    20 Ways to Improve Productivity in Garment

    Production

    Higher productivity brings higher margin in a business. And increment in Productivity level

    reduces garment manufacturing cost. Hence factory can make more profit through productivity

    improvement.

    In this article top 20 ways have been discussed

    that will certainly help factories to boost up current labor productivity. All the means that had

    been explained here can be implemented as because most of these are at your reach. Machine

    productivity as well as labor productivity increases when a factory produces more pieces by the

    existing resources (Manpower, time and machinery).

    When I look into the processes and operations during my visit to factories, I find improvement

    potential is there in every area. Initially, you may not be able to find and measure potential

    areas. Still you can improve productivity by applying some of the following steps.

    I have mentioned 20 ways where you can focus and start working on improving productivity. To

    provide you knowledge in details few links have been given for your further reading in some of

    the steps. Most of the tips mentioned in this article are mainly on time saving tips, discipline

    and proper planning. To get excellent result you may need external recommendation and

    support but without the external help you can surely get measurable improvement once you

    start your journey.

    One thing you need to understand that application of the following steps will vary based on

    production systems. I have written this article focusing on progressive bundle system.

    If you are new in the productivity discussion, before stepping into following steps, I will suggestyou readHow to measure labor productivitythat will help you to understand following

    discussions.

    1. Conducting motion study and correcting faulty motions: There is a saying Even best can be

    improved. So go to Gemba (sewing floor) and look for operators working method and

    movements. Prepare a check list for good methods and movements. At time of motion study

    observe operators movement and compare with you checklist. If you found wrong movements

    is used by operator or unnecessarily extra movement is present in the operation cycle correct

    it. If needed deskill operator. By doing this you can reduce operation cycle time and canimprove labor productivity up to 100%* in individual operations (*in 20% of the total

    operations as per Paretos 80-20 Principle).

    2. Hourly operator capacity check:Employ work study personnel (if you dont have) and start

    checking operator capacity hourly or bi-hourly. Compare actual operators hourly production

    with their capacity. If production is less then question them why? It helps in two waysfirst,

    when operators capacity is checked at regular interval they will be under pressure. Secondly,

    work study personnel start thinking on methods how cycle time can be reduced. Using the

    capacity data, you can move ahead in balancing the line.

    3. Conduct R&D for the garment:A non-value added (NVA) process but having a strong

    Research and Development (R&D) team in the factory brings lot of benefits. R&D can be taken

    as preparation stage for the bulk production. This department does sample production and look

    into potentially critical operations, plan for requirement of special equipment, advice changes

    in terms of construction without changing styling. E.g. if an operation contains some raw

    stitches, which doesnt affect the final look of the garment, then that operation can be avoided

    if possible to save time. They plan for skill requirement for the operations. As a result

    production runs without any break or with less no. of breaks. As it reduces the chance of break

    in production for unnecessary reasons, line productivity doesnt come down.

    4. Use best possible line layout:Line layout means placing of machines and centre table (trolley

    with wheel) as per style requirement. The main purpose of choosing a better layout is to reduce

    transportation time in the line as much as possible. A stable line is not a good idea if you

    produce multiple products in a same line. A straight assembly line with centre table at left side

    is good for a product that has no preparatory work and individual operation SAM is nearby the

    pitch time. When a style includes lot of preparatory work (for garment parts), it is better to

    make garment parts in sections and assemble them later. If possible use overhead

    transportation system.

    5. Scientific work station layout: The workstation layout defines from where an operator will

    pick up work (garment components) and where she will dispose stitched garment. A scientific

    layout is defined as minimum reach for picking up and dispose of components. Every

    components and tools (trimmer) must be kept within operator reach. During workstation

    designing, engineering must follow key principles.

    Components to be worked on should be positioned as near to the needle as possible.

    Direction of the components where it positioned on the table or track should be such

    way that during moving component to the needle point does not need to turn it.

    Placing of work at the same plane of the machine table so that operator can easily slide

    it to needle point.

