ABSTRACT:
The Business environment of Apparel Industry is getting very tough recently Many apparel brands were being closed such as Gymboree, Limited, Guess because they can’t attain their customer’s loyalty Company tries to cut cost, competition between fashion companies is being hot than ever and the demand for higher quality with low price is increasing
And as an Agent QA, we are paid by customers to work with suppliers to deliver the right quality of goods to them As a cost center for customer, how are we still survived in this context?
The right answer is to try at our best to work closely with manufacturers to improve the overall quality performance, try to do right first time, deliver the right products to our customers
My thesis will discuss about the quality improvement in a fashion garment manufacturer through practical study The paper deals with an application of methodology in an industry which provides a framework to identify, quantify and eliminate sources of variation in an operational process, to optimize the operation variables, improve and sustain process performance with well-executed control plans The application of this paper improves the process performance of the critical operational process, leading to better utilization of resources, decreases variations & maintains consistent quality of the process output The consequence of my report is to prove that factory can achieve higher quality performance and enhance customer satisfaction by minimizing reworks activities through proper utilization of company's internal resources without the need of significant investment

INTRODUCTION
Quality has become one of the most important decision-making factors for customer purchasing product Many companies invested a consider amount of human resources, capital and time to build the right quality system However, in many cases, quality system and improvement models, method and tools are poorly deployed and led too many frustrated issue for company Therefore, a smart garment manufacturer will not underestimate the significance of quality for his business Garment manufacturing is a complex industry for many reasons The product is manually operated, limited knowledge
of the workforce, less data analysis to know where is the root causes So how to utilize Total Quality Management (TQM) tools in managing quality performance in existing sections is the headache challenges to the Middle Management in factory To support factory in handling and utilize effectively TQM tools, I here introduce and apply again its tools in specific control activities to improve and maintain the quality performance in each section of the factory
BACKGROUND OF THE STUDY:
Business environment context of fashion industry is changing rapidly, order quantity is getting smaller, style quantity is increasing It requires both Li & Fung staff and factory have to be adapted with this scenario flexibly More than that, an Agent’s QA, who is responsible for quality assurance of all shipments delivering to our customers, needed to persuade factory to look into their current system and flows to see where they are, then consolidate and improve immediately the pending gaps to consistently provide the good products to our customer
And standing in between customer and supplier’s quality performance, I always try to work with our QAs and suppliers to deliver the goods to our existing customers with acceptable quality and reasonable price Choishins(Vina) is one of my in-charge factory and its performance is not good enough and there are reports of customer receiving goods with quality issues Delivery performance also not at that good, merchandise only completed at the last minutes and factory even doesn’t have enough time to conduct pre-final in prior of agent’s QA audit Sometimes we face with difficult situation because of final audit failed and the goods can’t meet handover date We can’t continue like this way as it doesn’t enhance our customer satisfaction at all and it is important to convince factory management
to change
Trang 14iii
However, the culture “Fear of Change” is being existed in the mind of the stakeholder from
my in-charge factory I should prove to them that by seriously applying TQM tools in inspection, production processes and TQM knowledge training, we can increase accuracy
of operation handling and inspection Then we will overcome current unexpected performance and enhance our customer satisfaction
OBJECTIVES OF THE STUDY:
The objective of this study is to find out how we can improve effectively the quality of garments by implementing TQM tools (Check sheet, Pareto analysis, Process flow chart, Cause-Effect diagram) Setting more positive TQM environment in between the teams The main possible consequences of this study are:
- Improve TQM knowledge of the teams
- Reduce non-value-added works from process
-Quality performance can be improved by solving the problems behind poor quality
- Productivity can be improved by reducing rework
SIGNIFICANCE OF THE STUDY:
