- Description: M.Ing. (Engineering Management) , Business Process Reengineering (BPR) is intended to be a management initiative that fundamentally redesigns business processes, through radical rethinking of core business processes. Thus ultimately yield dramatic improvements in contemporary performance measures such as quality, service, speed etc. Business processes are driven by people, technology, and workflow, however very little has been mentioned about the “people element” in reengineered processes literature. Hence the estimated failure rate of 70% in reengineering initiatives partly results from neglecting the human element in redesigned processes. The report is aimed at dealing with the “human element” in BPR through the introduction of the concept referred to as Business Process Reengineering Management (BPRM). A number of BPR case studies were used to develop the concept of BPRM. Case study findings in both successful as well as unsuccessful BPR initiatives were analysed, and the concept of BPRM was then deduced from both the case studies as well as the literature review.

- Description: Abstract: With ever increasing concerns about the type of planet that generations to come stand to inherit, Life Cycle Assessment initiatives are carried-out to quantify the amount of impact that different sources of pollution have on the environment. Life Cycle Assessments have evolved over the last few decades, and the paper primarily focuses on what have been achievements, areas of improvement, barriers, and what still needs to be done to ensure that scares natural resources are preserved for future generations.

- Description: Abstract: Africa has launched a Life Cycle Assessment (LCA) network in conjunction with the Society of Environment Toxicology and Chemistry (SETAC), and this points to a recognised gap in LCA initiatives between developed and developing countries. Although South Africa does not have legislation on carrying-out LCA initiatives, there is a huge drive on preserving our environment, and that is evidenced through the carbon tax bill already proposed. It is due to such developments that the authors initiated an LCA initiative in the design phase of a Biogas Plant for domestic applications. Thorough LCA initiatives are notorious for being time consuming and often manipulated by organisations to “greenwash” their products. These challenges have been a stumbling block for the acceptance of LCA initiatives. The paper looked at the operation of a biogas digester process, for a biogas digester that has been developed in the University of Johannesburg. From the aforementioned process fundamental Life Cycle computation was carried out to identify the environmental impact of the product. The study seeks to encourage the concept of Design for Environment (DfE), and in addition raise awareness on the ever increasing demand of eco-friendly engineering solutions.

- Description: Abstract: Uncertainties in Life Cycle Assessment (LCA) initiatives play a major role in influencing government policies and corporations strategic plans. Thus it is important to ensure that the models of LCA initiatives are modeled such that they resemble emissions in the real world. In the paper the authors have reviewed the uncertainty tools used in LCA initiatives. This is conducted in hopes that LCA modelers understand the limitations and advantages associated with LCAs, and also identify areas where they can refine their data. In an event where there is a shortage of data, conservative means which can be used to approximate data to best model the effects of Global Warming in the real world are discussed.

- Description: Abstract: Business Process Reengineering (BPR) or simply reengineering is an initiative undertaken by organisations that seek to fundamentally redesign their existing business processes. In the current business landscape, the only constant is change; hence organisations should always strive to conduct their businesses effectively and efficiently. However reengineering has not always yielded fruitful results, as indicated by the 70% of the initiatives that have failed. The failure rate of the reengineered initiatives partly results from neglecting the “human element” involved when revising processes. Literature has not dealt extensively with how stakeholders react towards dramatic change brought about by reengineering, and the current paper is primarily concerned with this issue, through the proposal of the Business Process Reengineering Management (BPRM) concept.
