The term "Six Sigma" may seem difficult to
comprehend at times, but is actually very easy to explain. The term is derived
from a character in the Greek alphabet, which is used for representing a
standard variation in statistical mathematics. Statistically, Six Sigma can be
defined as a near perfect method of production that restricts the number of
defects to less than 3.4 for every million opportunities that exist for a
defect to occur. This makes Six Sigma one of the preferred quality management
techniques for achieving near perfect business processes through process
improvement.
Data
Driven And Disciplined Approach
Six Sigma follows a disciplined and data driven approach
for eliminating defects in any type of business process, whether it is the
product manufacturing process or after sale customer service. The two most
commonly used methodologies in quality improvement projects are the DMAIC
process (define, measure, analyze, improve, control) and the DMADV process
(define, measure, analyze, design, verify). The former is used for improving
the quality of business processes that have not met customer specifications and
require improvement. The latter is used for developing new products or business
processes that conform to Six Sigma quality levels. Both the processes are
carried out under the guidance of Six Sigma Green Belts and Six Sigma Black
Belts, who in turn are guided by Six Sigma Master Black Belts.
Companies often want to know exactly how many benefits can
be derived from Six Sigma training. Just to get an idea, one can look at the
financial data of General Electric, one of the companies that have successfully
implemented Six Sigma training. It is estimated that the total value of
benefits derived from the training was close to a staggering $ 10 billion in
the five years after implementation. It is estimated that on an average, Six
Sigma Black Belts help companies save $ 230,000 per project. Given that most
companies can execute 4 to 6 such projects per year, the total savings can
translate into $ 920,000 to $ 1,380,000 per year.
Selection
Process
After selecting the most appropriate type of training, a
company needs to find the right consultant who has the necessary skills and
experience in implementing Six Sigma programs. The selection of the training
consultant will depend on the type of Six Sigma program that the company is
planning to implement. Some programs are implemented all throughout an
organization whereas others are implemented in a specific area only such as
individual functional departments. The decision regarding the selection of the
consultant needs to be made only after consulting other employees, as they are
the ones who will eventually interact with the consultant during the implementation
process.
After getting approval from the employees, it is advisable
to seek references from business associates in other companies that have
implemented such projects and can provide the necessary insights. Companies
need to interview potential trainers and ask questions regarding their previous
work relationships, referrals, total number of candidates trained by them till
date, training materials used, earlier projects they have worked on, and their
qualifications. This is essential since companies need trainers with a great
deal of real-world experience. Companies need to inquire in depth about the
type of training that the trainer is willing to provide. Usually, companies
prefer training firms that operate online help desks for helping clients in
dealing with problems that might arise after the training has been completed.