In today market environment, apparel company is being faced with multiple challenges such as increasing wage in production countries and Viet Nam is one of the region that is having high cost, downward pressure on garment prices Simultaneously, the rise of fast fashion with reducing order quantity and lead time while increasing order frequency This new world of lower volume, higher mix products creates a need for Agent’s QA who is responsible for quality assurance of all shipments deliver to our customers, to work with factory to improve and maintain its right first time performance and efficiency
Quality performance is the vital point to attain the reputation in the eyes of our existing customers and sustain competition, MY ROLE is to increase the inspection accuracy while reducing non-value-added works After worked with me on this project, factory can get benefits from different categories as below:
-Business result:
Improve customer satisfaction
Enhances organization’s image and reputation
Trang 15iv
-Culture:
Increase quality awareness through all level of organization
Improve focus and involvement of senior management and staff in Continuous Improvement
-Process Management:

Fully aware of TQM tool’s benefits
Be able to use TQM tools effectively
Know how to track daily/hourly production KPIs
RESEARCH METHODOLOGY:
Initially observe on how factory system works to understand the overall manufacturing & quality processes This step helps to understand the plants, what method they follow, how quality system works Using benchmark of Dale and Lascelles (1997) model to assess maturity of factory’s Quality Management System In the meant time I also checked factory TQM implement against TQM 8 Elements Collect quality performance data of Cutting, Sewing, Finishing Using TQM’s 7 tools such as Pareto, Check sheet, Cause and Effect analysis, 5 Whys etc to analyze the collected data and find out the root causes
Then set up the Performance Improvement Committee, conduct the TQM knowledge, quality concepts training for all management and workers, introduce of Inline Inspection
on Sewing floor through a pilot line firstly, adjust manufacturing flows to eliminate the wastes, take corrective actions to solve quality issues from the defined root causes
Trang 16v
REPORT OVERVIEW:
The 1st Part of my report focus about Assessment and Analyze the current quality system
of Choishins(Vina) There are 2 chapters ins Part I, Chapter 1 is reviewing of the existing flow in different departments such as cutting, sewing and finishing section of the production floor of factory in order to understand the overall manufacturing & quality process including materials flow This step helps to understand the plants, what method they followed, how it works And in Chapter 2, I used the benchmarked check sheet to assess into factory’s system to measure the company maturity and used 8 TQM elements
to check how TQM application in factory Collect data to identify majorly problems occurring in factory and utilize the TQM tools of Pareto, Fish Born, Five Whys to analyze and find out the root causes
The 2nd Part of my report will mention about Improvement Plan from my findings about TQM implementation in factory as well as physical defect’s root causes There are 2 chapters in this part In Chapter 1, will mention about the source of improvement and chapter 2 will focus about Action Plan Tracking of improvements and comparing them with previous situation in different departments

Trang 204
Figure 3 Factory Organization Chart
From above organization chart, we can see that the administration team is leading by Mr K.J Won, Production team is in charge by Mr K.H Soo and Quality department is looking after by Ms Anita It is good that quality team is directly reports to General Director
CHAPTER 2: REVIEW OF THE EXISTING QUALITY SYSTEM AND MANUFACTURING PROCESS IN CHOISHINS(VINA)
2.1Description of Quality System:
2.1.1Quality Policy:
Deliver the products with free of defect to customer with reasonable price! And enhance quality system to satisfy customer expectation
2.1.2 Quality Management System in factory:
Company has built up quality system and manual but it was not accredited by third party And since factory is producing products for different buyers and Choishins is applying the standards of different buyers into their running system
2.1.3 Quality Performance Objectives:
It is surprised to me that factory does not have specific goal for each department about quality performance goals According to Mr Kwon, he sets target for the teams to pass 100% final audit by buyer QC
2.1.4 Total Quality Management System:
Applying 5S tools
Using check sheet to capture the defects but did not see factory doing analysis
Trang 215
2.1.5 Environment management system: follow Buyer’s requirement
Temperature in production area must be >=200C
Win speed <=.4m/s
Lighting source in working floor from 70->120lux
Inspection area >=100 lux
Noise range: <=90db
Dust: <= 6,0 mg/m3
Poison gas <=.1%
Water source for drinking: should be met the test at Pasteur Institute
Built up environment management system
Declared environment management policy
Periodically assess environment management system and take action to improve the pending points to ensure it meets environment set requirement
