M. Tech. Business Information Systems / Technology has become essential to the running of many enterprises in the modern world as it can enable businesses and help them operate more efficiently and effectively. Information Systems are developed to help in the daily running of business operations. Information systems projects are undertaken to manage the delivery of these Information Systems and enable the business through technology solutions. However, not all projects succeed in delivering their required solution and benefits. This dissertation is about understanding how Information Systems projects are managed and how that could be improved. The study, underpinned by the Work System Theory, explored Information Systems project management; it reveals how Information Systems projects are managed and the factors influencing project failure or success. This goal of this research was to conceptualise a framework for improving the management of Information Systems projects.

M. Tech. Business Information Systems / Information Technology projects can fail for any number of reasons and in some cases can result in considerable financial losses for the organisations that undertake them. One pattern of failure that has been observed but seldom studied is the IT project that seems to take on a life of its own, continuing to absorb valuable resources without reaching its objective. The research study investigated the different challenges and failures of IT projects and looked at the root causes of these failures and how to overcome them. This research study was informed by the use of a case study of Liberty Life, one of the largest financial service providers in South Africa. The primary research question that informs this research study is: How mature is the organisation in implementing Information Technology projects.

Thesis (MPhil)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: Development, a non-ceasing phenomenon as long as mankind has dwelt on this planet, IS a complex matter which encompasses the three bottom-lines, i.e. social, economic and environmental aspects and aims at improving the quality of life. In fact, development issues are always challenging countries and their leaders as they try to introduce strategies and projects to benefit their rural sector which constitutes, especially in developing countries, most of the population who are living in poverty and continuing to stagger in very destitute level. One of these countries is Eritrea, a nation of which more than 80% live in rural areas and which is rated one of the lowest twenty nations on the human development index (measurement of literacy, health and life expectancy status) as well as the human poverty index of which 53% of the population lived below national poverty line during the period of 1987 to 2000 (UNDP, 2002). This paper is an attempt to discuss rural development and how it is being implemented in relation to Eritrea's reconstructions and rehabilitation efforts that took place after its freedom from foreign occupation. It is an assessment on the rural projects' planning and implementation process, and eventually also looks at the impacts they have on the life of the beneficiaries. As a whole, this research paper consists of an introduction and nine chapters. It can be classified into five parts, i.e. the theoretical literature, the country's status in specific fields, the sample research areas, an overall synthesis and lastly conclusions and recommendations as one part. The theoretical background revolves around rural areas and their reasons for poverty, different development theories within which rural development could be seen as one ingredient, and focuses on participatory rural development where projects can play vital roles in changing life style especially when they are managed in an integrated way touching main areas of need. The second section of the paper is a general overview of the socio-economic status of Eritrea and some of the efforts made by the government. These are mainly the health, education, water supply, agriculture and darn construction projects, accomplished mainly by government in partnership with domestic and foreign NGOs, whereas the same time people contributed mainly in kind. In relation to these five projects the researcher has drawn up questionnaires and personally filled them in five villages, namely Sheeb, Ade-awhi, Korbariaya, Azien and Wara, while at the same time holding discussions with the beneficiaries. In this section the assessment of the people's state and their response in relation to the planning process as well as impacts of the projects on their lives have been made for every village. In other words, the chapter shows the practical data analysis of the research. The next is, in similar form, an overall synthesis of the research. The researcher weighs and analyses the results in relation to planning issues, especially how far the people played a role in participation and the extent of their influence as well as their contentment with the end result in comparison to their expectations. Moreover, it investigates the projects' impact on the