Study Notes

Chapter 1: Introduction to Software Engineering Concepts

This chapter introduces fundamental concepts of software engineering.
Software products are large and complex, demanding analysis and synthesis in their development.
Analysis involves breaking down a problem into smaller, understandable pieces, prominently using abstraction
Synthesis involves composing, building a software system from smaller units. Composition is a challenging aspect of the development process.
A structured problem-solving approach comprises defining methods, tools and procedures for creating a software product.
Paradigms (e.g., object-oriented vs. structured) shape product development approaches.
Software engineering is a discipline, distinct from computer science, utilizing computer technologies to address problems.
Key stakeholders in software development are the customer, developer and the user.
Software process models, such as the capability maturity model (CMM), ISO 9000, and SPICE, are important for process improvement.
Software quality is characterized in various viewpoints (transcendental, user, manufacturing, product and value-based).
Software quality is assessed for product, process and in business context.
Key quality concepts, such as completeness, consistency, accuracy, and efficiency, and others are detailed in the McCall quality attributes model.
Software faults arise due to human errors which impact software system behavior through failures.
The success of software engineering is measured by its ability to perform tasks more effectively and deliver improved products.
Software failures, like the Ariane-5 rocket failure, highlight potential issues that need to be addressed through careful design and development processes.
Software reuse and reuse potential are key aspects of software design and engineering.
