Results from Data Carrier Analysis for Circular Construction Supply Chains

This anonymized data is a result from an experiment testing three data carriers (QR Codes, NFC Chips, and Direct Product Marking) for Circular Construction Supply Chains. Using a quantitative experimental design, the study evaluates these technologies based on speed, SUS user experience, and error rates. The task was to use the data carriers on 12 components and count how many components were older than 25 years old. The participants were timed, any errors in the final result was counted, and they subsequently filled out a System User Scale for the data carrier used. There were three stated hypotheses explored: 1) Higher levels of data carrier device digitization are expected to lead to a decrease in reading time. 2) Higher levels of device digitization are anticipated to result in a decrease in the number of errors. 3) Higher levels of device digitization are anticipated to result in higher SUS scores. The findings reveal that the use of QR codes and NFC chips significantly improves efficiency and user satisfaction compared to DPM. The Location had no statistically significant impact on results, and there was no shown difference for the Errors.
