Plánování a analýza velkých projektů za pevnou cenu

A large number of different methods in the field of estimation of IS/IT projects have been developed in past years. Those methods should be used with regard to several factors. The choice and the application of an estimation method should take into consideration the current phase of each project and the wide variety of external factors, whose composition and intensity are very diverse and individual. The accuracy of the estimation considerably influences the success of the whole project. Therefore it is crucial to pay special attention to the mentioned phenomenon. The aim of this diploma thesis is to provide a comprehensive overview of the issue of the estimation of large projects for fixed price. The objective is particularly fulfilled by the provided overview and definitions of the chosen methods, the list of the most common mistakes and the interpretation of the results of an analysis concerning the portfolio of projects that were realised in an international company. The expected outcome of the diploma thesis is represented by the definition of the procedurally correct and comprehensive description of the creation of the price for a project with the fixed extent of work, which can be guaranteed with a reasonable rate of risk by a supplier. Another outcome of the thesis is the interpreted outputs of the analysis concerning the portfolio of projects realised by the international supplier of IS/IT products and services, which can be exploited for more effective estimations and project portfolio management.
