Abstract for: Influence of Projects’ Size on a Professional Service Firm Performance

In the presented work we devote to creating a computer model of a professional service firm using the theory of business modeling. The whole model was programmed using the application Vensim. Another part of this work was to use this model to answer some key questions about the professional service firms. We were studying how projects’ size influences company’s performance. We have also identified optimal project size for our model settings. Such model could then be used for better understanding patterns of companies in the professional service industry and we can use it to manage the company more effectively in this environment.
