This paper describes an on-going field study to examine the differences and similarities of software maintenance in the Object Oriented and conventional 3GL programming environments. We expect our results will show that the maintenance process will differ between environments in that programmers working in Object Oriented environments may need to spend more time understanding and coordinating their changes and less time making the changes
