A construction firm won a bid to build a cable bridge. With a project charter and assigned project manager, the manager is creating the WBS. To what level should the project be decomposed?

The Work Breakdown Structure (WBS) decomposes project work into smaller, manageable components. The correct level of decomposition is the work package, which is the lowest level where cost and duration can be reliably estimated and managed. This allows for effective control and monitoring of the project. Decomposing to a level based on quality or safety, while important project considerations, isn't the primary driver for WBS decomposition. Similarly, decomposing to a specific schedule level (like "level four") is arbitrary and doesn't align with the WBS's purpose of defining the scope of work.
