Which type of innovation emphasizes incremental improvements to sustain a product line and reduce risk?

• A. Incremental or sustaining innovation
• B. Radical or breakthrough innovation
• C. Disruptive across markets
• D. Reverse innovation

Answer: (A)

Incremental or sustaining innovation is about making small, continuous improvements to an existing product to keep it competitive and extend its life. This approach focuses on refining features, performance, reliability, or cost based on feedback from current customers, which helps sustain the product line while keeping risk low. Since it builds on familiar technology and markets, the investments are generally smaller, with more predictable returns and a quicker path to market, making it ideal for gradual optimization and ongoing revenue.

Radical or breakthrough innovation involves large, fundamental changes that create new capabilities or markets, but these carry much higher risk and uncertainty. Disruptive across markets describes innovations that change how customers buy or use products and can transform entire industries, often beyond merely updating an existing line. Reverse innovation refers to developing products in emerging markets and then spreading them to developed ones, which is a different strategic pattern than simply incremental improvements to sustain a current product.
