TQM and Details of TQM in Apparels

 

TQM

There are many approaches in the business domain in order to achieve and exceed the quality expectations of the clients.

For this, most companies integrate all quality-related processes and functions together and control it from a central point

 

The Origin

The origin of the TQM goes back to the time of the First World War. During the World War I, there have been a number of quality assurance initiatives taken place due to the large-scale manufacturing required for war efforts.

The military fronts could not afford poor quality products and suffered heavy losses due to the poor quality. Therefore, different stakeholders of the war initiated efforts to enhance the manufacturing quality.

First of all, quality inspectors were introduced to the assembly lines in order to inspect the quality. Products below certain quality standard were sent back for fixing.

Even after World War I ended, the practice of using quality inspectors continued in manufacturing plants. By this time, quality inspectors had more time in their hands to perform their job.

Therefore, they came up with different ideas of assuring the quality. These efforts led to the origin of Statistical Quality Control (SQC). Sampling was used in this method for quality control.

As a result, quality assurance and quality control cost reduced, as inspection of every production item was need in this approach.

During the post World War II era, Japanese manufacturers produced poor quality products. As a result of this, Japanese government invited Dr. Deming to train Japanese engineers in quality assurance processes.

By 1950, quality control and quality assurance were core components of Japanese manufacturing processes and employees of all levels within the company adopted these quality processes.

By 1970s, the idea of total quality started surfacing. In this approach, all the employees (from CEO to the lowest level) were supposed to take responsibility of implementing quality processes for their respective work areas.

In addition, it was their responsibility to quality control, their own work.

Basic Principles of TQM

In TQM, the processes and initiatives that produce products or services are thoroughly managed. By this way of managing, process variations are minimized, so the end product or the service will have a predictable quality level.

Following are the key principles used in TQM:

·       Top management – The upper management is the driving force behind TQM. The upper management bears the responsibility of creating an environment to rollout TQM concepts and practices.

·       Training needs – When a TQM rollout is due, all the employees of the company need to go through a proper cycle of training. Once the TQM implementation starts, the employees should go through regular trainings and certification process.

·       Customer orientation – The quality improvements should ultimately target improving the customer satisfaction. For this, the company can conduct surveys and feedback forums for gathering customer satisfaction and feedback information.

·       Involvement of employees – Pro-activeness of employees is the main contribution from the staff. The TQM environment should make sure that the employees who are proactive are rewarded appropriately.

·       Techniques and tools – Use of techniques and tools suitable for the company is one of the main factors of TQM.

·       Corporate culture – The corporate culture should be such that it facilitates the employees with the tools and techniques where the employees can work towards achieving higher quality.

·       Continues improvements – TQM implementation is not a one time exercise. As long as the company practices TQM, the TQM process should be improved continuously.

The Cost

Some companies are under the impression that the cost of TQM is higher than the benefits it offers. This might be true for the companies in small scale, trying to do everything that comes under TQM.

https://www.academyeurope.org/wp-content/uploads/2021/04/339-7-300x100.jpg

According to a number of industrial researches, the total cost of poor quality for a company always exceeds the cost of implementing TQM.

In addition, there is a hidden cost for the companies with poor quality products such as handling customer complaints, re-shipping, and the overall brand name damage.

PRIMARY ELEMENTS OF TQM

1.     Customer-focused: The customer ultimately determines the level of quality. No matter what an organization does to foster quality improvement—training employees, integrating quality into the design process, or upgrading computers or software—the customer determines whether the efforts were worthwhile.

2.     Total employee involvement: All employees participate in working toward common goals. Total employee commitment can only be obtained after fear has been driven from the workplace, when empowerment has occurred, and when management has provided the proper environment. High-performance work systems integrate continuous improvement efforts with normal business operations. Self-managed work teams are one form of empowerment.

3.     Process-centered: A fundamental part of TQM is a focus on process thinking. A process is a series of steps that take inputs from suppliers (internal or external) and transforms them into outputs that are delivered to customers (internal or external). The steps required to carry out the process are defined, and performance measures are continuously monitored in order to detect unexpected variation.

4.     Integrated system: Although an organization may consist of many different functional specialties often organized into vertically structured departments, it is the horizontal processes interconnecting these functions that are the focus of TQM.

1.      

·       Micro-processes add up to larger processes, and all processes aggregate into the business processes required for defining and implementing strategy. Everyone must understand the vision, mission, and guiding principles as well as the quality policies, objectives, and critical processes of the organization. Business performance must be monitored and communicated continuously.

