What is the main purpose of pair programming in XP?
To accelerate deployment to production
To increase code quality and reduce defects
To replace written documentation
To minimize project costs
Pair programming in XP involves two developers working together at one workstation to share knowledge, catch errors early, and improve code quality. This collaboration helps find defects faster and fosters collective code ownership. It reduces the need for extensive code reviews later in the cycle. Learn more
In XP, what is the primary role of the "Customer"?
Prioritizing features and clarifying requirements
Writing and merging code
Designing the system architecture
Managing the development team's sprint tasks
The on-site customer in XP is responsible for prioritizing the backlog, clarifying requirements, and making trade-off decisions during the Planning Game. This ensures the team builds what has the highest business value first. Having a real customer available improves feedback loops and reduces misunderstandings. Learn more
Which of the following is NOT an XP practice?
Continuous Integration
Simple Design
Collective Code Ownership
Sprint Planning
Sprint Planning is a Scrum practice, not part of Extreme Programming's original practices. XP includes practices like Pair Programming, Test-Driven Development, Continuous Integration, and Collective Code Ownership. Understanding the distinction helps teams choose the right agile framework. Learn more
What is the name of the XP practice where requirements are written on cards?
Feature Cards
Use Cases
User Stories
Story Cards
XP uses User Stories written on index cards to capture functional requirements in a lightweight, negotiable format. These cards drive the Planning Game and iteration planning by focusing on small, testable pieces of functionality. They encourage conversation between developers and customers. Learn more
In XP, what does TDD stand for?
Time-Driven Deployment
Technical Design Definition
Task-Driven Delivery
Test-Driven Development
Test-Driven Development (TDD) is the practice of writing automated tests before writing the minimal code to pass them. This ensures that code is testable, modular, and free of regressions. TDD fosters better design through small, incremental steps. Learn more
How frequently does XP advocate integrating code?
Multiple times per day
Once per week
Once per iteration
Only at major milestones
XP recommends continuous integration, meaning developers integrate and build the system multiple times per day. Frequent integration catches conflicts early, provides fast feedback, and reduces the risk of large integration issues. Automated builds and tests support this practice. Learn more
Which XP practice uses a "spike" for design experimentation?
Continuous Design
Iteration Zero
Spike Solution
Refactoring
A Spike Solution is a time-boxed experiment to research or prototype a problem area and reduce uncertainty before committing to a design. It helps teams choose an implementation approach with minimal overhead. Results are often thrown away or turned into real code afterward. Learn more
What is the ideal size of an XP team?
2-4 people
15-20 people
5-9 people
10-12 people
XP emphasizes small, cross-functional teams of about 5 - 9 members to maximize communication, collaboration, and shared responsibility. Teams smaller than five may lack necessary skills, while larger teams can suffer communication overhead. This range balances agility and capacity. Learn more
In XP, what distinguishes velocity from throughput?
Velocity measures code coverage; throughput measures story points
Velocity tracks story points per iteration; throughput counts completed items per time unit
Velocity measures team mood; throughput measures defect rate
Velocity is a financial metric; throughput is a quality metric
Velocity in XP is the average number of story points completed per iteration, guiding forecasting and iteration planning. Throughput is the count of items finished over a period, offering a simpler, count-based measure. Both help teams understand productivity but use different units. Learn more
What purpose does the "10-minute build" rule serve?
To limit the number of features per release
To ensure documentation is updated
To enforce pair programming sessions
To guarantee a rapid feedback loop for integration
The 10-minute build rule dictates that the entire system should compile, test, and produce a build in under ten minutes. This fast build time provides quick feedback on integration issues, encourages frequent integration, and reduces context-switching for developers. Learn more
How does XP handle refactoring debt in large codebases?
By performing continuous refactoring as part of daily development
By deferring all refactoring to a maintenance phase
By using external tools to refactor automatically
By scheduling dedicated refactoring iterations monthly
XP promotes continuous refactoring integrated into everyday coding rather than large, separate refactoring efforts. This keeps the codebase clean, design simple, and reduces technical debt over time. Developers refactor as soon as they see improvements, supported by comprehensive automated tests. Learn more
What strategies does XP recommend for scaling practices in multi-team projects?
Enforcing a strict code freeze between teams
Centralizing all decision making in a single architect role
Using quarterly manual integrations to reduce overhead
Implementing Communities of Practice to share knowledge across teams
XP itself doesn't prescribe heavyweight scaling frameworks but recommends creating Communities of Practice so developers across teams share techniques, standards, and solutions. This fosters cohesion and consistent practices without centralizing authority. Coordinated planning games and shared integration also help. Learn more

Study Outcomes

  1. Understand Core XP Principles -

    Define Extreme Programming values like simplicity, feedback, and courage to see how they guide iterative, customer-focused development.

  2. Identify Key XP Practices -

    Recognize essential XP techniques such as pair programming, test-driven development, and continuous integration to improve code quality and team collaboration.

  3. Differentiate XP from Other Agile Frameworks -

    Contrast XP practices with broader Agile approaches to understand when and why to apply XP-specific methods in software projects.

  4. Analyze Common Agile XP Questions -

    Break down Agile XP questions by topic and intention, sharpening your ability to interpret and answer quiz items accurately and efficiently.

  5. Apply XP Concepts to Real-World Scenarios -

    Use XP principles to choose appropriate practices in hypothetical development situations presented in the quiz.

  6. Prepare for an XP Methodology Test -

    Familiarize yourself with typical test structures and question formats in XP certification quizzes to boost your confidence and readiness.

Cheat Sheet

  1. Pair Programming -

    Pair programming is a core XP practice where two developers share one workstation, with one "driver" writing code and one "navigator" reviewing in real time. Studies from the University of Cambridge show this can cut defect rates by up to 15% and boost knowledge transfer. Remember "Two brains are better than one" to ace your Extreme Programming quiz!

  2. Test-Driven Development (TDD) -

    TDD follows the Red-Green-Refactor cycle: write a failing test (Red), write just enough code to pass (Green), then clean up (Refactor). Kent Beck's original XP book and IEEE articles confirm TDD improves code design and lowers bug counts by 40 - 90%. Use the mnemonic "Fail, Pass, Polish" to nail your XP methodology test.

  3. Continuous Integration (CI) -

    CI requires committing code frequently - at least once daily - into a shared repository with automated builds and tests, as recommended by the Agile Alliance. Carnegie Mellon's Software Engineering Institute reports that teams practicing CI find bugs 30% faster. Think "CI = Commit Immediately" for smoother XP certification quiz prep.

  4. Collective Code Ownership -

    In XP, any developer can modify any part of the codebase, reducing bottlenecks and encouraging team responsibility. According to research published in the ACM Digital Library, this practice boosts code quality and team morale. Keep in mind "Our Code, Our Responsibility" when tackling Agile XP questions.

  5. Sustainable Pace & Iteration Planning -

    XP recommends a 40-hour workweek with fixed-length iterations (usually one to two weeks) and story point estimation, often using the Fibonacci sequence. The University of Helsinki's agile curriculum shows sustainable pace prevents burnout and maintains productivity. Recall "Steady Sprint Wins" for your next XP practices questions.
