A Value Platform Analysis Perspective on Customer Access Information Technology

Robert J. Kauffman, Laura Lally
1994 Decision Sciences  
The results indicate that there are a number of key features influencing ATM performance.  ...  Hypotheses regarding the likely impact of automated teller machine (ATM) location design choices and environmental features on ATM transactions are evaluated.  ...  The correlation between OTHERS-ON-US and US-ON-OTHERS is much higher (e.42, p=.001). This result suggests that customers select ATMs based upon the type of transaction they wish to perform.  ...
