I usually see two job titles in the IT industry. My understanding of their most commonly accepted usage (simplified):

• Business Analyst: Main role is eliciting the users' needs
• Software Developer Main role is to design, build and test a software solution answering the needs

I'm wondering: "How we should call somebody whose role is to do both of the roles above?" Is this a common job title? And is trying to find people with these broadness of skills realistic, difficult?

EDIT: I'm specifically interested to name Lead Software Developers who have eventually learned and can apply techniques of Business Analysis.
