We reviewed documentation in the HCMC Data Warehouse and compiled findings, followed by the organization of a workshop with the HCMC Department of Information and Technology, DX Center, and other stakeholders to facilitate discussion. We developed a casebook to raise stakeholders’ awareness of possible solutions through open data access, with case studies and lessons learned discussed at the workshop. We created a replicable model for open data challenges and strengthened the pipeline for incubation activities.
