"many people live in the idea of the idea rather than make it life."

The many factors that come into play to keep an idea afloat and to sustain for a long period of time are examined.

The first question to an idea is its Validity. Whether it’s survival is scenario and momentary, a temporary disturbance in supply of an existing product it is substituting. Whether the idea is really unique or a quality possessed by an existing product.  

Once the idea is proved valid, then the question arises if it is Notional or Real. Has the time and technology come for its implementation? Is there no easy way to implement it? Then one can patent the idea and sit on it to hatch one day.

The third comes Feasibility. Yes selling water in the desert is a brilliant idea. How are you going to do it?

Fourth comes Cost of Real World Implementation. An idea only makes what one is doing in one way better and easier. What is the cost of replacing the product that one is already using for whatever its shortfalls? What are the costs of identifying, reaching and supplying target audience, where all ever they are.

Fifth is Sustainability. This means the idea will have to improve and evolve with time to keep itself on the shelves. What is the future beyond the initial push and uptake. Lines of command and supply along with it and most importantly the thinking of the entrepreneur will have to grow as the idea grows.

Sixth is Funding. One must not even bother looking for funding if all the above criteria are unsatisfied.