2.1.6 Factory Quality organization chart
Trang 226
Figure 4 : QA organization chart
We can see from above chart, QA and QC teams are divided and leaded by different managers who report to Mr Kwon, General Manager Overall, investment for the quality execution manpower is quite good in this factory
2.1.7 Internal audit procedures:
Figure 5: Internal audit flows
Comments: Choishins(Vina) is apparel manufacturer for different retailer brands, he has his own quality management system and it is not accredited by third party Quality team
is separated from Production Section and it is leading by General Director, Mr Kwon There are two independent teams of QC and QA within the Quality Section QC team is
Trang 237
in charged by Mr Nhut - QC Manager and QA team is leading by Ms Anita - QA Manager
2.2 Introduce about manufacturing flow:
The research is conducted in garment factory whose major products are fashion top and dress in various order size The factory consists of central cutting department, 21 independent sewing lines and centralized finishing and packing Once fabric received, factory conduct inspection randomly at 10% in the meantime, fabric shrinkage, shade also check in prior of cutting Factory has relaxation area and fabric is relaxed 24 hours
in prior of cutting During spreading and cutting, there are 2 QCs to check spreading quality as well as cut panel accuracy before send them to fusing Before sending the panel
to sewing line, QC also checks physical defect Generally, operators are responsible for the quality of individual work, after that there is quality check at the end of each section
so that there should not be any defective parts passed to the next docks
Sewing line once received the panels from cutting, they start marking and input for sewing One inline QC to randomly check the quality of each operation daily Garment after finished sewing, endline QC checks the physical defect, report is signed daily one time The current finishing section is separated with sewing lines Then the garment after inspected by endline QC is put on a trolley and there is one staff to collect the garment hourly and move to ironing section If the Work in Process(WIP) in ironing section is too much then garment is temporarily put in one place and send to pressing table gradually until complete
Garment after ironed, there is one final QC per each ironing table to check the appearance again before passing the garment to hangtag attachment etc
Overall, Choishins( Vina) Manufacturing Flows is running smoothly but there is some points that need to be adjusted to achieve better quality ,efficiency as well as manpower
We will discuss this matter later in the next chapter
Trang 248
Figure 6: Factory quality flow chart which is updated on May 22nd ,2017
2.2.1 Fabric and Trim:
Once received the fabric and trim from suppliers, factory unloads it from containers and put on incoming storage racks, there are 2 QCs to be in charge of fabric inspection, based
on 4 points system to check and reported the inspection result to Warehouse Manager Factory internal requirement that QC should conduct fabric inspection within 7 days after fabric arrived Based on current procedure, once fabric arrived warehouse QC will cut one yard for color, fabric shrinkage and weight checking During fabric inspection, QC
Trang 259
uses fabric swatch which was dated, chopped and compare the shade between being checked fabric against standard QC also checks the shade between left, center, right and two ends of being checked fabric
2.2.2 Sample Room:
Factory has one sample room to make Pre-Production sample, Jump Size Set Sample and TOP sample There is one QC in sample room, she doesn’t know English Sample after finished sewing, QC has checked but there is no inspection record Since sample room does have inspection record, unable to see how rejected rate it is I checked PP checking record from styles that Li& Fung QA handled and found first pass rate is at 96% All machine setting in sample room is being managed by supervisor, no specialized Mechanic for sample room IE person to observe the sample making process, measure and calculate the Sam of bulk
2.2.3 Cutting Section:
2.2.3.1Process Flow Chart in Cutting Section:
In cutting section fabric rolls are inspected as per work order These inspected rolls are segregated on two sides as the quality pass and fail The pass rolls are taken into the next operation whereas the fail rolls returned to store with red tags on them After this, depending upon the order, size and quantity ratio; the spreader spreads the fabric for cutting Depend on the garment construction with fusing or not, the bundles of approximately 20 to 30 pieces are made and fusing is done simultaneously After fusing, all the parts are collected and put in the cutting audit The bundles which pass the cutting audit are forwarded to the sewing section (i.e preparatory section) whereas the fail bundles were re-worked for correction
Trang 2610
Figure 7: Cutting section flows
2.2.3.2 Quality control in Cutting:
