This thesis is preformed at Electrolux Plastics division in Adelaide, South Australia. The purpose is to increase the efficiency in the Plastic moulding operation, which has been struggling with low direct labour efficiency since the introduction of two new product families. The target is to improve the efficiency from 56% to 75% with a stretched goal of 85%. By using methods of mapping the organisation and dividing the production into Value adding and Non Value adding work, lacks in the efficiency has been found and suggestions on how to solve these problems made. Interviews, observations, theoretical studies, benchmarking visits and participation in production have been some of the used in order to make a reliable study. To improve the efficiency even more and to take the study one step further a sharp project “The machine #40 project” has been conducted as a step towards improving the efficiency at a certain machine by reducing the number of operators required in the operation. The study has resulted in three subsequent projects at Electrolux Plastics division and together with “The machine #40 project” the efficiency level reaches 69%, as a result of this thesis.
