Study Notes
Overview of Software Engineering
- Software engineering plays a crucial role in developed nations, impacting economies significantly.
- The growing reliance on software systems highlights the importance of effective software engineering practices.
Software Costs
- Software often exceeds hardware costs in terms of total computer system expenses.
- Maintenance costs of software can be significantly higher than development costs, especially for long-lived systems.
- Emphasis on cost-effective software development is essential due to high maintenance expenses.
Challenges of Software Project Failure
- Increasing system complexity necessitates faster delivery and the development of more advanced systems.
- Failure to implement software engineering methods can lead to increased costs and unreliable products.
Key Questions in Software Engineering
- What is software? Refers to computer programs and accompanying documentation, tailored for specific clients or the general market.
- Attributes of good software: Should deliver required functionality, be maintainable, dependable, and user-friendly.
- Differences between disciplines: Software engineering focuses on the practical aspects of production, while computer science emphasizes theory. System engineering encompasses both hardware and software development.
Key Challenges in Software Engineering
- The field faces challenges like handling increased diversity, demand for faster delivery, and the necessity for trustworthy software.
- Roughly 60% of software costs are allocated to development, with 40% dedicated to testing.
Software Product Types
- Generic Products: Stand-alone systems available to any customer, such as PC software or CAD tools.
- Customized Products: Developed specifically for individual customers, including systems like air traffic control software.
Product Specification Ownership
- In the case of generic products, the software developer retains specification ownership; in customized products, the customer owns the specification and dictates necessary changes.
Essential Attributes of Good Software
- Maintainability: Software must adapt to changing customer needs, crucial for remaining relevant.
- Dependability and Security: Software should be reliable and resistant to malicious attacks, ensuring safety and security.
- Efficiency: Software must utilize system resources judiciously, optimizing processing time and memory use.
- Acceptability: Designed products should be user-friendly, understandable, and compatible with existing systems.
Importance of Software Engineering
- Society increasingly relies on sophisticated software systems, making it vital to produce systems that are both reliable and economical.
- Long-term savings are often achieved through the use of software engineering methods rather than ad-hoc programming approaches.
