When you start a business there is a time period between having the idea and then actually being able to implement the idea. It is very rare that you are able to see someone that has an idea and can immediately begin with the business within the next few days. How long do you think is a sufficient time frame that you should be doing research on a business idea before starting to take it into reality? Typically my opinion would be around four to six month to ensure in depth research over a sufficient time frame.
