The Task Analysis Inventory: The task analysis inventroy is a questionnaire or survey that includes a listing of tasks (100 or more is not unusual) for which respondents make some form of judgment. Usually these judgments are ratings given by respondents using a task rating scale, such as frequency of tak performance.
Becuase many different tasks exist in any job, this type of job analysis questionnaire is typically directed toward only one job or a class of very similar jobs. Most often, the inventory is intended for use by incumbents. Nevertheless, supervisors and observers can complete it - assuming they are knowledgeable about the job being studied.
Historically, the method has been widely used in military settings, in particular by the US Airforce. Although the origin of task inventories may be traced to the military, their use for selection purposes by both public and private employers has grown substantially. One important reason for the increasing use of these inventories is that many employers have adopted a content validation strategy for selection measures for which the inventories are particularly helpful.
