D.Ing. (Engineering Management) / Promotion of ICT usage in developing countries, even under rigorous government initia- tives and policies, is a discouraging undertaking and a very di cult one. One of the many challenges government of developing countries is facing in the promotion of ICT adoption is how to incorporate a subsidy rate discount into a price model as expressed in the following sentiments: Until now, USAASA has used very little of the money in the USAF. It must justify its spending plans each year before it is given access to any of Information on how price a ects the number of users was generated by asking users on how much the spent on internet usage. The sensitivity of users was determined by asking users how many hours they spent on the internet. Analysis of the information gathered showed that there was a substantial amount of money in USAASA and ZICTA co ers which was not utilized. Furthermore users expressed desire to have their prices subsidized. In rural areas internet prices were more expensive, on comparative terms, than those in the urban areas. Analysis of data or results concerning the price and the number of users showed that there was a positive relationship between the number of users and the price of the internet service. The relationship showed that a low price attracted a lot of users, while a high price attracted few users or none at all. The mathematical analysis of the pricing model proved that at a certain subsidy discount rate and price sensitivity, the model was able to reach equilibrium while maximizing the ISP's revenue. In conclusion the price of internet services for the information \have nots" depend on the price sensitivity and the level of subsidy given by the government. the funds". \Universal access of ICT services with particular reference to rural areas is an issue that has been on the agenda of most countries in the whole world today. You are aware that while some countries are currently e ectively extending services to rural areas using various means, others have found this challenging and have ended up with unutilized funds in the banks". Subsidies, though seen as the means of promoting social and economic agendas in developing countries, can create the tragedies associated with public resources usage or something-for-nothing resources. Given a subsidy discount rate or a low price, consumers usually anticipate a net bene t derived from free resources due to subsidy. Anticipation of net a bene t from such resources may generate a damaging rush from consumers to exploit the resource, which may result in the tragedy of the commons. On the contrary, when no subsidy is given, consumers face no di erential between the perceived utility and the price of the resource creating a no social and pecuniary bene t to users, as such very few consumers or users will utilize the resource. The contribution this research develops is as follows: To show the extent of ICT usage patterns in developing countries.To determine why ICT usage in developing countries is low even under rigorous government initiatives and policies. To determine how price a ects the number of users using the internet resource. To incorporate a subsidy discount rate in a price model for unserved or rural areas of developing countries. To proposes a subsidy driven pricing framework that helps both the internet service providers and users to maximize their utilities and prevent the tragedies associated with resource use i.e. the tragedy of the commons and the tragedy of the anti- commons. To apply a non-cooperative game theoretic model to investigate the con ict between ISPs and consumers or consumers in a heterogeneous communities i.e. the infor- mation \haves" and \have-nots". We de ne utility-based decision rules for both providers and users under varying prices and subsidy requirements. We provide a decision model under a non-cooperative, incomplete-information game environment. To investigates the properties of the NE (under di erent optimization rules) and to study whether there exists an optimal solution to the game. The basic hypothesis that this research addresses is: A pricing model, with correct subsidy discount rate allows for better resource usage (preventing the tragedy of the commons and anti-commons) and makes the attainment of the objective of \ICT access for all" more likely. The methodology used for collecting statistical data was a combination of qualitative and quantitative research methods. The purpose of research was to collect data that would later be used to propose a pricing framework for heterogeneous communities. The strategy was to use three important variables in the subsidy driven pricing model to validate the hypothesis i.e. subsidy discount rate, the relationship between price and the number of users and the sensitivity (elasticity of demand) of users towards price. Incorporation of subsidy discount rate into the pricing model was driven by the fact that institutional frameworks such as universal service and access agency of South Africa (USAASA) and the Zambia information and communications tech- nology authority (ZICTA) were sitting with unutilized universal service and access fund (USAF). Additionally, users of internet services in underserviced areas of the two countries advocated for subsidized prices towards internet provision.

