Only 2.4% compound annual growth rate for SC planning

Although the total market size for supply chain planning is already above 1 billion. But such low compounded annual growth rate indicates wave of SCM would be past soon.

The worldwide market for Supply Chain Planning is expected to grow at a
compounded annual growth rate (CAGR) of 2.4 percent over the next five
years.
The market was $1.05 billion in 2005 and is forecasted to be over
$1.18 billion
in 2010, according to a new ARC Advisory Group study, "Supply
Chain Planning
Worldwide Outlook: Market Forecast and Analysis Through
2010."

Nevertheless, I think the slow increase rate is due to lack of professionals. So companies cannot convert software to the profit.
