Background knowledge to deeply understand ‘The Innovator’s Dilemma: When New Technologies Cause Great Firms to Fail’ by Clayton Christensen
Disruptive Innovation
At the core of Christensen’s book is the concept of “disruptive innovation.” This refers to a specific type of innovation that initially targets a niche market with a less sophisticated product or service. Over time, these disruptive innovations improve in performance and eventually displace established market leaders. It’s crucial to understand that disruptive innovations are not necessarily “better” in a conventional sense at the outset. They often have lower performance in areas valued by the mainstream market, but offer other advantages such as affordability, simplicity, or convenience.
A key distinction is made between disruptive innovations and “sustaining innovations.” Sustaining innovations improve existing products along dimensions valued by mainstream customers. They make good products better in the eyes of established market segments. This focus on existing customers, while seemingly rational, can blindside companies to the threat of disruptive innovations emerging from below.
Value Networks
Christensen introduces the concept of “value networks” to explain why established firms struggle to respond to disruptive innovations. A value network is the context within which a firm identifies and responds to customer needs, solves problems, procures inputs, reacts to competitors, and strives for profit. Each value network has its own unique “rank ordering” of product attributes based on customer priorities and profit margins.
Established firms excel within their existing value networks. They are optimized to listen to their best customers and deliver products with high profit margins. However, this very expertise can become a liability when confronted with a disruptive innovation that initially appeals to a different value network with different priorities.
Resource Allocation
The resource allocation processes within established firms are heavily influenced by the demands of their existing customers and the potential for high profit margins. This creates a natural bias towards sustaining innovations that serve the needs of the mainstream market and generate immediate returns.
Disruptive innovations, on the other hand, often promise lower profit margins and target smaller, less attractive markets in their early stages. This makes it difficult for established firms to justify allocating resources towards them, especially when facing pressure to maintain short-term profitability.
Technology S-Curves
The concept of technology S-curves helps explain the performance trajectory of innovations over time. Initially, a new technology experiences slow progress as it struggles to find its footing. Then, a period of rapid improvement follows as the technology matures and gains wider adoption. Finally, the rate of improvement slows down as the technology approaches its physical limits.
Disruptive innovations often emerge based on new technology S-curves that initially underperform compared to established technologies. However, these new technologies can eventually surpass the performance of incumbent technologies, catching established firms off guard.
Organizational Structure and Culture
The organizational structure and culture of established firms are often optimized for efficiency and execution within their existing value networks. This can create inertia and resistance to change when confronted with disruptive innovations that require different capabilities and approaches.
Established firms often have well-defined processes, hierarchical decision-making structures, and a culture that emphasizes incremental improvement rather than radical change. These characteristics can hinder their ability to recognize, embrace, and effectively respond to disruptive threats.
Examples of Disruptive Innovations
Throughout the book, Christensen provides numerous examples of disruptive innovations across various industries, including:
* **Disk drives:** The transition from large, high-capacity mainframe disk drives to smaller, lower-capacity disk drives for personal computers.
* **Excavating equipment:** The shift from cable-operated mechanical excavators to hydraulic excavators.
* **Steel minimills:** The rise of minimills producing low-cost rebar steel, eventually displacing integrated steel mills.
These examples illustrate the common patterns of disruptive innovation, showing how seemingly insignificant entrants can ultimately topple industry giants. By understanding the characteristics of disruptive innovations and the challenges they pose to established firms, readers can gain a deeper appreciation of the arguments presented in “The Innovator’s Dilemma.”
