Study Notes

Importance of Software Engineering

  • Complex systems require a disciplined approach for effective design, development, and management.
  • Historical context: Software Development Crises highlighted projects that were often late, over budget, unreliable, difficult to maintain, and performed poorly.
  • The term "software engineering" emerged from the 1968 NATO Software Engineering Conference to address the "software crisis."
  • Defined as an engineering discipline covering all aspects of software production, from initial system specification to ongoing maintenance.

Types of Software

  • Generic Products:

    • Stand-alone systems sold to any customer.
    • Examples include PC software for graphics, project management tools, and CAD software.
    • Specifications are owned by the developer, who also decides on software changes.
  • Customized or Bespoke Products:

    • Commissioned software tailored to a specific customer's needs.
    • Examples include embedded control systems and air traffic control software.
    • Specifications are owned by the customer, allowing them to dictate required changes.

Definition and Attributes of Software

  • Software encompasses computer programs and associated documentation, designed for specific clients or general markets.
  • Good software is characterized by:
    • Required functionality and performance delivery.
    • Maintainability, dependability, and usability.

Fundamental Software Engineering Activities

  • Activities include:
    • Software Specification: Defining what the software should do.
    • Software Development: Creating the software based on specifications.
    • Software Validation: Ensuring the software meets requirements and performs correctly.
    • Software Evolution: Updating and maintaining the software post-deployment.

Differences in Disciplines

  • Software Engineering vs. Computer Science:

    • Computer science focuses on theoretical foundations and principles.
    • Software engineering addresses the practicalities of developing and delivering software solutions.
  • Software Engineering vs. System Engineering:

    • System engineering encompasses all facets of computer-based systems, involving hardware, software, and process engineering.
    • Software engineering is a subset within the broader system engineering process.
