Wall Street Journal: A recent study by consultancy Booz & Co of 1000 of the world’s biggest research-and-development spenders found they are focusing on products with quick revenue opportunities, and killing less-promising projects. Nearly half of the respondents said they have tightened criteria for approving new projects.The survey found a shift away from basic research and toward applying existing technology to new products. That is a longstanding trend in corporate labs and has accelerated during the recession, says Booz partner Barry Jaruzelski.
