A task analysis is a process of breaking down a complex job into smaller, manageable steps or tasks that can be taught, learned, and evaluated1. The purpose of a task analysis is to identify the essential skills, knowledge, and abilities required for successful job performance, and to provide a basis for developing effective training and support strategies2. Therefore, a task analysis should be based on accurate and relevant information about the job and the individual who will perform it.

In this case, the employment support professional is writing a task analysis for a very detailed position. Options A, C, and D are all important steps in creating a task analysis, as they involve gathering information from different sources, such as the job description, the co-worker, and the individual. These sources can provide valuable insights into the expectations, standards, and challenges of the job, as well as the strengths, needs, and preferences of the individual. Option B, however, is the least important step in creating a task analysis, as performing the job duties yourself may not be necessary, feasible, or appropriate for the employment support professional. Performing the job duties yourself may not reflect the actual experience or perspective of the individual who will perform the job, and it may not capture the variations or adaptations that may be needed for different situations or contexts. Therefore, option B is not a crucial step in creating a task analysis. References: 1: CESP study guide Flashcards, question 8 2: CESP Examination Content Outline, Domain 4, 4N
