A resource breakdown structure, or RBS, is a list of resources needed to deliver a project. It comprises everything that costs money, including people, tools, materials, licenses, places, and time. Developing an RBS helps project or resource managers categorize available and required resources by function and type, minimizing risk and uncertainty and producing more successful outcomes.
Drawing up an RBS before working on a new project brings many benefits. Apart from clarifying what you’ll need and what you have, resource breakdown structures help to identify and group resources in a way that fosters the efficient implementation of resources throughout a project’s development cycle.
