PREVIEW OUTPUT 1: Analyzing the question, it is asking about three practices associated with Extreme Programming (XP). XP is one of the agile methodologies that focuses on engineering practices to improve the quality and responsiveness of software development.
A. Defect correction - While fixing defects is important in any software development process, "Defect correction" as stated isn't a specific practice of XP. - ❌ Incorrect - Source: General knowledge of XP practices.
B. Test-driven Development (TDD) - TDD is a core practice of XP where code is developed based on tests that fail initially. As the code gets developed, the tests pass. This ensures code correctness and robustness. - ✅ Correct - Source: "SAFe® 5.1 Distilled: Achieving Business Agility with the Scaled Agile Framework" by Richard Knaster and Dean Leffingwell.
C. Solution context - "Solution context" is not recognized as a specific practice of XP. - ❌ Incorrect - Source: General knowledge of XP practices.
D. Continuous Integration - Continuous Integration (CI) is a practice in XP where code is regularly integrated and tested to detect integration errors as quickly as possible. - ✅ Correct - Source: "SAFe® 5.1 Distilled: Achieving Business Agility with the Scaled Agile Framework" by Richard Knaster and Dean Leffingwell.
E. Establishing roles - While roles are crucial in any development process, "Establishing roles" as mentioned is not a specific practice tied to XP. - ❌ Incorrect - Source: General knowledge of XP practices.
F. Pair programming - Pair programming is another core XP practice where two developers work together at one computer, with one typing and the other reviewing or guiding. This ensures quality and shared knowledge. - ✅ Correct - Source: "SAFe® 5.1 Distilled: Achieving Business Agility with the Scaled Agile Framework" by Richard Knaster and Dean Leffingwell.
Summary: The three practices of Extreme Programming (XP) are:
- B. Test-driven Development
- D. Continuous Integration
- F. Pair programming
Degree of Certainty: 100%
PREVIEW OUTPUT 2: Analyzing the question, it is centered on how a team demonstrates its progress in the context of SAFe.
A. With PI Objectives - PI (Program Increment) Objectives are a set of goals for a Program Increment. While they help set the direction and expectations for a PI, they don't demonstrate the ongoing progress of a team. - ❌ Incorrect - Source: "SAFe® 5.1 Reference Guide: Scaled Agile Framework® for Lean Enterprises" by Dean Leffingwell.
B. With Burn-up charts - Burn-up charts visually represent the amount of work completed over time compared to the total scope of work. This allows teams and stakeholders to see the team's progress towards completing a body of work. - ✅ Correct - Source: "SAFe® 5.1 Reference Guide: Scaled Agile Framework® for Lean Enterprises" by Dean Leffingwell.
C. With an Iteration Review - An Iteration Review is an event where teams demonstrate the working system to stakeholders. While it's an avenue to show the outcome of the work, it's not the primary tool used to demonstrate ongoing progress. - ⚠️ Partially correct - Source: "SAFe® 5.1 Reference Guide: Scaled Agile Framework® for Lean Enterprises" by Dean Leffingwell.
D. With team cadence - Cadence refers to the predictable rhythm at which a team operates, but it doesn't show the team's progress. It ensures regularity but doesn't depict the forward movement of work. - ❌ Incorrect - Source: "SAFe® 5.1 Distilled: Achieving Business Agility with the Scaled Agile Framework" by Richard Knaster and Dean Leffingwell.
Summary: The best way for a team to demonstrate progress is:
- B. With Burn-up charts
Degree of Certainty: 95% (Given the options presented, Burn-up charts are the most accurate means to demonstrate progress, though Iteration Review is also relevant but not the primary means to show continuous progress).
PREVIEW OUTPUT 3: Analyzing the question, it pertains to the requirements of Iteration Planning within the context of SAFe.
A. It is only required for every third Iteration - This statement is incorrect. Iteration planning is essential for every iteration to align the team on the work and objectives for that specific iteration. - ❌ Incorrect - Source: "SAFe® 5.1 Reference Guide: Scaled Agile Framework® for Lean Enterprises" by Dean Leffingwell.
B. It is required for every Iteration to enable fast learning cycles - Iteration planning occurs at the beginning of each iteration. The purpose is to define the iteration goals and the work required to achieve them. By doing so, teams can have short, fast learning cycles and can adapt quickly. - ✅ Correct - Source: "SAFe® 5.1 Reference Guide: Scaled Agile Framework® for Lean Enterprises" by Dean Leffingwell.
C. It is required for component teams but may not be required for feature teams that have no dependencies on other teams - This statement is misleading. Regardless of whether a team is a component team or a feature team, and irrespective of dependencies, iteration planning is required for every iteration. The nature of the dependencies might change the details of the planning, but not the need for the planning itself. - ❌ Incorrect - Source: "SAFe® 5.1 Reference Guide: Scaled Agile Framework® for Lean Enterprises" by Dean Leffingwell.
D. It is not required for teams that consistently meet their PI Objectives - Meeting PI objectives is a good indicator of the team's performance, but it doesn't remove the need for iteration planning. Every iteration has unique objectives and work, and planning is essential to define and align on these. - ❌ Incorrect - Source: "SAFe® 5.1 Reference Guide: Scaled Agile Framework® for Lean Enterprises" by Dean Leffingwell.
Summary: The true statement about Iteration Planning is:
- B. It is required for every Iteration to enable fast learning cycles
