There's no PM present in the Scrum daily. In fact, there's no PM in Scrum.

Jumping between different stories before finishing them is fine in solo projects, but if you're working with others, it means more code conflicts. That said, it is absolutely possible to work on multiple stories in Scrum.

I work Business Intelligence (BI) using SQL and a reporting tool of choice. There are times when I just cannot write another peace of SQL. I can tell what I am churning out is long winded and likely to be slow. There are always other tasks such as setting up stylesheets, setting my templates, distribution lists for reports and so on. The problem I have is I don't know when I will be tired, typical issue is always the data quality that results in complex SQL.