·       An integrated business system may be modeled after the Baldrige Award criteria and/or incorporate the ISO 9000 standards. Every organization has a unique work culture, and it is virtually impossible to achieve excellence in its products and services unless a good quality culture has been fostered. Thus, an integrated system connects business improvement elements in an attempt to continually improve and exceed the expectations of customers, employees, and other stakeholders.

5.     Strategic and systematic approach: A critical part of the management of quality is the strategic and systematic approach to achieving an organization’s vision, mission, and goals. This process, called strategic planning or strategic management, includes the formulation of a strategic plan that integrates quality as a core component.

6.     Continual improvement: A large aspect of TQM is continual process improvement. Continual improvement drives an organization to be both analytical and creative in finding ways to become more competitive and more effective at meeting stakeholder expectations.

7.     Fact-based decision making: In order to know how well an organization is performing, data on performance measures are necessary. TQM requires that an organization continually collect and analyze data in order to improve decision making accuracy, achieve consensus, and allow prediction based on past history.

8.     Communications: During times of organizational change, as well as part of day-to-day operation, effective communications plays a large part in maintaining morale and in motivating employees at all levels. Communications involve strategies, method, and timeliness.

 TOTAL QUALITY MANAGEMENT SYSTEM STRATEGIES

Imprints of TQM concepts can be found in modern approaches to quality management, such as the Malcolm Baldrige National Quality Award (MBNQA) criteria, ISO 9001Six Sigma and lean manufacturing, as well as the examples below.

Total Quality Management (TQM) Implementation Strategies
Total Quality Management (TQM) Implementation Strategies

Strategy 1: The TQM element approach

The TQM element approach takes key business processes and/or organizational units and uses the tools of TQM to foster improvements. This method was widely used in the early 1980s as companies tried to implement parts of TQM as they learned them. Examples of this approach include quality circles, statistical process control, Taguchi methods, and quality function deployment.

Strategy 2: The guru approach

The guru approach uses the teachings and writings of one or more of the leading quality thinkers as a guide against which to determine where the organization has deficiencies. The organization makes appropriate changes to remedy those deficiencies. For example, managers might study Deming’s 14 points or attend the Crosby College. Afterward, they would work on implementing the approach learned.

Strategy 3: The organization model approach

In this approach, individuals or teams visit organizations that have taken a leadership role in TQM and determine their processes and reasons for success. They then integrate these ideas with their own ideas to develop an organizational model adapted for their specific organization. This method was used widely in the late 1980s and is exemplified by the initial recipients of the Malcolm Baldrige National Quality Award.

Strategy 4: The Japanese total quality approach

Organizations using the Japanese total quality approach examine the detailed implementation techniques and strategies employed by Deming Prize-winning companies and use this experience to develop a long-range master plan for in-house use. This approach was used by Florida Power and Light—among others—to implement TQM and to compete for, and win, the Deming Prize.

Strategy 5: The award criteria approach

When using this model, an organization uses the criteria of a quality award (e.g., the Deming Prize, the European Quality Award, or the Malcolm Baldrige National Quality Award), to identify areas for improvement. Under this approach, TQM implementation focuses on meeting specific award criteria.

Although some argue that this is not an appropriate use of award criteria, some organizations do use this approach and it can result in improvement.

Basic idea of Quality and QMS part and how to face the interview with other company

1.     What is Quality?

Answer:

In short, Quality is customer satisfaction. Or Quality is the fitness for use.

Quality is the ability of a product to meet customer satisfaction for that product.

 

Importance of quality in apparels: The garments manufacturer is supplier of buyer or retailer. Buyer analysis the users demands & provide requirement to the supplier before ordering their desire products. The ultimate considerable thing is users’ satisfaction & keep up the brand reputation. Wearer ever don’t want to buy poor quality products if buy anyhow negative concepts can be born in the wearer mind on that brand & fall down the brand reputation. No brand wants to reduce their reputation. So, buyer or retailer do not purchase any product except their desire quality.

 

So, there is no way to ignore quality. Quality must be controlled during operation whether it is done by the operators, supervisors, pressing man, packers, checker, or inspector etc. In case the quality of product not being controlled during operation then it will affect following point –

·       High alter & DHU percentage

·       Increase rejection percentage

·       Increase cost for rework

·       Increase working hour

·       Delay to complete production

·       More shocking thing is Factory may lose customers.

·       Ultimately cost of manufacture will increase

So, Factory must need an appropriate quality control team who can run the process with buyer requirement to achieve customer satisfaction & keep existence.

There are four types of inspection –

Inspection: Inspection is a practical method of selecting a certain quantity of Raw Materials or Finished Goods in a certain way before finally selecting any Raw Materials or Finished Goods.

