Classify software engineering. ins. Software engineering is a discipline whose aim is the production of quality software, software that delivered on time, within budget, and that satisfies its requirements. The scope of software engineering cludes study of software process, development/management principles, techniques, tools and notation. | lyftware engineering can be classified as in following number of steps : 1. Adopting a systematic and organised approach to all aspects of software development. 2. Using appropriate tools and techniques depending on : a, The problem to be solved b.. The development constraints c. The resource available. 3. Understand and communicate processes for improved software development within their organisation. 4, Effective teara members and/or leaders. Technical or more managerial personnel depending on organisational need.
