    2.3.1 Agile Tester Skills
    ● Be positive and solution-oriented with team members and stakeholders
    ● Display critical, quality-oriented, skeptical thinking about the product
    ● Actively acquire information from stakeholders (rather than relying entirely on written specifications)
    ● Accurately evaluate and report test results, test progress, and product quality
    ● Work effectively to define testable user stories, especially acceptance criteria, with customer representatives and
    stakeholders
    ● Collaborate within the team, working in pairs with programmers and other team members
    ● Respond to change quickly, including changing, adding, or improving test cases
    ● Plan and organize their own work
    Continuous skills growth, including interpersonal skills growth, is essential for all testers, including those on Agile teams

    Software Definition
    Software is a collection of instructions and data that tell a computer how to work
    The computer (hardware) is able to execute the software. Each instruction causes
    the computer to carry out an operation - moving data, carrying out a computation,
    altering the control flow of instructions or manipulating hardware

    In a typical conventional computer system, the
    software is programmed by humans using an
    imperative language, which includes constructs
    such as if-then-else and loops. It is relatively
    easy for humans to understand how the system
    transforms inputs into outputs.
