Many enterprises in Serbia are in the process of transition. Transitiveness is reflected in privatisation, market competitiveness strengthening and changes in the business philosophy. The “specific“ business performance over years in our country has brought to the situation where enterprises require the maximum engagement and increase of profitability in order to achieve the satisfactory results in production and distribution through the minimum investments. Nowadays, the enterprise management through implementation of the contemporary IT demands shifts within the very organisational structure of an enterprise, which would be based on information and tasks performed by the computer, while the employees would be focused exclusively on their own performance, i.e. to create new organisational shapes of the enterprise that should encourage implementation and concentration of the scientific achievements with the help of a more flexible structural organisation, and through giving bigger responsibilities and authorisations to individuals. The special role in positioning an enterprise on the market and sustainingincreasing the competitiveness is an everlasting process of innovations. Introducing a new product and increasing the productive variety is the priority of every successful enterprise. The task of this paper is to present the necessary steps needed to introduce a new product through investment and to look upon the comparative advantages after the introduction. The enterprise that we will present is the Public Enterprise for Undermine Coil Exploitation Resavica, which is a part of Coal Mine “Štavalj“.
