Information quality deficiencies in delivery schedules and their impact on production scheduling
Artikel i vetenskaplig tidskrift, 2017
The purpose of this paper is to explore how di erent delivery schedule characteristics a ect the quality of shared delivery schedule information and, in turn, how de ciencies in quality a ect a supplier’s production scheduling process. It describes a case study conducted in the Swedish automotive industry involving a supplier that operates as the rst-, second- and third-tier supplier to an original equipment manufacturer. The study reveals how four delivery schedule characteristics – namely, receiving frequency, planning period, frozen period and demand variation – create information quality (IQ) de ciencies in ve dimensions of IQ: completeness, conciseness, reliability, timeliness and credibility. At the same time, it demonstrates how such de ciencies a ect the supplier’s production scheduling process by requiring additional rescheduling, reworking and follow-up activities as well as additional capacity problems, safety time, safety stock and backlogs. In e ect, the paper extends previous IQ-related research by considering IQ in delivery schedules.
