ABSTRACT
Lean six sigma is an amalgamation of two
change and improvement methodologies in
business. Together they form a hybrid
approach of improvement that is
comprehensive and allows to increase the
efficiency of the organisation. These two
methodologies have evolved at the same
time in different countries and hence it is
not productive to compare their outcomes.
Rather their forces should be teamed to
produce an improvement in the production
process. However, there is a lack of
understanding about how these
methodologies should be implemented.
Moreover, the application of lean six
sigma methods in context to small and
medium enterprises are also limited. The
following article reviews available
literature reviews and identifies the
common trends and practices. From this
analysis a common approach to the
implementation pf leans six sigma
methodologies has been produced.
1. INTRODUCTION TO LEAN SIX
SIGMA
Lean six sigma is a management technique
through which a team of members and
allowed to collaborate their efforts to
produce enhanced results by eliminating
wastes and reducing variation. It is a
collaboration of two separate techniques:
lean manufacturing and Six sigma. This
method identifies eight kinds of waste that
need to be removed from the operational
system (Furterer, 2016). These have been
defined though the pneumonic
“DOWNTIME”. It stands for defects, over
production, waiting, non-utilised resources
and talents, transportation, inventory,
motion and extra-processing. However, a
unifying framework that can combine
these two methods is still lacking. The goal
of this research is to collect information
from various literature provide a combined
and holistic approach to this method
(Albliwi et al. 2015). It is often defined as
the most challenge yet most rewarding
initiative to ever have been conceived. It
first developed in Motorola in 1980s and
has much evolved since then.
2. BACKGROUND
In order to be able to understand what this
management technique entails; it would be
advisable to look into the details of its
origin. Since, the factors or the
requirements that led to its development
would hold the key for the development of
a uniform frameworks for it. The idea
began with the measurement of product
variation curve (Chugani, 2017). In order
to find a measurement and management
technique that was more suitable to their
own particular needs, Motorola engineers
developed the six-sigma model from the
already established three sigma model.
This became the accepted way to measure
productivity and cultural change within the
company. Unlike the name suggests the
six-sigma method has four aspects, instead
of six that have not been pointed out in any
other business methodologies (Allen,
2019). The six sigma has a clear focus on
the impact to the bottom line. Six sigma
projects cannot be started unless the team
members agree on the amount of saving
that will be generated from it. It has been
very successful in accounting for human
aspects of variation such as culture,
change, focus and training along with
variations possible on the process such as
stability, reduction and capability to bring
about continuous improvement (Kumar,
2016).
Lean is the other method that has also
evolved alongside and can be traced back
to its origin in Toyota production System.
The idea behind lean was to minimise the
waste and addressing the flow issues
within a large-scale company or project. It

