The need for information systems has increased to a point where virtually all business environments require some sort of software to aid in its daily operations. This study will address the need for quality information systems by examining techniques which can potentially aid in producing consistent high-quality information systems. Two techniques in particular, namely Process Maturity Models (PMMs) and Systems Development Methodologies (SDMs) are examined. Process Maturity Models such as the Capability Maturity Model Integration (CMMI) as well as the ISO-9000 standards aid in standardising and improving an organisation’s information systems development processes. These Process Maturity Models often require either the use of certain Systems Development Methodologies or at the very least techniques used within some Systems Development Methodologies. Systems Development Methodologies refer to a set of development processes, tools, techniques etc. which can be used during software development to standardise the entire development process by offering the use of modelling techniques, tools to analyse requirements, illustration of processes etc. These techniques differ from one Systems Development Methodology to the next. This study aims to identify the relationship between Process Maturity Models and Systems Development Methodologies. During the research process a questionnaire was sent out to people within the information technology business environment. The questionnaire contained questions used to determine and measure the usage of Systems Development Methodologies and how projects were affected. The questionnaire was also used to do an informal assessment of each respondent’s Capability Maturity Model level. Furthermore the data retrieved was statistically analysed and the results were interpreted. The results indicate that a relationship exists between the use of SDMs and the success of the respondent’s development processes and developed products. A total of 73% of respondents indicated that they do use SDMs to some extent, the most common being the Systems Development Lifecycle (SDLC). The majority of organizations implementing SDMs have been doing so for three years or more. Results also show that most of the respondents are not certified in some formal Process Maturity Model; however, they do implement some of the processes required by models such as the CMMI. An informal assessment performed indicated that 65% of respondents can be grouped into a perceived CMMI level 2 category. Project outcome was measured and the relationship between PMM implementation as well as SDM use was measured. Results show no statistical evidence which indicates that an organisation’s perceived CMMI level is influenced by SDM use, both vertically and horizontally. Results do, however, indicate that organizations which have been implementing SDMs for a longer period of time are more likely to apply CMMI level 4 activities. Results also indicate that the horizontal use (number of projects/people which implement SDM knowledge) of SDMs have a significant effect on the development process- and the developed product success. Lastly the results indicated that organizations which satisfy more of the CMMI’s level 4 activities experience a higher quality development process which leads to a more successful development process. / Thesis (MSc (Computer Science))--North-West University, Potchefstroom Campus, 2013.

A substantial amount of IT projects fail or stay challenged in meeting their targets based on project schedule, budget and system requirements.  Leading global surveys in the last decade barely indicate any improvement in the statistical performance of IT projects in spite of the fact that a lot of effort has been taken in the past to identify and fix those critical factors on which the success and failure of IT projects are generally based on. The poor trend and the underperformance of IT projects still continue. Different researches based on different approaches identify different critical factors but to a very large extent people and processes are blamed. This thesis is under taken to understand the impact of Information Systems (IS) processes and methodologies in the success and failure of IT projects. Major challenges within IS processes, such as their initial identification, implementation and organizational process awareness are identified through qualitative research methods. ‘Identification and selection of IS process and methodologies’ is identified as a major challenge within IT projects and is discussed in detail as, why and what difficulties organizations face in the process of  selecting processes and methodologies on a given IT project. A couple of methodology selection frameworks to overcome these difficulties are presented along side with their critical review and improvement. We come to a conclusion that there is a growing need for more efficient and competent methodology selection frameworks as the ones which exist today are barely complete and efficient and if they do then only to a limited and partial degree.

