In project management, the acronym PIB stands for Project Initiation Brief. This document outlines the fundamental aspects of a project, including its objectives, scope, stakeholders, and preliminary requirements. The PIB serves as a foundational reference point, guiding the project's direction and parameters from the outset. By clearly defining expectations and responsibilities, it facilitates effective communication among team members and stakeholders. A well-structured PIB is vital for aligning project goals and ensuring successful project initiation and planning.
