Global Companies’ Management Secret is Greek, SIX SIGMA!

The fast paced economy, constant demand for change, consumers demand for more superior product, and much more has challenged a lot of different companies for years, different management philosophy have been developed in order to cope up with those challenges. And one of these is SIX SIGMA. It was developed by Motorola in 1986 and has been regarded as the most popular management philosophy in history. Currently, Six Sigma is in itself a colossal brand name in the corporate world. Previously Six Sigma has only been used by big industrial companies however; nowadays government offices, armed forces, hospitals and even prison management have incorporated Six Sigma in their management schemes. Six Sigma can be defined as a holistic management program focusing on the alleviation of defects on products and services by producing high objective, collating data and analyzing the data thoroughly.

Motorola, Inc. and GE have both through the years developed their own definition of SIX SIGMA. In this article, Motorola’s SIX SIGMA will be discussed.

Motorola Inc. defines SIX SIGMA at three different levels:

1. Metric – the terms Sigma is a Greek letter that is often used as a scale for goodness or quality of a product. In this scale, SIX SIGMA means that 3.4 defects per one million opportunities (DPMO). SIX SIGMA was actually initiated in an effort to reduce defects and was then used in different business processes for the same purpose.

2. Methodology – where in Six Sigma is represented by the acronym DMAIC which means;
a. Defining Opportunity 
b. Measuring Performance
c. Analyzing Opportunity 
d. Improving Performance
e. Controlling Performance
The acronym is the heart on how SIX SIGMA works in order to understand consumer demand and manage the company’s production to produce highly valuable products and services.

3. Management – after years and years of practicing the SIX SIGMA philosophy, Motorola has learned that in order to be successful, process metrics and a well defined methodology should be applied using improvement opportunities together with the organization’s strategy.

Additional information, SIX SIGMA actually uses statistics and data analysis to realize the situation and find out the root cause of the problem and how to improve it.

    The Cycle of Improvement: DMAIC

    DMAIC means

    It is an improvement cycle that is data-driven utilized for optimizing, improving and stabilizing the business design and process. This cycle of improvement is a tool to drive the Six Sigma projects. The DMAIC process is not only limited to Six Sigma. It can also be used for other improvement projects too.

    The DMAIC steps need to be done in the proper order, and each step should be accomplished first before proceeding to the next.

    This step involves listing down what you know, seeking to clarify the facts, setting objectives and forming the team for the project.
    The following are needed to be defined:
    The statement of the problem
    The clients or customers
    The CTQs or Critical to Quality and critical process outputsDMAIC
    The process to be targeted and other business processes that may be related to it
    The Project’s targets
    The boundaries of the project
    The project charter – agreed and created during this step

    This step is where data collection happens. The team determines what to measure and how to measure it. A data collection plan is created on this step. Investing a lot of time and effort in assessing the suitability of the measurement system proposed is quite usual.
    The following are needed for this step:
    The process critical inputs (X) and outputs (Y)
    The plan of measurement
    Testing of the system of measurement
    Collection of the data
    A gauge study or Measurement System Analysis

    During this step, all the data collected in the previous step is analyzed to detect the main causes of the defects. Basic and complex analysis tools are used during this step.

    The improvement step involves formulating creative solutions and minimizing process problems. Brain storming techniques such as Random Word and Six Thinking Hats could be used in this phase. Others prefer to use the more complex analysis tools such as the Design of Experiments (DOE).

    This final step includes the monitoring of the improvements to ensure the continuity of success, creating a plan of control and updating all records and documents as required.
