Information Technology and Software Development is a three credit load course for all the students offering Post Graduate Diploma (PGD) in Computer Science, Information Technology and other allied courses. Software Development is a major branch in computing and information Technology. A software development professional oversees the processes of software development, the management of software development project, the maintenance of the installed software in an organisation. For sometime the field has been dominated with what is the definitive process of software development. Furthermore there has been the running battle between professionals and managers on who should control a software development project. There is an attempt to classify it as any other project that an organisation handles hence anybody could manage it. Whereas others see it as a highly professional issue that requires high precision in design, management and implementation. However, software development is all involving. It involves the user (client) whose interest is paramount. The developing organisation and her professionals ( team)are of great importance. Therefore a successful exercise can only take place when all these variegated interests are harmonised.
