| Abstract [eng] |
One of main goals of this work was deep look at existing IT services financial models, which are build using chargeback model. Another goal - depending on this create my own abstract IT services financial model, which would depend on chargeback method. Firstly we need to know what the purpose of IT services financial models is and why we need model those using computers. The main and mandatory goal of IT financial model is identify IT services costs. Other optional goals are allocating costs and managing costs recovery. In real life we cannot start using new model quickly. It can make mistakes and it is very expensive. So in this approach we can see that computer-based modeling is very helpful. As I said earlier, the main view will be at chargeback model, because it is a new standard in financial IT services management. Chargeback uses ABC for cost identifying. It is different from traditional methods. The main difference is concentrating on activities rather than departments. It more accurately identifies services costs, but is more complex and more difficult to implement. At this work I discovered that we can use mixed IT services financial model. For fixed costs services we can use traditional models and for services with shared resources, like projects, better use chargeback. During the time of this work was projected and implemented abstract IT services financial model. System is build from few modules and at this work were developed only mandatory modules. Every concrete system must extend this functionality. I was focusing on few critical factors. At projecting I showed how system can be improved and harmonized with your own goals and other systems. |
