Think about measuring innovation as you would an investment portfolio, where you are concerned with the total return rather than individual stocks, bonds, or mutual funds.
The key is not to measure each project individually and then declare victory or defeat, but to measure total investment over a period of time compared to total output.
This pools high- and low-risk projects and encourages people to take canny chances.
– A.G. Lafley (former CEO of Procter & Gamble)
