Carlisle Companies refers to their approach as the Carlisle Operating System (COS). The sharp rise in US Output/Hr Index is a measure of this improvement which has been the result of Lean Mfg concepts gaining wider and wider acceptance. The rate of US Total Output/Hr has more than doubled since April 1995. It is likely that it may have even been responsible for companies finding themselves with excess labor in 2005-2007 as productivity soared and then found it necessary to shed employees in 2008-2009. But, the sharp recovery in production with fewer employees since June 2009, has impoved the US global trade position and I would expect it to continue. This should result in more jobs in the US in future months and years.
