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.
