I think I understand your question, correct me if I am wrong. In process means that the VO that has your file has opened your package and is currently reviewing paperwork, documents, medicals and police checks and decision made is on its way soon!
Decision made means after reviewing all of your paperwork, documents, police checks, medicals and their own back ground checks they have made a decision (as far as I am aware this is a very good sign your application is successful)
Application received means that the VO has your paperwork where it will enter a queue to be processed.
Application received is by far the longest process and can range from a month or so to a few months and in long visa offices it can be over a year (check VO processing times)
Hope this helps
