    Study Notes

    Introduction to Software Engineering

    • This module covers defining software engineering, its evolution, and key characteristics of good software.

    What is Software Engineering?

    • The systematic process of developing and maintaining software systems using engineering principles.
    • It ensures software is efficient, reliable, and easy to maintain.
    • Focuses on creating well-defined structures to improve software quality.

    Evolution of Software Engineering

    • Initial and Chaotic Stage: Software development lacked structure.
    • Structured Programming (1970s): Introduced well-defined program structures and control flow.
    • Official Field of Study (1980s): Became a formal discipline.
    • Agile Methods (1980s): Emphasis on flexibility, collaboration, and quick iterations to address limitations of traditional methods.
