PPA Desktop
PPA Desktop is an open-source desktop tool that helps teams run Patient Pathway Analysis workflows locally, from raw uploads and mapping to generated outputs.
Challenge
- PPA work often depends on fragmented data, technical analysts, and multiple tools, which slows down delivery and complicates handover.
- The product needed strong privacy guarantees because users work with sensitive country and facility data.
Approach
- Structured the workflow around the real steps teams follow: upload, validate, map, and generate outputs.
- Used local Docker-based execution to keep data processing on-device while still packaging a guided end-to-end experience.
Outcomes
- Made a specialist workflow more repeatable, portable, and easier to use across teams.
- Improved data privacy by avoiding dependency on hosted infrastructure for the core workflow.
