6.4 Definition of Done

Introduction

Definition of Done (DoD) is one of the most important concepts in Scrum. It defines the quality standards and conditions that must be satisfied before a Product Backlog item or Increment is considered complete.

The Definition of Done ensures transparency, consistency, and quality across the Scrum Team.

Without a clear Definition of Done, teams may misunderstand what “completed work” actually means.

What is Definition of Done?

Definition of Done is a formal checklist of criteria that determines when work is fully completed and ready for delivery.

A Product Backlog item is considered “Done” only when it meets all agreed quality standards.

Purpose of Definition of Done

The Definition of Done helps the Scrum Team:

• Maintain product quality
• Ensure transparency
• Create shared understanding of completion
• Reduce incomplete work
• Support potentially releasable Increment creation

Why Definition of Done is Important

Different people may have different interpretations of “completed work.”

For example:

• A developer may think coding is enough
• A tester may require testing completion
• A business stakeholder may expect deployment readiness

The Definition of Done removes confusion by establishing common completion standards.

Characteristics of Good Definition of Done

Characteristic	Description
Clear	Easy for everyone to understand
Measurable	Completion criteria can be verified
Consistent	Applied uniformly across work items
Practical	Achievable within sprint boundaries
Quality-Focused	Ensures product quality standards

Typical Definition of Done Criteria

A Definition of Done may include:

• Code completed
• Code reviewed
• Unit testing completed
• Integration testing completed
• No critical defects
• Documentation updated
• Feature deployed to test environment
• Acceptance criteria satisfied

Example of Definition of Done

Definition of Done Checklist
Code written and reviewed
All unit tests passed
Integration testing completed
No high-priority defects remaining
Documentation updated
Acceptance criteria met
Product Owner accepted functionality

Definition of Done vs Acceptance Criteria

Aspect	Definition of Done	Acceptance Criteria
Purpose	Defines completion standards	Defines feature requirements
Scope	Applies to all backlog items	Specific to one backlog item
Focus	Quality and completion	Functional behavior
Created By	Scrum Team	Usually Product Owner

Definition of Done and Increment

The Increment is considered complete only when it meets the Definition of Done.

If work does not meet DoD:

• It cannot be released
• It should not be demonstrated as completed work
• It usually returns to Product Backlog

Who Creates the Definition of Done?

The Scrum Team collaboratively creates the Definition of Done.

This usually involves:

• Developers defining technical standards
• Product Owner clarifying business expectations
• Scrum Master ensuring Scrum practices are followed

Evolution of Definition of Done

The Definition of Done is not fixed forever.

As the Scrum Team matures, the DoD may evolve to include:

• Higher quality standards
• Improved automation
• Security validation
• Performance testing

Benefits of Definition of Done

Benefit	Description
Improved Quality	Ensures consistent quality standards
Higher Transparency	Clear understanding of completion
Reduced Rework	Prevents incomplete deliveries
Better Collaboration	Shared understanding within team
Reliable Increment	Supports releasable product increments
Improved Customer Satisfaction	Higher product reliability

Role of Developers in Definition of Done

Developers:

• Follow quality standards
• Ensure technical completion
• Perform testing and reviews
• Maintain product integrity

Role of Product Owner in Definition of Done

The Product Owner:

• Clarifies business expectations
• Ensures acceptance criteria are satisfied
• Supports quality expectations

Role of Scrum Master in Definition of Done

The Scrum Master:

• Helps team understand DoD importance
• Encourages Scrum transparency
• Supports continuous improvement of DoD

Definition of Done in Different Teams

Different Scrum Teams may have different Definition of Done criteria depending on:

• Industry requirements
• Product complexity
• Technical standards
• Compliance requirements

Example

A banking application may require:

• Security testing
• Compliance validation
• Audit documentation

A startup MVP product may use a simpler DoD initially.

Common Challenges Related to Definition of Done

Challenge	Description
Unclear DoD	Completion standards poorly defined
Ignoring DoD	Team skips quality checks
Too Weak DoD	Low-quality standards
Too Complex DoD	Unrealistic completion requirements
Inconsistent Application	Different interpretation by team members

Best Practices for Effective Definition of Done

• Keep DoD clear and visible
• Apply DoD consistently
• Include quality standards
• Review DoD regularly
• Improve DoD continuously
• Ensure team agreement

Common Mistakes Related to Definition of Done

• Confusing DoD with Acceptance Criteria
• Skipping testing activities
• Declaring incomplete work as done
• Ignoring technical debt
• Using vague completion standards

Real-Life Example

Example:

A Scrum Team building an online banking system defines the following Definition of Done:

• Code completed
• Peer review completed
• Automated tests passed
• Security testing completed
• No critical defects
• Deployment successful in test environment

Only after satisfying all conditions can the work be considered complete.

Importance of Definition of Done in Scrum

Definition of Done is important because it:

• Ensures product quality
• Supports transparency
• Reduces misunderstandings
• Improves team discipline
• Enables reliable product delivery

Conclusion

Definition of Done is a critical Scrum concept that establishes clear quality and completion standards for the Scrum Team.

A strong Definition of Done helps teams deliver high-quality, reliable, and potentially releasable product increments consistently while improving transparency, collaboration, and customer satisfaction.
