Scrum is an agile project management framework that is used for product development processes. In this Scrum framework, there are two key concepts DoD and the DoR, that define the state of a task or user story. Both these terms look similar, but are quite different.
DOR means Definition of Ready is a checklist or set of criteria that a team uses to determine if a user story or task is ready for development. On the other hand, DoD means Definition of Done is a checklist of the work to be done before declaring the work completed.
In this article we are going to look in depth about What Is DoD and DoR in Scrum? and what are the key differences between them to understand conceptually.
What is the Definition of Ready?
A “ Definition of Ready “ (DoR) is a checklist used in Agile software development and other project management methodologies to define what conditions/criteria must meet before a task or user story can be started.
It ensures that all necessary inputs and information are available before work begins. It helps to improve efficiency and eliminate delays in work delivery. CSPO training equips Product Owners to refine prioritized lists against DoR and validate deliverables against DoD, ensuring quality and readiness.
This DOR helps scrum team members understand what needs to be done to ensure that all the inputs are available, exceptions are arranged, and probability of task completion as per higher acceptance criteria.
What is the Definition of Done?
The Definition of Done (DoD) is a shared checklist that confirms when a task in the Scrum environment is truly complete. It ensures all team members agree on what “done” means, preventing misunderstandings.
A user story or task might only be “Done” after writing code, coding comments, unit testing, integration testing, release notes, design documents, code review, and deployment. Without clear DoD, work might be considered finished too early, leading to bugs or incomplete features. CSM certification training equips scrum masters to facilitate and coach teams on DoD adoption.
By following the DoD, teams maintain quality, consistency, and transparency, ensuring every deliverable meets the required standards before going forward.
Key Features of the Definition of Done (DoD):
Definition of done (DoD) is important to a highly functioning scrum team.
Why makes it important:
- A Checklist of Valuable Activities: Ensure all the necessary steps are completed to deliver quality software.
- Primary Reporting Mechanism: Help team members to track progress.
- Informed by Reality: DoD is based on true capabilities and project needs.
- Not static: It’s not a constant checklist, changes based on project requirements.
- Auditable Checklist: It Provides clear, measurable standard to verify completed work
Key Differences Between DoD and DoR:
| Feature | Definition of Done (DoD) | Definition of Ready (DoR) |
| Purpose | Ensures a work item is fully complete and deliverable. | Ensures a work item is ready to be taken into a sprint. |
| When Used | At the end of a task/user story. | Before a task/user story enters a sprint. |
| Focus | Quality and completeness of deliverables. | Clarity, feasibility, and readiness for development. |
| Created By | Development Team (with Scrum Master & PO input). | Product Owner & Development Team collaboration. |
| Checklist Items | Testing, code review, documentation, etc. | Clear acceptance criteria, dependencies resolved, estimated. |
| Impact if Not Met | Work is not considered done; cannot be released. | Work is not started; sent back for Backlog refinement. |
| Changes Over Time | Evolves as the team improves (e.g., automation). | Adjusts based on feedback & project needs. |
| Audience | Developers, testers, stakeholders. | Product Owner, Scrum Master, Developers. |
| Example Criteria | ✓Code Quality:
● Peer-reviewed and approved ● Follows style guidelines ● Refactored
✓ Testing ● Unit tests passed ● Integration tests complete ● UI tests verified
✓ Documentation ● Code comments updated ● Technical docs revised ● User manuals modified
✓ Deployment ● Builds successfully ● Deployed to staging ● Smoke tests passed
✓ Business Acceptance ● Product Owner verified functionality ● Matches acceptance criteria ● Peer demo conducted. |
● User story has clear acceptance criteria.
● Dependencies identified & resolved. ● Business value defined. ● Technical feasibility confirmed. ● Estimated by the dev team. ● UX/UI designs approved ● No open questions/blockers. ● Compliance/legal checks done (if needed). ● Broken down into small, testable pieces. ● Aligns with sprint goals. |
| Agility Role | Ensures deliverables meet quality standards. | Prevents wasted effort on unclear requirements. |
Conclusion:
As a summary, the Definition of Done (DoD) is core commitment, to make sure a project or product meets desired quality standards before every release. Teams use it to verify completion during development, planning, and reviews. On the other side, Definition of Ready (DoR) is optional, not like a mandate thing as DoD, helps assess if checklists (Prioritized backlog items) are well-prepared before entering the sprint.
So finally, Together, they improve efficiency; DoR prevents unclear work from starting, on other side DoD guarantees deliverables meet expectations. By using both, teams improve collaboration, reduce rework, and deliver higher-value increments consistently.
