The document discusses the difference between definition of ready (DoR) and refinement for product backlog items (PBIs). It states that DoR establishes the basic requirements for a PBI based on discussions between the development team and product owner, but that requirements can never be fully understood. Refinement is then described as the ongoing process of clarifying PBIs by asking more questions, putting them in application flows, checking mockups, and using the INVEST tool to ensure PBIs are independent, negotiable, valuable, estimable, small, and testable. The goal of DoR and refinement is to develop a shared understanding of value which empowers the team to make decisions and commit to delivering PBIs.

1. Definition
of Ready
vs.
Refinement
What/When/Why?

2. When you
think, PBI is
ready…

4. Troy Magennis:
’When we asked someone to estimate how long it
will take to develop a feature or project they think
about how long it would take hands-on, with
PERFECT hand-off between teams and other staff
with the specialist skillset. This never happens.’

5. What does it
mean that PBI
is ready?

6. PBI is ready
when…
there is nothing to
add to
requirements.

7. Ziv’s law:
’Requirements
never be
completely
understood.’

9. Advise #1:
Don’t forget to ask
another question

10. Advise #2:
If you have asked
all questions, ask
another

11. Advise 3#:
Put the PBI into
app flow, to check
understanding

12. Advise #4:
Ask more
questions about
PBI in the flow

13. Advise #5:
Check on mockups,
if you didn’t forget
about anything

14. Do you think,
you know
everything?

16. Ziv’s law:
’Requirements
never be
completely
understood.’

17. You have DoR –
the BASIS to start
PBI development

18. What DoR really
is?
It’s a list of specific reqirements
details, established by dev team
with PO

19. Dev team is ready
for next step –
Refinement

20. Refinement is
a process of
taking care of
Product Backlog

21. Helping
tool?
INVEST

22. I – independant
N – negotiable
V – valuable
E – estimable
S – small
T – tastable

23. Refinement flow

24. Why do we create
PBIs according to
DoR and refine
them?
Because of a sense of the value.

25. When there is a sense of the value, team is:
• self-organizing rather than role- or title-based
• empowered to make decisions
• ready to solve any problem
• committed to team success vs. success at any cost
• ready to own its decisions and commitments
• consensus-driven
