DPMO
Defect Per Unit (DPU) :
Total number of defects in sample divided by total number of units.
Opportunity :
A unit may have more than one type of defect.
Each is an opportunity.
Ex: A watch case may have pits, burr etc.
Defect :It is a feature in a product or service that causes dissatisfaction to the customer.
MSI: SS: GB: PR; 01:04

33
DPMO
Defects Per Million Opportunities (DPMO) :
DPMO = (DPU) * 1 Million / Number of opportunities per unit OR DPMO = Defects per opportunity (DPO) * 1 Million
Parts Per Million (PPM) :
A Number taken as reference from the sum total of one million
Ex. If 100 items are found defective from total numbers of items of one million. It shall be referred as 100PPM
MSI: SS: GB: PR; 01:04

DPMODefects Per Million Opportunities (DPMO) :
DPMO = (DPU) * 1 Million / Number of opportunities per unit
Ex: We checked 500 Purchase Orders (PO) and (PO) had 10 defects.Then DPU = d/u = 10/500 = 0.02
In a PO we check for the following: 1. Supplier Address/approval 2. Quantity as per the indent 3. Specification as per the indent 4. Delivery requirements 5. Commercial requirements• Then there are 5 opportunities for the defect to occur.• Then, the total number of opportunities = 5*500 = 2500
• DPO = = 10/2500 = 0.004• DPMO = DPO* 1 Million = 4000

Six sigma is a management tool that helps in identifying the root causes to:
Why ”Sigma“? Sigma(s) is a Greek letter which stands for standard deviation, that measures how far a given process deviates from perfection.
What is Six Sigma?

• The term “sigma” is used to designate the distribution or spread about the mean (average) of any process or procedure.
• For a process, the sigma capability (z-value) is a metric that indicates how well that process is performing. The higher the sigma capability, the better. Sigma capability measures the capability of the process to produce defect-free outputs. A defect is anything that results in customer dissatisfaction.

• A systematic approach to process improvement.
• Processes can be related to design, manufacturing or administrative functions.
• It involves the use of statistical tools and techniques to analyse & improve processes.
• The relentless pursuit of variability reduction and defect elimination.
