Abstract: This dissertation aims at developing a neural network (NN) model that can learn and project manpower of the information technology (IT) sector for the years ahead based on previous years performance factors/variables (such as IT vacancy rate, IT manpower growth rate, IT wastage rate, emigrant growth rate, economic growth rate, wages/earnings index, labour force participation rate, and employment growth rate) which might have an influence on the IT manpower requirement. The effectiveness of the NN model is evaluated by the comparison of the statistical model in relation to earlier IT manpower survey data and its forecast. The statistical model is developed using Pascal language whereby the random fluctuations in past data can be effectively smoothed out by the weighted exponential process to give a trend. An adaptive filtering method is used to devise an optimum solution for manpower projection in the IT sector. Both neural network and statistical models are amenable to processing by an IBM-compatible personal computer whereby the optimum trend (i.e. minimum absolute or mean squared error) can be obtained automatically, and the forecast can otherwise be optimized to suit decisions based on assumption of future market trends or other relevant information. The time series and the computational speed in both methods are described and compared. By going through the whole process of system development, the neural network and statistical models can be deeply understood and investigated. Advantages and risks of using these models will also be discussed in this dissertation. As IT is a rapidly changing and developing field, an accurate manpower projection model is required by the government and other organizations, together with other relevant information, for the formulating of IT education policies and plans. Other than the prediction on rise and fall of companies, products and technologies, I believe the underlining trends in the growth of IT manpower will continue as described in this dissertation.
