¶ … Sigma has often become the associated trademark for all processes involving a managerial approach towards increasing the efficiency of an organization. More and more, Six Sigma has become a tool that management can use in the aviation industry for the same purpose of streamlining operations and activity in order to drive a reduction in costs and an increased efficiency, with the final objective of maximizing profits. At the same time, Six Sigma proposes the increase in quality of the products delivered to the final consumer.
There are several distinct areas of the aviation industry that the Six Sigma methodology can target. On one hand, there is the turnaround time that airplanes spend in repair. There are two costs that such an activity incurs. The first is the cost of the actual repair. It is obvious that if the repair time is longer, then the costs are also increased due to more labor that needs to be paid, plus auxiliary fixed costs, such as the cost of the hangar where the plane is kept during the repair time.
Another important cost that needs to be considered is the cost of opportunity: the planes that are in a process of repair are not flying, which means that they are not making money for the company, which is not able to sell tickets on those planes. Every additional day that the plane spends in a hangar for repair is equivalent to millions of dollars lost in opportunity costs.
It is now clear why Collins Aviation Services introduced Six Sigma to decrease the turnaround time on servicing a standard avionics box from 22 days (of which only six were spent on actual repair), to just over four days
. The implementation of Six Sigma was not done only within Collins Aviation Services, but also with subcontractors, in order to obtain a maximized efficiency and improved quality throughout...

Army has been modernizing its logistics function for the past half century, and a wide range of legacy systems remain in place.
