Final answer:
Helen is using a worker-oriented approach to job analysis, focusing on the personal characteristics like knowledge, skills, abilities, and other traits required for an employee to perform the job of an executive assistant successfully.
Step-by-step explanation:
Helen is conducting a job analysis for the role of an executive assistant and is focusing on the characteristics required for the employee to be successful in the position. The approach that best describes Helen's method is the worker-oriented approach. This approach is concerned with describing the knowledge, skills, abilities, and other characteristics (KSAOs) that are necessary for a worker to perform the job effectively.
It is less about the specific tasks and more about the attributes and qualities a potential employee should possess to carry out those tasks well.
In contrast, a task-oriented approach would focus on the specific duties involved in the job.
It is also worth noting that industrial-organizational (I-O) psychology plays a significant role in this area of business by helping to match individuals' characteristics with the job's requirements, which is particularly relevant in the context of the worker-oriented approach to job analysis.
