There are two popular approaches when developing a software system, the first being System Analysis/System Design (SA/SD) and the second being an Object-Oriented (00) approach. In either approach a poor design inevitably produces a poor application. Thus, being able to evaluate the quality of a systems design is advantageous.The Design Metrics Research Team at Ball State University has developed metrics that measure the quality of software systems. From this research the metric D(G) (a composite of the metrics De and D) has been shown to be very effective when used to determine fault prone modules in a system. However, D(G) has been primarily applied to systems developed using the SA/SD approach. This thesis translated D(G) to an 00 setting and empirically evaluated D(G) to determine if D(G) is a good predictor of error-prone classes. The results indicate that De and Di are indeed good predictors of error-prone classes. Of the classes highlighted by De, 67% had errors, while 100% of the classes highlighted by D; had errors. / Department of Computer Science

There exist a number of well-known and validated design metrics, and the fault prediction available through these metrics has been well documented for systems developed in languages such as C and Ada. However, the mapping and application of these metrics to SDL systems has not been thoroughly explored. The aim of this project is to test the applicability of these metrics in classifying components for testing purposes in a large-scale SDL system. A new model has been developed for this purpose. This research was conducted using a number of SDL systems, most notably actual production models provided by Motorola Corporation. / Department of Computer Science

This study provides information on the effectiveness of design metrics when used on object oriented systems and explores means of increasing metric use-fulness in regard to the problem areas identified. Evidence shows that current metrics are weak in assessing some qualities when faced with concepts central to object orientation. It describes practices in design and implementation that cause complications in calculating metrics and what effects those practices may have on various types of metrics by examining specific examples as well as discussing the theory involved. It examines assumptions which can be made in the formulation of metrics to avoid the issues caused by these practices and what effect these assumptions will have on metric results. / Department of Computer Science

A critical component of software development is the process whereby the software requirements of users and stakeholders are established. This process is referred to as the Requirement Elicitation (RE) process of software development. The high rate of failed, cancelled or unsuccessful projects due to not meeting user requirements may be attributed to insufficient focus on the RE process. This case study investigates the relationship between the type of RE technique used and the success of an information system at a global petrochemical company based in South Africa. The end user involvement during the software development life cycle (SDLC) and the acceptance of the resultant information system was also examined. Three information systems (IS) projects that employed different RE techniques were selected for the purpose of this study. An electronic questionnaire was disseminated to a randomly selected representative sample from the user community for each system in order to obtain feedback with regards to the success of the system from the user’s perspective. The study adopted the strategy of focusing on end user acceptance of each information system as a pivotal contributory factor to information system success. In this regard, the Technology Acceptance Model (TAM) model was used to operationalize user acceptance of each information system that formed the focus of the study. For each IS project, the quantitative dimension was extended to include a qualitative aspect that entailed structured interviews with the business analyst (BA) and project manager (PM), with the primary purpose of ascertaining the RE strategy used for the development of each system. The interviews also served the purpose of providing the researcher with an opportunity to obtain a deeper insight into the logistics of system development. The results of the study indicated that planned, user intensive RE techniques resulted in greater system acceptance by the end users of the respective systems. A significant outcome of the study is that there is a strong correlation between the amount of end user involvement in the SDLC process and the success of the information system. A converse of this trend was also noted. When users have systems imposed on them, this results in lower satisfaction levels as a consequence of poor system usability and a lack of confidence in the value that the system provides for the end users. / Thesis (M.Com.)-University of KwaZulu-Natal, Pietermaritzburg, 2013.

Web applications have become a large segment of the software development domain but their rapid rise in popularity has far exceeded the support in software engineering. There are many tools and techniques for web application development, but the developer must still learn and use many complex protocols and languages. Products still closely bind data operations, business logic, and the user interface, limiting integration and interoperability. This thesis introduces an innovative new presentation service to help web application developers create better applications faster, and help them build high quality web user interfaces. This service acts as a broker between web browsers and applications, adding value with programming-language independent object-oriented technology. The second innovation is a generic graphics applet (GGA) component for the web browser user interface. This light component provides interactive graphics support for the creation of business charts, maps, diagrams, and other graphical displays in web applications. The combination of a presentation service program (BUS) and the GGA is explored in a series of experiments to evaluate their ability to improve web applications. The experiments provide evidence that the BUS and GGA technology enhances web application designs.

The present study has originated from the realisation that numerous software development projects either do not live up to expectations or fail outright. The scope, environment and implementation of traditional software projects have changed due to various reasons such as globalisation, advances in computing technologies and, last but not least, the development and deployment of software projects in distributed, collaborative and virtual environments. As a result, traditional project management methods cannot and do not address the added complexities found in this ever-changing environment. In this study the processes and procedures associated with software project management (SPM) were explored. SPM can be defined as the process of planning, organising, staffing, monitoring, controlling and leading a software project. The current study is principally aimed at making a contribution to enhancing and supporting SPM. A thorough investigation into software agent computing resulted in the realisation that software agent technology can be regarded as a new paradigm that may be used to support the SPM processes. A software agent is an autonomous system that forms part of an environment, can sense the environment and act on it over a period of time, in pursuit of its own agenda. The software agent can also perceive, reason and act by selecting and executing an appropriate action. The unique requirements of SPM and the ways in which agent technology may address these were subsequently identified. It was concluded that agent technology is specifically suited to geographically distributed systems, large network systems and mobile devices. Agents provide a natural metaphor for support in a team environment where cooperation and the coordination of actions toward a common goal, as well as the monitoring and controlling of actions are strongly supported. Although it became evident that agent technology is indeed being applied to areas and sections of the SPM environment, it is not being applied to the whole spectrum, i.e. to all core and facilitating functions of SPM. If software agents were to be used across the whole spectrum of SPM processes, this could provide a significant advantage to software project managers who are currently using other contemporary methods. The "SPMSA" model (Software Project Management supported by Software Agents) was therefore proposed. This model aims to enhance SPM by taking into account the unique nature and changing environment of software projects. The SPMSA model is unique as it supports the entire spectrum of SPM functionality, thus supporting and enhancing each key function with a team of software agents. Both the project manager and individual team members will be supported during software project management processes to simplify their tasks, eliminate the complexities, automate actions and enhance coordination and communication. Virtual teamwork, knowledge management, automated workflow management and process and task coordination will also be supported. A prototype of a section of the risk management key function of the SPMSA model was implemented as `proof of concept'. This prototype may be expanded to include the entire SPMSA model and cover all areas of SPM. Finally, the SPMSA model was verified by comparing the SPM phases of the model to the Plan-Do-Check-Act (PDCA) cycle. These phases of the SPMSA model were furthermore compared to the basic phases of software development as prescribed by the ISO 10006:2003 standard for projects. In both cases the SPMSA model compared favourably. Hence it can be concluded that the SPMSA model makes a fresh contribution to the enhancement of SPM by utilising software agent technology. / School of Computing / Ph. D. (Computer Science)
