Signs your dev team needs a Definition of Ready

What a Definition of Ready actually is

A Definition of Ready is a short, agreed checklist a ticket has to satisfy before a team pulls it into a sprint — clear acceptance criteria, dependencies identified, size roughly understood, no open questions for Product. It's the counterpart to a Definition of Done: DoD says when work is finished, DoR says when work is allowed to start.

Signs you're missing one

• Sprint planning regularly runs over its scheduled time because the team is still asking Product basic questions about tickets.
• Tickets get pulled into a sprint, then bounce back out mid-sprint once someone realises the requirements weren't actually clear.
• "Ready" means something different depending on who wrote the ticket.
• Developers start work, then discover a dependency or a design decision nobody had actually made yet.
• Estimates are consistently wrong in the same direction — usually because scope wasn't pinned down before sizing.

None of these are a sign your team isn't trying hard enough. They're the predictable result of nothing being agreed about what "ready to start" means.

What a good Definition of Ready includes

It doesn't need to be elaborate. A DoR that actually gets used is usually five items or fewer:

• Acceptance criteria written down, not just discussed verbally
• Dependencies on other teams or systems identified
• Rough size agreed by the people doing the work, not assigned by someone else
• No open questions for Product or a named stakeholder
• UI/UX or technical design decisions made where the ticket depends on them

How to introduce one without it becoming bureaucracy

The failure mode with a DoR is turning it into a rigid gate that just moves the bottleneck earlier in the process. A few things that keep it useful rather than performative:

• Start with three criteria, not ten. Add more only if a specific, repeated problem justifies it.
• Apply it at backlog refinement, not at the sprint planning meeting itself — by planning day it should already be a formality.
• Let the team that owns the DoR change it. If it's imposed top-down, it gets ignored top-down too.
• Review it every few sprints. A DoR that never changes usually isn't being enforced either.
