Frugal innovation involves designing simple, affordable products that achieve more with fewer resources. It is driven by the need to serve emerging markets and their growing middle classes. Local companies have advantages in frugal innovation due to cultural factors and market insights. However, multinationals are also pursuing frugal strategies through localized R&D, reverse engineering, and platform technologies. Success requires deep customer understanding, agile operations, and balancing local customization with global scale through innovation networks and shared resources. Frugal innovation benefits not just emerging markets but also addresses challenges in developed countries like cost reduction and environmental sustainability.
