Facilitation & Collaboration Skills
A facilitator is someone who helps a group of people understand their common objectives and assists them to plan to achieve them without taking a particular position in the discussion. As a facilitator, the BA brings the team together divergent business stakeholders and helps them speak with a single voice so the project team are not confused by contradictory and conflicting perspectives. The BA aims to listen to and understand feedback from all stakeholders and use this feedback to drive changes to the requirements and priorities of the project.
Collaboration is working together to achieve a goal. The BA brings together the development team and business stakeholders to discuss the requirements and collaborate on a common understanding of the requirement, the detail of the requirement, and specifics around the solution
