Reliability and validity of a survey for designing a global positioning system

An increasing trend of affordable GPS receivers has been released from military use to civilian use, especially in the automobile industry. In a competitive market, it is critical to launch a GPS product, which meets the needs of customers. However, there are limited resources of obtaining customer opinions' on future GPS products due to the fact that it is a relatively new technology for civilians.;The goal of this study is to design a GPS customer survey to capture the voice of customer to motivate strategic analysis on the future GPS market. 14 questionnaire items were designed to compose the GPS survey contents. The survey must have high instrument reliability, and evidence of content validity.;The results indicated the designed GPS survey demonstrated evidence of reliability and validity to support the designed GPS customer survey study is a feasible instrument method to reflect the voice of customer. Furthermore, an exploratory factor analysis (EFA) provided 36 a better factor analysis result reduction from 14 factors to 2 factors which provided evidence for further investigation in future.
