Abstract
Cost estimation of software development and control of the cost dioring the development are difficult due to the lack of an accurate cost estimation and management method. For the development of such a method cost figures from previous projects are needed and these are not readily available. In order to improve this situation, a user-friendly method for the collection, storage and retrieval of software-cost data has been developed, with emphasis on aerospace software projects. Data is and will be collected regarding k'J welldefined cost factors, divided in 8 classes. It is felt that the clear definition of these cost factors will be of main importajice for the applicability of the collected data. When suitable data is available from completed projects, the impact of these factors on the software development cost can be estimated, thus leading to a more reliable cost estimation and cost management method. The paper describes the cost estimation method that will be calibrated by means of the collected data, the implemented data collection and retrieval system, called a software-cost database, and the use of this system as management tool during rxinning projects. For some projects, the cost database is already in use.