Thesis (MTech (Information Technology))--Peninsula Technikon, 2005 / "This study was initiated to determine whether cost estimation is a necessary skill for an Information Technology (IT) consultant. The historic poor record in the software industry for delivering software projects within budget has highlighted a need for IT students to receive adequate preparation for future experiences in the world of work especially if they were to become self-employed. The literature revealed that a variety of employability skills are required when preparing students for entrepreneurship. In IT there is a particular need for project management skills when the entrepreneur is responsible for all aspects of the software project. Cost estimation is a key function of project management.

Thesis (MTech (Business Administration))--Cape Peninsula University of Technology, 2016. / The study, using a selected University of Technology (UoT) as a case study, investigated factors influencing information technology (IT) investments in adopting new technologies in University of Technologies (UoTs). The objective is to determine the benefits of IT investments in UoTs and the impact on UoT operations. Technology is constantly advancing and impacting on organisations’ decisions and how to acquire the right technology for effective administration. IT-investment decisions require unique understanding and management by organisations to properly adapt to changing technology. The research was based on the premise that the purpose of deploying new technologies in any organisation is to reduce the costs of running the organisation and to improve operational effectiveness. This would include Higher Education Institutions (HEIs). However, at most UoTs there is a slow response to adopting new technologies, making them lag behind in the deployment of such technologies.

Since 2005, most midsize company information technology (IT) projects had a 62.4% failure rate because of wrong project team communication skills or cost overruns. IT leaders expect negative IT project outcomes will cost over $2 billion by 2020. Using the actor-network theory, the purpose of this single case study was to explore strategies used by IT leaders from a midsize IT company in Washington, D.C. to plan and execute projects under budget and on time. Using purposeful sampling, 5 IT leaders were selected for this study because of their experience in implementing successful strategies for projects. Data were collected using face-to-face semistructured interviews, company documentation, and internal organizational risk reports. Yin's 5-step process was used for data analysis to compile, disassemble, reassemble, interpret, and conclude the data. The interpretation of data, subjected to methodological triangulation and member checking to strengthen the dependability and credibility of the findings, yielded 3 themes of IT leader communication skills: IT leader strategy, IT leader knowledge, and implementation of cost savings. The findings indicated that IT leaders serve as the key actors in the IT project network, and leader communication skills are essential for implementing strategies for IT project completion and cost savings. With this knowledge, IT leaders can implement strategies to plan and execute projects under budget and on time. The implications for a positive social change includes the potential for IT leaders to reduce project production waste and contribute to economic expansion.

Thesis (MPhil)--Stellenbosch University, 2005. / ENGLISH ABSTRACT: This paper discusses factors that contribute to information technology (IT) investment not paying off as might have been expected. The main purpose is to describe this IT _productivity paradox. The paper explores ideas that align organizations' business strategies and information technology as a key to achieving improved productivity. Which are possible to properly measure in terms of the financial results? The main aims and objectives are to find out why managers invest in IT; whether there is a phenomenon such as an IT productivity paradox; whether IT pays off as expected; and how IT impacts on organizations. The study will investigate options for proper management of information technology and data structures. It is necessary to ascertain whether ensuring proper IT implementation has a positive impact on productivity, leading to increased innovation and performance. The research design builds on research done on the use of IT in organizations, usmg a qualitative research method. This research paper looks at organizational issues such as IT management styles, political and ethical issues, and work settings. The paper looks at organizations across the service and manufacturing sectors to determine their production, innovation, and profits into their existing organizational processes and how technology is interpreted. A group of IT