and to reduce the different types of wastes in a production process. Initially the data related to types of waste and their classification according lean techniques were analyzed and implemented on a production process. The data were recorded for a whole month before implementation and for a whole month after implementation. Later the influence of the lean techniques was analyzed on two different sections of waste, for 5% significance value using paired t-test. It was found that there is a positive impact of lean techniques on some areas of production flow.
