A job/task analysis is (JTA) is a very close look at a job, portion of a job, or concept job in order to identify the tasks and associated knowledge, skills and abilities (KSAs) required to competently perform the job.  A JTA is the foundation for the development of a certification program or a certificate program.  Only after the KSAs have been identified can a certification body or educational program determine how to measure competence of the KSAs or how to teach the KSAs.  There are multiple methods for conducting a JTA including using focus groups, structured interviews, job shadowing and observations, and surveying practitioners.  When conducting a JTA as the basis for a certification program, the method used is not as important as making sure the right subject-matter-experts (SMEs) participate in the process.
