The origins of each IT Project are always in business needs or in the necessity for a product. Improvement or automatisation of the business process, expansion from the functionality of the Software-System, opening of new roads for clients - these are examples of different business needs. Each business need has to be exactly explored, analysed and adjusted to a specific situation. This is exactly the domain of a Business Analyst. The achievement of a Project depends on the capacities and the experience of the Business Analyst. He has to assemble precise needs and transform them into a solution. Thereto, specific skills and standard knowledge are essential.
