This study is to discuss an empirical case study on performance analysis in X-company and link to the process of developing competency models. The purpose of performance analysis is to correctly identify the problem in order to select, implement, and evaluate appropriate interventions for accomplishing positive performance results and outcomes. We suggest that the utilization of competency be a critical research agenda for improving performance because competency identification is to explain key requirements for a job category such as activities, tasks, setting, and tools. Even though competency modeling is time-consuming and expensive work, competency model can be a helpful intervention tool improving human performance. In this sense, a competency model can be a useful tool. Keywords : human performance technology, performance analysis, competency, competency modeling
