Large fixed price projects planning and analysis
Král, Miroslav ; Chlapek, Dušan (advisor) ; Reich, Pavel (referee)
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.

Software Estimation
Surňák, Peter ; Buchalcevová, Alena (advisor) ; Stanovská, Iva (referee)
This thesis deals with software estimation, describes individual methods which may be used for constructing estimates in terms of effort, time and costs. It also deals with quality of estimate, the way it is used, the process of selection of the right method and other consequences. The main goal of thesis is creating a compact overview of currently known and used methods and approaches to constructing estimates. As a secondary target comes an example of practical use of estimate on a simulated project, where the way of choosing estimating method is presented, based on project attributes such as size, current stage of project or project type. For achieving these intentions, it is important to first set up basic framework of basic terms such as estimate, estimating, project and software project. Apart from just defining these terms, there are some necessary interrelations which must be explained before anything else. Another step is creating categorization of particular methods, their description, restrictions and suitable uses. The quality of an estimate, including factors which may bias, degrade or improve it, is another step towards final goal. Consequences, which may arise when wrong estimate has been provided, are one more piece of mosaic to this work. Lastly, case study demonstrate how to choose from estimating methods and use them on particular project. The expected benefits of the thesis are mainly in summarizing of existing approaches to the art of estimating broken down to categories, as well as list of principles and factors which affects an estimate and the ways estimates influence the project (in either positive or negative direction).
