In the Work Breakdown Structure (WBS), larger tasks are typically referred to as "Phases." The WBS is a hierarchical decomposition of the total scope of work to be carried out by the project team to accomplish the project objectives and create the required deliverables. At the highest level, the work is often divided into phases, which are large, main portions of the project. These phases are then broken down into smaller tasks and subtasks, providing a detailed roadmap of the project work.
