Need to have a system where the user get one and one question (in total 100 or more)to tick off Yes/No.
A number of known causes of the problems /diseases are described with corresponding symptoms.
Each symptom must be able to "weight" (give a numerical degree of relevance or importance) the symptoms related to the various diseases: For instance "Coughing at least 10 times an hour during the last 14 days" will be weighted as 10 for Tuberculosis, but only 2 for flue.
The setup must be ready made and installed on a server. The back-end user must be able to insert new symptoms and diseases, and give them a weigh.
The front end users must be able to tick of all the questions, and be given a list of the 20 most likely causes of the problem / disease.
This is not a 5 day project. But itis your choice. If you want, we can apply the Agile methodology and techniques from Extreme Programming.
We will keep in touch, I will show you how things evolve.
I will be available 10 hours / day.
Thanks!
