General principles when thinking about roles

"What is the right thing to do?" NOT "Is this part of my job?"

Reference: John Shook on responsibility-focus versus authority-focus; see Managing to Learn.

"If we fail, then I fail"

Less people (via combined roles) means less communication overhead

Reference: Steve McConnell on team size and communication paths

Prefer T-shaped people

References: Specialistion is for insects; Scott Ambler on generalising specialists; Tim Brown on T-shaped people

Adjust the roles to fit the people NOT adjust the people to fit the roles
