The right to information privacy is considered a basic human right in countries that recognise the right to privacy. South Africa, and other countries that recognise this right, offer individuals legal protections for their information privacy. Individuals, organisations and even governments in these countries often have an obligation under such laws to protect information privacy. Large organisations, for example, multinational companies and government departments are of special concern when it comes to protecting information privacy as they often hold substantial amounts of information about many individuals. The protection of information privacy, therefore, has become ever more significant as technological advances enable information privacy to be breached with increasing ease. There is, however, little research on holistic approaches to protecting information privacy in large organisations. Holistic approaches take account of both technical and non-technical factors that affect information privacy. Nontechnical factors may include the management of information privacy protection measures and other factors such as manual business processes and organisational policies. Amongst the protections that can be used by large organisations to protect information privacy is the ability to investigate incidents involving information privacy. Since large organisations typically make extensive use of information technology to store or process information, such investigations are likely to involve digital forensics. Digital forensic investigations require a certain amount of preparedness or readiness for investigations to be executed in an optimal fashion. The available literature on digital forensics and digital forensic readiness (DFR), unfortunately, does not specifically deal with the protection of information privacy, which has requirements over and above typical digital forensic investigations that are more concerned with information security breaches. The aim of this thesis, therefore, is to address the lack of research into DFR with regard to information privacy incidents. It adopts a holistic approach to DFR since many of the necessary measures are non-technical. There is, thus, an increased focus on management as opposed to specific technical issues. In addressing the lack of research into information privacy-specific DFR, the thesis provides large organisations with knowledge to better conduct digital forensic investigations into information privacy incidents. Hence, it allows for increased information privacy protection in large organisations because investigations may reveal the causes of information privacy breaches. Such breaches may then be prevented in future. The ability to conduct effective investigations also has a deterrent effect that may dissuade attempts at breaching information privacy. This thesis addresses the lack of research into information privacy-specific DFR by presenting a framework that allows large organisations to develop a digital forensic readiness capability for information privacy incidents. The framework is an idealistic representation of measures that can be taken to develop such a capability. In reality, large organisations operate within cost constraints. We therefore also contribute by showing how a cost management methodology known as time-driven activity-based costing can be used to determine the cost of DFR measures. Organisations are then able to make cost versus risk decisions when deciding which measures in the framework they wish to implement. Lastly, we introduce the concept of a digital forensics management system. The management of DFR in a large organisation can be a difficult task prone to error as it involves coordinating resources across multiple departments and organisational functions. The concept of the digital forensics management system proposed here allows management to better manage DFR by providing a central system from which information is available and control is possible. We develop an architecture for such a system and validate the architecture through a proof-of-concept prototype. / Thesis (PhD)--University of Pretoria, 2012. / Computer Science / unrestricted

