49899Re: Having the Product Owner in team Estimation Meetings
- Jan 20, 2011Lang,
Ron is absolutely correct. Your last two scenarios are similar examples of the PO using an estimate to validate understanding, not influence the estimate. It may seem like splitting hairs, but it is an important distinction.
The PO is making sure there is a common understanding of the story, and increasing or decreasing the scope accordingly based on the estimation. The estimate for the work needed is up to the people delivering the increment.
