For which part of an initiative is the business analyst (BA) responsible?

A Business Analyst (BA) is primarily responsible for bridging the gap between business needs and technological solutions. They play a pivotal role in defining the solution approach, which includes understanding and interpreting both the business and technical aspects of a project. This involves identifying, analyzing, and documenting business requirements, and ensuring that the proposed solutions meet these requirements. BAs are not typically responsible for authorizing projects, approving execution plans, or accepting risk mitigation plans, as these tasks are generally within the purview of project managers or other stakeholders.
