This paper introduces an approach for the acquisition of requirements centered on the idea of organizing requirements in requirement clusters. The acquisition of requirements is one of the first steps in the development process and is a key process for all following steps. The quality and quantity of the requirements acquired determine costs, necessary time and iterative steps needed in the whole development process. Due to the fact that the acquisition of requirements happens under vastly different circumstances in every project, the level of process standardization is very low. This low level of standardization results in a variety of problems: unnoticed implicit requirements, misunderstandings caused by non-standardized use of terms and incomplete or incorrect requirements. Clustering of requirements is a known concept, but up to now is used only after the process of acquisition to structure the requirements for further use. The use of requirement clusters in this paper aims at increasing the standardization and the quality by using requirement clusters in the process of requirement acquisition.
