<![CDATA[Work effectiveness is a key indicator of organizational sustainability and competitiveness, including in a limited partnership such as CV Wijaya Karya. Employees' ability to carry out operational tasks accurately, quickly, and according to standards depends heavily on their knowledge, skills, and work attitudes, which companies commonly develop through operational training. This study aims to examine the role of operational training in improving work effectiveness at CV Wijaya Karya and to identify its supporting and inhibiting factors. A descriptive qualitative approach was used. Data were collected through observation, in-depth interviews with management, the person in charge of training, and operational employees, as well as documentation. Informants were selected purposively, and data validity was tested through source and technique triangulation. Data were analyzed through data reduction, data display, and conclusion drawing. The findings show that operational training plays an important role in improving employees' understanding of work procedures, strengthening technical skills, reducing work errors, and making task completion smoother. This role becomes stronger when training combines explanation with hands-on practice and is followed by mentoring from experienced employees. The main obstacles are limited time and budget, heavy workloads, and training evaluation that still needs to be more structured. Operational training designed from a needs analysis and evaluated continuously can therefore serve as an effective strategy to improve work effectiveness. The study recommends periodic training programs, on-the-job mentoring, and structured evaluation.]]>
