One of the major goals of software engineering is to control the development and maintenance of software products. With the growing use and importance of the Ada programming language, control over the software life cycle of Ada systems is becoming even more important. Software complexity metrics have been developed to aid software engineers in the design and development of software systems. This research defines metrics for Ada and uses an automated analysis tool to calculate them. This tool can be used by the software engineer to help maintain control over Ada software products. The validation of this tool was performed by analyzing a medium-sized commercial Ada product. The flow of control and flow of information through the use of Ada packages can be measured. The results show that software complexity metrics can be applied to Ada and produce meaningful results.
