Business Model Innovation for Sustainability: Towards a Unified Perspective for Creation of Sustainable Business Models

Advances in neurobiology have demonstrated that the brain is so sensitive to external experiences that it can be rewired through exposure to cultural influences. Experiments have shown that in some people, parts of the brain light up only when they are presented with an image of Bill Clinton. In others, it's Jennifer Aniston. Or Halle Berry. What other stimuli could rewire the brain? Is there a Boeing brain? A Goldman Sachs brain? No one really knows yet, says Medina, a developmental molecular biologist, who has spent much of his career exploring the mysteries of neuroscience with laypeople. As tempting as it is to try to translate the growing advances to the workplace, he warns, it's just too early to tell how the revolution in neurobiology is going to affect the way executives run their organizations. "If we understood how the brain knew how to pick up a glass of water and drink it, that would represent a major achievement," he says. Still, neuroscientists are learning much that can be put to practical use. For instance, exercise is good for the brain, and long-term stress is harmful, inevitably hurting productivity in the workplace. Stressed people don't do math very well, they don't process language very efficiently, and their ability to remember--in both the short and long terms--declines. In fact, the brain wasn't built to remember with anything like analytic precision and shouldn't be counted on to do so. True memory is a very rare thing on this planet, Medina says. That's because the brain isn't really interested in reality; it's interested in survival. What's more, and contrary to what many twentieth-century educators believed, the brain can keep learning at any age. "We are lifelong learners," Medina says. That's very good news indeed."

"Business model" was one of the great buzz-words of the Internet boom. A company didn't need a strategy, a special competence, or even any customers--all it needed was a Web-based business model that promised wild profits in some distant, ill-defined future. Many people--investors, entrepreneurs, and executives alike--fell for the fantasy and got burned. And as the inevitable counterreaction played out, the concept of the business model fell out of fashion nearly as quickly as the .com appendage itself. That's a shame. As Joan Magretta explains, a good business model remains essential to every successful organization, whether it's a new venture or an established player. To help managers apply the concept successfully, she defines what a business model is and how it complements a smart competitive strategy. Business models are, at heart, stories that explain how enterprises work. Like a good story, a robust business model contains precisely delineated characters, plausible motivations, and a plot that turns on an insight about value. It answers certain questions: Who is the customer? How do we make money? What underlying economic logic explains how we can deliver value to customers at an appropriate cost? Every viable organization is built on a sound business model, but a business model isn't a strategy, even though many people use the terms interchangeably. Business models describe, as a system, how the pieces of a business fit together. But they don't factor in one critical dimension of performance: competition. That's the job of strategy. Illustrated with examples from companies like American Express, EuroDisney, WalMart, and Dell Computer, this article clarifies the concepts of business models and strategy, which are fundamental to every company's performance.
