When you hear the term six sigma, one
question that will come to your mind is what is Six Sigma? a running attitude developed
by Motorola that highlights setting with extremely high aims, collecting data,
and examining results to a find degree as a method to decrease faults in
products and services. The Greek letter sigma is sometimes used to denote difference
from a standard. The viewpoint after Six Sigma is that if you calculate
how many faults are in a process, you can work out how to analytically eradicate
them and get as close to excellence as possible. Consecutively for a company to
attain Six Sigma it cannot make more than 3.4 faults per million opportunities,
there are two main methods in Six Sigma, those are DMAIC and DFSS.
Following are some of the relevant
features of Six Sigma methods:
- Six sigma is a data driven approach - Six Sigma
provides us with sequence on which and what type of data should be
collected, how it should be put together and how it should be scrutinized.
- Six Sigma is a course focused methodology- the whole
thing that is done at the office has a procedure behind it. To bring perfection
it is all the time good to learn the fundamental process together with the
results, particularly if we are looking for a long-term improvement and
not a short-term temporary solution.
- Six Sigma provides a planned step by step roadmap -
If a business problem is being determined by a cross serviceable team over
a period of time, it pays to use a prearranged methodology (like
Define-Measure-Analyze-Improve-Control) with review stages.
- Six Sigma uses non reasonable approach - Example - To
progress customer fulfillment indicators by 25% in 4 months time, you
would need not one but a series of non rational approaches which Six Sigma
offers.
- Six sigma integrate the best of tried and
tested management methodologies over the years - Six Sigma has merged
various time tested management techniques in one roadmap. Also, Six Sigma
is not inflexible. It is a growing methodology. New tools are being added
to the Six Sigma toolkit by original practitioners.
- Six Sigma expansion projects are generally authenticated
by fiscal advantages or by collision on a KPI (Key Performance Indicators)
- Six Sigma works on improvements on a project by project
basis by people trained as improvement experts (called Green Belts and
Black Belts) - Improvements can be brought on a project by project basis
and by no other way. Unless development regions are transformed into
projects, with allocated responsibilities and authorities to properly
trained people, the troubles remain what they are.
