Whitney Associates is one of the few companies that specialize in providing proactive performance assurance services for use in the development of large IT projects. Performance assurance helps ensure that the performance requirements (response times, throughput etc...) of a system are met cost-effectively. This helps guarantee satisfied customers and prevents costly overruns required to correct last-minute performance problems.

Performance assurance combines the disciplines of mathematical analysis, simulation and modeling, benchmarking and performance testing to provide an accurate, accountable means of keeping system design on the track to success.
