  Governments in sub-Saharan Africa have implemented e-Government projects.
Actualizing the value propositions and sustaining such values are becoming
problematic. Some scanty studies on the value propositions of implemented
e-Government projects did not consider actualization of the values. Besides,
such studies lack theoretical underpinnings, the identification, and measure of
what constitutes actualized values. Neither did they capture what mechanisms
could sustain the actualized values nor the contextual conditions enabling its
sustainability. Consequently, using a concept-centric systematic review, we
identified the value proposition of such implemented projects. By drawing from
theories of affordance actualization, realist evaluation (RE) theory,
self-determination theory, and sustainability framework for e-Government
success. We conducted a RE of the implemented e-Government projects in Rwanda
using RE as a methodology in three phases. In phase one, we developed the
initial program theory (IPT), in phase two, we used contingent valuation as a
quantitative approach and realist interview as qualitative method to validate
the IPT. Lastly, in the third phase, we synthesized the results of the two
investigative case studies to develop the actualized values sustainability
framework. Such framework encapsulates, the actualized value propositions,
mechanisms and enabling conditions in interactions to sustain the value
propositions discovered in the e-Government investigative contexts.
