So we had this idea to breakdown the application into the shopping isles style categories, were doctors could class questions as a certain type of category based on the diagnosis the doctor would've given. This would then allow patients access to FAQ type of information and get them to assess their symptoms from what was asked before. If unsure, they'd still be allowed to ask the question again and the doctors would refer then to a diagnosis already given if any.
We opted for changing the direction we were taking. We had initially thought that a social media type of approach would work for us. But we realised that that would be an issue down the line with people posing as imposter doctors and giving advice to patients that would either be incorrect and/or harmful. So we opted for changing it a bit by adding a mechanism to Validate and Authenticate doctors and their credentials on signup and the other user type would just be left as patient. Then we took away the ability for patients to comment on other patients' questions, while keeping only the readonly and liking (up voting) abilities.
This changed the whole course of the application and we had to think differently.
Managed to get the first prototype done, for illustration purposes, to see if the product we are building is what we were thinking about. So we had a few sessions during the development time to brainstorm and iron out some issues and realign ourselves.