was believed that streamlining the flow
would enhance the productivity. These two
methods were combined to bring out the
best results possible. There are five
essential lean principles. First principle
aims to specify the value of the product in
the eyes of the customer. Next principle
will identify the value stream and try to
eliminate the wastes as efficiently as
possible. The third principle believes that
the value flow should be in accordance to
the demand or pull of the customers.
Fourth and fifth principles incorporates the
employees, empowers them and motivates
them to constantly strive for perfection and
improvement (McFarlane, 2019). As was
relayed in the second principle, the wastes
have been grouped into seven parts. These
include the waste of overproduction, time,
transportation, process inefficiency,
inventory, motion and waste generated
through making defective products
(Laureani and Anotny, 2017).
As the popularisation of these methods
grew, they were employed in various
companies, mostly large scale. This often
required the operational framework of the
company to be change in order to adapt
with Lean six sigma.
3. PROBLEM STATEMENT
Lean and six sigma had evolved
simultaneously and both are involved in
enhancing the production and operations in
an organisation. They are well suited
together and are able to bring forth
substantial changes. However, a uniform
framework approaches for the
methodologies combined has not been
introduced. There is also a lack of literary
and research work in the field as a result of
which information about it is also scarce.
There is a need for a new model which is
most suited to the different needs and
requirements of companies as well as
teams (Antony et al. 2016). There are
myriads of frameworks and approaches to
choose from. However, not all of them are
tested and may it may not bring the best
results. It has been suggested that the
frameworks and approaches can be
developed if companies or organisations
record their own lean six sigma
experiences and note down the areas where
they faced difficulties or felt the need to
deviate from the principles along with
specification about the project.
Information from such sources can be
reviewed on a large scale to establish a
basic understanding of the approach to the
methodologies (Timans et al. 2016). On
this understanding further experimental
researches can be conducted to test out
each of the approaches and mark their
strengths, weaknesses and factors of
requirements.
4. AIMS, OBJECTIVES AND SUB
GOALS
The objective of the research paper is to
identify an approach that would be able to
successfully combine the lean and six
sigma methodologies and reduce the risks
involved in the process. Companies all
over the world have employed these
methodologies in within their workplace.
However, these methodologies still lack a
uniform framework. Moreover, these
methodologies have only been applied
with success in large scale industries
(Sunder, 2016). Their applicability and the
possibility of success is limited in small
and medium scale enterprises. These
enterprises form a backbone of the
economy and are also present in larger
number. They also hire larger number of
employees when compared to large scale
companies. As a result, it is essential to
innovate the improvement methodologies
with respect to the needs of small and
medium scale companies.

6. LITERATURE REVIEW
6.1 Lean theory
This theory underpins swift and even flow.
They relate to the process of lean as the
swift and smooth the process is the
productive the results are. The theory is
made up of three main principles. The first
principle is central to lean and relates to
value added and non-value-added work
(Yadav et al. 2016). The second principle
identifies that the processes can move
smoothly only if there are no obstacles
involved. Another way of defining the
principle is that in order to ensure that the
process commences smoothly the obstacles
need to be identified and removed. This
principle is central to the theory of
constraints. According to the third
principle, the flow of processes will be
even better if the variations involved are
minimised.
6.2 Six sigma principles
The six sigma is identified by the DMAIC
principle which is generally applied to the
already existing approaches. DMAIC
stands for defining the problem and the
desired outcome to be achieved after
solving the problem, measurement of the
ability of the involved resources, analysis
of data and identification of the variations
and their root causes in order to eliminate
them. “I” stands for improvement in the
process after identification of variations.
After improvement, it is hoped that the
number of variations will be minimalised.
Every step involved in the process should
be under control (Cherrafi, 2016). This
will enable the project managers predict
and correct any possible variations.
Another group of six sigma principle or
approaches exist which need to be used
when designing new work process. The
acronym for these principles is DMADV.
The first goals for planning a work process

the quality is maintained, a way of

will be able to assess the characteristics of
the process and assemble data related to
quality. Analysis of data needs to be
performed through which the possible

