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.
