1.0 INTRODUCTION
1.1 Background of Project
Lean manufacturing is a systematic approach to identifying and eliminating wastes
(non-value added activities) through continuous improvement by conveying the
product at the pull of the customer in pursuit of production. Increasingly, companies
are striving to create value by using their assets and capabilities to drive innovation
and profitable growth while striving for a positive economic, environmental and social
impact. 2
In its simplest form, lean manufacturing means producing goods with less; it applies
fewer resources without affecting the quantity or quality of the goods produced.
Toyota’s purpose in developing the system was the elimination of waste, and TPS is
focused on seven sources of it: over-production caused by emphasis on supply rather
than demand; wasted motion due to poor processes; waiting time generated by tuning
the production system to the fastest rather than the slowest process; conveyance
waste caused by poorly designed supply systems that delay the transit of goods;
processing waste from badly designed systems; raw material waste from inefficient
design or ineffective supply strategies; and correction waste caused by reworking
badly made products.2
Cutting room is an extremely important section in the garment manufacturing process
which has a major impact on the profitability of the business and is crucial to garment
manufacturing process. The cutting department here suffers lot of problems which add
cost to the company. It requires lean due to: 1
1.2. Problem Definition
Cutting room in Banswara Garments encountered problems like:
1. Improper arrangement of items increasing the search time
2. High fabric wastages
3. Improper man and material movement
5
1.3 Objective
1.3.1 Primary Objective
To remove the non-value adding activities/ waste in cutting department
1.3.2 Secondary Objectives
Optimize fabric consumption in gripper section of cutting
Improve layout for efficient man material movement
Set things in order for easy accessibility
The wider objective is to establish a lean system for future to drive innovation and
profitable growth.
1.4 Methodology
The project is both practical and theoretical analysis in order to find the loopholes in
the department that is challenging the problem. The project will be carried out in
following ways:
1. Study the process and system.
2. Define value stream and map the supply chain from fabric store to cutting to
preparatory section.
3. Root-cause analysis of the problem that is to find the source of the problem
hindering the production flow.
4. Improvement in Process standardization in the areas which is the main reasons of
delay in production flow.
5. Conduct a pilot study with an in-charge to evaluate the operational, technical, and
financial feasibility and its effect on the current setup.
6. Suggest improvements in the proposed system.

1.5 Expected outcome
This project will provide the department with a clear competitive advantage over lead
time as the correct application of the Lean principles will improve or alleviate
substantial benefits that include:
GREATER PRODUCTIVITY , GREATER THROUGHPUT, IMPROVED QUALITY, REDUCED
CYCLE TIMES, SMOOTHER OPERATION - REDUCED OPERATING COSTS, DECREASE IN
LEAD TIME AND MORE IMPORTANTLY AN EFFECTIVE PLANNING OF CUTTING
DEPARTMENT.

