Innovation has transformed the world from the dark ages to today. The story of Thomas Edison shows how innovation can create immense value and success. Edison invented the phonograph and lightbulb after thousands of failed experiments. Successful companies continuously innovate in products, services, marketing and other areas. For example, Salesforce innovated the software-as-a-service model and Apple transformed the music industry with the iPod. Dell innovated supply chain management to build custom computers. Innovation requires questioning assumptions, observing customers, networking, experimenting and making connections. Companies can develop an innovation culture by encouraging these skills and sharing knowledge across the organization.
