Overview¶

PMI-ACP is PMI's certification proving broad competency across multiple agile methodologies (not just Scrum) — including Kanban, Lean, XP, and hybrid approaches. Unlike Scrum-specific certifications, PMI-ACP tests breadth: the exam draws from a wide reading list spanning several agile frameworks and mindsets.

Who it's for: Project managers, PMPs looking to add an agile credential, and practitioners who work in mixed/hybrid environments rather than pure Scrum shops.

Eligibility (per PMI): Requires general project experience, agile project experience, and 21 contact hours of agile training — verify current requirements directly on PMI's website, as they are updated periodically.

Core Topics Breakdown (PMI-ACP Domains)¶

1. Agile Principles and Mindset¶

• The Agile Manifesto's four values and twelve principles — know them verbatim, as exam questions test nuance (e.g., "individuals and interactions over processes and tools," not "instead of").
• Servant leadership vs. traditional command-and-control project management.

2. Value-Driven Delivery¶

• Prioritization techniques: MoSCoW, Kano model, weighted shortest job first (WSJF).
• Minimum Viable Product (MVP) and incremental value delivery.
• Earned value management adapted for agile contexts.

3. Stakeholder Engagement¶

• Techniques for eliciting and maintaining active stakeholder participation (unlike waterfall's front-loaded requirements gathering).
• Wireframes, personas, and story mapping as stakeholder communication tools.

4. Team Performance¶

• Tuckman's stages of team development (Forming, Storming, Norming, Performing, Adjourning) applied to agile teams.
• Emotional intelligence and self-organizing team dynamics.

5. Adaptive Planning¶

• Rolling wave planning, progressive elaboration.
• Relative estimation: story points, T-shirt sizing, and why they resist direct comparison to hours.
• Release and iteration planning across Scrum, Kanban, and XP.

6. Problem Detection and Resolution¶

• Risk-adjusted backlog and risk burndown charts.
• Escaped defects and their root-cause analysis in an agile cadence.

7. Continuous Improvement (Product, Process, People)¶

• Retrospective techniques beyond the standard format (e.g., Start-Stop-Continue, sailboat retrospective).
• Kaizen and value stream mapping from Lean.

Study Tips¶

• The PMI-ACP exam is framework-agnostic — don't over-index on Scrum vocabulary. Expect XP practices (pair programming, test-driven development, continuous integration) and Kanban concepts (WIP limits, cumulative flow) at similar weight.
• Build a comparison table of terms across frameworks (e.g., "Iteration" in XP/Scrum vs. "no fixed iteration" in Kanban).
• Practice situational judgment questions — PMI exams favor the "most appropriate next action" format over rote recall.

Common Pitfalls¶

• Assuming PMI-ACP is "Scrum with a PMI badge" — it explicitly tests Lean, Kanban, and XP knowledge too.
• Confusing velocity (Scrum) with throughput/cycle time (Kanban) — these are measured differently and answer different questions.
• Underestimating the reading list breadth; PMI-ACP historically references numerous source texts across methodologies.

Further Practice¶

Take a real work item and estimate it three ways: story points, T-shirt size, and ideal hours. Note where each method breaks down.
