Software Engineering Lec#2

Software engineering explains two aspects:
• Engineering discipline: The engineers apply theories, methods, and tools where these are appropriate. However, they use them selectively and always try to discover solutions to problems even when there are no applicable theories and methods. Engineers also recognize they must work to organizational and financial constraints so they look for solutions within these constraints.
• All aspects of software production: Software engineering is not just concerned with the technical processes of software development. It also includes activities such as software project management and the development of tools, methods, and theories to support software production.
Software engineering is important for two reasons:
1. Needing to produce reliable and trustworthy systems. Thus, individuals and society rely on advanced software systems.
2. It is usually cheaper, in the long run, to use software engineering methods and techniques for software systems rather than just write the programs as if it was a personal programming project.
