Common PSM I Exam Mistakes and How to Avoid Them
Introduction
The Professional Scrum Master™ I (PSM I) assessment rewards deep understanding of the Scrum Guide and solid time management. Below are the most frequent mistakes and practical ways to avoid them. 👊
1) Poor time management
With 80 questions in 60 minutes, you have under 45 seconds per item. Spending too long on a single question reduces your overall score potential.
- ✅ Tip: work in two passes. Answer clear items first; flag doubtful ones and revisit at the end.
- ⏱️ Track progress: aim for ≈ 20 questions every 15 minutes.
2) Treating Scrum as prescriptive
Scrum is empirical: transparency, inspection, adaptation. Relying on rigid checklists often leads to wrong answers.
- ✅ Value small Sprints, feedback, and continuous improvement.
- 📘 Mentally reference the Scrum Guide, not local practices or specific tools.
3) Mixing roles and accountabilities
Typical errors: assigning people-management to the Scrum Master, or giving operational work of the Developers to the Product Owner.
- ✅ Boundaries: PO maximizes product value; Developers create the Increment; SM enables Scrum and removes impediments.
4) Weak Definition of Done (DoD)
The DoD safeguards Increment quality. Confusing it with Definition of Ready or a generic checklist causes mistakes.
- ✅ DoD → completeness of the Increment; it applies to all work, not optional.
5) Underestimating the Sprint Goal
The Sprint Goal aligns focus during the Sprint. Subtle items test whether you use it as a decision constraint.
6) Multi-select items: incomplete selections
Some questions require multiple correct answers. Selecting just one marks the item wrong.
- ✅ Always read instructions: Select all that apply. Double-check before submitting.
7) True/False traps
Terms like always, never, must can signal extreme statements not aligned with the Scrum Guide.
8) Terminology & Scrum Glossary
The assessment is in English: terms like commitment, accountability, artifact carry precise meaning.
9) Product Backlog vs Sprint Backlog
A common mix-up: the Product Backlog belongs to the product; the Sprint Backlog is the Developers' plan to achieve the Sprint Goal.
10) Skipping retrospection on mistakes
Doing many simulations without reviewing errors limits learning.
- ✅ After each simulation, categorize mistakes (roles, events, artifacts, empiricism) and review accordingly.
Point-saving strategies
- 📝 First 5 minutes: scan, answer the sure ones, flag doubts.
- ⏱️ Last 3–5 minutes: review only the most critical flags.
- 📘 Mentally quote the Scrum Guide: if a practice isn't mentioned, be cautious.
