Optimal performance is a key requirement for today's mission-critical business applications, which have become more and more complex as trends like Service-Oriented Architectures (SOA) and Enterprise Application Integrations (EAI) become more prevalent. However, load testing solutions alone have failed to ensure that applications will meet their performance goals in time before deployment. A primary reason is that while load testing tools are useful at identifying performance bottlenecks, they often fail to guide their users in exactly how to resolve them. As a result, time is wasted in what might be called a "Blame game" between QA and system engineering about who is responsible to finally fix the issue, which results in excessive cost overruns and missed release schedules.
