Re: [scrumdevelopment] Re: What does Jeff Sutherland mean by READY?
- For what it's worth, I like to have teams do enough story level
estimates for the upcoming couple sprints at least. (Some may feel a
need to estimate even more of the backlog stories, and that's ok if not
taken to extreme & turned into BDUF.)
But these are just the story points estimates that you do quickly, using
planning poker. It typically takes around 5 minutes per story. Then at
the sprint planning meeting, we break those into tasks that are small
enough for us to see movement every day or so. In other words, break
stories into tasks of 8 hours or less. No big deal if some are bigger
but they shouldn't be bigger than 2 days.
By doing it this way, the product owner & stakeholders have enough
future work "priced" to enable them to be deciding what they really want
the team to do next. Without story point estimates on the stories, they
are prioritizing with key info missing. That's going to force them to
revisit a lot of their thinking.
