This document discusses training needs analysis (TNA), which is the first step in instructional systems design (ISD) and the ADDIE model. It describes the three components of a TNA: job-task analysis, learner analysis, and context analysis. A job-task analysis involves breaking down tasks into steps and sub-tasks, and identifying the knowledge and skills required to complete the tasks. A learner analysis gathers information about learners' characteristics, knowledge, skills, and other attributes in order to design effective instruction. Context analysis examines environmental factors like resources, equipment, and budgets that may impact training design. The results of a TNA can be presented visually using a value-add training framework
