Abstract
The purpose of this paper is to analyze the problems encountered during the implementation and maintenance of Lean Six Sigma (LSS) at a marking and bolts manufacturing company in Namibia, herein referred to as BMS Namibia. The study is a single case study that was carried out at the factory of BMS Namibia in Windhoek. The factory manufactures a wide range of bolts, pin, cotters, and machine parts for export purposes. The study was conducted at the time when the company management wanted to optimize processes in order to improve productivity. Data was collected through a questionnaire with open ended questions. Participants were purposively selected from the operations and planning units of the company. A thematic approach was used to analyze data. It was established that the company’s processes were sufficiently equipped to enable the implementation of LSS. However, the company does not have continuous improvement program to keep the employees and management informed of the efficiency of their production system. Since LSS is one of the best productivity improvement methodologies embraced around the world, BMS Namibia needs to invest in the implementation of LSS and in providing relevant training to the employees and management.
