- Description: M.Phil. (Engineering Management) , Abstract: Infrastructure is one of the main agents for economic growth, infrastructure supports the improvement of a nation the people. This is more noteworthy in developing countries, countries with less developed infrastructure suffer from missed opportunities and business. Building roads, schools, airports, power stations and water treatment facilities will not only empower the country’s economy and socioeconomics but will provide sustainable jobs for the country. However, the civil construction industry is known for its time and cost overrun which can damper the progression of economic growth of a country. There are investments being wasted in the civil construction projects caused by varies issues and these issues differ from projects. The research investigated the application of agile methodology in the design phase of a civil construction project to mitigate challenges and improve the delivery in the design phase. The research conducted a literature review to get the background knowledge and to have a broader understanding of the problem and solution method. The search than conducted a systematic literature review where the guidelines, procedures, of the Cochrane Handbook for Systematic Reviews of Intervention, was used. Following the systematic literature rigorous procedure, the final studies that were collected amounted to 22 out of the 2440 studies. The 22 studies were analysed using thematic analysis, from conducting the analysis it found four themes for challenges in the design stage of a project, which are 1) Schedule overrun 2) Construction Waste management 3) Design Performance 4) Project Management. Applying agile methodology on the challenges indicated that the methodology can have an improvement in the design stage of a civil engineering project, by increasing transparency and adding value to the project, utilizing time management and increasing both the client’s contribution and the team’s morale this factor and much more from agile approaches can improve the delivery of the design phase.

- Description: Abstract: The National Department of Public Works and Infrastructure (NDPWI) has the mandate from parliament to provide accommodation (buildings) and other infrastructure to some public service departments (clients). These clients include the South African Police Services (SAPS), Department of Defence (DOD), Department of Justice and Constitutional Development (DOJ & CD), Department of Correctional Services (DCS) and Department of Home Affairs (DHA). However, it has been observed that considerable time is expended between project briefing and actual delivery of the infrastructure, resulting in time and cost overruns. Therefore, it has become necessary to evaluate the current project delivery process, with a view to identifying the causes of delay and proffer solutions on how to improve project delivery within the iron triangle of cost, time and quality, as well as to improve on customers’ satisfaction. A multiple site case study method of qualitative research was adopted. The Delphi technique, a method of consensus building, was used for data collection and analysis. The data are collected in iterative processes and distil the judgments of participants using a series of questionnaires interspersed with feedback. The participants, commonly referred to as experts or knowledgeable persons, are purposively selected within predetermined qualification criteria. The participants for this research were officers at the strategic and tactical levels of leadership, not lower than the rank of Engineer or Architect and must have spent at least five years in the respective office. Seventeen (17) participants who met the pre-qualification criteria where drawn from three zonal office of the NDPWI in Kimberley, Cape Town, and Bloemfontein as well as the Professional Services division in the Head office. The Focus group (FG) session was used to complement the results from the Delphi exercise. Eight (8) participants, among those who participated in the Delphi exercise, accepted the invitation to take part in the FG. First, they validated the findings from the Delphi exercise, x-ray the root causes to the problems identified and develops practical solutions... , M.Ing. (Engineering Management)

- Description: M.Phil. (Engineering Management) , Abstract: Supply chain (SC) is an integrated process of various business functions used, to source raw material, add value to the raw material, and deliver the product to the customer. The common element to all manufacturing entities is the control of material flow, value adding (manufacturing) processes, and distribution channels to customers. With the ever-increasing competitive environment, many manufacturing companies around the world, including those in South Africa, experience a shortfall in the desired outcomes. As a result a number of organizations have looked at a possible mechanism to put in place to maintain or gain the competitive advantage, or to maintain or increase market share. Industry maturity saw a number of organizations implement the use of Supply Chain Management (SCM) in order to try to minimize costs, increase profits, and meet customer expectations, i.e. on time in full delivery (OTIFD) of a product or service against contractual or negotiated dates and in accordance with the customer requirements (Quality). This research examined the factors that affect the performance (on-time delivery) of a manufacturing supply chain. Two research questions had to be addressed to reach this goal:- (i) What are the factors affecting the on-time-delivery of the supply chain? (ii) What is the impact of these factors on the supply chain and the organization? In addition to the data collected from literature, two other data sets were collected for this research. Operational data were collected from a performance management tool (Qlikview) and the other set of data was collected through interviews with the use of a questionnaire. Both sets of data were analysed to identify any common patterns when it comes to the factors that affect the performance of supply chain. The results of the analysis suggest that the factors that contribute the most to poor supply chain performance are social factors. There is also an indication that there is a relationship between internal deliveries and customer deliveries...