environment, and their influence on the socio-economic lives of the beneficiaries, and then sees how the projects have been managed at institutional level and whether the policies that are in effect have direct influence on initiating rural development projects. Finally some conclusions are drawn and recommendations are made that could be a benchmark for further studies and provide impetus to accelerate the present rural development planning and implementation. The researcher may have overlooked some necessary elements or missed some basic factors in dealing the current way of initiating development. But with the resources were available and the time at his disposal, while faced by the limitations explained in the introductory section of the paper, the researcher has made some efforts to highlight his convictions to the best of his academic ability. The sole purpose of his final statements is based on his wish for more rural upliftment and long-term as well as sustainable benefit to the rural people of his country, Eritrea. / AFRIKAANSE OPSOMMING: Ontwikkeling, 'n verskynsel wat nie ophou nie, bestaan al so lank as wat daar lewe op die planeet bestaan. Dit is 'n ingewikkelde saak wat drie aspekte behels: die sosiale, ekonomiese en omgewings aspekte en die doel daarvan is om lewensgehalte te verbeter. Ontwikkelingskwessies stel 'n uitdaging aan die leiers van lande; die regerings moet stategië uitwerk en projekte van stapel stuur wat die landelike sektor sal bevoordeel en veral in ontwikkelende lande, woon die grootste gedeelte van die bevolking op die platteland waar hulle gebuk gaan onder armoede. Eritrea is een van hierdie lande. 80% van die mense van Eritrea woon op die platteland. Etritrea word gereken as een van die twintig onontwikkelste lande op die menslike ontwikkelings indeks (wat geletterdheid, gesondheid en lewensverwagting meet) en ook op die menslike armoede indeks. 53% van die bevolking het vir die tydperk 1987 tot 2000 onder die nasionale armoedelyn geleef (UNDP, 2002). In hierdie studie word landelike ontwikkeling bespreek en hoe dit geïmplementeer is tydens die rekonstruksie en rehabilitasie pogings na die onafhanklikheid van Eritrea. Dit is 'n waardebepaling van die beplanning en implementasie van die landelike projekte en kyk ook na die impak wat dit op die lewens van die landelike bevolking gehad het. In die geheel bestaan hierdie studie uit 'n inleiding en nege hoofstukke. Dit kan in vyf afdelings ingedeel word: teoretiese literatuur, die stand van die land betreffende spesifieke gebiede, die navorsingsgebiede, 'n oorsigtelike sintese en ten laaste die gevolgtrekkings en aanbevelings. In die teoretiese agtergrond gaan dit om die landelike gebiede en die redes vir armoede, asook die ontwikkelingsteorië waarin landelike ontwikkeling gesien word as een bestandeel. Dit fokus op deelnemende landelike ontwikkeling waarin projekte 'n belangrike rol kan speel om die lewensgehalte te verbeter, veral as dit bestuur word op 'n geïntegreerde wyse en die grootste behoeftes aanspreek. Die tweede afdeling is 'n algemene oorsig van die sosio-ekonomiese stand van Eritrea en van die regering se pogings om dit te verbeter. Die vyf projekte wat betudeer is, is gemoeid met gesondheid, onderwys, water voorsiening, landbou en die konstruksie van damme. Die regering het hierdie projekte onderneem in vennootskap met plaaslike en buitelandse nie-regerings organisasies (NGOs) maar die bevolking self het ook 'n bydrae gemaak, gewoonlik in die vorm van arbeid. Met betrekking tot hierdie vyf projekte het die navorser vraelyste opgestel en dit persoonlik in die vyf dorpies naamlik Sheeb, Ade-awhi, Korbariaya, Azien en Wara voltooi terwyl hy dan ook besprekings met die bevolking gehou het. In hierdie afdeling word daar vir elke dorpie'n waardebepaling gedoen van die toestand van die mense en hulle reaksie op die beplanningsproses asook die impak van die projek op hulle lewe. Dan volg 'n oorsigtelike sintese van die navorsing. Die navorser weeg die resultate op en analiseer dit veral betreffende beplanning en tot hoe verre die mense self 'n rol gespeel het, hoeveel invloed hulle gehad het en of die resultaat aan hulle verwagtings voldoen. Die studie kyk ook na die impak van die projek op die omgewing en die invloed wat dit gehad het op die sosio-ekonomiese lewens van diegene wat veronderstel is om voordeel daaruit te trek. Daar word gekyk na hoe die projekte op hoër vlak bestuur is en of regeringsbeleid 'n invloed het op die beplanning van landelike ontwikkelingsprojekte. Dan word gevolgtrekkings en aanbeveling gemaak wat tot nut kan wees vir ander navorsers en kan lei tot beter en vinniger beplanning en implementasie van landelike ontwikkelings projekte. Die navorser het dalk per abuis sekere elemente en basiese faktore oorgesien maar met die hulpbronne en tyd tot sy beskikking asook die beperkings wat in die inleiding tot die studie bespreek word, het hy sy oortuigings op skrif gestel tot die beste van sy vermoë. Hy hoop dat sy aanbevelings sal lei tot groter landelike ontwikkeling op die lang termyn en dat die mense van sy land, Eritrea, die volgehoue voordeel sal trek.

