Cost estimation of software development and control of the cost during the development, are difficult due to the lack of useful cost figures from previous projects, and consequently due to the lack of an accurate cost estimation and management method. This report describes the results of the first phase of a study to develop a software cost database. This cost database will be used to develop such an accurate cost estimation method and to support cost management. The study is performed under contractnumber 18T0 of the Netherlands Agency for Aerospace prograjns (NIVE). During this first phase, a literature survey has'been performed on software cost estimation techniques and on already available cost data bases. This survey, together with the experience, available at NLR, has led to a proposal for a cost estimation method. To support this method, kj cost factors have been defined. It is felt that the clear definition of those cost factors will be of main importance for the usefullness of the method. The next phase of this study will be the implementation of a cost database, which will contain data about these kj cost factors. This data will be gathered from running projects. The cost database will ultimately be used to determine the constants of the proposed cost estimation method.
