Pugh Chart

Here's our pugh chart - it shows the different options we weighed when deciding how to approach our problem. It's gone through several different versions so far, this is the latest one (it was updated by Yi and Mike). We weighted the different design parameters differently to indicate the importance we think they have to our device design.

The design parameters that we gave the most weight were long-term effectiveness, reliability, accuracy, economy, maintainability, and of course, safety. Long-term effectiveness includes the device's ability to address immediate and long-term needs and its ability to do so in a efficient manner, both of which we consider crucial. Reliability, accuracy, and safety are all important in ensuring that our device will actually help our patients monitor their blood glucose levels in a way that is useful to them and that the device itself cannot cause them any further harm. Economy and maintainability are important because if these aspects are lacking, then even a "perfect" device will never make a difference to patients in this developing setting because it will remain inaccessible or unuseable to them.
