Harmonizing decentralized development of ICT solutions with centralized strategies, e.g., meant to favor reuse and optimization of resources, is a complex technical and organizational challenge. The problem, shared by virtually all the governments, is becoming a priority also for countries, such as Mozambique, that have started their ICT policy relatively recently and for which it is now evident that — if no particular attention is devoted to the interoperability of the solutions being developed — the result will rapidly become a patchwork of solutions incompatible with each other.