ENGLISH ABSTRACT: Most people working in the software industry recognise that developing software to predictable schedules is risky and not easy. They experience problems to estimate how long the development of software will take. Underestimation leads to under staffing and setting too short a schedule. That in turn leads to staff burnout, low quality and missed deadlines. Overestimation can be almost as bad: Parkinson's Law that work expands to fill available time comes into action, which means the project will take as long as estimated even if overestimated. Currently people do no put in much effort to estimate jobs and therefore projects take as long as they take. Methods to manage uncertainty lead to putting in excessive safety and then wasting it. Business usually presents a target for the project with tremendous pressure for low 'estimates' during the bidding process and in the end this target becomes the plan. Best practice appears to manage the gap between this target and the estimate as a risk on the project. Without an efficient work breakdown structure (WBS) one cannot accurately estimate. Subject experts should help the project manager to plan the detail of how the work should be done. A functional design by a systems architect helps to break down the technical tasks. This is very important because omitted tasks will not be estimated for. The first step towards sound estimates is to estimate the size. This is extremely difficult at the initial phase but can be overcome if the company store history of size and completion time in a repository. Although lines of code are most often used as a size measure, function points or function blocks appear to be better, especially for the initial estimate. If an organisation has not kept historic data, now is the time to start doing it. The suggested procedure to follow before starting to gather information, is to define what is going to be kept (the norms), to delimit the defined data, to discipline the collection, to deposit it in an established repository and to deliver it in readily usable format. The tool used for storing these metrics must provide building in factors that influence effort like complexity, skills level, elapsed time, staff turnover, etc. There are many different techniques for estimation. The best option seems to use a combination of estimates and include developer opinion and a mathematical method like function point analysis. Estimation of software development, like all other work processes, need management control and this is called metrics management. This process includes establishing some kind of modeL Empirical models, based on a database with data stored by ones own company, give the best results. Two very good models are the Putnam model and the Parr model (for smaller projects). Even the best model and process is never perfect. Therefore the estimation process must be continuously monitored by comparing actual duration times to estimates. Be careful with feedback on how accurate estimates were. No feedback is the worst response. Carefully discussing the implications of underestimation and putting heads together to solve the problem appears to be the best solution. / AFRIKAANSE OPSOMMING: Die meeste mense in die sagteware industrie erken dat om sagteware te ontwikkel teen voorspelbare tydskedules, gevaar inhou en nie maklik is nie. Hulle ondervind probleme om te skat hoe lank die ontwikkeling van sagteware hulle gaan neem. Onderskatting lei tot te min hulpbronne en te kort skedules. Dit veroorsaak uitbrand van mense, lae kwaliteit en einddatums wat nie gehaal word nie. Oorskatting is byna net so erg. Parkinson se Wet dat werk geskep word om beskikbare tyd te vul, kom in aksie en aan die einde beteken dit die projek neem so lank as wat geskat is, selfs al is dit oorskat. Huidiglik doen mense nie veel moeite om tyd te skat op take nie en daarom neem projekte so lank as wat dit neem om te voltooi. Metodes om onsekerheid te bestuur lei tot die byvoeg van oormatige veiligheidstyd net om dit daarna weer te verkwis. Die besigheid verskaf gewoonlik 'n mikpunt vir die projek met geweldige druk vir lae skattings tydens bieery en op die ou end raak hierdie mikpunt die projekplan. Die beste manier om dit die hoof te bied is om die gaping tussen hierdie mikpunt en die skatting te bestuur as 'n projek risiko. Niemand kan akkuraat skat sonder 'n effektiewe metode van werk afbreek nie. Vakkundiges behoort die projekbestuurder te help om die detail van hoe die werk gedoen gaan word, te beplan. 