6. Infrastructure development:  RISA is involved in the development and deployment of ICT infrastructure in Rwanda. This includes the development of a national backbone network, the deployment of broadband infrastructure, and the establishment of data centers and cloud services.

7. Cashless Payment System: RISA works in partnership with various stakeholders, including banks, telecommunication companies, and payment service providers, to ensure the system's smooth functioning and adoption by the public.

8. ICT Sector Strategic Plan: RISA has been involved in the development of a national ICT Sector Strategic Plan 2018 - 2024, which outlines the government's vision for the use of ICTs in Rwanda.
