Most of the vendors cut their teeth in the client/server arena but there are some new faces...

Segue Software Inc., Lexington, Mass., offers solutions designed to mimic real-world scenarios. Scenario testing is the process of creating a series of scenarios that model an event occurring as an effect of three factors: the rate of change (includes content and functionality change introduced by sudden competitive pressures); the mix of platforms, tiers, and technologies an application must traverse; and the volume and fluctuation of user activity. Segue's LiveQuality solution simulates this real-world situation in a safe test environment, providing insight on potential problems before the system goes live.
