Hello - at the company we are using SCRUM to build web-sites. On the Sprint Planning Meetings we have an issue that when we discuss, estimate the User Stories some of the people are ?not able? to be active in the discussions/estimations.
I want to add that increment is build from two parts: frontend + backend and we have dedicated people for these parts of the system.
1. Is it normal that frontend guys are not active discussing/estimating backend part ?
2. Should we spread the knowledge of frontend over the backend guys.
Thanks for any support :)
