Just to keep your promises..
OR
Seriously to know about LEAN SIX SIGMA
WHAT IS LEAN SIX SIGMA ?It is a scientific methodology to
enhance your productivity by reducing waste and increasing your profit .
Made from two words-
i) LEAN

What is SIX SIGMA (6σ).. Credit for coining the term “Six Sigma” goes to a
Motorola engineer named Bill Smith.
Six Sigma is a business management strategy, originally developed by Motorola in 1986.
Six Sigma seeks to improve the quality of process outputs by identifying and removing the causes of defects (errors) and minimizing variability in manufacturing and business processes.
… contd
What is SIX SIGMA (6σ)… It uses a set of quality management methods,
including statistical methods, and creates a special infrastructure of people within the organization.
A six sigma process is one in which 99.99966% of the products manufactured are statistically expected to be free of defects (3.4 defects per million).
There are many cases where the data tends to be around a central value with no bias left or right, and it gets close to a "Normal Distribution" like this:

• Generally “Sigma” is used to designate the distribution or spread (standard deviation) about the mean (average) of any process or procedure.
• For a business, the Sigma Capability (Z-value) is a metric that indicates how well the process is performing.

Quality…a small comparison
• 20,000 items rejections per months
• ~15 minutes each day of unsafe drinking water
• 5,000 incorrect surgical operations per week
• 2 short or long landings at most major airports daily
• 200,000 wrong drug prescriptions each year
• 7 hours without electricity each month
The Classical View of Quality
“96% Good” (4s)
• 7 items rejections per month
• 1 minute every 7 months of unsafe drinking water
• 1.7 incorrect surgical operations per week
• 1 short or long landing at most major airports every 5 years
• 68 wrong drug prescriptions each year
• 1 hour without electricity every 34 years
The Six Sigma View of Quality
“99.99966% Good” (6s)

Six Sigma in Health Care: Why?
1. With the increased focus on customer requirements and
pressure to deliver the best quality every time, cost of healthcare is escalating.
2. It has become of equal importance, to optimize the performance with respect to quality and
to optimize cost of care.
Six Sigma addresses both these [email protected]

What is Six Sigma?
Six Sigma is a “data driven”
problem solving methodology.
… how you utilize and implement that
methodology depends on you.
• A highly Structured and Data Driven Approach for Improved Customer
Quality.
• A Measurement of Our Process and our Capability to deliver services.
• Goal of Six Sigma – Attain Less Than 3.4 Defects per Million Opportunities
Six Sigma?
WHY TO ADOPT LEAN 6σ ?
COME AND FEEL THE EXITEMENT OF LEAN SIX SIGMA IN YOUR HOSPITAL MANAGEMENT.
INCREASE PRODUCTIVITY OF SERVICES.
MORE CUSTOMER SATISFACTION.
MORE VALUE TO CUSTOMERS.
MORE CREDIBILITY TO YOUR ORGANISATION.
MORE INCOME TO YOU…
How income goes up …Before Lean Six Sigma After lean Six Sigma
Low Productivity
More time taken for a process
Normal reputation and credibility
More ERRORS
High productivity leading to more income.
Less time leading to increase in inputs thus resulting in high income.
Increased reputation leading to word of mouth publicity, ultimately giving more income.
Min error resulting in high income.
