R&D at ELEKS focuses on developing expertise through internal projects rather than developing products, with the main goals being innovation and acting as a marketing tool. Three case studies are described: ADEL, an automatic differentiation library that was too niche; GGE, an interactive video that was innovative but not feasible; and a Tesla smartwatch app that was innovative but not realized. The document advocates letting geeks propose ideas but validating them against the market, keeping clients and goals in mind, and not fearing failure through experimentation.