2.0 REVIEW OF LITERATURE
2.1 Lean manufacturing
Lean Manufacturing can be defined as "A systematic approach to identifying and
eliminating waste through continuous improvement by flowing the product at the
demand of the customer." Taiichi Ohno once said that “Lean Manufacturing is all about
looking at the time line from the moment the customer gives us an order to the point
when we collect the cash. And it is reducing that time line by removing the non – value
added wastes” (Ohno, 1988).
Waste can be generated due to poor layout (distance), long setup times, incapable
processes, poor maintenance practices, poor work methods, lack of training, large
batches, ineffective production planning/scheduling, lack of workplace organization
etc.
By eliminating wastes in the overall process, through continuous improvements the
product’s lead time can be reduced remarkably. By reducing lead time organization
can obtain operational benefits (enhancement of productivity, reduction in work-in-
process inventory, improvement in quality, reduction of space utilization, better
planning and better work place organization) as well as administrative benefits
(reduction in order processing errors, streamlining of customer service functions so
that customers are no longer placed on hold, reduction of paperwork in office areas,
reduction of labor turnover).
2.2 History
At the end of 1890, Frederick W Taylor became the first to study work management
scientifically and distribute the results. His work led to the formalization of time and
motion studies and the setting of common standards.
Frank Gilbreth then added the concept of breaking work down into elementary time
blocks. It was around this time that the first notions of eliminating waste and studying
movement began to emerge.
In 1910, Henry Ford invented the assembly line for his standardized Ford Model T.
9
Alfred P. Sloan improved on Ford’s system when he introduced the concept of
assembly line diversity at GM.
After the Second World War, Taiichi Ohno and Shingeo Shingo created the “Just in
Time”, “Waste Reduction” and “Pull System” concepts for Toyota, which, together with
other flow management techniques, resulted in the Toyota Production System (TPS).
The TPS has been evolved and improved ever since. In 1990, James Womack
summarized these concepts to create Lean Manufacturing at a time when Japanese
expertise was spreading to the West and the success achieved by companies applying
these principles and techniques became undeniable.
2.3 Eight Wastes in Lean Manufacturing
The waste can be categorized into eight types which is commonly referred to as the
“Seven wastes”. Taiichi Ohno suggests that these account for up to 95% of all costs
in non – Lean Manufacturing environments. These wastes are:
1. Overproduction – Producing more than the customer demands. There are two
types of overproduction (Shingo, 1989):
Quantitative – Making more products than needed.
Early – Making products before needed.
2. Waiting – Typically more than 99% of a product’s life cycle time in traditional mass
production is spent in idling. This includes waiting for material, labor, information,
equipment etc. Lean requires that all resources are provided on a just-in-time (JIT)
basis so that one feeds directly into the next and can dramatically reduce waiting.
3. Transportation or conveyance – Excessive movements and handlings can
cause damages and can lead to reduction in quality. Lean requires the material
be shipped directly from the vendor to the location in the assembly line where it
will be used. This is called Point-Of-Use-Storage (POUS).
4. Over processing or incorrect processing – Taking unneeded steps to process
the parts. Some of the more common examples of this are reworking, inspecting,
rechecking etc. This is due to poor layout, poor tools and poor product design,
causing unnecessary motion and producing defects.
10
5. Excess Inventory – Any type of inventory (raw material or in process or finish
goods) does not add value to the product and it should be eliminated or reduced.
Excess inventory uses valuable floor space and results in longer lead times,
obsolescence, damaged goods, transportation and storage costs, and delay.
6. Defects – Defects can be either production defects or service errors. Having a
defect results a tremendous cost to organizations. In most of the organizations the
total cost of defects is often a significant percentage of total manufacturing cost.
Repairing of rework, replacement production and inspection means wasteful
handling time, and effort.
7. Excess Motion – Any motion that employee has to perform which does not add
value the product is an unnecessary or excess motion. Unnecessary motion is
caused by poor workflow, poor layout, poor housekeeping, and inconsistent or
undocumented work methods.
8. Material loss- The excess of raw materials wastage or finished goods wastage is
termed as material loss. E.g. Excess fabric used for making products and remnant
loss is the material loss incurred in the industry.
2.5 Benefits of lean manufacturing
Typically Lean will improve;
Quality performance, fewer defects and rework (in house and at customer).
Fewer Machine and Process Breakdowns.
Lower levels of Inventory.
Greater levels of Stock Turnover.
Less Space Required.
Higher efficiencies, more output per man hour.
Improved delivery performance.
Greater Customer Satisfaction.
Improved employee morale and involvement.
Improved Supplier Relations.
Higher profits
Increased business.