In the last few years the demand for organic products has increased rapidly resulting in a strong growth of the organic industry worldwide. Organic certification is globally used to guarantee that 'organic' labelled produce follow the principles and standards of organic agriculture set by international and national organic certification bodies. Currently the lengthy and complex process of organic certification is entirely paper based and requires multiple access by organic primary producers to the certifying body involving precise data capture and transfer over a long period of time. The paper based organic certification has some significant disadvantages such as being time-consuming, error-prone (in particular transcription errors) and complex. Any improvement of the paper based organic certification process can lead to higher efficiency, lower costs and time savings for primary producers and certifying bodies. Australia is a major supplier of organic produce holding almost half of the organic farmland worldwide. However, Australia?s unique geography provides challenges by means of huge distances and poor rural telecommunication coverage for the sustainable agriculture sector. The disadvantages of the paper based organic certification are this kind of environment more severe. Up until now, there has not been a software solution supporting organic primary producers in their certification process, let alone a mobile software solution. In any case there are many farm management software solutions available but they do not take into account the specific issues in organic agriculture such as soil management, pest control, or fertilisation of land/animals. The Mobile Organic Certification (MobiCert) project was created to overcome these disadvantages focussing on the development of a mobile information portal which can be accessed through mobile Internet using GPRS or 3G technology enabling primary producers access and provision to organic certification related information in field using their mobile phones. The MobiCert project investigates the effectiveness of mobile devices (mobile phones/PDAs) for (some of) the stages of the computerised organic certification, in particular in terms of information access and provision. Designed as a proof-of-concept project the investigation takes place in South Australia targeting the NASAA organic certified primary producers there. The MobiCert project is a pilot project within the SAmCom (Sustainable Agriculture m-Commerce) project framework, which aims to enhance the information access and provision for primary producers through m-Commerce. It is a joint project of the University of South Australia, m.Net, NASAA, e-Cert and the Fraunhofer Institute Using a qualitative approach in a rapid appraisal case study the goals of the MobiCert project are: to create a theoretical model (RuTADIM) for the mobile technology acceptance and diffusion of innovation in remote and rural areas; and to develop and test a prototype mobile information community for organic certification which provides access to data and information related to organic certification, (online and offline) record keeping functionalities, as well as community functionalities for communication and experience exchange of primary producers. The results of the proof-of-concept MobiCert project suggest that organic primary producers can benefit from a mobile information platform to access and provide information in rural and remote areas. The high acceptance of organic primary producer to use the mobile information community indicates the willingness to embrace new technology and solutions in the existing organic certification process. The benefits and acceptance of the MobiCert solution have to bee affirmed in follow on field studies incorporating other issues such as the underlying business models. The contributions of the MobiCert project are two-fold: firstly, it provides a theoretical model (RuTADIM) which gives insights of key influence factors for the acceptance of mobile technology and the diffusion of innovation in rural and remote areas. The RuTADIM model can be foundation for future research projects involving mobile technology rural and remote areas. Secondly, the MobiCert information community displayed the potential of mobile solutions for primary producers in remote and rural areas. The MobiCert platform is a stepping stone for future mobile solution which can build upon this platform.

Esta perspectiva abrange o entendimento sobre os mecanismos da gestão do conhecimento e o papel dos profissionais de tecnologia da informação na Organização, na Área e no ciclo de desenvolvimento de sistemas; busca analisar os ativos intangíveis representados pelo capital estrutural, de relacionamento e intelectual e o modelos de terceirização utilizados na Secretaria da Fazenda, Órgão integrante da Administração Pública Direta do Estado da Bahia, para a contratação de desenvolvimento e manutenção de sistemas em tecnologia da informação. O trabalho está fundamentado por um quadro teórico, baseado nos conceitos sobre gestão do conhecimento e seus ativos intangíveis, sobre a terceirização, os modelos e restrições legais no âmbito público e o contexto organizacional da tecnologia da informação, tendo como foco o desenvolvimento de sistemas. Foi realizada uma pesquisa de campo aplicada, na qual se abordou o problema como um estudo de caso exploratório e de cunho quali-quantitativo, privilegiando um entendimento analítico e suportado por observação, pesquisa documental e entrevistas efetuadas com o superintendente, diretor, gerentes, líderes de sistemas e gestores de sistemas da Secretaria da Fazenda do Estado da Bahia (SEFAZ-BA). O instrumento de pesquisa utilizado baseia-se em Rossatto (2003), que propõe três constructos: capital estrutural, capital de relacionamento e capital intelectual. Foram aplicados questionários seguindo o enquadre desses constructos e as respostas foram categorizadas e analisadas. Os resultados encontrados indicam a necessidade de uma efetiva gestão dos ativos intangíveis, apresentam os efeitos gerados pela terceirização nas fases do ciclo de desenvolvimento de sistemas e como o modelo de terceirização atual tem contribuído para o escape do conhecimento da Instituição e entrega de serviços em desacordo com o prazo e qualidade. Traz também contribuições de melhoria tendo em perspectiva o ambiente de desenvolvimento de sistemas e o processo “fim a fim” de gestão das demandas em tecnologia da informação. / Salvador

