What industry sectors had the greatest changes in inventory levels?

The chart below, created by SCDigest from data in the latest CFO magazine/REL annual working capital report, shows the industries that had the greatest changes in average Days Inventory Outstanding (DIO) from 2006-07. As we note in a most extensive analysis, a decrease in DIO is in general a good thing, and an increase a not so good thing. (See Digging Through the Inventory Numbers.)

Industry sectors not listed in the chart had modest changes in DIO, in the range of +/- 2%.