process of verification needs to be carried
out through which it can be assured that
the design though of is best suited. There
are another five concepts that are related to
six sigma (Svensson, 2015). These form
the basis of expectation when six sigma is
employed. According to these concepts,
six sigma allows the organisation to focus
on and give more importance to the
customer requirement, using measurement,
performance indicators, statistical data to
ensure that work get done within the
stipulated time (Snee and Roger, 2018). It
requires the team to be flexible and
adaptable in order to be adapt to any
variations that may occur.
6.3 Integration of manufacturing and
lean six sigma
A key aspect of achieving improvement is
being able to accommodate manufacturing
along with lean six sigma methodologies.
In the integrated system, the
manufacturing is dependent on the
methodologies as no product can be
produced if is not signalled by the
methodologies. Lean six sigma are
involved in accurately reading or
predicting the preferences of the customers
along with market tendencies (Antony et
al. 2016). This information is then
conveyed to the manufacturing department
and the production commences as per the
information provided. In addition to this,
the lean system needs to be in accordance
to the lean system so that they are able to
function smoothly side by side. Along with
lean manufacturing system another lean
six sigma methodology can also be used
through which the continuous
improvement will take place.
6.4 Tools of lean six sigma
6.4.1 Control charts
Control charts act as a tool to monitor the
process of improvement and ensure
stability of the process and that control is
maintained at all steps. It can also be used
as an analysis tool to predict the suitability
of nay given step of the process (Sunder et
al. 2018).
6.4.2 Identifying variations
The charts can be then used to identify the
common variation when the process is
going on smoothly and can be said to be
stable. A process can be said to be in
control when it can be predicted what the
next course of outcomes are going to be. If
it is not in control then the charts will
display non-random variation or special
cause variation (Abu et al. 2015). The
charts can also be used to gain a basic
understanding of the cause of variability.
6.4.3 Four process states
A process can be divided into four stages
mainly: 1. The ideal, 2. The threshold, 3.
The brink of chaos, 4. The state of chaos.
Under the ideal situation the process is
under control and conforms to the
principles of the methodologies (Antony et
al. 2017). The control charts can also help
to decide under which stage does the
process fall under or is heading towards.
6.5 Current status of implementation of
Lean six sigma in small and medium
enterprises
Lean six sigma can be identified as a data
driven process which tries to eliminate the
defects and wastes involved. It lessens the
chances of failures when implemented
correctly and improves the focus of the
process on the ultimate user or the
customer. Current approach of
implementation in small and medium
enterprises is not at all enough to form an
understanding. There is much that is left to
be desired (Sreedharan and Raju, 2016).
An enhances approach pf lean six sigma
framework delineates the need define,
measure, assess, enhance and control the
phases of a process.

resources will be reviewed to understand
the current approaches and frameworks
related to Lean and six sigma

journals were chosen and studied for

the current approaches and frameworks
related to Lean and six sigma
methodologies. Through this approach 15
journals were chosen and studied for
relevant information. They were chosen
based on the research material, relevance

of the topic and context. Journals were
chosen from both online and offline
sources. They all were published after
2015 in order to ensure that the
information collected is still relevant and
applicable. Secondary data analysis was
chosen to be the most suitable data
collection method as the topic chosen was
beyond was considered to be too vast to be
covered through primary data collection
methods like surveys, questionnaires and
interviews. During the analysis of the
journal articles, it was ensured that only
the most relevant and pertinent
information was included in the research.
Also, no personal bias was allowed to
creep into the information. This was
achieved by maintaining an objective
temper of mind in which all the discovered
aspects were dealt with in a detached
manner. The information presented in the
journal can therefore, be vouched to be
true and reliable.
8. RISK ANALYSIS
The involved risk in this research journal
is that the information related to the
approach for implementation of lean sig
sigma methodologies can be biased. The
information has been collected from the
experiences of various companies when
they implemented the methodology. It is
highly possible that they may have
described the process more superficially
and hid the main issues or problems
accounted in reality. This would present a
better picture of the involved team
members and about the company but the
information may prove to be useless. Also,
there are many factors that are dependent
on the nature of the company and people
involved. It is not possible and beyond the
reach of research to be able to enlist and
account for such variations involved.
9. RESULTS AND DISCUSSION
After going through the journals, the most
commonly used approach for
implementing lean six sigma was divided
into five phases. In the first phase certain
critical quality issues were identified by
holding a meeting where customers or the
stakeholders were also involved. This
would help to identify some of the issues
that may have remained unidentified. The
issues noted needs to be aligned with the
internal operations. This way the extent of
the issues can be understood and its direct
and indirect impact will be known. This
will help in later stages when there is a
need for measuring the scope of
improvement. A Lean and six sigma team
will be formulated in the organisation who
are well aware of the methodologies and
how they are applied. They also need to
have an extensive understanding of the
operations of the organisation. The team
will be focused on creating the flow of
processes that are related to the issue. The
flow of process will be streamlined only if
there are no obstacles. The team’s next
topic of focus needs to be identifying the
factors that can act as a hurdle and disrupt
the flow of processes. Other factors that
can be included to improve the flow can be
training and enhancement of technical
devices and the workforce around it. A
maintenance team needs to be established
if they were absent in the organisation.
This maintenance team will focus on the
maintaining the supportive environment
around the process (Thomas, 2016).
Constant monitoring the process using
essential tools is also recommended as this
will ensure greater control over the
process. It has also become apparent that
strong and efficient leadership is required
in various teams surrounding the LSS
methodology. This approach proved to be
most commonly in use however, it
suitability to different field and companies
is not verified.
10. CONCLUSION
It can be concluded that the lean six stigma
methodologies provide drastic
improvement and enhancement of the
work processes when they are
implemented appropriately. However, their
implementation is related to several factors
including the competencies or the people
involved, the approaches of management
and the nature of work involved. The
chosen from both online and offline
sources. They all were published after
2015 in order to ensure that the
information collected is still relevant and
applicable. Secondary data analysis was
chosen to be the most suitable data
collection method as the topic chosen was
beyond was considered to be too vast to be
covered through primary data collection
methods like surveys, questionnaires and

