Inside the Risk Gateway

The three parts of risk analysis

When and where will the next major flood occur? Will project bids come in under the government estimate? Will a built structure live up to its strength? How many work-related injuries can we expect on the job?

No matter where you work or what you are working on in the Corps, you face questions like these every day for which there are no easy answers. The reality is that we do not and cannot know the answers to many of the questions we run into during the performance of our jobs. What we can do, however, is to understand and manage the risks created by these uncertainties.

Risk analysis is the responsibility of every Corps employee. It is an effective way of thinking about and organizing to solve problems on the job and to address uncertainty.

This web site is your gateway to understanding the Corps model for risk analysis including, assessing, managing and communicating risk. We invite you to start by taking the one-hour online training course and then to explore other parts of the site for additional information, guidance, applications and other resources.