 

A.      Pre-production Inspection:

Pre-production is done before the bulk starts. It is done to check for final verification & meet customer requirement of bulk fabric, trims & accessories, styling, manufacturing way, washing, workmanship, measurement etc. against approved sample & wash standard.

 

B.      Initial inspection:

Initial inspection is done at the starts of production when the first output come out the end line quality table. There raise the possible discrepancies, variation & take necessary action to meet customer requirement for specific style. It’s a preliminary stage of styling details, general appearance, workmanship, measurement, fabric & trim component etc.  Whatever discrepancies identify initially could take action & get solution during starts of bulk production.

 

C.      During production inspection:

During production inspection is done during production to ensure initial discrepancies have been corrected and rectified. All the initial discrepancies should fix at the same time & follow by GPQ or line QA during bulk production.

 

D.     Final Random inspection:

Final random inspection is done when the quantity of an order has been enclosed completely. As per the selected AQL from customer sample quantity should be select & inspect. Also, result will be considered as per the AQL system.

 

9.     What is the difference between Defect & Defective?

Answer:

Defect: Any kind of alter is defect.

Defective: Garments that has one or more defects is called defective garments.

 

10. What is the difference between QA & QC?

Answer:

The flow chart shows all process accordingly & process are connected arrow. Also, it shows conditional process if not happen any problem, then need to follow accordingly else need to follow the conditional process. It helps to keep our process on right track.

 

C.    Pareto chart: A pareto chart is a bar graph & it consists with bars. Both bars show individual values. Left vertical bar indicate the number of discrepancies / defects found & right vertical bar indicate the cumulative percentage of total discrepancies / defects. In quality controls, it can be used to as a source of top defect, top complaint from buyer etc.

 

D.    Histogram: Histogram is a graphical chart. It consists of vertical bars of different height & each bar indicate a different group of data. It shows continuous data of similar category. It helps to summarize data & represent in bar & indicate in which are need pay attention.

 

E.    Check sheet / Tally sheet: Check sheet is a simple form to collect data in real time where the data is occurred. It is designed to keep data accurately, easily & efficiently. It can be either quantitative or qualitative. When the data is quantitative the check sheet is also called a tally sheet. We can computerize, analysis from this raw data for further action.

finding better ways to deliver right valuable product to the customer.

 

B.    Value stream mapping:

C.    Create flow:

D.    Pull system:

E.    Perfection:

 

·       8 wastages of Lean: -

 

A.    Unnecessary Transportation: Transportation means any tools or materials that can be required carrying by hand or vehicle. Transition waste increases when you need to move things from here to there. It can be happened for poor lay out, poor process planning, Incorrect process flow etc. Transportation increase costs, needs time & product or tools may damage.

 

B.    Over defects: Defects is a wastage in garments. It increases lead time, Rework costs, material consumption & sometimes we can face delay of shipment which is threat for factory.

 

C.    Over Production: It can happen when operator produced blindly but output cannot be processed due to receivers are not ready or don’t need this production at this time.

 

D.    Waiting: Sometimes we can observe works are interrupted due to material missing, waiting for approval, Machine problem, Operation stops for defects etc. reasons. Factory can overcome this problem by well-organized everything.

 

E.    Excess Inventory: Order too may & earlier accessories from supplier need large space in warehouse then maintain warehouse become tough & cost can be increased.

 

F.     Excess Movement: If a process needs extra employee for extra steps, it is just waste of money & time.

 

G.    Over Procedure: Over procedure can happen due to poor designed of process & document. As a result, there can be happen over procedure like multiple variation of one task, several signature, entry duplicate data, process more goods then required.

 

H.    Unused talent: This is not related to process issue. Not utilize exist talent can be called as a waste. A factory can step their desire position by utilize talent. If assign employee to wrong task or he don’t get chance it is not possible to work out his talent.

 

 

16. What is DMAIC?

Answer:

DMAIC stand for Define, Measure, Analyze, Improve & Control. It’s a methodology that used to improve existing process.

 

Define: Before we start work on a problem, we must know the definition of that problem, why we are working on it, where is the focusing area, what is the scope etc. All of these are in define phase.

 

Measure: The measure phase is about ensure correct data. We make decision based on facts & data. We must ensure that we are taking decision based on correct data otherwise we could make incorrect decision that will effect on our whole process.

 

Analyze: The collected data and process map to determine root causes of defects and opportunities for improvement.

 

Improve: Improve focus on getting the best potential solution from more solution to solve the root cause of the problem.

 

Control: Control is about ensuring that the solution is sustainable in the long time.

