Devise an outline, consistent with the scientific method, which interface researchers should follow to validate their designs.

1. First know the problem that needs interface. 2. Speak to and observe the people who were already working on the problem without the interface and know the thought how they want it to be 3. Develop a theoretical version and consult the people and make the changes if needed. 4. Make the model of the interface while using the fake data and take the opinion of the people if they are comfortable and satisfied with. 5. Connect the developed model to the actual data and see if it functions and send it to the users for testing. Look if any flaws went unnoticed. 6. Finally make it available to the users.
