A method of identifying problems in a speech recognition application is provided and includes the step of obtaining a speech application call log containing log data on question-answer (QA) states and transitions. Then, in accordance with the method, for each of a multiple transitions between states, a parameter is generated which is indicative of a gain in a success rate of the speech recognition application if all calls passing through the transition passed instead through other transitions. In exemplary embodiments, the parameter is an Arc Cut Gain in Success Rate (ACGSR) parameter. Methods of generating the ACGSR, as well as systems and tools for aiding developers are also disclosed.
