Definition of Ready (DOR):
DOR refers to the Definition of Ready in Agile. In the Agile Scrum framework, the Definition of Ready describes the requirements that must be met in order for a story to move from the backlog to development. In keeping with agile tradition, Ready is often defined as a story that can be acted on immediately.
Furthermore, the Definition of Ready follow these factors that are commonly referred to as the “INVEST criteria” and they provide us with a good Definition of Ready for (PBI) Product Backlog Items. Therefore, a good Development Team will work with the Product Owner to ensure that a standard like this is followed by actively participating in Product Backlog refinement.
A good DOR consists INVEST matrix account to define a user story. According to scrum.org “INVEST” stands for:
- I (Independent). The PBI should be self-contained and it should be possible to bring it into progress without a dependency upon another PBI or an external resource.
- N (Negotiable). A good PBI should leave room for discussion regarding its optimal implementation.
- V (Valuable). The value a PBI delivers to stakeholders should be clear.
- E (Estimable). A PBI must have a size relative to other PBIs.
- S (Small). PBIs should be small enough to estimate with reasonable accuracy and to plan into a time-box such as a Sprint.
- T (Testable). Each PBI should have clear acceptance criteria which allow its satisfaction to be tested.
Benefits of DOR
- Limits the risk of misunderstanding
- Avoids beginning to work on unready issues
- No waste of time with a discussion about the work process
- It also helps in the efficient communication between members
- Definition of Ready helps in minimizing the rework of a user story.
Example of DOR
Definition of Done (DOD):
DOD refers to the Definition of Done in agile. It is a small document that represents a checklist of the activities or features that must be completed before referring to a story as “DONE”. This checklist helps the team track all the steps to be completed to consider a story to be done.
Let’s look at different types of DoD, according to Scrum Alliance, there are three main types:
- Definition of Done for a feature ( user story or product backlog item)
- Definition of Done for a sprint (collection of features developed within a sprint)
- Definition of Done for a release (potentially shippable state)
Benefits of DOD
- DOD helps to improve product quality
- Help to forecast how many stories to take during sprint planning
- It helps to deliver the product on time
- Reduce wastage of time
- It also limits the risk of misunderstanding

Summary
The Scrum Guide does not define the Definition of Ready, but the User stories or the Acceptance Criteria are defined in the scrum. Definition of Ready is part of the backlog refining process. The Definition of Done on the other hand is an agreed-upon set of items that must be completed before a project or user story can be considered complete. It acts as an official gate separating things from being “in progress” to “done.”
