Table 3 Solution constraints and their rationale
Solution Constraint | Rationale |
|---|---|
The front-end application ran on a mobile phone | It is not feasible and affordable to use other computing devices such as personal computers. |
The front-end application had to work in offline mode | There is limited network connectivity in the selected target environment. |
The system used open-source technologies | This constraint was required to minimize the development costs of the system. |
The system should also be publicly available as an open-source product | The system is not developed for profit. Rather it is to be used by the regional health Office as well as other interested parties. |
