I.T portfolio management system entails the use of scoring model systems in rating projects whereby a list of criteria is developed whereby projects are rated on each criterion to yield attractiveness scores for each project and hence projects can be rated in relation to the attractiveness scores. There are different kinds of scoring systems; Celanese scoring model, Dupont scoring model, Exfo model and computer-based scoring model. Scoring models are very important and they are a source of data which is utilized in meetings whereby project attractiveness is compared to cut off criterion, thereby in portfolio review stage the outputs used in ranking the projects.Lack of physical evidence when testifying jeopardise the computer crime cases, relying on second hand information or hearsay may bring forth doubts on the evidence presented.
