Workflow and Backlog/Sprint View in Jira

Hi Everyone,

I was wondering if people working with mature teams closely following Scrum and using Jira could share with me two things:

(a) what do your workflows look like for the various issue types?  Story, Task, Bug for example.  ie.  are they simple with only “open”, “in progress”, and “done”? or does your team have 5-10?

(b) does your team typically work from the backlog view where work items are listed horizontally, or from the sprint view where work is listed vertically, with each column containing work items in that state of the workflow?

Thank you,
