Recently I was skimming through a magazine which was an issue on e-retail start ups in India.
If you look at all of them, you can easily notice that their business models are built around social media and group buy. These two are popular phenomena that rule the e-commerce market.
Another observation is that they are very focused. They target a sect of people rather than targeting all in the internet buyers. I think that is the way to find a niche in a crowded market. Nevertheless, Indian internet market has a huge potential to grow.
Often, you may have to convey your new idea to stakeholders to implement them. It is a tricky task as you have get them to visualize what you dreamed in your mind.
First go is to prepare a vision statement. You vision statement should vividly describe what your idea is and it must appeal to the stakeholders implicit or explicit interests. Imagine that you have just 2 mins time to express your idea.