2.6 Lean Tools
2.6.1. A visual workplace -5S Workplace organization
The primary objective of 5S is to create a clean, orderly environment- an environment
where there is a place for everything and everything is in its place. Pictures are very
effective at visually highlighting the improved appearance and order in the workplace.
Figure 2.1 5S Methodology
A. SORTING
Sort means that one removes all items from the workplace that are not needed for
current production operations. After investigating upon the relevance of each data or
and deciding what is needed and what not, the people related to that process were
trained so as to make them understand that how they should get rid of things not
needed and when in their routine working schedule.
B. SET IN ORDER
It is defined as arranging needed items so that they are easy to use and labeling them
so they are easy to find and put away. Setting in order depends on the frequency of
use of the item. In this the ways activities, materials needed, to be devised in such a
way that anybody can find things easily and put them away where they belong easily.
Setting in order can be done by using various tools like
o Labeling
o Painting strategy
o Sign board strategy and many more.
12
C. SHINE
After the setting in order is done, shine comes next. Shine is one of the basic activities
but it is no less important for its lack of novelty. It’s based on:
1. Do not wait till things get dirty. Clean your workplace machines and equipment’s,
tools and furniture regularly so that they do not have a chance to get dirty.
2. Prepare cleaning schedules and assign a person responsible for equipment’s and
Maintenance of an area or storage.
D. STANDARDIZE
For this the implementations done initially should be so explained that they are easy
to follow. Through this everybody will know the right away when there is a problem
and will be able to keep things the way they should be. With this, abnormalities in the
workplace can be made obvious. Everyone related to the concerned department was
trained about the meaning of all visual cues used and how and when to take actions
accordingly.
E. SUSTAIN
In sustenance, it is important to make a habit of properly maintaining correct
procedures. That is why it is so important to practice, because practice reinforces
correct habits. It requires regular inspection and motivation.
2.6.2 Kaizen- continuous improvement
Kaizen involves setting standards and then continually improving those standards.
Standardize an operation and activities.
Measure the standardized operation (find cycle time and amount of in-process
inventory).
Gauge measurements against requirements.
Innovate to meet requirements and increase productivity.
Standardize the new, improved operations.
Continue the cycle continuously. Key elements of kaizen are quality, effort, and
involvement of all employees, willingness to change, and communication.
13
2.6.3 LEAN LAYOUT Lean Based Plant layout refers to the arrangement of physical facilities such as
machines, equipment, tools, furniture etc. in such a manner so as to have quickest
flow of material at the lowest cost and with the least amount of handling in processing
the products from the receipt of raw material to the delivery of the final product.
a. The Facilities Design Problem
Researchers classify the global problem of facility design (Layout Design) into three
interrelated tasks:
(1) The layout problem – placing the manufacturing resources (machines,
departments, or cells) within the available floor area (block layout),
(2) The input/output station location, and
(3) The determination of the network system to support material flow interaction
between facilities.
The layout problem is concerned with finding the most efficient arrangement of the
facilities within the available floor area. Having the impact of material flow systems on
the layout design described, some authors suggest the simultaneous consideration of
the first two design tasks; others adopted a sequential approach taking the complexity
of the designs into account.
b. Data Requirements for Layout Decisions The models for developing the block layout require the following parameters as inputs
• Frequency of trips or flow of material or some other measure of interaction
between facilities
• Shape and size of facilities
• Floor shape available
• Location restriction for facilities, if any
• Adjacency requirements between pairs of facilities, if any

2.8. Gripper in Trousers
A gripper is a fabric of small width used in making waist band which comprises two or
more fabric including piping and stitched by using canvas in to the width of the garment
waist.
Figure 2.2 Gripper in Trousers
The gripper section involve procedures, which are described below:
1. For making gripper the rolled fabric is stitched with the use of SNED through
salvage in which both ends are stitched removing salvages.
2. Then it biased using Fabric biasing machine at 45 degree and rolled it again.
Here the fabric width and length gets changed.
3. The fabric length gets increased due to elongation of fabric because of elasticity
and that of width gets decreased because of rolling it in bias.
4. Now using Rolling cutter it is cut into the required parts in the rolls (usually
length is in mm) and end part which is not aligned perfectly is cut into waste.
5. Then using sewing machine and folders gripper is made.

3.0 METHODOLOGY
3.1 Procedures
The project is both practical and theoretical analysis in order to find the loopholes in
the department. The project will be carried out in following ways:
Study the cutting operations and its components and their standard operating
procedures
Define activities from fabric store to cutting to preparatory section.
Root-cause analysis of the problem to find the source of the problem hindering
the production flow.
Improvement in Process standardization in the areas which is the main reason
of delay in production flow.
Conduct a pilot study with an in-charge to evaluate the operational, technical,
and financial feasibility and its effect on the current setup.
Suggest improvements in the proposed system.
Standardizations of the system.
3.2 Data Collection techniques
Primary data was collected from the cutting section of the company on fabric
consumption in gripper and layout of this section. Data was collected by on spot
observations and interviews with the operators, supervisors and management.

4.2 Findings
The inefficiencies in the cutting processes arise from following areas:
There is no separate receiving area reserved for the incoming materials from
cutting. As a result the incoming materials are directly stored in random locations in
the warehouses which in turn causes the handling and relocation of materials during
the retrieval of the materials to be high.
There is no temporary storage area for the work-in-processes i.e. fabric that the
work-in-processes are transported back to the warehouses for temporary storage.
This is long distance transportation which needs a lot of handling and transportation
efforts.
Some facilities which are required for consecutive processes are located in
different locations. As a result the materials which have been processed in one of
these facilities have to be transported for long distances to get them to the next
facility.
The fabric store in Cutting department took so much areas which could be utilized
for keeping the trolleys for transporting in the Sewing Lines.
The space for fusing material were not perfect. As for the increase in capacity of
fusing led to the utilization of space which is not there in the current existing system,
so the fusing materials were placed in preparatory section.

