Abstract
Lean Six Sigma is a popular method of management that encourages teamwork in the workplace to boost productivity and quality. It combines Lean Manufacturing with the Six Sigma quality management system, two of the most important ideas for ongoing industrial advancement. When it comes to the goal of enhancing corporate procedures and systems, the Lean Six Sigma methodology takes a more international approach. Because of its all-encompassing nature, this method of doing business is applicable to a wide range of different arenas in addition to the commercial and manufacturing sectors.
The LSS approach was utilized in this study to examine the retail industry in South Africa. Waste reduction and better store operations were primary objectives. LSS is a method that equips businesses with the resources they need to optimize their internal processes. Back in the '90s, Motorola was hard at work on it. Improving profitability, staff morale, and product quality may all be facilitated by reducing process variation and maximizing performance. The LSS approach has, ever since its conception, been shown to be a very effective change agent and business process improvement catalyst in the industrial sector. The retail industry in South Africa was one of the first industries in the world to implement LSS.
This thesis provides a comprehensive account of one of the pioneering efforts implemented in South African retail industry to implement Lean Six Sigma, which paved a way for application on the entire LSS. The concept for this study was inspired by the lack of success that LSS applications to service-based businesses, particularly in the retail sector, encountered. LSS practices could offer South African businesses a competitive edge, allowing them to successfully compete in global markets. The primary goal of this research is to investigate the viability of applying Lean Six Sigma strategies and procedures to a service-oriented retail firm in South Africa in order to boost overall productivity and save operational expenses. It provides a sought answer to a primary research question; “To what extend does the implementation of LSS in the South African retail firm impact on it performance?”
The nature of this research may be described as both exploratory and descriptive. It generates crucial components involved a thorough research of the relevant literature, administors of questionnaires and surveys, and provides in-depth discussions with
industry experts.
There was a lack of clarity between the processes of a Generic Statistical Business Process Model (GSBPM) for collecting and analysing data, and this thesis explains the four-year process of adopting a Define-Measure-Analyze-Improve-Control (DMAIC) framework to a business survey that employed the process technique. The process was described as having a process method and where there was a lack of clarity between the steps of GSBPM for collecting and analysing data. It details the steps that were taken to enhance the statistical processing, as well as the safeguards that were taken to guarantee that the newly implemented technique would not go back to its previous levels of efficiency. The real advantages that were obtained as a result of implementing the adjustments are also discussed in further detail