'n Funksionele ontwerp deur 'n stelselsargitek help om die tegniese take verder af te breek. Dit is baie belangrik aangesien take wat uitgelaat word, nie in die skatting ingesluit gaan word nie. Die eerste stap om by gesonde skattings uit te kom, is om grootte te skat. Dit is besonder moeilik in die aanvanklike fase, dog kan oorkom word indien die maatskappy geskiedenis stoor van hoe groot voltooide take was en hoe lank dit geneem het. Alhoewel Iyne kodering die mees algemeenste vorm van meting van grootte is, Iyk dit asof funksie punte of funksie blokke beter werk, veral by die aanvanklike skatting. Indien 'n organisasie nie historiese data stoor nie, is dit nou die tyd om daarmee te begin. Die voorgestelde prosedure om te volg voordat informasie gestoor word, is om te definieer wat gestoor gaan word (norme te bepaal), om die data af te baken, dissipline toe te pas by die insameling, dit te stoor in 'n gevestigde databasis en dit beskikbaar te stel in bruikbare formaat. Die instrument wat gebruik word om hierdie syfers te stoor moet voorsiening maak vir die inbou van faktore wat produksie beinvloed, soos kompleksiteit, vlak van vaardigheid, verstreke tyd, personeel omset, ens. Daar bestaan menige verskillende tegnieke vir skatting. Die beste opsie blyk 'n kombinasie van skattings te wees. Die opinie van die programmeur asook een wiskundige metode soos funksie punt analise, behoort deel te wees hiervan. Soos alle ander werksprosesse, moet skattings vir sagteware ontwikkeling ook bestuur word en dit word metrieke bestuur genoem. Hierdie proses behels dat daar besluit moet word op een of ander model. Empiriese modelle gebaseer op 'n databasis waarin data gestoor word deur die maatskappy self, gee die beste resultate. Twee baie goeie modelle is die Putnam model en die Parr model (vir kleiner projekte). Selfs die beste model en proses is egter nooit perfek nie. Die estimasie proses moet dus voortdurend gemonitor word deur werklike tye met geskatte tye te vergelyk. Wees versigtig met terugvoer aangaande hoe akkuraat skattings was. Geen terugvoer is die ergste oortreding. Die beste oplossing skyn te wees om die implikasie van die onderskatting met die persoon wat die skatting gedoen het, te bespreek en koppe bymekaar te sit om die probleem op te los.

Thesis (MBA (Business Management))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: Despite the growth and adoption of project management expertise and techniques, the increase in organisational project-maturity and the emergence of the Web, project success remains a challenge. A key factor leading to the continued failure in IT projects is the lack of identification and appreciation for the key factors that influence the success of project management success. Therefore the researcher embarked on this study to determine the top five critical success factors of project management in the South African ICT environment. The researcher also determined during which phases of the project life cycle these critical success factors occur. In order to determine these objectives, qualitative research was conducted that included a study of literature, available material, views from experts as well as a content analysis from sample interviews. South African ICT companies do not directly focus on any critical success factors, but indirectly they do focus on certain areas that will increase the probability of project management success. The research identified the top five critical success factors as a comprehensive project management plan, well defined scope, skilled and experienced project managers, user / customer involvement and top management support. The research also identified that the focusing on the project planning and project execution and monitoring phases of the project life cycle are the most crucial for project management success. In addition the research identified that project managers who have a strong technical background understand the complexities of the product better and do tend to manage the deferent component of the projects more effectively. / AFRIKAANSE OPSOMMING: Ten spyte van die groei en toename in projekbestuurkundigheid en -tegnieke, die toename in organisatoriese projek volwassenheid en die uitbreiding van die Web, bly projeksukses ‘n uitdaging. Om die rede het die navorser die studie onderneem om die vyf top kritiese suksesfaktore van projekbestuur in die Suid-Afrikaanse ICT omgewing te bepaal. Om hierdie doelwit te bepaal is kwalitatiewe navorsing onderneem wat ‘n literatuurstudie, beskikbare materiaal, opinies van kundiges sowel as inhoudsanalise van onderhoude gevoer insluit. Suid-Afrikaanse ICT maatskappye fokus nie direk op enige kritiese suksesfaktore nie, maar indirek fokus hulle wel op sekere areas wat die waarskynlikheid van projekbestuur sukses sal laat toeneem. Die navorsing identifiseer die vyf kritiese suksesfaktore as ‘n samevattende projekbestuursplan, goed gedefinieerde omvang, kundige en ervare projekbestuurders, gebruiker/kliënt betrokkenheid en topbestuur ondersteuning. Die navorsing het ook identifiseer dat die fokus op projekbestuursbeplanning, en projekuitvoering en monitering fases van die projeklewensiklus die mees kritiese is vir projeksukses. Die navorsing het ook identifiseer dat projekbestuurders wat ‘n sterk tegniese agtergrond het die ingewikkeldheid van die eindproduk beter verstaan asook die verskillende komponente van die projek meer effektief bestuur.

