Final answer:
Two job analysis techniques are observation and interviews, which are pivotal for creating job specifications; reliability may vary based on the information source.
Step-by-step explanation:
Two job analysis techniques are observation and interviews. Observation involves watching someone proficient in a role to identify necessary skills, whereas interviews involve asking people in the role, as well as their peers and supervisors, to get a comprehensive understanding of the job's requirements. These techniques are critical to forming a base for job specifications and descriptions used to attract suitable candidates. However, the accuracy and reliability of a job analysis can depend on the nature and source of the job information. Research by Dierdorff & Wilson (2003) suggests that analyses based on incumbents' descriptions may be less reliable.
