The bad news is: “the money companies spend on R&D is producing fewer and fewer results,” according to Anne Marie Knott, Olin strategy professor, and author of the just-published book How Innovation Really Works.

In an article published on the Harvard Business Review website this week, Knott says, “My research shows the returns to companies’ R&D spending have declined 65% over the past three decades.” This decline begs the question and title of Knott’s article, “Is R&D Getting Harder, or Are Companies Just Getting Worse At It?”

Her research finds that companies are getting worse at R&D, but there’s a silver lining:

“It appears the decline in companies’ (and the economy’s) ability to drive growth from R&D stems from the fact that companies have gotten worse at innovation, rather than because innovation has gotten harder. This is great news, because the problem of companies getting worse is fixable, whereas the problem of innovation getting harder isn’t. The challenge, of course, is knowing what to fix and how to fix it.”
