Which method of Job Analysis requires the job incumbent to maintain a systematic chronological logbook or journal detailing their daily tasks, duties, and time spent on each activity?

The Employee Log / Self-Recording Diary Method is a primary job analysis technique where current employees (job incumbents) maintain a detailed, step-by-step written record or logbook of all duties, tasks, and routines performed throughout their workday, along with the approximate time dedicated to each. Key Advantage: It provides a comprehensive picture of complex, long-cycle, or non-routine jobs (such as managerial or technical positions) where direct observation by an analyst would be difficult or time-consuming. Limitation: It relies heavily on the worker's diligence, honesty, and subjective reporting, which can lead to exaggeration or memory recall errors.
