The Rice scale is a project management tool that is used to help prioritize and assess the risk of a project. The scale is named after its creator, Roger C. Rice, and is also sometimes referred to as the Rice matrix.
The scale is used by identifying the three elements of a project: time, cost, and scope. Each element is then given a risk rating of low, medium, or high. The ratings are then used to create a overall picture of the project's risk.
The Rice scale is a helpful tool for project managers as it can help them identify and assess the risks associated with a project. It can also be used to help prioritize projects.
