Effective and orderly software development has become a key issue in the management of data processing. The term software is recognized as meaning more than just programs. It encompasses the machines, people, and procedures that surround and are integral to a system. This expanded view of software and the need for its efficient development in an increasingly complex environment have given rise to the field of software engineering, which may be defined as the growing set of disciplines and procedures that facilitate the dependable development and maintenance of software systems. This issue of the IBM Systems Journal focuses on application development and the broader concept of software engineering.
