This Paper attempts to advance the study of training evaluation methodology, particularly concerned with executive development programme. The intent of the paper is to present a specific methodology for evaluating training function by way of conceptualising various training issues in the form of a process model. The traditional evaluation models designed by several researchers are criticized as being content influential and oriented towards individual programmes . While considering training function as a broader system, it is conceived that such system consists of five interdependent and process influential subsystems, namely evaluation system, influencing system, participant system, measurement system and output system. It is argued that any evaluation task that is directed on a training function should make concerted efforts towards evaluation of effectiveness of each individual subsystem and the factors which influences the effectiveness of other subsystems.