Cutting requires skilled employees because failure to properly cut the fabric correctly could result in quality problems with fit and assembly Pieces that are cut too small are incapable of being fixed If a piece is cut too big, then that could potentially affect the size of other pieces The cutter must be meticulous about following the pattern as closely
as possible to insure the quality cutting is done There are 2 QCs in cutting to check the
Trang 2711
cutting accuracy One QC is checking the cutting table for fabric lot using accuracy, ticket#, spreading is acceptable or not Another QC mainly checks cutting accuracy Every bundle after numbering, QC will check randomly top, middle and bottom to insure
it is acceptable Cutting section also arranged 2 QCs to check the physical defects after bundled Report is available All bundles after checked are moved to racks and be waiting
to send to fusing or sewing lines
Cuts Should Be Checked For:
Miscut: Check for miscut or the failure of the Cutter to split the line Tolerance is 1/16” Report all defects for miscuts to Cutting Foreman (Supervisor)
Matching Plies: Check the top ply with the bottom ply to see that they are the same Compare both to a hard pattern or paper maker Tolerance is 1/8” Ragged Cutting: Check for ragged cutting according to the standards of the customer It is a judgment defect It is important on critical parts that if it has
to be re-cut then it is a defect
Notches: Check the notch location by placing the pattern over the top ply Any critical notch missing needs to be checked 100% Tolerance is 1/8” 10% of bundles in a cut should be inspected
2.2.4 Sewing Section:
This section consists of 20 sewing lines and each line has 30 sewing operators to make one full garment The machines are kept in single straight line according to the operation sequence The final garment from last operation is fully checked and corrected immediately for any defects WIP movement inside the assembly is made by the help of work aids attached with each machine The operator, after completing his (her) operation forwards the semi-finished garments to the next machine There is one inline QC per line and only randomly checks the critical operations After the garments completely sewn, there is 2 endline QCs to check the whole garments for physical defects Found the QC report is not updated daily one time by the end of the day with signature of supervisor and QC Checked garments then are put into a trolley to move to finishing section for ironing
Trang 2812

Figure 8: Sewing Flows
2.2.4.2 Sewing Line Quality Control:
Factory has quality control procedure in place Quality procedure is posted in from of
QC table for both worker and QC references
QC Inline randomly picks up the garments, write the report daily However, it is not detailed enough as it does not reflect each operator’s performance
For the QC arrangement, factory arranges 2 endline QCs per line QC endline checks 100% output from sewing, if it is acceptable, then garment is put into a trolley to move
to finishing section for pressing all defects found is recorded into provided check sheet Report is reviewed daily by supervisor but there is no summary how many checked, what
is defect percentage etc
Trang 2913
Figure 9: quality control flows in sewing line
Operator monthly performance:
Factory has performance record monthly, supervisor fulfill the performance record in which mention worker competences of the workers i.e quality of work, quantity, adaptability but this appraisal is very impulsive as it doesn’t lean on any written data
2.2.5 Manufacturing flow in finishing section:
2.2.5.1 Manufacturing flow:
After receiving the garment from endline QC, there is one finishing staff to put the garments on rack for ironing Totally 20 pressing tables in finishing section Ironed garments then moving to finishing QC table for checking in prior passing to ticketing, folding and polybag area
Trang 3014
Figure 10: manufacturing flows in Finishing section
All pieces that well polybagged is passed through metal detector Then it is put on the rack and have packing staffs to randomly check the packing accuracy in prior of packing into the carton
2.2.5.2 Quality control in finishing section:
Garments after pressed, factory arranged QC to check appearance 100% before packing Finishing QC daily measures each size 3 garments, to ensure the garments are meet buyer
‘s given spec Record is available but no summary
Factory also have QA to randomly check the garments that QC inspected and QA also checks the garment after hangtagged, polybagged to make sure it is correct as order requirement before cartoning
Trang 3115
Factory has a QA team specialized in pre-final audit after garments are packed at 80%
If it is passed then QA offers that order for Buyer inspection before shipment Depends
on each buyer’s AQL standard, factory QA currently is using the same standard for final audit
pre-2.2.5.3 Pre-final Team:
Table 1: Pre-final QA name list
From above table, we can see the QA name and which buyer they are assigned to look after For Express, my account and production is running in factory with high volume,
it is required 2 QAs
CHOISHINS(VINA)
In this Chapter, I firstly use the benchmark of Quality Management Maturity check sheet
