Business model innovation is usually more powerful than technical innovation; it is more disruptive and harder to copy than technical innovation. And yet, so many companies are focused on technical innovation to compete.
Consider Airbnb. What makes them so successful is not a technical advantage, but a business model advantage that provides them near-zero marginal cost. For a traditional hotel chain to increase its capacity, it needs to build more physical space at significant cost. Instead of shouldering that setup cost, Airbnb can add another room to its inventory at almost no cost by enabling people to share their existing houses. That is a business model innovation. Furthermore, it is extremely difficult for the traditional hotel chain to switch its business model to match Airbnb's.
The same is true in Open Source software. While it is true that Open Source often produces technically superior software, its real power may be its business model innovation: co-creation. Open Source software like Drupal or Linux is a co-created product; thousands of contributors build and enhance Drupal and everyone benefits from that. A large Open Source community produces vastly more software than a proprietary competitor, and shares in the production and go-to-market costs. It disrupts proprietary software companies where the roles of production and consumption are discrete and the production and go-to-market costs are high. While established companies can copy key technical innovations, it is extremely difficult to switch a proprietary business model to an Open Source business model. It affects how they build their software, how they monetize the software, how they sell and market their software, their cost structure, and more. Proprietary software companies will lose against thriving Open Source communities. I don't see how companies like HP, Oracle and SAP could change their business model while living quarter to quarter in the public markets; changing their business model would take many years and could disrupt their revenues.
Take Amazon Web Services (AWS), one of the most disruptive developments in the IT world the past decade. While AWS' offerings are rich and often ahead of the competition, the biggest reason for the company's success is its business model. Amazon not only offers consumption-based pricing ('pay as you consume' vs 'pay as you configure'), it's also comfortable operating a low-margin business. Almost 10 years after AWS launched, at a time that vast amounts of computing are moving into the cloud, HP, Oracle and SAP still don't have competitive cloud businesses. While each of these companies could easily close technical gaps, they have been unable to disrupt their existing business models.
If you're in a startup, innovating on a business model is easier than if you're in a large company. In fact, an innovative business model is the best weapon you have against large incumbents. Technical innovation may give you a 6 to 18 month competitive advantage, but the advantage from business model innovation can be many years. Too many startups focus on building or acquiring innovative or proprietary technology in order to win in the market. While there is usually some technical innovation around the edges, it is business model innovation that makes a successful, long-standing organization -- it tends to be a lot harder to copy than technical innovation.
