Comprehensive and Detailed In-Depth Explanation:
Extreme Programming (XP) emphasizescontinuous feedback, early testing, and adaptive planning. When discrepancies arise, XP encouragesidentifying root causes and taking corrective actionswithout delaying value delivery.
Option D: Run a spike, identify what went wrong during implementation, and request a change to enhance value delivery (Correct Answer).
* Aspikeis a time-boxed research activity used toexplore a problem, test assumptions, and mitigate uncertaintyin XP methodology.
* By running a spike, the teamanalyzes what went wrongin implementation and applies the findings to ensurefuture iterations align with customer needs.
* The PMI-RMP Guide states that "proactive risk response planning helps teams course-correct and maintain delivery momentum" (PMI-RMP Exam Prep Study Guide, 2021, p.142).
* TheAgile Practice Guidesupports the use of spikes, highlighting that "spikes allow agile teams to validate uncertainties in requirements, leading to more informed decision-making" (PMI & Agile Alliance, 2017, p. 89).
Option A: Release this version and leave changes to be done at the end of the project phase (Incorrect).
* XP emphasizescontinuous improvementandearly defect resolutionrather than postponing fixes.
* Leaving changes until latermay increase technical debtand reduce user satisfaction.
Option B: Arrange a workshop where all ideas will be discussed and take corrective actions ensuring value delivery (Partially Correct but Not the Best Answer).
* While workshops help gather feedback, they do not providetechnical validationof what went wrong.
* Aspike (Option D)is a better approach because it directly investigates the issue and leads to actionable changes.
Option C: Ask the development team to brainstorm and come up with suggestions that will improve the delivery date (Incorrect).
* Brainstorming maygenerate ideasbut does notanalyze the root causeof the discrepancies.
* Without a structured approach like aspike, there is a risk of guessing rather than using data-driven solutions.
Final Verdict:The best answer isD (Run a spike, identify what went wrong during implementation, and request a change to enhance value delivery)because aspike provides empirical insights, leading to more effective corrective actions.
