About @RISK

Welcome to @RISK, the revolutionary software system for the analysis of business and technical situations impacted by risk! The techniques of risk analysis have long been recognized as powerful tools to help decision makers successfully manage situations subject to uncertainty. Their use has been limited because they have been expensive, cumbersome to use, and computationally intensive. However, the growing use of computers in business and science has offered the promise that these techniques can be commonly available to all decision makers.

That promise has been realized with @RISK (pronounced "at risk"), a system that brings risk analysis techniques to the industry-standard spreadsheet application, Microsoft Excel. With @RISK and Excel, any risky situation can be modeled, from business to science to engineering. Each user is the best judge of their analysis requirements, and @RISK - combined with the modeling capabilities of Excel - allows for the design of models that best satisfy those requirements. Any time a decision or analysis involves uncertainty, @RISK can be used to gain insight into how the future might unfold.
