Backlog refinement meeting

This is a part of Sprint which takes no more that 10% of Sprint's time

Thank you.

Product Backlog Refinement is an ongoing activity, and unless it is being conducted at scale it is not a time-boxed event. However, there is nothing to stop teams from time-boxing each refinement session anyway. In general it is good practice to use time-boxing.

Thanks.

Hi all,
I'm new in PSM and have a naive question, plz help me to clarify if possible. Thanks

I have a concern, " no more that 10% of Sprint's time", does that mean that if a sprint 2 weeks (10 working days), we shouldn't spend more than 10% x 10 days = 1day for Refinement meeting?

Thanks,
Vinh

Keep in mind, the 10% is a guideline in the Scrum Guide:

"Refinement usually consumes no more than 10% of the capacity of the Development Team."

From my experience, refinement sessions usually consume 5-10% of the sprint length.

If your sprint length is 2 weeks, your team should be working with your product owner to refine future stories anywhere from 4-8 hours per sprint, split up among as many refinement sessions as needed.

Hi All,

I am new to Scrum as well and was a little confused by the response. Is backlog refinement albeit of future user stories etc) part of the previous sprint or is it a separate event outside of the sprint with a recommended guideline of not using more than 10% of dev team's bandwidth for this ?

Thanks,

It is a current sprint effort for the team and the Product Owner to groom stories for future sprints (meet Definition of Ready).

"is it a separate event outside of the sprint "
There is nothing outside of the Sprint.
A new sprint starts just right after the last one.

If this is the case, when does the refinement happens i.e Definition of Ready is met for the very first sprint? It would be inevitably outside first sprint if I am correct.

There are already several threads on this subject, the latest of which is below:

Hello I am New to Scrum 

Who are involved in Product Backlog Refinement Meetings ? 

background being that during backlog refinement work is sliced (comprehended correctly), estimated to make a story(s) ready to be picked for a sprint. So, typically product owner and team are involved and if required other stakeholders. Having stakeholders help in clarifying any assumptions/questions so as to keep getting traction on refinement without getting blocked by long discussions on a story.

Backlog Refinement is not a time-boxed event but it does not mean it cannot be time-boxed. The team just need to allocate enough time on backlog grooming over sprint so that backlog will be clean and ordered by your next sprint planning.
