Four stages or challenges for the development of a new business;
- Customer validation – is there really an audience, who are willing to pay?
- Operational validation – can you deliver the product or service necessary to satisfy that customer?
- Financial validation – can your business make money providing the service or selling the products to the customer?
- Self-sustainability – can the business innovate and change in line with the customer and markets needs?
