Business Analysis

Provide an example of a project where a Business Analyst was not the member of the team. What happened? In your opinion, how could this outcome have changed if there was a Business Analysis on the team?

In your opinion, when should a Business Analyst be introduced into the project? When a request comes from a stakeholder? What team members should talk to the stakeholder about those requirements?

When does a Business Analyst need to define functional, non-functional, and transitional requirements?