Thesis (MBA)--Stellenbosch University, 2002. / This thesis probes the range of factors affecting construction project delays through a literature review and survey of practical experience case studies. The focus is on engineering projects that were not completed in time. A total of eight articles have been studied and seven case studies surveyed. From the findings of this study it is noted that projects that do not complete in time could be categorised into three types namely Employer responsible (E), Contractor responsible (C) and Neither party responsible (N). The causes of delay identified from the literature study are superimposed on the causes identified from the case studies. Furthermore the causes of delay are classified in terms of importance, severity and frequency. It was established that causes resulting from design changes, ranked high in this classification whereas causes resulting from unprediotable weather conditions ranked low. Based on the literature review and the case studies, conclusions are drawn and finally recommendations are made.

Thesis (MBA)--Stellenbosch University, 2012. / This research investigates the volunteer tourism industry in Namibia, a niche market of the tourism industry. The tourism industry is the fastest growing sector in the economy (Travel News Namibia, 2012: 9), and it is also the second largest contributor to GDP (Ministry of Environment and Tourism Annual Report, 2010: 14). Although the volunteer tourism industry has been active for more than 20 years, it is currently having trouble with its status as a recognised sector of the tourism industry. Industry members mostly fear that investments to grow the industry are at risk due to uncertain entry visa requirements for international volunteers. There is also a concern that the industry is not regulated like other sectors of the tourism industry and that volunteer tourism is not recognised with equal status. Industry members feel ignored when it comes to national marketing campaigns and when representative bodies act in their interest. Industry members also expressed concern being left out when it comes to drafting new laws that affect the industry. To understand the industry, it is vital to analyse the industry from an internal and external perspective. This includes an analysis of the current status of the strategic architecture of the industry and an environmental analysis. The report also presents innovations to a typical strategic architecture model. Information and data for this research report was gathered from tourism industry stakeholders and experts, managers of five of the biggest industry players, and international volunteers. The findings of the investigation reveal that the business model of the industry is working well. Initiatives for continuous improvement, however, remain small due to uncertainties experienced in the macro-environment. The competitive environment of the industry is conducive to performance, as well as price and costing models. Demand for volunteering in Namibia is on the increase and the industry has realised that it needs to prepare itself to capture its full potential. The establishment of the Namibia VolunTourism Forum, which is represented through important stakeholders of the industry, is a first step to find solutions to the many challenges. This report serves as a working paper for the tourism industry and in particular for the volunteer tourism industry with the aim to increase stakeholder value.

