title: Cognitive ergonomics of a mail order filling company: Part 2--influence of shelf coding and address information on acquisition time.
abstract: This is the second part of a study on a mail order picking task. In the first part of the study, recognition time was addressed by varying colour, position and highlighting cues in a computer-simulated version of the picking task. This study addresses the product acquisition time. Shelf coding and continuous presentation of the address information were varied in a factorial experiment in which 14 subjects (seven experts and seven novices) had participated. Experts were slower but more accurate than the novices. Continuous display of address information appears to be a good training aid for implementing new shelf coding systems, and for new operators. Shelf coding effect appears to disappear with practice. A summary of the recommendations is given.
