''The WBS provides a hierarchical structure that outlines the activities'' this statement is wrong about the work breakdown structure (WBS)
<u>Explanation:</u>
As clear from the name, work breakdown structure which is mostly used to manage projects of an organisation, is a way in which the project that is to be completed is divided into smaller components among the people of the team working on that project according to their capabilities to bring more efficiency in the project and to finish the project faster. It helps to identify the obstacles and risks related to the project in a better way.
