Item Exploring barriers to land accessibility for low-income housing delivery: A case of buffers of open space on the mining belt between Johannesburg CBD and Soweto(2007-02-22T12:39:55Z) Baloyi, Hlengani GoldwinThis is an exploratory study which seeks to look at barriers to land accessibility for the construction of low-income or affordable housing on former mining lands between Soweto and Johannesburg CBD. Based on the findings, there are various barriers which inhibit and threaten the construction of houses on former mining lands. These barriers, exposed by the findings of this report are radon, mine dust - both of which pose a serious health risk to residents if exposed to it for a long period of time - high prices of land, inadequate funding for housing subsidies and the National Nuclear Regulator’s too strict and uncompromising stance on housing construction on contaminated lands. The conclusion drawn by this report is that the government, owners of former mining land and the National Nuclear Regulator need to co-operate and work together towards finding a common ground in order to enhance the possibility of a total removal of these barriers, so that the previously marginalized citizens can afford to own houses closer to the Central Business District of Johannesburg.Item IT Portfolio Management: Barriers to Adoption and Strategies for Overcoming Them.(2007-02-15T13:41:33Z) Enoch, Clive N.As organisations continuously attempt to do more with less, Chief Information Officers (CIOs) must manage their portfolio of IT investments more effectively and efficiently. In order to achieve this, CIOs can adopt a portfolio management approach; however, there are barriers to the adoption to IT portfolio management. The purpose of this research was to explore the barriers to adoption of IT portfolio management. The barriers were identified by respondents from various sectors and across various levels in their organisations and then ranked in order to determine the most critical factors that impede adoption of IT portfolio management. Data was collected using the Delphi ranking type method, and targeted at CIOs, IT executives, and project managers. The questionnaire was designed to identify perceptions of the most significant barriers to IT portfolio management adoption and strategies for mitigating the effects of these barriers were drawn from the literature. The rank order of 11 barriers was determined from the individual ratings and rank orders of 38 respondents in the final phase with ‘the lack of executive sponsorship, support, and understanding of IT portfolio management’ being ranked as the most critical barrier.
