I really like how the *BABOK® v3 has redefined Business Analysis from the previous v2 version.
v3: The practice of enabling change in the context of an enterprise by defining needs and recommending solutions that deliver value to stakeholders.
v2: Set of tasks and techniques used to work as a liaison among stakeholders in order to understand the structure, policies, and operations of an organization, and to recommend solutions that enable the organization to achieve its goals.
Note the change in the work from gathering and relaying information as a liaison to enabling change in an organization.
Why do I like this?
