    Study Notes

    Introduction to Software Engineering

    • Software engineering is a discipline concerned with all aspects of software production, from initial specification to maintenance.
    • Economies of developed nations are heavily dependent on software.
    • Software expenditure is a substantial portion of GNP in developed countries.
    • Software costs often exceed hardware costs.
    • Maintaining software is more expensive than developing it, especially for systems with extended lifespans.
    • Software project failure is often linked to increasing system complexity and not using appropriate software engineering methods.
    • The diversity of software systems necessitates a variety of methods and tools.

    Software Products

    • Generic products are marketed and sold to any customer, (e.g., PC software, CAD software).
    • Customized products are commissioned by a specific client to meet their unique needs, (e.g., embedded control systems, air traffic control).
