‘London's wobbly bridge: learning from failure’ considers examples of the ways in which much progress in science, engineering, and innovation is built upon failure. It is because of risks and uncertainties that there is so much failure in innovation, but failures also provide valuable opportunities for future improvements. Innovation encourages organizational and personal learning, but it requires strong leadership to outweigh the potential negative outcomes. There is a continuing debate on the impact of innovation on employment and its effect on the quantity and quality of jobs. Economic wealth depends upon improved productivity, and this is frequently driven by innovation. Innovation and improvements in technology and organization contribute to what is known as multi-factor productivity.
