Scrum.org assessments reward sound reasoning—not memorization. Here are books that provide strategic, principle-driven guidance for Scrum.org professional assessments, including PSM I, PSM II, PSPO I, PSPO II, and other related certifications.
Unlike conventional Scrum practice books or exam-preparation guides, these books do not rely on memorization, large question banks, or attempts to simulate the assessments themselves. Instead, the series is designed to develop candidates' thinking when applying Scrum in complex, ambiguous real-world situations—the very capability Scrum.org assessments are intended to evaluate.
Compared to the cost of an assessment and the time invested in preparation, this book represents inexpensive insurance. By helping you align your thinking with how Scrum.org assessments are designed and evaluated, it reduces avoidable mistakes and increases your likelihood of passing. Even experienced practitioners often uncover subtle gaps in reasoning that this guidance helps correct before they appear on an assessment.
​
Why these books are different
Rather than relying on terminology, restating the Scrum Guide, or training candidates to recognize familiar question patterns, this series takes a fundamentally different approach. Each book focuses on why assessment questions are written the way they are, what they are actually testing beneath the surface, and how to reason through them using Scrum principles rather than habits, assumptions, or organizational norms. This approach does not become obsolete as assessments evolve or new questions are introduced.
Every volume in the series is grounded firmly in the Scrum Guide and reflects Scrum as it is intended to work—not as it is commonly implemented or adapted within specific environments. The guidance emphasizes empiricism, accountability, transparency, inspection, adaptation, and principle-based decision-making. Readers learn how to analyze questions through the lens of Scrum values, accountabilities, events, artifacts, and commitments.
​
Why you can trust these books
The series draws on the author's extensive experience teaching Scrum.org courses, observing thousands of assessment attempts, and personally taking the assessments nearly 50 times. Through this experience, clear and consistent patterns have emerged. Candidates rarely fail because they lack factual knowledge of Scrum. Instead, they struggle because they apply local practices, assumptions, or ingrained ways of thinking that conflict with Scrum’s intent. These books directly address those patterns and help readers recalibrate how they interpret and reason about Scrum scenarios.
While each book includes original practice questions to support learning, the primary purpose of the series is not to predict exam content or mirror assessment wording. Scrum.org assessments evolve, and resources that depend on static question patterns quickly become outdated. Instead, this series equips readers with a durable mental model—one that enables them to approach any assessment question with clarity, consistency, and confidence.
Strategic Guidance for the PSPO I™ and PSPO II™
Successfully passing the Professional Scrum Product Owner™ I or Professional Scrum Product Owner™ II assessment is not based on memorizing simulated questions—especially those that may already be outdated. Success comes from understanding how Scrum is intended to function and applying its principles deliberately when interpreting assessment scenarios. This book develops the reasoning discipline needed to approach the assessments with clarity, confidence, and professional rigor, helping you think more clearly about Scrum and increase your likelihood of passing.

Parallel Agile – faster delivery, fewer defects, lower cost

PA shares Agile’s emphasis on early coding and rapid feedback from executable software. Technical prototyping is used deliberately as risk mitigation — validating feasibility, clarifying requirements, and evaluating architectural options before significant investment.
​
Unlike many Agile approaches, PA does not rely on design-by-refactoring or unit-test-driven architecture. Instead, it applies a minimalist UML-based Agile/ICONIX design method centered on a domain model that improves team communication and partitions systems along use-case boundaries to enable true parallel development. PA aligns naturally with the Incremental Commitment Spiral Model (ICSM), supporting concurrent collaboration among systems engineering, development, and testing teams.
