    Study Notes

    Agile Software Development

    • Agile development involves features, software requirements, user stories, and supplementary tasks like architecture definition and user documentation.

    Product Owner

    • A product owner is an individual or small group responsible for identifying product features, prioritizing them, and continuously reviewing the product backlog to ensure the project meets business needs.
    • The product owner can be a customer, product manager, or stakeholder representative.

    Scrum Terminology

    • Scrum is a daily meeting that reviews progress and prioritizes work for the day.
    • A ScrumMaster ensures the Scrum process is followed, guides the team, and interfaces with the company.
    • A ScrumMaster is not a project manager.
    • A Sprint is a development iteration, typically 2-4 weeks long.
    • Velocity is an estimate of how much product backlog effort a team can cover in a single sprint.

    Agile Manifesto

    • The Agile manifesto values individuals and interactions over processes and tools, working software over comprehensive documentation, customer collaboration over contract negotiation, and responding to change over following a plan.

    Principles of Agile Methods

    • Customer involvement is essential throughout the development process.
    • The software is developed in increments with the customer specifying requirements for each increment.
    • The skills of the development team should be recognized and exploited, with minimal prescriptive processes.
    • The system should be designed to accommodate changes and simplicity should be maintained in both the software and development process.

    Refactoring

    • Refactoring involves reorganizing class hierarchies, tidying up and renaming attributes and methods, and replacing inline code with program library calls.

    Test-First Development

    • Testing is central to XP, with tests written after every change.
    • XP testing features include test-first development, incremental test development from scenarios, user involvement, and automated test harnesses.

    Test-Driven Development

    • Writing tests before code clarifies requirements and ensures they are implemented correctly.
    • Tests are written as programs, executed automatically, and include checks for correct execution.
    • All previous and new tests are run automatically when new functionality is added.

    Customer Involvement

    • The customer helps develop acceptance tests for stories to be implemented in the next release.
    • The customer writes tests as development proceeds.
