Lean Six Sigma

Marine Depot Maintenance Command (MDMC) is further developing its implementation of Lean Six Sigma (LSS). The MDMC has being using various Lean techniques since 2002, and the Marine Depot Maintenance Command wants to develop its LSS program and use it to continually improve it processes.

Concepts of Lean
Goal is to accelerate the speed of any process by reducing all forms of waste
Focuses on process speed/velocity 
Provides tools for analyzing process flow and delay times at each activity 
Focuses on separating "value added" and "non value added" work
Provides tools to eliminate the causes of "non value added" work 
Provides methods to measure process complexity and methods to simplify it
If we are doing something because “it’s just the way we do things” then it is probably waste
Examples of waste or “non value added” work: defects, inventory, overproduction, wait time, motion, transportation, and processing waste.

Concepts Six Sigma

Recognize opportunities and eliminate defects as defined by the customer
Variation should be reduced since it hinders our ability to meet cost, schedule, and quality requirements
Decisions should be made based on data 
Includes a set of quality tools to solve problems and analyze data
Provides a structured manor that helps aid in getting results

A Six Sigma quality level means there is less than 3.4 defects per million opportunities
