While recognition accuracy is an important part of an OCR product, it is not the only concern. Recognition products are productivity tools - their objective is to make people more productive by reducing the time it takes to translate printed text or image files into editable text. Recognition accuracy is only a part of a total productivity solution. The measure of a truly useful OCR product is not just its recognition ability, but whether, and to what extent, it improves your productivity.
The essential tasks for an OCR product are those that allow you to work most efficiently, i.e., to maximize your throughput. Users of current OCR products know that you can waste a considerable amount of time getting to the point where your electronic document is ready to use. Among the most common time sinks are: manually defining page layout, assigning text, graphic and/or numeric zones, proofing recognition errors and reformatting documents after export. A product that minimizes or eliminates the additional time it takes to perform these tasks is the product that maximizes throughput.
