Why 6 Sigma quality is needed? Learn from example.

Suppose say you have a process and it is measured as 3.8-Sigma. Below are example from industry, how does it look like: 

  • EMAIL INDUSTRY: 20,000 lost articles of mail per hour
  • HEALTH INDUSTRY: Unsafe drinking water for almost 15 minutes each day
  • MEDICAL INDUSTRY: 5,000 incorrect surgical operations per week
  • AIRLINE INDUSTRY: Two short or long landings at most major airports each day
  • DRUG INDUSTRY: 200,000 wrong drug prescriptions each year

Now, say, you did  improvement  and had achieved 6 Sigma. So, how does it really make a difference from above? Check below same example:

  • EMAIL INDUSTRY: Seven articles lost per hour
  • HEALTH INDUSTRY: Unsafe drinking water one minute every seven months
  • MEDICAL INDUSTRY: 1.7 incorrect operations per week
  • AIRLINE INDUSTRY: One short or long landing every five years
  • DRUG INDUSTRY: 68 wrong drug prescriptions per year
