The document provides an overview of Six Sigma, explaining it as a data-driven methodology for process improvement aimed at enhancing quality by minimizing inefficiencies. It discusses key concepts like DPMO (defects per million opportunities) and various quality management tools associated with Six Sigma, such as SIPOC analysis and value stream mapping. Additionally, it outlines different types of data variations used in Six Sigma, focusing on the importance of data collection and analysis.

2. Q1. What do you mean by six Sigma and
elaborates its principles?
To be precise, Six Sigma is a set of techniques and tools devised for process
improvement. The idea here is to take the decision's based and backed with the
data-driven disciplined methodology that not only when improving the transaction
as well as the product to service operations. The concept of six Sigma is drawn from
various other concepts related to engineering, but her bright gentleman named bill
Smith who was working as a plant manager in Motorola in 1986, came with a model
called six Sigma to promote quality by reducing inefficiencies and wastes to the
lowest possible units in the sample.

3. DPMO Stands for defects per million opportunities,
while DPPM stands for defective parts per million.
When we consider the flow of the production in
any given industrial unit or production unit, we find
that quality is often compromised due to many
reasons, and one is ineffective training given to the
Labour force.
The companies, as well as industries, focused more
on productivity by engaging the Labour force in
committing to their work as per the piece which
system. And this is the reason that often the
quality is compromised in order to gain maximum
outputs in the shorter time possible.
Q2. Define DPMO or
DPPM?

5. Q4. List out the different
kinds of variations used in
six Sigma?
Mean, median, range, and mode are some of the
common variations that are used in six Sigma. The
whole step starts with the collection of data with a
clear picture in mind of all the factors that can
impact the collection. As per the six Sigma
principles, we can divide data into two major types,
and they are quantitative and quality. Quantitative
data comes from continuous data, and the discrete
data forms a major Attribution to the qualitative
data category.