users, IT managers and analysts were used as a sample to study the way IT managers and knowledge workers encounter information technology in organizations. The research method used in this research paper is called the informant approach, to take points of entry IT users would provide. This means that the interviewee, in this case the IT user was questioned on the use of information technology tools to gather information. In this study the aim was to conduct interviews with IT users and those they work with about their experiences. The sampling population was selected on the basis that they use this technology. In the data collection method a second interview was used to gather first-hand responses from the respondents to help me consolidate the information gathered to validate and ensure that it is reliable. The validity and reliability aspect of this research paper are based on the main sources of data and interpretation and adopts coding as the main technique of analysis. The internal reliability of this research methodology concern itself with the research methods that were used within this research paper. Measures to be taken in the paper are to obtain internal reliability in systematic gathering of data. The last part of this paper presents the conclusions and recommendations for changes to be made by managers and those investing in IT. IT managers should plan strategically when dealing with sales and marketers in order to put business needs before the needs of IT or systems. Technology should fit business needs rather than the business adjusted to fit the technology. IT should not cost an organization any additional profit it generates. / AFRIKAANSE OPSOMMING: Belegging in Informasietegnologie skyn nie so betalend te wees as wat aanvanklik verwag is nie. Hierdie studie beskryf bogenoemde IT produktiwiteitsparadoks, en ondersoek faktore wat daartoe bydra. Verder word planne wat ten doel stel om organisasies se besigheidsstrategie en IT te laat saamwerk ten einde produktiwiteit te verhoog, ondersoek. Is dit moontlik om hierdie te meet in terme van finansiële resultate? Ander voornemens is om te bepaal waarom bestuurders in IT belê, is dit so betalend soos aanvanklik geskat is, hoe dit die maatskappy beïnvloed en bestaan daar werklik 'n verskynsel soos die IT produktiwiteitsparadoks? Hierdie studie sal moontlikhede ondersoek vir kundige bestuur van IT en datastrukture. Dit is nodig om vas te stel of die deeglike toepassing van IT 'n positiewe uitwerking het op vernuwende denke en produktiwiteit. Die navorsingsontwerp is gebaseer op navorsing wat reeds gedoen is oor die gebruik van IT in organisasies. In hierdie navorsing word ondersoek ingestel na organisatoriese kwessies soos IT bestuursmetodes, politieke en etiese invloede en werksomstandighede. Hierdie dokument neem maatskappye regoor die diens- en vervaardingsektore in oënskou ten opsigte van hul produksie, vernuwende idees en winsmarge, hoe hierdie aspekte inpas in hul huidige organisatoriese prosesse en hoe tegnologie interpreteer word. 'n Groep van IT gebruikers, IT bestuurders en analiste is as monster geneem, ten einde die manier waarop IT bestuurders en inligtingwerkers informasietegnologie teëkom in maatskappye te bestudeer. Die navorsingsmetode wat tydens hierdie studie gebruik is, word genoem die informantbenadering, wat behels om informasie te gebruik wat deur IT gebruikers verskaf word. Dit beteken dat die IT gebruiker ondervra word oor die gebruik van IT toerusting om informasie te versamel. Die doelwit was om onderhoude met IT gebruikers te voer, asook diegene met wie hulle saamwerk, in verband met hulondervindinge. Die steekproefpopulasie is gekies op grond daarvan dat hulle IT gebruik. In die datainsamelingsmetode is 'n tweede onderhoud gehou om eerstehandse menings van die respondente te verkry, met die doel om die informasie tot dusver te bevestig as betroubaar. Die geldigheid- en betroubaarheidsaspekte van hierdie dokument is gebaseer op die hoofbronne van data en vertolking en gebruik kodering as die primêre tegniek van analise. Die intrinsieke betroubaarheid van hierdie navorsingsmetode is gebaseer op die navorsingsmetodes wat gebruik is vir hierdie studie. Stappe is geneem tydens die studie om intrinsieke betroubaarheid te verkry deur die sistematiese verkryging van data. Die laaste deel van hierdie dokument bied die gevoltrekkings aan en ook voorstelle vir veranderings wat gemaak kan word deur bestuurders en diegene wat belê in IT. IT bestuurders behoort strategies te beplan wanneer hulle in aanraking kom met handelaars, om doelgerig die benodighede van die maatskappy te stel voor die benodigdhede van die IT en gepaardgaande sisteme. Tegnologie behoort in te pas by die benodigdhede van die maatskappyeerder dat die maatskappy hoef aan te pas by die tegnologie. IT behoort nie die maatskappy meer uit die sak te jaag as wat dit aan wins genereer nie.
