The work on the service delivery in the context of one-shop government architecture is far from being mature. Although, the understanding on various levels of complexity of e-government service delivery has been addressed; many extant versions of the service delivery architectures themselves are dated and do not reflect the potential contribution of new technologies. In this work-in-progress paper, we report ongoing work and propose an updated service delivery architecture comprising five distinct layers. The proposed architecture addresses some important challenges, and suggests areas for future research, as outlined in the paper.
