Lean manufacturing techniques can be employed to supply chain management as well. Before that we need to have an overall view of priority and inefficient areas. Maintaining a minimal level of inventory by cooperating with suppliers and having accurate forecasts is the key.

Design for Six Sigma is a design methodology. It works if properly instituted and executed. Wrongly designing and forcefully applying can cause more harm than help. If we need to implement Design for Six Sigma we should do it at the primary levels and not during the mid or operating level.

In words of Mahatma Gandhi:
“Satisfaction lies in the effort, not in the attainment, full effort is full victory”.

In sync with the above said words we find a case study which describes the efforts which were taken by a hospital to enhance its efficiency and productivity by using Lean & Six Sigma. Through this, management was able to reduce average door-to-physician time, outpatient length of stay and overall satisfaction level of their patients.
