- Description: M.Ing. (Engineering Management) , Requirements engineering forms an integral part of software engineering. The purpose of requirements engineering is to provide high quality requirements for a system or solution. These requirements are then utilised by developers to produce a high quality system. They also assist project managers to better plan the schedule and costing of information technology projects, resultinq in cost savinqs. The problem is that although formal definitions and processes do exist for requirements engineering, projects are still failing due to the poor quality of requirements, This study investigates this phenomenon, in particular to understand why project teams cannot deliver high quality requirements. This is done against the background of the processes and standards available to organisations. The root cause of the problem is researched to determine whether the processes are the cause or whether other factors are contributing to poor quality requirements. This study makes use of two cases within one organisation to determine what the contributing factors are with regard to poor and good quality requirements. The cases provide information on why one project delivered good quality requirements and another project within same organisation, the same business unit, with the same support structure, delivered poor quality requirements. It is perceived that the case study method was a valid method in this particular research study as it provided the researcher with in-depth knowledge and observations on how organisations deal with the process of requirements engineering. It was found that the quality and clarity of communication or the lack thereof plays a significant role in the quality of requirements. This research provides an alternative view on the factors contributing towards poor quality requirements. This implies that organisations can train or educate requirements engineers in communication skills. The skill of communication allows a requirements engineer to create a trust relationship with customers, and this empowers him/her to elicit good quality requirements from the users.

- Description: M.Ing. , This research study is about evaluating the practicability of using systems engineering approach to rural electrification project risk management. The research was motivated by rural electrification projects in South Africa that have suffered planning, design or operational problems due to uncertainties at project site level. The dissertation begins by describing the rural electrification background in the first chapter. The process of electrifying rural areas, challenges, and achievements so far in South Africa are presented. The government target for universal access to electricity is also highlighted. The next two chapters address the theory of systems engineering, and project risk management as one of the elements of project management. The theory of systems engineering approach to risk management is then applied to a typical electrification project structure. The electrification project is viewed as a system, with risk management as a sub-system of project management. A case study is presented for a rural electrification project in KwaZulu-Natal that has experienced design and operational problems. A risk system is identified from work breakdown structure, and risk hierarchy framework is produced based on project life cycle cost model. Risks are ranked in terms of their impact and probability. The aim of the study is to understand the impact of each risk on general project risk, and risk mitigation measures that should be taken to address those risks. The research finishes by drawing a conclusion that electrification projects are complex, risks are manageable, and systems thinking can be successfully used to manage electrification project risks. Risk management must focus on the project as a whole, including operation and maintenance, rather than focusing at individual project stages.

- Description: With the exponential increase in the complexity of modern products, the enterprise which creates the product also increases in complexity. Projects to realise engineering products are often fraught with delays, budget overruns and unsatisfied clients. The study sets out exploring the domains of systems engineering, project management and quality management, by extensively referencing industry standards and international good practice in the quest of unravelling conflicts and uncertainties. Selected concepts and business processes of each domain are studied to arrive at an understanding of the objectives and scopes of those processes. This understanding enables the integration of these business processes and concepts by utilising the widely‐used plan‐do‐check‐act (PDCA) cycle. The business processes of each domain are divided into the four PDCA quadrants and integrated models of those quadrants are presented. The four quadrants are synthesised into a single framework which shows the project management, quality management and systems engineering processes performed during a single project phase. This Engineering Management Framework may be tailored for the design and realisation of any complex product, given adequate planning, understanding of the challenges and knowledge of the subject matter.

- Description: M.Ing. , The aim of this research is to develop a Project Management Maturity Measurement Model to evaluate project management efficiency in a large Parastatal such as Eskom Distribution. This model will identify areas of improvement to assist a large Parastatal in improving their project management performance. It will eventually assist the organisation to build a culture of project management excellence. The hypotheses for the study were that firstly, the Parastatal does implement project management practice processes as advocated by project management bodies of knowledge. Secondly, a Project Management Maturity Measurement Model can be successfully implemented at a large Parastatal and help the Parastatal to identify project management grey areas that require improvement. Thirdly, a Project Management Maturity Measurement Model could assist a large Parastatal with project management improvement as a result of areas of recommendations. The method used to collect the required data for analysis and interpretation was the descriptive survey method. A customised survey questionnaire was developed to obtain data from research sample. Data was analysed using appropriate statistical techniques. The research sample was defined as the people who are primarily responsible for project, programme and portfolio management at a large Parastatal. The results of the data analysed pin pointed project management process weaknesses and possible improvement opportunities. Three main areas of improvement have been identified, namely applying lessons learned from previous project into future project, performing benchmarking to improve performance and project control processes. The findings of this study support the abovementioned hypotheses, and the insights provided and recommendations made will be of great help to a large Parastatal on its road to continuous improvement and building a culture of project management excellence.

