This is a great TED talk by Dan Bricklin, the inventor of the electronic spreadsheet. The application he created – VisiCalc – is the original precursor to Excel, one of the easiest to use number-crunching tools when doing workforce analysis and just about everything else. He tells a great story of the disruption that his new tool caused its first audience, the MBA class he attended at Harvard, and the first conference where he revealed it.
This is a story of invention, so watch for key words like error, daydream, magic, imagine, prototype, feedback, find solutions, new capabilities, and marketing. This is a story of iterative design, where they figured out what they were creating part-way through the exploration.