Requirements Engineering (RE) plays a vital role in Information Systems (IS) development. The collaboration of requirements engineers is at the core of RE activities and is typically supported by technology tools, with Jira being an example of such a tool. Since these technology tools, like Jira, are focused on the execution of traditional duties, the collaboration functionalities of these technology tools are unseen. Moreover, little research has been carried out to explore how requirements engineers’ collaboration is supported and the challenges are created by the technology tools. Interpretive qualitative research was conducted to understand the nature of requirements engineers’ collaboration in three IS development organisations in Sweden to better support it with technology tools. The empirical material was collected through semi-structured interviews and observations and was analysed thematically to generate seven themes.  The findings revealed that the technology tools facilitate requirements engineers’ cooperation, communication among multiple collaborating parties in one platform, coordination of work activities and information sharing among other collaborating parties. Additionally, it discovered that the inability to support real-time communication, high configurability, limited sharing possibilities, compatibility, technicality and complexity challenge and interrupt the requirement engineers’ collaboration.  Moreover, the theoretical frame findings are discussed with the help of the theoretical framework, including the activity theory. Requirements engineers’ collaboration is presented as a purposeful interaction among them and other people with the support of technology tools to complete the process of RE in information systems development. Their interactions and the importance of the technology tools are underlined. Hence, the outcome of the master’s thesis research shows that the collaborative technology tools enable the requirement engineers’ collaboration through supporting and facilitating their effective communication, cooperation, coordination, information sharing, and through facilitating their awareness, allowing them in this way to drive the information systems projects and/or products development into successful completion. The extended collaboration model presented in this research in combination with activity theory is used to understand the transformation of the enabling collaboration of requirements engineers.

A Phenomenological Analysis of Emergent Design is performed based on the foundations of General Schemas Theory. The concept of Sign Engineering is explored in terms of Hermeneutics, Dialectics, and Ontology in order to define Emergent Systems and Meta-systems Engineering based on the concept of Meta-dialectics. Phenomenology, Ontology, Hermeneutics, and Dialectics will dominate our inquiry into the nature of the Emergent Design of the System and its inverse dual, the Meta-system. This is an speculative dissertation that attempts to produce a philosophical, mathematical, and theoretical view of the nature of Systems Engineering Design. Emergent System Design, i.e., the design of yet unheard of and/or hitherto non-existent Systems and Meta-systems is the focus. This study is a frontal assault on the hard problem of explaining how Engineering produces new things, rather than a repetition or reordering of concepts that already exist. In this work the philosophies of E. Husserl, A. Gurwitsch, M. Heidegger, J. Derrida, G. Deleuze, A. Badiou, G. Hegel, I. Kant and other Continental Philosophers are brought to bear on different aspects of how new technological systems come into existence through the midwifery of Systems Engineering. Sign Engineering is singled out as the most important aspect of Systems Engineering. We will build on the work of Pieter Wisse and extend his theory of Sign Engineering to define Meta-dialectics in the form of Quadralectics and then Pentalectics . Along the way the various ontological levels of Being are explored in conjunction with the discovery that the Quadralectic is related to the possibility of design primarily at the Third Meta-level of Being, called Hyper Being. Design Process is dependent upon the emergent possibilities that appear in Hyper Being. Hyper Being, termed by Heidegger as Being (Being crossed-out) and termed by Derrida as Differance, also appears as the widest space within the Design Field at the third meta-level of Being and therefore provides the most leverage that is needed to produce emergent effects. Hyper Being is where possibilities appear within our worldview. Possibility is necessary for emergent events to occur. Hyper Being possibilities are extended by Wild Being propensities to allow the embodiment of new things. We discuss how this philosophical background relates to meta-methods such as the Gurevich Abstract State Machine and the Wisse Metapattern methods, as well as real-time architectural design methods as described in the Integral Software Engineering Methodology . One aim of this research is to find the foundation for extending the ISEM methodology to become a general purpose Systems Design Methodology. Our purpose is also to bring these philosophical considerations into the practical realm by examining P. Bourdieu?s ideas on the relationship between theoretical and practical reason and M. de Certeau?s ideas on practice. The relationship between design and implementation is seen in terms of the Set/Mass conceptual opposition. General Schemas Theory is used as a way of critiquing the dependence of Set based mathematics as a basis for Design. The dissertation delineates a new foundation for Systems Engineering as Emergent Engineering based on General Schemas Theory, and provides an advanced theory of Design based on the understanding of the meta-levels of Being, particularly focusing upon the relationship between Hyper Being and Wild Being in the context of Pure and Process Being.

<p>This dissertation examines the impact of active shooters upon patrons attending large outdoor events. There has been a spike in shooters targeting densely populated spaces in recent years, to include open-air venues. The 2019 Gilroy Garlic Festival was selected for modeling replication using AnyLogic software to test various experiments designed to reduce casualties in the event of an active shooter situation. Through achievement of validation to produce identical outcomes of the real-world Gilroy Garlic Festival shooting, the researcher established a reliable foundational model for experimental purposes. This active shooter research project identifies the need for rapid response efforts to neutralize the shooter(s) as quickly as possible to minimize casualties. Key findings include the importance of armed officers patrolling event grounds to reduce response time, the need for adequate exits during emergency evacuations, incorporation of modern technology to identify the shooter’s location, and applicability of a 1:548 police to patron ratio.</p>
