Scrum
312 bites tagged Scrum — interview questions with model answers, and 60-second explainers.
A high-priority story is too large for one sprint. What are the options?
This tests your ability to deliver incremental value. A good answer prioritizes vertical slicing (end-to-end functionality) over horizontal (task-based) splits. Discuss trade-offs of different splitting patterns.
Handling a user story too large for a sprint
This tests your grasp of vertical slicing and incremental value. A good answer involves collaborating with the PO, splitting the story into smaller, value-delivering slices, and negotiating scope.
What systemic impediments cause 'Zombie Scrum'?
Tests your ability to diagnose systemic issues beyond team-level Scrum mechanics. A great answer identifies four root causes: misunderstood purpose, no stakeholder involvement, fake continuous improvement, and low team autonomy. A red flag is blaming the team.
How do you handle non-functional requirements in a product backlog?
This tests your ability to integrate quality attributes (NFRs) into the agile workflow. Make them visible in the backlog, add them to the Definition of Done, and break them into testable sprint tasks. Red flag: treating NFRs as separate, non-sprint work.
Blocker vs. Impediment: Definitions and Escalation
Tests your grasp of Scrum terms and escalation. A blocker stops work; an impediment slows it. A good answer defines both, then outlines an escalation path for impediments: visualize, quantify impact, and engage leadership.
Which Scrum event is most critical for a failing team?
This tests your grasp of Scrum's empirical process. A great answer champions the Sprint Retrospective for team self-inspection and process adaptation. A red flag is blaming a role or picking an event without justifying it based on Scrum principles.
How does an EM's role change in an agile model?
This tests your grasp of servant leadership. A great answer explains the shift from directing work to enabling teams by building capabilities, removing impediments, and managing boundaries.
How Management's Role Evolves When Scaling Agile
This tests your grasp of servant leadership vs. command-and-control. A good answer contrasts traditional managers (directing work) with enabling managers (removing impediments, teaching problem-solving) as seen in LeSS.
What is an Architectural Runway and how do you maintain it?
Tests balancing intentional architecture with emergent design in SAFe. Define it as the tech foundation for near-term features, built via Enabler stories. You contribute by identifying and implementing these enablers.
How would you create a probabilistic forecast for a backlog?
This tests your grasp of probabilistic forecasting over single-date estimates. A good answer explains using historical throughput to run a Monte Carlo simulation, then presenting a range of dates with confidence levels (e.g., 50%, 85%).
How do you use a spike to de-risk a story?
This tests your ability to use agile spikes for targeted de-risking, not just vague research. A strong answer defines the specific question the spike will answer, proposes a strict time-box, and lists concrete deliverables like a decision or a better estimate.
Sprint Review vs. Sprint Retrospective: Purpose and Participants
Tests if you distinguish inspecting the product (Review) from the process (Retro). A good answer defines purpose (what vs. how), participants (stakeholders vs. team-only), and outcomes (backlog vs. process improvements).
Explain story points and why they're used over time-based estimates
Tests your grasp of relative vs. absolute estimation. Define story points as a relative measure of effort, complexity, and uncertainty. Explain they foster team consensus and provide a more stable velocity than time-based estimates.
Explain a backlog refinement meeting's purpose, participants, and outcomes
Tests understanding of a core Scrum ceremony. A good answer defines the goal (clarifying future work), names participants (Dev Team, PO), and lists outcomes (estimated stories).
Why is tracking team velocity as a KPI dysfunctional?
Tests if you know velocity is for planning, not performance. Explain it's easily gamed and measures output, not outcome. Propose metrics focused on value delivery and process improvement like cycle time.
Feature Teams vs. Component Teams: Pros and Cons
This tests your grasp of how team structure affects value delivery. A great answer defines feature (vertical slice, end-to-end) and component (horizontal, specialized) teams, then contrasts their trade-offs: speed vs. deep expertise.
How can developers support the Product Owner in backlog refinement?
Tests your proactivity and partnership beyond just executing tasks. A great answer covers proactive technical analysis, suggesting ways to split stories for incremental value, and helping the PO quantify impact.
How can a SAFe rule hinder agility, and how would you mitigate it?
Tests your ability to pragmatically adapt process. First, name a specific SAFe rule and a scenario where it fails. Then, propose a mitigation that still achieves the rule's original goal, like alignment. A red flag is just complaining about bureaucracy.
Estimating large, cross-team initiatives in PI Planning
Tests your ability to facilitate collaborative estimation. Break the initiative into features for teams to estimate, then use an ART board to map dependencies. A red flag is providing a single, top-down number without team input.
Technical Prerequisites for LeSS Feature Teams
This tests your grasp of the engineering practices that enable agile scaling. A great answer covers continuous integration for shared ownership, robust test automation, and a loosely coupled architecture. A red flag is focusing only on Scrum ceremonies.
Purpose of a Shared Definition of Done for Multiple Teams
This tests your ability to maintain quality and transparency across multiple teams. Explain that a shared Definition of Done ensures a consistent quality standard for a usable, integrated Increment, impacting testing by requiring integration and end-to-end…
What is a Scrum of Scrums and what's shared there?
This tests your understanding of scaling Agile. A good answer defines it as a coordination meeting for multiple teams, focusing on sharing inter-team blockers, dependencies, and integration points, not just status.
CFD 'Code Review' band is widening. What does it mean?
This tests your ability to interpret a CFD and propose actions. A widening 'Code Review' band means work enters faster than it leaves. Diagnose the bottleneck (e.g., review quality, reviewer availability), then propose solutions.
Investigating Variable Sprint Velocity
This tests your ability to diagnose issues by connecting process metrics to technical health. A great answer hypothesizes technical causes (e.g., tech debt, flaky tests), identifies specific data for validation (e.g., cycle time, build logs), and avoids…
