Frugal innovations or frugal products are catching up technologically to serve the needs of humankind. Their features including minimal material consumption, affordability and good functionality make them green from the point of view of sustainable development. However, their no-frills structure typically also necessitates application of rigorous procedures for their design. This chapter stresses on the need for stringent quality control after creating a frugal product out of the rigorous frugal-design process. The quality checks would aid in developing long-term competitive solutions for frugal products while the control would facilitate adherence to stringent product specifications. Accordingly, this chapter stresses the breaking up of quality check into two parts for confirming both the rigor of design procedures and also performance of resulting frugal products. © 2021, Springer Nature Switzerland AG.
