The dizzying change triggered by technology in organizations has made it necessary to make quick and accurate decision-making in a multi-actor environment. To implement these decisions as soon as possible, it is necessary to have a high degree of integration in all units of the organization. And the staff must perform the tasks expected of them without any misstep. This situation forces the organizational systems to become compatible with their elements. Traditional task analysis methods applied in strict hierarchical institutions are criticized for requiring intensive labor, budget, time, and resources. In this traditional task analysis, the collection of information in a long process and with a lot of effort, the necessity of collecting data from a representative sample and the limited use of the collected data have triggered the need for new analysis methods. In this study, the job analysis of vocational instructors in an in-service training institution with a strict hierarchical structure was performed with DACUM (Developing a Curriculum), known as the new generation competency-based job analysis method. As a result of an analysis that lasted only one and half day, the duties, tasks, knowledge, skills of the instructors, the behaviors expected of them, the equipment they use, future trends of their occupation were revealed. With the results obtained from this study, it has been determined which critical issues will be considered in the selection of qualified instructors for the institution and in the performance evaluations of the instructors.
