The strong improvements in information and communication systems as well as better transshipment technologies provide the platform for more efficient transport within interorganizational transport chains. Nevertheless these technologies do not automatically optimize systems based on routines and behavioral patterns, established over the last decades. Logisticians - in theory and practice - have to consider the field of behavioral science to describe and analyse transport problems regarding to involved actors' strategic behavior and social embeddedness, too. The objective of this paper is to illustrate behavioral aspects of supposed technical problems in interorganizational transport chains. Therefore, this paper analyses behavioral routines and governance structures in the interorganizational maritime transport chain using a case study, dealing with the generation and circulation of transport information at the earliest point available, so called "estimated time of arrival" (ETA).
