The project preparation assignments always have a development or project proposal in focus. The purpose of the project preparation activity is to analyse and elaborate these developments and project proposals in such a way that the documentation prepared by us represents real and relevant assistance for the project promoter in its management decisions linked to the project both in the preparation and the implementation phase. The outputs of the analyses are presented in all cases in the form of expert documentations. According to their specific purpose or content, these products can be development concepts, strategies, action plans, programmes, business and/or financial plans of a project proposal or territorial unit (e.g. a settlement). Still, the most common outputs of our project preparation assignments are feasibility studies of different focus and depth of details. We set as a target of every project preparation activity the possibly deepest analysis of the proposal, the elaboration of optimal financing methods, as well as the planning of sustainable and successful operation of the project.