- Description: M.Ing. , The A-Darter integration on the JAS39 Gripen was a very unique program in the sense that the development of the A-Darter missile was still on going when the integration took place. This dissertation thus looks at the various activities that were necessary when doing an integration program of such a nature. Firstly a well-defined contract needs to be in place in order for the various parties to understand their roles in the program. A Statement of Work (SOW) also needs to be defined together with this contract; the minimum that should be considered is as follows: - Management - Operational Analysis - Aeronautical / Airframe Integration - Systems Integration - Flight Test and Verification - Integrated Logistics Support (ILS) The systems engineering process is also described in this mini dissertation; both the SAAB Product Development Process (PDP) as well as the INCOSE System Engineering Processes are described. The dissertation describes when and where in the process an integration process can take place and what the minimum requirements are. The logical flow is described in terms of the critical path that needs to be followed during the integration process. The dissertation describes the process from the physical fitment trials that need to take place to the final launch of the System Avionics Test Missiles (SATM). The risks and lessons learnt are also described in this mini dissertation, the input for these sections were from interviews of people who were critical in the success of the program. The major risks on the program were definitely the technological risk as two state of the art pieces of equipment needed to be integrated. Power requirements and adherence to MIL-STD 1760 were one of the other main risks. The vibration spectrum that Denel Dynamics had to comply to also proved a risk in the program. However all the risks were mitigated and hence did not have an impact on the program.

- Description: M.Phil. (Engineering Management) , With the current global political and economic environments, there is a lot of economic fluctuation and uncertainty in the world markets. This results in the instability of prices for goods and other products. And since we operate in a globalised era, this has a direct impact on the life cycle costs of many systems and products. Experience has indicated that a large portion of the total cost of many systems is as a direct result of activities associated with the operation and support of these systems and products, while the commitment of these costs is based on decisions made in the early stages of the system life cycle (Blanchard, 1990:505 & Blanchard, 2004:24-26). Further, the various costs associated with the different phases of the life cycle of a system or a piece of equipment are interrelated. Thus, in addressing the economic aspects of a system, one must look at the total cost in the context of the overall life cycle, particularly during the early stages of conceptual design and advanced system planning. Life cycle cost, when included as a parameter in the systems engineering process, provides the opportunity to design for economic feasibility. To address these aspects the following questions are answered through the research: What are life cycle costs and what are the benefits of costing them? When and where are costs incurred in a systems life cycle? What are the key variables in establishing life cycle costs? How can these variables be better defined to ensure that the life cycle costs are sustained through the entire life of a system? Can the engineering inflation be defined and be used instead of the general inflation rate? Now the challenge is that with the fluctuating economic conditions mentioned earlier, one cannot predict the life cycle costs of a system as closely accurate as is required. The proposed research focused on identifying sustainable measures to ensure that life cycle costs remain relevant through the lifespan of a system or equipment.

- Description: M.Ing. (Electrical Engineering) , Abstract: Successful projects are those that meet business requirements, are delivered and maintained on schedule, are delivered and maintained within budget and deliver the expected business value and return on investment. CE (Community Engagement) projects that are engineering focused, rely on the same strategy of success. However, there are a number of CE projects that fail due to a number of factors such as a lack of funds to finance operations and purchase resources required for the project, poor management of resources and finances, poor management of the overall project, lack of youth involvement in community-based project, lack of monitoring and evaluation of community projects and lack of stakeholder participation. Furthermore, CE projects conducted by engineers can suffer while being conducted due to the poor approach of engineers to such projects. Engineers believe in problem solving through the standard “hard” engineering approach. However, this approach frequently ignores the social aspects within these projects. It was deemed necessary that in order to prevent CE projects (that are engineering focused) from failing, to target the root of the cause by encouraging engineering institutions to incorporate CE projects as part of the curriculum. This would cultivate engineering students into ‘community engaging experts’ and allow students to gain a “hands on experience” by physically participating in engaging projects and interacting with communities. Therefore, it was hypothesised that the design and implementation of a CE framework, (CEF) designed for engineering institutions will assist in the successful conducting of CE projects and also allow for student teams to socially interact with communities and physically engage in these projects. The CEF was integrated with systems engineering, project management and CE literature. The framework was built off the (South Africa National Standard) SANS-15288 Systems Life Cycle standards and incorporated processes from project management theory and CE theory, such as work breakdown structures and community selection procedures. The framework was tested on an existing CE project (conducted by The University of Johannesburg), called The Gwakwani project, which ended off successfully with phase 1 in 2014. Phase 2 included the design and installation of a system solution to solve the community’s lighting dilemma. The installation of individual solar lighting units and the donation of hand held solar lighting units (sponsored by Schneider Electric), encompassed this community service initiative. The implementation was tested and evaluated based on the project procedure and whether individual stakeholder requirements were met. The evaluation consisted of a survey analysis (through indicators) and the received data was analysed statistically. The survey revealed information of firstly the implementation of the lighting units and secondly determined the validity of the framework through implication.

