Collaboration is now considered as a strategic advantage for enhancing effectiveness in Inter-Organisational Information System (IOIS) implementation, particularly in electronic government (e-government). As governments strive to improve their service delivery systems with constraint resources, IOIS was seen as the key factor for efficacy. Findings in this study revealed that the rhetoric and the reality of IOIS implementation were misaligned. Social and human factors were revealed as pertinent for this disparity and good governance was seen as the redeeming factor for IOIS implementation. Understanding these factors is critical in improving the probability of success in future IOIS implementation.
