It is unfortunate that a lot of us are trained to chase a perfect answer as opposed to designing something that is less than perfect, useful, and inspirational to future generations to build on it. We look at technology in a small snapshot and think what it can do for me and others now. We don't think of technology disruption as a continuum to solve a series of problems. Internet started that way and the first set of start-ups failed because they defined the problem too narrowly. The companies that succeeded such as Google, Amazon, eBay etc. saw Internet as a long term trend and didn't think of it in a small snapshot. Cloud and Big Data are the same. Everyday I see problems being narrowly defined as if this is just a fad and companies want to capitalize on it before it disappears.
Build that first element table and give others an imagination to extend it. As an entrepreneur you were not the first and you are not going to be the last trying to solve this problem.