to capture the quality system maturity of Choishins(Vina) Collect all data from different department to see how effectiveness of factory performance is After that compare factory’s TQM practice against TQM’s element and find out the areas needed to improve For production execution, I used the TQM’s simple tools i.e: check sheet to collect the data from cutting to finishing, analyse and find out the root causes for further improvement actions in Part II of the report
3.1 Defining the Quality Management System maturity level:
Trang 3216
To understanding of the maturity level of organization structure, procedure, process, and resources dedicated to ensure that their products and services satisfy their customers ‘s expectation Dale and Lascelles’(1997) six-level categorization model provide a simple tool for evaluating and understanding the current organizational situation in reference to the degree of maturity of its Quality Management System This model identifies six levels in the adoption of Total Quality Management Principles, which can be used as a platform for performing the assessment Based on this model, the six level of categories
an organization may fall under are (1) uncommitted, (2)drifter, (3) tool pusher, (4) improver, (5) award winners and (6) world class
Figure 11: Illustration of six-level categorization model of Dale and Lascelles (1997) Based on Maturity assessment table, if factory gets score over 4 then it belongs to Tool Pusher Level, score from 3.99-> 3, it belong to Improver Level, score from 2.99 ->2 belonged to Award Winner and score under 2 it should be World Class Level Please kindly refer to below interpretation
3.2 Maturity Diagnostic Instrument Interpretation:
An important consideration is diagnosis made based upon the data interpretation Dale and Lascelles(1997) recognize that some organizations may fall midway between some
of categories, while other may display hydric quality structures, procedures, processes, and resources found into two or more groups Defining a specific category based on the highest score will provide a general overview of QMS status However, a simple but more meaningful diagnosis would be to assess the amount of variance for each of the 84 subcategories in relation to score of 4, which is the neutral point Scores above 4 would indicate a problem with a specific quality process or practice The closer the score is to

Table 3: Maturity assessment score table of Choishins(Vina)
Based on assessment scores, factory got 3.95 points and it belonged to level 3-Tool Pusher Level And according to interpretation of 6 levels of TQM adoption theory (Managing Quality- page 118-edited by Barrie G Dale, Ton Vander Wiele and Jos Van Iwaarden, Blackwell Publishing):
CEO doesn’t have long term TQM plan
Company have met quality standard of one of major Purchaser
Quality mindset is there but not all member of Senior Managemnt is committed to TQM
Have tendency to delegate TQM responsibility to quality department
Trang 3923
Middle management may say all right thing but they remain unconvinced
in their own mind of TQM value In their area of responsibility, they give priority to system and technical which they consider will have more short term impact than TQM
Continuous improvement efforts is only concentrated in production floor With other departments remaining less involved in improvement efforts Quality department is main driving force of improvement process
A certain amount of inter-departmental/functional friction and lack of communication is like to be evident
Focus of quality control is for what exist now, not for future
Meeting output target is the key priority of majority managers with confliction between production section, operation and quality assurance department
Short term result regarding product output and quality are expected, resulting in reactive problem solving and a neglect of long term, root cause, process improvement action
There are repeated claims from some parts of organization that TQM is not working with a tendency to dwell on old practices as being more effective
3.4 TQM practices against TQM ‘s Elements:
TQM Principle Current Status
Leadership Miscommunication between levels of company is still happening
Many activities within organization is not evaluated
Lacking of motivation to all level of staffs toward company objectives, goals
Customer
Focus
The goal of customer satisfaction is not incorporated in planning processes Customer requirements are not identified as the 1st step of quality strategy planning
Involvement of
People
Quality knowledge of employee is very limited, they only know inspection based on quality control, no idea about quality tools, awareness on quality is low
All levels of team have less idea about TQM
Awareness of quality ownership from operators is limited,
Trang 40by inspectors, they will be coordinated to fix it
Concept of continuous improvement is not in practice even there is
no goal for improvement
Mutually
beneficial
supplier
relationships
No monitoring supplier’s quality performance Don’t focus to build
up long term trust-based relationship with suppliers