- Description: M.Phil. (Engineering Management) , Abstract: The global industry has already gone through three documented changes in its entire existence. These documented changes are referred to as industrial revolutions. The First Industrial Revolution was influenced by the use of steam in industry. The Second Industrial Revolution was influenced by the use of electricity in industry. The Third Industrial Revolution was influenced by the use of Information Technology (IT) in industry. The global industry is currently going through the Fourth Industrial Revolution, at a different pace in different parts of the world. The Fourth Industrial Revolution is influenced by the advancement of technology and a drive towards autonomy in industry. Sometimes referred to as Industry 4.0, the Fourth Industrial Revolution presents exciting opportunities and challenges for the future work environment around the world. These opportunities and challenges include but are not limited to the required competencies for the professionals of the future. The change in required competencies is brought upon by the Industry 4.0 technologies such as Cyber-Physical Systems, Internet of Things and Smart Factory. These technologies should be thoroughly understood by the future workforce in order to be implemented properly. The concept of autonomy presents complex system automation design and complex system integration requirements, both directly linked to a control systems engineer. The problem posed by this change to a control systems engineer is, therefore, the need to acquire the necessary competencies required to implement these technologies. In light of this, this current research study aims to identify the required Industry 4.0 competencies for a control systems engineer. In identifying the required competencies for a control systems engineer, this current research study filters through existing Industry 4.0 literature. By so doing, this current research study summarizes what is currently researched throughout the world in regard to the required competencies of a control systems engineer, facilitating a competency gap analysis between...

The Second Industrial Revolution was influenced by the use of electricity in industry. The Third Industrial Revolution was influenced by the use of Information Technology (IT) in industry. The global industry is currently going through the Fourth Industrial Revolution, at a different pace in different parts of the world. The Fourth Industrial Revolution is influenced by the advancement of technology and a drive towards autonomy in industry. Sometimes referred to as Industry 4.0, the Fourth Industrial Revolution presents exciting opportunities and challenges for the future work environment around the world. These opportunities and challenges include but are not limited to the required competencies for the professionals of the future. The change in required competencies is brought upon by the Industry 4.0 technologies such as Cyber-Physical Systems, Internet of Things and Smart Factory. These technologies should be thoroughly understood by the future workforce in order to be implemented properly. The concept of autonomy presents complex system automation design and complex system integration requirements, both directly linked to a control systems engineer. The problem posed by this change to a control systems engineer is, therefore, the need to acquire the necessary competencies required to implement these technologies. In light of this, this current research study aims to identify the required Industry 4.0 competencies for a control systems engineer. In identifying the required competencies for a control systems engineer, this current research study filters through existing Industry 4.0 literature. By so doing, this current research study summarizes what is currently researched throughout the world in regard to the required competencies of a control systems engineer, facilitating a competency gap analysis between...

- Description: M.Ing. , The topic of this research project is 'Assessment of value added to engineering projects'. In this dissertation the aim is to introduce the reader to the methodologies, which can be used to add value to engineering projects. Engineering has to do with the application of science in solving problems, while technology is the study or use of the mechanical arts or applied sciences. The author saw it fitting to combine value engineering principles, systems engineering, business process re-engineering, technology scanning and innovation technology management principles to base this dissertation on the research of the combined principles. The intention of this research is not to replace the current project management or processes on how to manage and create value in engineering projects. The research merely identifies an issue and proposes a process as an addition to the current processes rectifying this 'lack of value' issue.

- Description: Abstract: Automation systems in long steel products hot rolling plants are prone to performance failures with the potential of serious negative impact on the business. The selection process of these automation systems therefore requires careful consideration of various selection factors to maximize plant performance. The need was therefore identified to investigate the use of a suitable management approach to guide engineering automation teams in the long steel products hot rolling plants in the selection of automation systems. At the core is the need for an in-depth understanding of the issues surrounding distributed and hierarchical automation systems in long steel products plants. This includes identifying the challenges during the selection process, using sound engineering management principles. Current automation selection techniques were investigated through a survey, interviews and a case study. It was then decided to use a Model Based Systems Engineering (MBSE) approach, which utilises systems engineering principles together with digital technology to create models to simplify the understanding of complex problems and relationships. This was then used to develop a management framework for automation systems selection in support of the business case of long steel products hot rolling plants.
