Human factor analysis of error detection and correction in hand-knotted carpet production process

Purpose - The paper aims to discuss error detection and correction in Kashmiri carpet weaving (KCW), mediated by cryptographic code, Talim which is held to guarantee accurate information transference from designing to weaving, even after hundred years. Yet, carpets often show errors on completion. Design/methodology/approach - Human factors analysis revealed error emergence, detection and correction in this practice whose task domains are distributed over large geographies (from in-premises to several kilometers) and timescales (from days to decades). Using prospective observation method, production process of two research carpets from their design, coding and weaving was observed while noting the errors made, identified and corrected by actors in each phase. Findings - The errors were found to emerge, identified and corrected during different phases of designing, coding and weaving while giving rise to fresh errors in each phase, due to actors' normal work routines. Originality/value - In view of this, usual branding of "weaver-error" behind flawed carpet turns out to be misplaced value judgment passed in hindsight.
