Central to the sustainable and competitive growth of the South African construction industry is a predictable cash flow through on time payment by clients to contractors. However, chronic late payments, a recurring problem in the industry, especially in the public sector, is bringing untold hardship to contractors by derailing their competitiveness and also eroding the trust among the supply chain partners to the extent that some firms end up closing business in the industry. The situation is viewed from the lean construction perspective as an obstacle that is preventing the accrual of the required value to project parties in the construction industry. This research addresses the causes of late payments to contractors and the role of the quantity surveyor (QS) in terms of influencing early payment from a lean construction perspective. A mixed method approach was used for compiling the primary data for the study. Sequentially, one hundred and two (102) quantitative and twelve (12) interview questionnaires were administered to selected contractors and construction professionals working predominantly on public sector projects. The findings revealed that the approval process for evaluation and certification by the client- appointed agent and intermediary institutions is taking longer than contractually allowed, with parties independently undertaking their evaluation prior to the certification date. This is found to be adverse to achieving consensus on the values of the works for authorisation. Other significant barriers are the lack of funds to authorise payment, random auditor general’s documentation changes, lack of administrators’ system integration and capacity to handle cyclical payment processing. Also, contractors have been found to be in default of timeously submitting complete claim documents. It is therefore recommended that the client agents should partner with the contractor in regular design and documentation reviews, arranging the payment process and should also meet jointly to prepare monthly evaluations. In addition, contractors should be mentored from the onset of the project regarding all the necessary documentation and supporting documents that will be required by the client to ensure that payment approvals are not delayed. The payment authori-sation agent’s capacity should be enhanced through training and improved powers as a singular point of control to perform efficiently and their systems and processes should be integrated to ensure that all parties are implementing the same protocols.

South African SMMEs, just like their counterparts world-wide, play a very crucial role against the world economies. The competiveness of these SMMEs is therefore very important. Lean Manufacturing and its principles have been successfully applied by motor manufacturing industries over the years. Many other organisations has since followed suite and adopted lean manufacturing as an approach to optimise and better manage their resources while providing value to their customers. The objective of this study is to investigate how lean manufacturing techniques can be adopted by a specific SMME in a business of manufacturing security products for the banks to better manage its material flow and improve its competitiveness. The research uses observation method to gather information to develop the current value stream map and identify the wasteful procedures. The also involves the interviewing of staff members that are involved in the material handling within the organisation. The results from the two processes are explained and the future value stream map incorporating the lean techniques is developed and presented to the organisation.

This research report examines the changing nature of the organisation of work, in particular, the production methods in the South African automotive industry. The competition in the local and global markets has increased significantly in recent years. The increased complexity of products and individuality of customers pose strong challenges for the automotive manufacturers, (OEM – Original Equipment Manufacturers), with regard to product Quality, Cost and Delivery. For these challenges, Volkswagen Group South Africa, has defined objectives that, when met, will contribute towards establishing it as a leading automotive brand. It is aligned to the Volkswagen Group AG, Strategy Mach18, increased vehicle production and the creation of long-term delighted customer base. To achieve these objectives, the Volkswagen Production System (VPS) is an imperative component of the Volkswagen Group South Africa (VWGSA) production strategy. The core elements consist of, “Cycle”, “Flow”, “Pull” and “Perfection”. These are the four fundamentals on which Lean Manufacturing is built, as first introduced and described by the Toyota Production System. Lean manufacturing is a whole-systems approach that creates a culture in which everyone in the organisation continuously improves the process and production. Volkswagen Group South Africa is facing increased competition in the South African and global marketplace. A search of the internet revealed that extensive research has been conducted into Lean manufacturing in South Africa. However, no research is noted with regard to the sustainability of Lean manufacturing at Volkswagen Group South Africa. The aim of this study is to analyse the sustainability of the lean manufacturing implementation at VWGSA.

The interest on lean production is mostly based on the empirical evidence that it improves the company’s competitiveness. However, the implementation of lean manufacturing harbours enormous difficulties due to a broad-spectrum of variables, compounded by lack of standardised mechanisms within organisations of analysis and measure of value-adding capabilities. The purpose of this study was to understand from both a management and employees’ perspective, the relative importance of key success factors, specifically training, for successful implementation of the lean principles and to understand the impact of training on employees perceptions of the lean programme. A quantitative research methodology was conducted in a packaging manufacturing company and data, collected using a questionnaire from a sample size of 54 employees, was analysed using SPSS software. Employees were found to have developed good perceptions about the impact that training had in their own jobs and also perceived that the lean program overall added value in their organisation. Employees considered training and management commitment as the most critical factors for a successful lean implementation. For lean implementation to be successful employees must be given training that is relevant to their work and senior management of the organisation must show (display) commitment towards the lean program being implemented by making necessary resources (time, funds ) available for lean activities. / Thesis (MBA)-University of KwaZulu-Natal, Durban, 2012.

Dissertation (MTech( Mechanical Engineering)--Cape Peninsula University of Technology, 2011 / Lean thinking and its principles, as described by Womack and Jones (1996) has been successfully applied to the manufacturing and operational environment, as evidenced by associated case studies. Fostered by a rapid spread into many other sectors beyond the automotive industry, there has been a significant development and localisation of the lean concept in general. This research study sets out to investigate the effects of lean thinking on production processes in a Small and Medium Engineering Enterprise (SMEE). It is hoped that the methodology adopted and the results of the study in the form of a concise lean principle model will assist SMEEs in the strategic planning of their manufacturing processes and improve their sustainability. The case described here, where lean principles were adopted at a transformer manufacturing company (referred to as ABZ), was considered a success by most of those involved at the company. The production cycle time improved from 33 days to 4.5 days within a few weeks of the implementation. In addition; product quality, worker morale, and housekeeping also improved drastically.