Thesis (MScEng)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: Constructability issues cause dire repercussions in the industry and often pose as overwhelming threats to the successful delivery of projects. Constructability issues mainly arise from a design, which does not sufficiently embody the knowledge and expertise of the construction phase. Subsequently this creates a variety of negative secondary effects during project execution, which eventually manifest as time-, budget- and quality-risks to the project. The research thesis explores the status quo of constructability issues in South Africa, with specific reference to the relationship between construction and design. It is well known that close collaboration between consultants and contractors has the potential to lead to more effective construction processes, improved construction safety and to cost effective structural solutions. Not all contract forms allow sufficient collaboration between these parties at the time of conceptual design, nor at the detailed design stage. For this reason it is imperative that a designer has sufficient experience and knowledge of construction processes to produce suitably constructible designs. In principle, constructability issues can be regarded as the result of poor coherence, and thus poor communication, between construction and design. The problem therefore lies in the transfer of knowledge between project participants, which can be described as poor knowledge management, in particular, of constructability knowledge. This research aims to address the topic of constructability and to demonstrate how structural knowledge management between contractors and designers can lead to improved construction processes. The concept of constructability is defined, through the identification of technical traits to explicitly describe constructability, concurrently with input from industry expertise and professional experience in the field. Knowledge management principles are also studied in detail and the status quo of current knowledge management initiatives in the industry is investigated. The investigations are done through a series of questionnaire surveys, personal interviews and correspondences. The principle conclusions from the study are that designers do not always understand what constitutes a constructible design. Furthermore, although constructability knowledge is found to exist in complex tacit forms, some explicit guiding principles can indeed be formulated to aid designers. In addition, considering the unique characteristics of each project, these guiding principles should be supported by proposed knowledge management initiatives to facilitate structured forums of knowledge sharing between different parties to develop and transfer constructability knowledge. This will assist to accelerate the learning process towards becoming an accomplished designer, and empower the capacity of both designers and contractors to manage constructability problems. / AFRIKAANSE OPSOMMING: Boubaarheidsprobleme veroorsaak ernstige gevolge in die bedryf en hou dikwels oorweldigende bedreigings in vir die suksesvolle lewering van projekte. Boubaarheidsprobleme ontstaan hoofsaaklik as gevolg van „n ontwerp wat nie genoeg kennis van die konstruksiefase behels nie. Gevolglik, word „n verskeidenheid van negatiewe sekondêre effekte geskep tydens die projek uitvoering, wat risikos uiteindelik veroorsaak in aspekte van tyd, geld en kwaliteit. Heirdie navorsing ondersoek die status quo van boubaarhiedsprobleme in Suid Afrika, met spesifieke verwysing na die verhouding tussen konstruksie en ontwerp. Dit is bekend dat geskikte samewerking tussen konsultante en kontrakteurs kan lei tot meer effektiewe bouprosesse, verbeterde bouveiligheid en goedkoper strukturele oplossings. Kontraktuele ooreenkomste laat nie altyd toe vir behoorlike samewerking tussen die partye gedurende ontwerp stadiums nie. Om hierdie rede, is dit noodsaaklik dat „n ontwerper voldoende ervaring en kennis van die konstruksie prosesse bevat, om behoorlike boubare ontwerpe te kan poduseer. In beginsel, kan boubaarheidsprobleme beskou word as „n gevolg van swak kommunikasie tussen konstruksie en ontwerp. Die problem lê dus in die oordrag van kennis tussen projek deelnemers, wat ook beskryf kan word as swak kennis-bestuur, in die geval, van boubaarheidskennis. Hierdie navorsing beoog om die onderwerp van boubaarheid aan te spreek en te demonstreer hoe strukturele kennis-bestuur tussen die kontrakteurs en ontwerpers tot verbeterde konstruksie prosesse kan lei. Die konsep van boubaarheid word gedefinieer, deur die idenfisering van tegniese eienskappe wat boubaarheid eksplisiet kan beskryf, gelyktydig met die insette van industrie kundigheid en professionele ondervinding. Kennis-bestuur beginsels word ook in diepte bestudeer en die status quo van die huidige kennis-bestuur inisiatiewe in die bedryf word ondersoek. Die ondersoeke word gedoen deur middel van vraelys opnames, persoonlike onderhoude en korrespondensies. Die algemene gevolgtrekkings uit die studie is dat ontwerpers nie altyd die implikasies van „n boubare ontwerp verstaan nie. Verder, alhoewel boubaarheidskennis bestaan in komplekse vorms in die gedagtes van konstruksie personeel, eksplsiete riglyne kan wel geformuleer word om die ontwerp prosses to steun. Aangesien projekte uniek is, moet hierdie riglyne ondersteun word deur die voorestelde kennis-bestuur inisiatiewe, om oop platforms van kennis oordrag te fasiliteer tussen verskillende partye. Dit sal help om die leer prosess te versnel en sal die kapasiteit van beide ontwerpers en kontrakteurs bemagtig, sodat hulle boubaarheidsprobleme beter te kan hanteer.