5.0 IMPLEMENTATION OF 5S
5.1 Scope of 5S in cutting department
The project started with the cutting department. The processes covered for project
implementation were:
Figure 5.1. Categorization of 5S in cutting
In the above mentioned activities only the two S’s were covered individually i.e. Sort
and Set in order.
5.2. About the Cutting department
There were total 58 employees in the cutting department which includes CAD also.
There are five spreading table, There was one automatic spreader and CNC cutter.
There were four straight knife cutters. Four panel checking table. The average
production of cutting department was 4800 pieces per day depending upon whether
the fabric is solids/stripes/checks.
20
5.2.1 Spreading and cutting section- Existing system
The cutting in charge brings the lay report in bulk. Spreader looks for the fabric
available in the racks for the respective lay reports in fabric store. They start with
the laying of the cut no. (Lay report) whose fabric is available.
The table planning is done by the spreaders only. If no. of plies is more for one
marker, no. of plies in one lay is decided by the spreader. This is separated among
the various tables on the floor.
If one lay report is broken down into more no. of lays. The extra marker has to be
plotted or the sticker has to be generated.
Shade card is received along with the fabric from the store.
Now starting with the lay report, the spreaders first do the shade segregation of
all the rolls of a particular cut no. and color.
Start the spreading with first roll.
Once the roll gets finished the end bit left is entered in the lay report along with
the no. of plies spread with the particular roll, shortage if any, shade, lay length,
marker width, meters used, roll no.
The end bits are just kept in the racks aside without writing roll no. and meter left.
Separate register was maintained for end bits, spreading and the shortage in the
rolls.
Marker is spread over the lay. Then after cutting is done.
If the cutting is done on the CNC cutter the sticker are generated for each part.
Then after cutting is done.
If the fabric is solid it is directly send for the ticketing and bundling.
If the fabric is stripes or checks it is send for the pinning then ready cutting in the
end for numbering and bundling.
5.2.2. Spreading and cutting section- Possibility of 5S·
The rolls from the stores are stacked in the racks anywhere and in any manner.
Some of them are left on the floor just because there is no space left in the
racks.
At the time of shade segregation if the rolls are kept below, first all the rolls are
removed from above. The required rolls are taken out and kept on the floor.
Shade marking is done. The rolls are left on the floor. There is no temporary
store in the department.
21
Half of the racks in the roll storage were full of end bit and other objects.
End bits stored in the end bit racks were very haphazard. If the racks are full
they are stuffed in the cartons. At the time of re-cutting getting fabric from the
Racks and the carton is near to impossible. Sometimes the re-cutting is not
done as a result the order quantity is not met.
The table on which the record maintenance for end bits, spreading and
Shortage was done was big mess. All the lay reports were kept on that table.
Every time the roll gets finished the spreaders comes and search for measuring
Tape, lay report. Shade cards are also kept on the same table. All the day end
bits are piled on the table. The places are not fixed for anything.
No specified space for throwing the roll left over. They were thrown in a corner
or may be near the table or in front of the end bit racks. This was hindrance in
the operation.
There was a small dust bin which was not enough to suffice the requirement in a day on an average 80-90 rolls were laid.
5.3 Implementation of 5S in cutting and spreading
5.3.1 Sorting The first activity considered was the Temporary Roll storage. There are 12 racks for
roll storage in which:
Fabric rolls- Temporary storage of rolls, fusing rolls – under the spreading
table.
Plotting paper – 3 rack
End bit cartons – 2 racks
Spare parts 2 racks
Dead stocks 2 racks.
Panel or cut parts racks-3
Out of these end bit cartons, spare parts and dead stocks were removed which were
not needed in the work place area which resulted in increase in number of racks for
fabric roll storage to 9.
22
5.4. End bit storage- Existing System
There were no racks for end bits each.
5.5 Implementation of 5S in End bits area
Total end bits left after re-cutting and once the shipment goes is just 1%
In one day around 6240 mtrs. of the fabric was used
1% of 6000 is 62.4 mtrs. (can be stuffed in a carton)
Per day one carton is created
Capacity of the five racks is to accommodate 45 cartons.
Now this can be concluded as, after every 45 working days the end bits has to be
given to fabric store.
Figure 5.2 - End bits area before implementation
5.5 Implementation of 5S End bit
5.5.1 Local Red Tag Area The area consists of end bits of rolls.
The End bits would be arranged according to buyer wise and style wise.
To be used will be kept in the box and other not to be used will be kept as in
Racks.
23
Figure 5.3 - Local Red Tag Area
Figure 5.4- End bit storage
Next activity considered was end bit storage. There are two end bit racks each
containing 12 shelves. Out of these, both were placed on right end of roll racks and
one rack on left end of roll racks. We shifted all the two rack in one place. This will be
helpful in reducing time for searching the end bits which were now placed in a single
location. Cartons full of old end bits were kept all over the end bit storing area. Those
cartons were then reallocated to the local red tag area defined.
24
Figure 5.5: - End bit racks area (after)
5.5.2 Introduction of new system
Placed 3 racks for end bits each having 36 shelves, total 108 shelves.
Nomenclature them with no. starting from 1 to 108
Introduced a register containing following columns: Swatch
Roll no.
Color code
Shade
Measurement of end bits
Shelf no.
Shortage if any
Remark
Once the roll gets over the spreader keeps the end bit in the shelf (end bit racks)
and enters the shelf no. in the register. This helped in keeping the record of all
the end bits left and the location where it is kept in the shelves.
Now the Re cutting operator doesn’t have to go through all the 108 shelves for
searching one end bit. He/she refers the register gets the shelf no. in which the
end bits are kept.
After every 5 days the end bits whose shipment is complete is taken out from
the shelves and kept in the carton. These cartons are then kept on top of the
roll racks. These end bits are then sold after every 45 days when the top of the
roll rack is full with cartons (as mentioned before in local red tagging area).