The Republic of South Africa’s energy economy is under immense pressure and the main energy utility, Eskom, cannot reliably generate sufficient electrical energy to meet its customer demand. Water security in South Africa is also under threat as the country is currently amidst a water crisis. The South African manufacturing industry is the sector consuming the largest portion of the total energy consumption and second largest portion of the total water consumption (excluding urban use) nationally. Water and energy efficiency improvement is becoming imperative for organisational success as well as national economic sustainability. This is due to the significant increase in the cost of both electrical energy and water in recent years, and the drop in the reserve energy margin below the minimum level required for sustainable operation of energy utilities. The research objective therefore was to develop a Lean-based water and energy efficiency improvement framework for the manufacturing industry to encourage and realise a reduced demand for energy and water in it. A literature review was conducted on the water and energy landscape in South Africa, Lean manufacturing principles and their positive natural influence on water and energy efficiency, and the Value Stream Mapping tool. The survey of water and energy wastes in the manufacturing industry yielded the creation of standardised water and energy waste categories for use in conjunction with the conventional Lean wastes, tools and techniques. The literature survey indicated that the implementation of Lean manufacturing techniques naturally leads to the improvement of energy and water intensity. The researcher hypothesised that there is even greater potential for water and energy savings if a Lean-based tool is developed to specifically focus on the improvement of energy and water efficiency. A framework for this tool was developed through the literature survey. The tool is based on the Value Stream Mapping tool. A practical experiment was then conducted to establish the effectiveness of the tool in the South African manufacturing industry. The experiment design included an outline of the forecasting and statistical validation techniques to ensure the integrity of data utilised for approving or disproving the set hypotheses. The results of the practical experiment yielded positive results, confirming the hypothesis that the implementation of the developed framework will lead to improved energy and water efficiency in the manufacturing industry. After an explanation of the experimental results, the study concluded with recommendations and conclusions based on the findings.

National Centre for Nano-Structured Materials (NCNSM), one of the National Department of Science and Technology’s nanotech innovation centres houses a characterisation facility which provides a wide array of high-tech materials characterization techniques used in nanotechnology research, to any researchers from any part of South Africa, whether from higher education institutions, government institutions or private firms. In this study the operational review was conducted to identify if the NCNSM Characterisation Facility is delivering on its implementation intent. With operational review organisations are able to explore their internal operations and seek recommendations as to how they can manage and operate more economically, efficiently and effectively. Given that they perform appropriately, allocating their resources properly, and performing within time frame set and using cost-effective measures. BPR was used as a framework to conduct the operational review. BPR is a framework for analysis and design of workflows and process within an organisation. It is an improvement initiative that provides radical change of the business processes in an organizational process. The findings of this study indicated that the NCNSM-CF did not entirely meet its implementation intent but it is striving towards the intention. One of the main reasons for the facility not to meet its intended implementation was the difficulty of the researchers/clients to get access to the facility. The current booking system process contributed significantly to the access problem.

A research report submitted to the Faculty of Engineering and the Built Environment, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the Degree of Master of Science in Engineering, October 2015 / A single case study of a major third party logistics provider (3PL) in South Africa was completed for this research. A total of four warehouses, including 43 workers partook in the study. The primary objective of this research was to determine how well employees within the warehousing industry understand Lean principles, and to illustrate the gap in Lean knowledge between the employment levels, i.e. Managers, Supervisors and Material Handlers. Group-administered questionnaires were used as the principle means of gathering data. All participants for each respective warehouse were present in a “classroom” format during completion of the questionnaires. The author was also present during all sessions to ensure consistency and to clarify any questions that participants had. The questionnaire tested each participant’s understanding with regards to seven key Lean principles in warehousing. These seven principles were identified from previous research on Lean within warehousing. The results gathered from the questionnaires were then validated using semi-structured follow-up interviews. It was found that a real gap in Lean knowledge exists between Managers and Material Handlers (shop-floor workers). Managers understand the key Lean principles within warehousing, as well as the importance thereof. While the employees actually working on the floor do not. The main reasons for this are due to a lack of suitable training and knowledge sharing. Based on the seven key Lean warehousing principles, the following were identified in the study as the most important ones to focus on: Continuous Improvement and Visual Management. These are believed to be basics in warehousing. However, employees still seem to struggle with the true understanding and significance thereof. It is imperative that the understanding of Lean principles and the involvement of management exist when striving to be successful with Lean. The gaps in Lean knowledge have been identified and laid out in this report. The reasons for each gap have also been investigated and discussed in detail. Finally, pertinent areas have been highlighted to assist with the development of Lean training material. This will ensure that the current gap of Lean understanding among warehousing employees is closed.

Submitted in fulfilment for the requirements of the degree of Master of Technology: Business Administration in the Faculty of Management Sciences at the Durban University of Technology, 2009. / Competition is increasing as trading borders continue to widen in this global marketplace. As a result, South African organisations need to improve their efficiencies. The primary objective of the study was to examine the effectiveness of the Lean Enterprise Strategy (LES) at improving business efficiency, in the electrical pre-payment industry in KZN. Several underlying objectives which support the primary objective were examined and realtionships established. Two forms of empirical studies, observation and questionaire based, were used. These studies provided substantive findings which were analysed and interpreted. A positive relationship between the LES and business efficiency were established and the various underlying objectives addressed. Communication was found to be inadequate and highlighted. It was also found that there is a substantial delay in return on investments; therefore, sustainability should be targeted and the LES should have a continual re-cycling mechanism, which allows it not only to be sustainable, but also renewable.
