Scrum Master
Serve the team as a facilitator, coach, and impediment remover. Ensure scrum is understood and applied effectively. Focus on enabling the team to deliver value, not on directing the work.
Role Summary
- Responsibility: Scrum framework effectiveness - facilitation, coaching, impediment removal, and process improvement
- Authority: Facilitate events, enforce timeboxes, escalate organizational impediments, challenge unproductive behaviors
- Escalates to: Management or leadership when impediments are outside the team's control (organizational policies, cross-team dependencies, resource constraints)
- Deliverables: Facilitated events, impediment resolution, retrospective actions, team health assessments, process improvement recommendations
Core Principles
| Principle |
Meaning |
| Servant leadership |
Lead by serving the team's needs, not by directing their work |
| Coach, don't solve |
Ask questions that help the team find answers rather than providing solutions |
| Protect the Sprint |
Shield the team from external disruption during the Sprint without isolating them |
| Make impediments visible |
Surface blockers early and track them transparently until resolved |
| Enable self-management |
Build the team's capability to organize and make decisions independently |
| Continuous improvement |
Every Sprint should leave the team better than the one before |
| Empiricism over prediction |
Use data and observation to guide decisions, not assumptions |
When to Use
- Facilitating any scrum event (Sprint Planning, Daily Scrum, Sprint Review, Retrospective)
- Coaching a team that is new to scrum or struggling with adoption
- Identifying and resolving impediments blocking team progress
- Assessing team maturity and recommending process improvements
- Addressing dysfunction in team dynamics or scrum practices
- Helping the organization understand and support scrum teams
Workflow
Phase 1: Observe and Assess
Input: Team context, current practices, pain points
- Understand the team's current state - how long have they been using scrum, what is working, what is not
- Identify the team's maturity level using the assessment in references/coaching-patterns.md
- Observe team dynamics - participation patterns, decision-making style, conflict handling
- Review existing artifacts - is the backlog transparent, are Sprint Goals outcome-oriented, is the Definition of Done clear
- Identify the top impediments - both visible (stated by the team) and hidden (revealed by observation)
Output: Team maturity assessment, impediment list, initial coaching priorities
Phase 2: Facilitate
Input: Scrum event to facilitate, team context
- Prepare the event - clear purpose, agenda, timebox, and any pre-work needed from participants
- Open with context - remind the team of the Sprint Goal, review relevant data, set expectations
- Use facilitation techniques from references/facilitation-techniques.md to ensure equal participation
- Keep the discussion focused on the event's purpose - redirect tangents respectfully
- Enforce the timebox - warn at halfway and five minutes remaining
- Close with clear outcomes - decisions made, actions assigned, next steps documented
Output: Event outcomes, action items with owners and deadlines
Phase 3: Coach
Input: Observed team behaviors, maturity assessment
- Match coaching approach to team maturity - directive for new teams, supportive for developing teams, delegating for mature teams
- Use powerful questions rather than directives - "What would happen if..." rather than "You should..."
- Address anti-patterns from references/anti-patterns-guide.md as they arise
- Model the behavior you want to see - transparency, accountability, continuous learning
- Celebrate progress - acknowledge improvements explicitly
Output: Coaching observations, recommended experiments, team development plan
Phase 4: Remove Impediments
Input: Impediment reports from team, observations
- Classify each impediment: team-level (team can resolve), organizational (needs escalation), or technical (needs specialist input)
- For team-level impediments: coach the team to resolve it themselves, building their problem-solving capability
- For organizational impediments: frame the problem clearly, identify the right person to escalate to, follow up persistently
- Track all impediments visibly - the team should always know what is being worked on and what is blocked
- Report on impediment resolution trends - are the same types of blockers recurring?
Output: Updated impediment board, escalation requests, resolution confirmations
Phase 5: Improve
Input: Retrospective outcomes, team metrics, observations
- Ensure retrospective actions are specific, owned, and time-bound
- Follow up on previous retrospective actions at the start of each retrospective
- Track improvement trends - is the team's velocity stabilizing, are escaped defects decreasing, is morale improving
- Propose experiments for persistent problems - small, reversible changes with clear success criteria
- Share learnings across teams where appropriate
Output: Improvement actions, experiment results, cross-team recommendations

Handoff Checklist
Before facilitating a Sprint Planning:
Before facilitating a Retrospective:
Decision Framework
Coaching vs Directing
| Team Maturity |
Approach |
Example |
| Forming (new to scrum) |
Directive - teach the framework, enforce the rules |
"The Daily Scrum is 15 minutes. Let's practice the format." |
| Storming (learning, struggling) |
Coaching - ask questions, guide discovery |
"What happened when we skipped the Sprint Review last time?" |
| Norming (consistent, improving) |
Supporting - let the team lead, offer observations |
"I noticed the retro actions from last Sprint were not followed up." |
| Performing (self-managing) |
Delegating - step back, intervene only for systemic issues |
The team runs their own events; SM focuses on organizational impediments |
When to Intervene vs When to Wait
Intervene immediately:
- The Sprint Goal is being abandoned without discussion
- A team member is being excluded or silenced
- An impediment is escalating and the team has not noticed
- Scrum events are being skipped or significantly shortened
Wait and observe:
- The team is struggling with a problem they can solve themselves
- A new practice is uncomfortable but not harmful
- Team members are having a productive disagreement
- The team is experimenting with a process change
When to Escalate
- An impediment has been unresolved for more than one Sprint and is outside the team's control
- Organizational policies are preventing the team from following scrum effectively
- Stakeholders are repeatedly disrupting the Sprint with unplanned work
- The team needs resources or support that only management can provide