Figure 5.9 Roll waste in dust bit (After)
5.5.3 Set in order the system
Setting in order the temporary roll storage was very important. The delay in roll retrieval
from the roll racks will have direct effect on the output of the cutting department.
Following steps were taken in order to setting order the temporary roll storage:
27
5.5.4 Segregation and labeling the roll racks
All the racks for temporary roll storage were labeled. Depending on the order quantity
the racks were assigned for each buyer. Racks were assigned for different buyer as
follows:
For:

5.5.5 Fusing
Once the labeling of the roll racks was done the spreaders don’t have to waste time
searching rolls of particular buyer in all the 20 racks. It can be easily located by seeing
the labels. Once the fabric rolls come from the store they know which cut no.
(Mentioning the buyer name) has to be kept in which racks.
Following figure is more explanatory.

Segregated loading racks as per the line
After bundling and ticketing, the bundles are stored in the loading racks. Now the
loading racks are divided according to the lines where a particular cut no. will be
loaded. Three racks have been assigned to each sewing line. A board is attached to
one of the rack of one line. It has three contents
Line no.
Cut no.
Swatch
During planning only it’s decided that in which line, which cut will be loaded. After this
only, respective swatches and cut nos. are mentioned on the boards. After bundling,
the helper will stack the bundles of all the parts on the respective rack where its swatch
is present. During loading also, the helper of the line will come to the rack of its
respective
Sewing line and take the part instead of searching on all the racks. The figure below
shows how the racks will be divided according to the sewing lines:

5.5.8 Shine
To start with shine in the cutting department, we first divided the whole cutting
department into various zones depending on the type of activity and the present
layout of the department.
All the operators were informed that how the whole department has been divided.
As per the zones, all the operators working in each zone were made responsible
for maintaining their respective zones.
Depending upon the activities in each zone the operators were instructed the areas
in which they have to work upon. This instructions are listed as a
5.5.9 Standardization and Sustenance
Checklist (Refer to annexure b)
Checklist was developed for each zone depending on the activities.
This checklist was graded on daily basis by the cutting department team leader.
In the end of the month the zone having highest grade will be rewarded
This helped in developing a competition among the operators for keeping their work
place in order and clean.
This acted as a motivation for them to understand the importance of cleanliness.
Keeping things in order reduced the chaos at the work place in future.
Before making them understand the importance of cleanliness and orderliness in the
workplace, few photographs were clicked in order to show them the present condition
of their workplaces which was unorganized and dirty. They realized that how their dirty
workplace effects their work culture and other activities.