隨著資訊科技與生產技術大幅進步，以及全球化及自由化下瞬息多變的競爭環境，經營者除了關注企業內部的議題外，亦需了解全球經濟發展趨勢與產業脈動，在競爭者與客戶回應之前，提出有效對策因應，如此才能在激烈的競爭中存續與發展，維持競爭力及提升經營績效。因此，現今企業勝出的核心關鍵不再單純依賴規模與效率，而是如何發揮創意，找出新的競爭定位，並藉助資訊快速運算及不斷增強的商業智慧功能來改善企業本身的經營條件，甚或尋求新的商業模式。 個案公司是一家電子零組件製造與銷售公司，主要產銷連接器、軟性排線及線材組件。和大多數公司一樣，個案公司目前正面臨全球化競爭帶來的挑戰。處於原物料及人力成本持續上漲的壓力，以及面對客戶少量多樣客製化的產品需求與愈趨繁複的出貨要求下，個案公司之產品毛利愈來愈低。為解決這些經營上的問題，個案公司期待運用ERP資訊系統客製「商品計價作業」來反映成本上漲對產品報價的變動，並藉此快速且適度反應到對客戶的報價上，以期提升經營彈性，因應市場變化。 本研究從個案公司為了因應市場變化而建置資訊系統，以期快速且正確的反映產品報價的需求出發，首先針對個案公司，應用企業流程資訊有機體(Process-Wide Information Organism, PWIO)分析模式，重現及檢視個案公司銷售流程，並結合時間導向的作業基礎成本制求算出客戶最終毛利，據此重分類客戶屬性，並提出對應之銷售策略及對資訊系統需求之反思與建議。 關鍵字：企業流程資訊分析模式、顧客利潤分析、時間導向作業基礎成本制度 / Information technology and manufacturing techniques are greatly improved by days. The globalization and liberalization make industrial competition fierce and ever-changing. Under such circumstances, the company managements can not only focus on internal topics but should observe the global economic development trend and also the commercial and industrial variety. They should put forward solution strategies to deal with the responses of competitors and requests of customers. Only then can they keep competition power and enhance the operation profit to continue sustainable operation and development in the sharp competition. Therefore the key success factor today is not to depend on operation scale and efficiency only but to bring creativeness into full play to find the competition advantage of the company. In addition, they should improve management conditions by means of rapid information operation and ever-growing business intelligent features or to create new business model. A case company is a component manufacturing and sales company. Its main products are connectors, flexible flat cable and wire harness. Facing the severe global competition as the others, the company is challenged by margin issue due to increasing cost of raw material and labor, customized products requests with high-mix/ low-volume. To conquer this business issue, the case company plans to utilize ERP to build up the “Product Pricing Program” to re engineer the pricing methodology by reflecting the increased cost in the quotations to customers. The pricing process can enhance the operation efficiency to respond to the variety market changes. To deal with the market changes, the case study is aimed to establish effective information system for the purpose of responding rapidly and precisely to pricing decision. The research reviews and inspects the sales flow of the case company by Process-Wide Information Organism (PWIO). It also combines the time-oriented activity base costing (ABC) to forecast the final gross profit of customers. Based on this, the case company could re-categorize the customer segmentation and put forward related sales strategy and enhancement on the demand of information system. Key words: Process-Wide Information Organism (PWIO); Customer profitability analysis; Time-Driven Activity-Based Costing

Abstracts in English, Xhosa and Afrikaans / The South African Social Security Agency (SASSA) is the mechanism that enables service delivery to alleviate poverty in South Africa through the payment of social grants as mandated by the Social Security Agency Act No. 9 of 2004. The rapid increase of social grant beneficiaries in the past decade, fuelled by social inequality, directly affects the administration cost associated with social grants. This study aimed to investigate the allocation of indirect costs related to the administrative elements that makes it possible for SASSA to pay social grants. Semi-structured interviews were conducted; the study concluded that ABC (activity-based costing) could be implemented as an alternative to the traditional costing (TC) method on a pilot project basis. The study also recommended a framework for SASSA to consider in laying the foundation to start the process of ABC implementation. Drawing from the research conducted, further studies on the implementation of ABC principles within the public sector could be pursued. / Ejensi ya Vuhlayiseki bya Vanhu ya Afrika Dzonga ku nga South African Social Security Agency (SASSA) i ndlela leyi endlaka leswaku mphakelo wa vukorhokeri wu koteka ku hunguta vusweti eAfrika Dzonga hikwalaho ka ku hakeriwa ka timalimpfuneto ta vanhu (social grants) tanihileswi swi pfumeleriweke hi Nawu wa Social Security Agency Act 9 wa 2004.

Die aansienlike toename in die aantal begunstigdes het ʼn uitwerking op die administrasiekoste van sosiale toelaes. Hierdie studie ondersoek die toewysing van indirekte koste ten opsigte van die administratiewe elemente wat SASSA in staat stel om sosiale toelaes te betaal. Halfgestruktureerde onderhoude is gevoer. In hierdie studie word tot die gevolgtrekking gekom dat aktiwiteitsgebaseerde kosteberekening (ABK) as ʼn alternatief vir en as ʼn proefprojek die tradisionele kosteberamingsmetode geïmplementeer kan word. ʼn Raamwerk word aanbeveel wat as ʼn grondslag kan dien vir die implementering van ABK. / College of Accounting Sciences / M.
