Work Breakdown Structure
A Work Breakdown Structure (WBS) is a way to organize project tasks into smaller, more manageable pieces - think of it like a detailed to-do list for projects. It's similar to breaking down a big recipe into all its preparation steps. Project managers use this tool to map out everything that needs to be done in a project, making it easier to assign work, track progress, and estimate costs. You might also see it called a "project breakdown" or "task hierarchy." It's a fundamental project planning tool used across many industries, especially in business transformation and change management projects.
