My understanding of the scientific process is. Start: an idea.
If it progresses it becomes a hypothesis with ways of testing it being explored.
If it progresses and passes tests it may become a scientific theory which is not the same as a theory used in everyday speech which may just be an idea. Who decides if and when it becomes a scientific theory? Generally when enough scientists working in the area refer to it as a scientific theory. There are no set timetables - there will always be arguments and scepticism so if you are sceptical it is regarded as healthy but I don't believe that you should necessarily find agreement with your scepticism.
The scientific theory is constantly tested and if found wanting is either changed or abandoned, a process which happens. --- I don't think that the process is flawed, but the humans who use it, being human can be flawed.