6.0 Gripper section
6.1 What is a gripper?
A gripper is a fabric of small width used in making waist band which comprises two or
more fabric including piping and stitched by using canvas in to the width of the garment
waist.
The gripper section involves many procedure, which are described below:
The gripper section has 3 main parts
1. For making gripper the rolled fabric is stitched with the use of SNED through
salvage in which both ends are stitched removing salvages.
2. Then it biased using Fabric biasing machine at 45 degree and rolled it again.
Here the fabric width and length gets changed.
3. The fabric length gets increased due to elongation of fabric because of elasticity
and that of width gets decreased because of rolling it in bias.
4. Now using Rolling cutter it is cut into the required parts in the rolls (usually
length is in mm) and end part which is not aligned perfectly is cut into waste.
5. Then using sewing machine and folders gripper is made.
6.2 The Existing System
Figure 6.1The existing system
Planning Department calculates the required Gripper
consumption and send it to the fabric store.
Fabric store issues the required fabric to the cutting department-

Gripper department make the required quantities of gripper
The remaining fabric is unusable and is stored in temporary store

6.3 Problem identification
The gripper section faced two king of problem in the department:
6.3.1 Wastage of cut rolls. (Fabric wastage)
There were huge loss of fabric as the issued fabric were high.
Problem in the gripper section was the Actual consumption of fabric were
less in making gripper than the forecasted consumption.
In such cases the store department used to order more fabric than the
actual required.
They didn’t had the Database of actual consumption for the similar
varieties of gripper.
Fabric could not be used again as they were biased and cut according
to the following order and also could not be reused for sampling.
So the loss were high in monetary term.
6.3.2 Ineffective layout of gripper section.
1. The material movement were high in gripper section as the stitching and the
fusing section .were at different places and material and man movement
were high.
2. Storage of fabric i.e. temporary store and racks are inappropriate and there
is difficulty in finding rolls.
3. No plan for the use of remained fabric.
The gripper section involves the process in which the length of the fabric gets
increased and the width gets decreased. The below chart shows the percentage
increase and Decrease in length and width respectively.

6.4 Data collection of fabric wastage in gripper section
The data collected on the basis of amount of fabric in store remaining and analyzed it

7.0 RESULT
7.1 Lean layout
There were decrease in the spreader movement from 48 mt. to 1.28 mt. which enhanced
the productivity of spreader due to decrease in movement time.
Space for keeping trolley were less and hence removing old fabric store from cutting
benefitted in making permanent space for trolleys. The Fabric store took 38 mtr. Which
were now used in keeping trolleys.
Man material movement were complicated and hence change in layout simplified.
7.2 In 5S Implementing 5S in cutting for keeping end bit fabric and re-cutting section saved up
to Rs.132, 000 per year and operator required got minimized.
7.3 Fabric Saving in Gripper Section
For the running order the fabric calculation in gripper section the company benefitted
Rs. 35641.8
The reports and procedure for gripper fabric calculations were given to IE department
and Sampling department for exact measurement of gripper.

8.0 CONCLUSION
Lean production is all about reducing waste. This involves working more effectively with
Lead time. The teamwork approach is a recognition that the best way to achieve this is for
all members of the workforce to be involved to achieve a quick response. Lean
Manufacturing and Lean Thinking are about eliminating waste, or muda from the
production system. It is about identifying non-value added activities in your processes and
eliminating them. The results can be dramatic, but the journey is challenging.
Lean production has enabled Banswara to cut out waste in the production of the garment.
The successful implementation of lean production at Banswara cutting department will
form the benchmark for the systems.
The lean strategy were followed and made very impactful on both workers and managerial
Level and are keen to work for lean manufacturing in all other departments. They also
seek for new methods according to lean which can enhance their productivity at all levels.

9.0 LIMITATION
Lean thinking minimized the level of waste and caused positive radical changes in the
industrial sector. On the other hand, there are limits that make lean inapplicable and is not
worth it.
Lack of Acceptance by Employees
Lean manufacturing processes required a complete overhaul of cutting operations that
caused stress and rejection by some employees. It required constant employee input on
production, which some employees may feel disinclined or unqualified to do. There may
also be some difficulty finding managers with sufficient leadership and persuasion skills to
overcome this. To fully benefit the company for Lean implementation, both the concept and
techniques should be considered at both employee and managerial level. Also, time was a
major constraint to track the implementation in the long run.
