According to prior research, many researchers were used to the
SERVQUAL scales made by Parasuraman et al. However, this research
has a different viewpoint compared to the research of Parasuraman et al.
and the viewpoint of this research is to measure transportation services
from the viewpoint of service providers. This research grouped the
measuring factors into three sub-dimensions. The factors were used in
various research projects because of clearance and exclusion. The factors
used in this research were developed to measure customer service from the
viewpoint of service providers. Therefore, this research uses measuring
factors of customer service produced by Stank et al.41) on the basis of the
factors developed by Parasuraman et al. Customer service is of importance
because of verifying advantages and disadvantages of service estimated by
service providers, whereas customers estimate services provided by
service providers and this is connected with SERVQUAL. Therefore, this
research uses customer service produced by Stank et al. to test
transportation services of the forwarders.