information was included in the research.
Also, no personal bias was allowed to
creep into the information. This was
achieved by maintaining an objective
temper of mind in which all the discovered
aspects were dealt with in a detached
manner. The information presented in the
journal can therefore, be vouched to be
true and reliable.
8. RISK ANALYSIS
The involved risk in this research journal
is that the information related to the
approach for implementation of lean sig
sigma methodologies can be biased. The
information has been collected from the
experiences of various companies when
they implemented the methodology. It is
highly possible that they may have
described the process more superficially
and hid the main issues or problems
accounted in reality. This would present a
better picture of the involved team
members and about the company but the
information may prove to be useless. Also,
there are many factors that are dependent
on the nature of the company and people
involved. It is not possible and beyond the
reach of research to be able to enlist and
account for such variations involved.
9. RESULTS AND DISCUSSION
After going through the journals, the most
commonly used approach for
implementing lean six sigma was divided
into five phases. In the first phase certain
critical quality issues were identified by
holding a meeting where customers or the
stakeholders were also involved. This
would help to identify some of the issues
that may have remained unidentified. The
issues noted needs to be aligned with the
internal operations. This way the extent of
the issues can be understood and its direct
and indirect impact will be known. This
will help in later stages when there is a
need for measuring the scope of
improvement. A Lean and six sigma team
will be formulated in the organisation who
are well aware of the methodologies and
how they are applied. They also need to
have an extensive understanding of the
operations of the organisation. The team
will be focused on creating the flow of
processes that are related to the issue. The
flow of process will be streamlined only if
there are no obstacles. The team’s next
topic of focus needs to be identifying the
factors that can act as a hurdle and disrupt
the flow of processes. Other factors that
can be included to improve the flow can be
training and enhancement of technical
devices and the workforce around it. A
maintenance team needs to be established
if they were absent in the organisation.
This maintenance team will focus on the
maintaining the supportive environment
around the process (Thomas, 2016).
Constant monitoring the process using
essential tools is also recommended as this
will ensure greater control over the
process. It has also become apparent that
strong and efficient leadership is required
in various teams surrounding the LSS
methodology. This approach proved to be
most commonly in use however, it
suitability to different field and companies
is not verified.
10. CONCLUSION
It can be concluded that the lean six stigma
methodologies provide drastic
improvement and enhancement of the
work processes when they are
implemented appropriately. However, their
implementation is related to several factors
including the competencies or the people
involved, the approaches of management
and the nature of work involved. The
information related to such factors were
limited and require further research into
the topic. Providing a suitable approach
was beyond the scope of this journal.
However, in this journal various research
journals related to the implementation of
lean six sigma and the experience of
companies was reviewed. This way a basic
understanding of a suitable approach for
implementation was gained.
