    Inventory Accuracy: People, Processes, and Technology is currently out of Print.  A New Edition will be available soon. 


A comprehensive treatment of  Inventory Accuracy and Cycle Counting in distribution, fulfillment, and manufacturing environments.

Inventory accuracy starts with an understanding of the conditions under which errors occur and ends with error-resistant processes, intelligent use of technology, a well-trained and highly motivated workforce, and an ongoing process of continuous improvement. In between, there’s cycle counting, root cause analysis, process evaluation, user interface design, procedures, employee training, accountability, control methods, process checks, audits, exception reporting, transaction techniques, measurement, counting methods, bar codes, RF systems, speech-based technology, light systems, and software.

Inventory Accuracy: People, Processes, & Technology covers all of these topics and more in a comprehensive treatment of the subject of inventory accuracy in distribution, fulfillment, and manufacturing environments. In addition to documenting the standard tools and techniques used to achieve accuracy, the author provides insights as to why many of the standard solutions don’t provide the best results and offers alternative methods. The focus on practical solutions that take into account the sometimes-conflicting priorities that affect accuracy, results in an approach that not only looks good on paper, but more importantly, works in the real world.
