    • Software engineering is a branch of engineering focusing on the evolution of software using well-defined scientific principles, techniques, and procedures
    • The result of software engineering is reliable software products
    • Software engineering is required to manage large software, for scalability, and for cost management
    • Better software development procedures lead to higher quality software products

    Need of Software Engineering

    • Higher rate of progress in user requirements and the environment of software is causing the need for software engineering principles, requiring a more scientific approach
    • Programming is becoming extensive
    • Software procedures need to be based on scientific and engineering ideas to effectively adapt to evolving software
    • The cost of programming remains high if proper processes are not used
    • Software is continually growing and adapting, which requires ongoing upgrades and quality management

    Importance of Software Engineering

    • Reduces complexity by dividing problems into smaller, manageable units
    • Minimizes the cost by focusing on necessary elements
    • Shortens development time through well-defined processes
    • Helps manage large-scale projects and provides more scalable solutions
    • Creates reliable software with emphasis on tests and maintenance
    • Enhances software effectiveness and adherence to standards

    Software Engineering Processes Models

    • Waterfall Model: A linear and sequential approach where each phase must be completed before the next can begin.
      • Requirement gathering and analysis
      • System design
      • Implementation
      • Testing
      • Deployment
      • Maintenance
    • V-Model: An extension of the waterfall, where testing stages correspond to development phases (verification and validation)
    • Incremental Model: Developing software in increments, releasing a functional module in every release,
    • Iterative Model: An approach that delivers a working product early in the process, then revisits and refines the product over a series of iterations.
    • Spiral Model: An evolutionary model that repeatedly refines and develops a prototype through numerous iterations
    • Rapid Application Development (RAD) Model: Using automated tools to design and create the product.
      • Business modeling, data modeling, process modeling, prototyping, and testing
    • Prototyping Model: A simplified version of the final product used to gather feedback from users.
