12. Key solution elements
- Design for tablets and computers
- Responsive web design
- JavaScript based front end, allows offline
- AtomFeed based integration
- Coarse grained APIs
- Product configuration handled by OpenMRS/
OpenERP. OpenELIS needs to be enhanced.

13. Bahmni modules UI design
- Responsive web design
- Touch screen (tablet) first mostly
- Registration module is data-entry intensive,
hence designed for computers only
