What are the advantages and disadvantages of conventional job analysis methods?

Conventional job analysis methods, such as interviews and questionnaires, provide detailed insights into job responsibilities and required skills, ensuring that roles are well-defined and aligned with organizational needs. However, they can be time-consuming, costly, and may suffer from biases if the input is limited to a small group of employees. Additionally, these methods may not effectively capture dynamic or evolving job roles, leading to outdated or incomplete analyses. Overall, while they offer valuable data, they require careful implementation to mitigate their drawbacks.
