Yes if the task is complex if the task is done infrequently if the information changes often if the consequences of mistakes are high if training funds are limited. No if use could damage your credibility if speed is critical if the situation is unpredictable if a high level of problem solving is needed if employees are not motivated to look up information. Simply put, a job aid is nothing more than a place to store information that will help you do a particular task. It might be a chart showing which gages to calibrate on which dates, a list of steps for creating a control chart, or a manual to help you troubleshoot problems with a machine. Even if you're not familiar with the term, if you've ever used a phone book, a recipe, or a road map, you've used a job aid.
Training is about putting things into long-term memory.
Important, but expensive. Job aids are about creating a rich environment into which people can dip. Job aids are like cheat sheets. They let you use a piece of information, perform an activity, or make a decision based on knowledge that you have not committed to memory. When employees don't have to memorize the many details of their daily tasks, not only do they make fewer mistakes, but training time and expenses are also reduced.
