Book preview

Module 1:  What is six sigma?

Introduction:

Companies encounter many problems such as:

Customers rejects

Low sales

High competition

Selling defected products

Profit decrease

High operating cost

Machines downtimes

Shortages in storing areas

More and more....

The question is what we should do. What is the best method to tackle these problems?

The essential equation applied, the company needs to work on, and to manage its profitability is:

Value  =  Selling price  -  Costs 

Value is determined by costs

Selling price fixed by the market prices and competition.

Costs are within the control of the company

This equation is oriented towards the customer who pay for the value of the product.

While, if we consider

Selling price =  Costs  +  Profit

We are looking for the company profit only.