There are various types of fabric inspection system such as –

A.    2.5 fabric inspection system.

B.    4-point fabric inspection system.

C.    10-point fabric inspection system

 

30. Describe 4-point fabric inspection system?

Answer:

In this system the quality level of fabric is determined based on a certain number of penalty points for every 100 yards of cloth.

 

এই সিস্টেম প্রতি ১০০ গজ কাপড়ের জন্য নির্দিষ্ট সংখ্যক penalty points এর ভিত্তিতে কাপড়ের quality level নির্ধারন করা হয়

 

4-point fabric inspection system are the most used in the garments industries which is performed following ASTM D5430-93.

 

H&M Requirements overview:

 

H&M prefer 10% fabric visual inspection of bulk fabric. If fabric quantity below 1000m then 100% should be inspected. If found average defect & inspection get fail as per requirement an additional 15% must be inspected. If fabric fails again, 100% of quantity should be inspected or reject the quantity. Two inspectors could inspect maximum 2 hours continuously. After that either there should be break schedule or perform by another two inspectors for next two hours.

 

       General requirements of fabric inspection area:

 

A.    In the inspection area should be proper lighting as per customer requirement.

B.    The frame of the fabric inspection machine through which the fabric travels should be bent at an angle of 45 to 60 degrees.

C.    In the top of inspection table there should be two F96 fluorescent light & sometimes can be needed to use back light under the table

D.    Fabric inspection machine speed should not be more than 15 meter per minutes.

E.    All defects found during inspection must be documented clearly.

F.     Inspection reports must be kept at least 6 months

 

Bowing:

Bowing is a common fabric defect. When the weft yarn of the fabric gets displayed from a line to the fabric selvedge then it’s called bowing defect.

Skew:

Skew is a common fabric defect. When the weft yarn of the fabric gets angularly displaced from a line to the fabric side or edge then it’s called skew defect.

 

                    Purpose of inspection:

A.    Find out the defects.

B.    Rectify the defect or defective fabrics.

C.    Grading/Grouping the fabric.

D.    Take decision the fabric acceptable or rejected.

31. Fabric Shrinkage Test system.

Answer:

Fabric shrinkage define as a piece of fabric changes in length or width during the laundry process.

 

·       Once bulk fabric is in house cut specimen from each fabric roll keeping on shrinkage template board.

·       The specimen must be fully relaxed before cut & Specimen should be 50cm X 50cm.

·       Send the specimen for wash.

·       After getting washed specimen measure the difference between before & after wash.

·       Calculate the shrinkage percentage using below mentioned law.

·       Shrinkage acceptable percentage is till 3%.

·       For normal fabric minimum 10% of bulk fabric, Low stretchability fabric minimum 30%, High stretchability fabric 100% of bulk fabric should be tested.

·       When fabric shrinkage exceeds the tolerance or show too high then 100% should be perform 100% test.

Law to calculate shrinkage:

 

Before wash MMT – After wash MMT * 100

                            Before Wash MMT

             *Note: The same way to calculate length & width.

 

32. What is yarn count.

Answer:

Count is a number which indicates the mass per unit length or the length per unit mass of yarn. It also expresses weather the yarn is thick or thin.

 

Another Definition: Count is the mass of a single length of yarn or the length of a single mass.

কাউন্ট হল সুতার একক length এর ভর বা একক ভরের length প্রকাশ করে

 

There are mainly two types of yarn count system –

33. What is GSM.

Answer:

GSM stand for “Gram per square meter” (g/m2).

GSM means the weight in gram per square meter of fabric.

GSM is one of the primary fabric quality parameters. When we need to purchase a fabric or need to get the fabric development done, we must mention your fabric GSM requirement.

GSM value depends on fabric content like cotton, elastane, nylon, spandex etc.

 

GSM inversely proportional to stitch length. If stitch increase than GSM will be increase on                                             the other hand if stitch length decreases than GSM will be decrease. Normal tolerance for GSM is   +/- 3%. So, a 300 GSM material can vary in weight between 291 and 309 GSM.

 

GSM measure steps:

 

A.    Cut the fabric with the GSM cutter (gram per square inch).

B.    Weight the fabric with the electric balance.

C.    The cut sample is 100 sq. cm.

D.    The result is the GSM of that particular fabric.

 

            How to calculate GSM:

A.    Multiply by 100 of Average weight of sample.

 

Ø  Firstly, you have to cut 5pcs swatches by sing GSM cutter from the different parts of fabrics.

Ø  Now, Measure the weight of each cutting swatches with the help of weighing balance in one by one method.

Ø  Calculate the average weight of cutting swatches.

Ø  Now, by multiplying “average cutting swatch weight” with 100, we can easily get the actual fabric’s GSM.

 

Fabric’s GSM = Average cutting swatch weight × 100
