Questions

Extreme Programming (XP)

Acceptance Tests

  • Defined by customers to focus on overall system features and functionality.

  • Visible and reviewable by the customer.

Manual Tests

  • Perform by testers to detect software defects manually.

  • Used for real-time problem solving and quality assurance.

Pair Programming

  • Provides real-time problem solving and quality assurance.

  • Keeps end users focused on issues.

Coding and Unit Tests

  • After developing user stories and preliminary design work, XP teams first build unit tests.

  • These tests guide the coding process for the upcoming release.

Advantages of Unit Tests in XP

  • Encourage regression testing strategies.

  • Promote a smoke-testing environment ensuring that new changes don’t break existing functionality.

  • Allow developers to detect issues early and ensure code reliability.

  • Facilitate effective refactoring.

Framework Activities of XP

  • Main activities include:

    • Planning

    • Designing

    • Coding

    • Testing

  • Non-applicable activities: Deploying.

Project Velocity

  • Measures the number of user stories completed in a set time frame.

  • Aids in estimating shipping dates and scheduling future releases.

Continuous Integration Strategy

  • Benefits include:

    • Uncovers errors early in the development lifecycle.

    • Helps avoid compatibility and interface problems.

Scrum Methodology

Framework Activities of Scrum

  • Key activities include:

    • Requirements gathering

    • Analysis

    • Design

    • Evolution

    • Delivery

Daily Scrum Meetings

  • A 15-minute event scheduled to align team activities for the day.

Sprint Backlog

  • Represents a subset of the product backlog.

  • Changes can be introduced during normal development, contrary to common myths.

Benefits of Scrum Meetings

  • Foster knowledge sharing among team members.

  • Help identify potential problems early.

  • Promote a self-organizing team structure.

Agility in Software Development

  • Agile principles emphasize flexibility and responsiveness to change.

  • Promote regular feedback and adaptations based on stakeholder needs.

Principles of David Hooker

  • Design work considering its future use and maintenance.

  • Avoid complexity in design to enhance understandability.

  • What you produce is meant for others to use, prioritizing usability in designs.

Historical Context of Agile Processes

  • Developed as a counter to lengthy traditional software processes.

  • Emphasizes iterative advancements and regular communication with stakeholders.

Testing and Prototyping

  • Prototyping is critical for gathering user feedback and understanding requirements.

  • Successful prototyping requires clarity in identifying core features.

Maintenance in Software Development

Types of Maintenance

  • Adaptive Maintenance: Adjusting software for changing requirements post-delivery.

  • Perfective Maintenance: Adding new features and improving code quality.

  • Corrective Maintenance: Bug fixing and addressing software issues post-deployment.

Estimation Guidelines

  • When estimating resources, factor in:

    • Type of project

    • Experience of the development team

    • Types of components involved.
