A Business model is an organized way to lay out your assumptions about not only the key resources and key activities of your value chain, but also your value proposition, customer relationships, channels, customer segments, cost structures, and revenue streams — to see if you’ve missed anything important and to compare your model to others.
Remember: a good business model it's not a garantee of success, but it is a strategic choice you make. It is a way to summarize your hypotheses, puting the pieces together.
Guess less, research more! To build your business plan, ask potential users, purchasers, and partners for feedback on all elements of the business model, including product features, pricing, distribution channels, and affordable customer acquisition strategies; make test to validate your product...go to the market with pretotypes and prototypes till you arrives with a competitive product or service; be flexible with your strategy, including the feedback of your mentors and potencial clients!
