Innovation — incremental and disruptive
Innovation — Incremental and Disruptive
This topic is assessed in IBDP Business Management at Higher Level (HL) only.
Not all innovation is alike. A business might improve the battery life of an existing product by 15% through engineering refinement, or it might introduce a product that makes the entire existing product category obsolete. These represent fundamentally different types of innovation — incremental and disruptive — with very different risk profiles, resource requirements, and competitive implications. Understanding the distinction, and the circumstances in which each is more appropriate, is essential for evaluating a business's innovation strategy.
Incremental innovation
Incremental innovation involves making continuous, small improvements to existing products, services, or processes — refining what already exists rather than replacing it with something fundamentally different. Each individual improvement is modest in scope: a 10% efficiency gain in a production process, a new colour option for an existing product, a software feature that makes an existing function faster. Accumulated over time, incremental improvements can generate significant competitive advantage — but the trajectory remains within the existing product paradigm.
Incremental innovation is associated with: the kaizen philosophy of continuous improvement (examined in the methods of lean production section); regular product line refreshes in consumer goods; and the ongoing software updates through which technology platforms improve their functionality. Most business R&D is incremental in nature.
Advantages: Lower risk — each improvement is small enough that failure has limited consequences; well-understood customer acceptance because the product remains recognisable; faster time-to-market (months, not years); lower investment per iteration; and predictable return on investment in established markets.
Limitations: Cannot fundamentally reposition a product or create a new market; competitors can match incremental improvements relatively quickly; may leave a business vulnerable to a disruptive competitor that renders the entire existing product obsolete.
Disruptive innovation
Disruptive innovation — a concept developed by Clayton Christensen — describes innovations that initially perform worse than established products on the dimensions that existing customers value, but that offer a different set of advantages (lower cost, greater simplicity, or new capabilities) that appeal to previously unserved or underserved customer segments. Over time, the disruptive product improves along the dimensions that mainstream customers care about, eventually displacing the established product entirely.
Classic examples: digital photography initially produced lower quality images than film but was cheaper and instant — it eventually displaced film photography entirely. Streaming video initially offered a much smaller library than DVD rental but was more convenient and cheaper — it eventually displaced the physical rental market. In each case, the disruptive innovation entered at the low or unserved end of the market and progressively moved upmarket as the technology improved.
The defining characteristic of disruptive innovation is not that it is technologically sophisticated — it is that it redefines the dimensions on which the market competes, making the previous incumbent's strengths less relevant whilst exploiting a dimension (cost, convenience, accessibility) where the incumbent is vulnerable.
Advantages: Can create entirely new markets or completely redefine existing ones; generates large, durable competitive advantages if the disruptive product becomes the new standard; often enables market entry against well-established incumbents who are slow to respond because the disruption initially targets segments they do not value.
Limitations: Very high risk — most disruptive innovation attempts fail, either because the technology does not mature sufficiently or because market adoption is slower than projected; requires sustained investment over long periods without guaranteed return; demands significant organisational capability and cultural tolerance for uncertainty; and incumbents, once they recognise the threat, can use their superior resources to accelerate their own response.
Meridian pursues both innovation types simultaneously across different parts of its business. Its predictive maintenance algorithm improvements — quarterly model updates that incrementally improve prediction accuracy from 82% to 84% to 86% — are incremental innovation: continuous refinement of an existing capability that improves competitive positioning without changing the product category. Its research team is separately investigating drone delivery integration for last-mile urban logistics — a genuinely disruptive concept that would redefine the cost structure and speed of urban parcel delivery, but one that requires regulatory approval, significant technology development, and a customer acceptance journey that may take five to ten years to complete. The incremental programme generates quarterly competitive gains with high predictability; the disruptive programme carries high execution risk over a long horizon but could create an entirely new competitive position if successful. Meridian's management allocates approximately 80% of the R&D budget to incremental improvement and 20% to disruptive exploration — a portfolio allocation that balances near-term competitive maintenance with long-term strategic optionality.
Key Takeaways
- Incremental innovation makes continuous small improvements to existing products and processes — lower risk, faster return, but cannot redefine the competitive landscape.
- Disruptive innovation redefines the dimensions on which a market competes, initially serving unserved segments before moving upmarket and displacing incumbents — high potential reward but very high risk and long time horizon.
- Most businesses pursue both: incremental innovation to maintain current competitive position, disruptive exploration for long-term strategic optionality.
- Disruptive innovations do not necessarily begin as technologically superior — they offer a different value proposition (cost, simplicity, accessibility) that appeals to segments incumbents underserve.
- Incumbents are systematically vulnerable to disruption because their resources and management focus are committed to serving existing customers on existing competitive dimensions — precisely the dimensions that disruptors avoid.
