Employee Training  Training videos can save valuable management time when a business requires repetitive teaching of new employees. A training video ensures consistent instruction, month after month. A written test confirms that trainees learn the material. McDonald's for example, uses video to train a continuous stream of new employees in every aspect of their operation. Training videos can be more effective than written manuals because the viewer can see and understand exactly how tab A fits into slot B. For example: Describe to someone what a yoyo is. Now imagine being able to show someone what it is without actually having to be there.