    The purpose of designing a good workstation layout is to minimize the material handling time

    as much as possible. Thus you can reduce operation cycle time. Secondary benefit of good

    workstation is operators can work at same pace without fatigue. When designing a workstation

    layout dont forget to consider ergonomics.

    6. Reduce line setting time:It have been observed that a line reaches at its pick productivity

    level on day 6-7 after loading of an order. The time lost in the initial days (learning curve) brings

    down the average labor productivity for whole style. Reason - lot of time is lost during setting of

    the line for a new style. This reduces overall machine productivity and line efficiency. So to

    maintain line productivity level you have to work on minimising line setting time or throughput

    time. To reduce the line setting time, engineers have to study the garment thoroughly, prepare

    operation bulletin with machine requirement and machine layout plan prior to feeding cuttings

    to the line. Read another article to knowhow to reduce line setting time. Engineers need to

    coordinate with line supervisors and maintenance department with their plans and

    requirements. This will help supervisors and maintenance department to be pro-active in

    arranging required resources.

    7. Improve line balancing:Purpose of balancing a line is to reduce operators idle time or

    maximize operator utilization. In a balanced line work will flow smoothly and no time will be

    lost in waiting for work. At time of line setting select operators for the operation matching

    operator skill history and skill required. Following this method you will select highly skilled

    operators for higher work content operations. Once line is set conduct capacity study at a

    regular interval. Usepitch diagram method to find bottlenecks inside the line. You have to think

    how you willminimize WIP level at bottleneck operations. Read another article online

    balancing for guidelines. Once you start increasing operator utilization through line balancing

    you will get extra pieces from the same resources in defined time.

    Even a well managed factory can improve productivity by 22% thorough line balancing reportedby Md. Rezaul Hasan Shumon, Kazi Ar if-Uz-Zaman, and Azizur Rahman in aResearch

    Study Productivity Improvement through Line Balancing in Apparel Industries.

    8. Use work aids, attachments, guides, correct pressure foots and folders:These are some

    kinds of time saving devises that facilitate operator to perform their work effectively with less

    effort. If work aids are used effectively operation cycle time can be reduced many fold than

    existing cycle time. In new and small factories where there is no experienced technical person

    (maintenance, IE personnel or production manager) generally not aware about the usage and

    availability of work aids. So their operators sew garment free hand. Labor productivity iscomparably higher for the factories that widely use work aids than those who do not use work

    aids for the similar products. Folders and attachments are also very helpful in producing

    consistent stitching quality. On the other hand work aids, guides and fixtures reduce operators

    movement and weight lifting. During my research study I college I had improved labor

    productivity up to 18.03% using work aids in various operations.

    9. Continuous feeding to the sewing line:It is not a fault of production department if they did

    not get cuttings to sew. All plans and efforts towards productivity will fail if line is not been fed

    continuously. No feeding or irregular feeding is one of the top reasons for lower productivity

    in poorly managed factory. Poor production plan, wrong selection product mix in seasons and

    ineffective cutting department are the reasons that stop continuous feeding. Once operators

    get the rhythm, they should be given non-stop feeding until style changeover to keep up the

    productivity. If you know there is unavailability of cutting in near future then plan accordingly

    and dont call all operators for that duration.

    10. Feed fault free and precise cutting to line:Stop cutting and trimming of extra fabric from

    cut components by operators. If your cutter does not able to provide precise cutting s/he

    should be trained. But faulty cutting dont be fed. When operatorscut fabric he performs

    additional task in the operation cycle time. If in some cases trimming is intended then that task

    must be included in total work content. Otherwise you will get wrong (less) efficiency for the

    operator. Secondly, cuttings withfabric defects,pattern problem are issued to sewing line. As a

    result line produces defective garments. Alteration and repair work for defective garments

    reduces labor productivity.

    11. Training for Line supervisors:Line supervisors are shop floor managers. So each supervisor

    must be trained with fundamental management skills and communication skill. Still in most of

    the supervisors in Indian factories are raised from tailors. They dont acquire technical

    qualification in supervising. But their main job is providing instruction, transferring information.

    For which communication skill training is required for supervisors. Secondly, supervisor shouldunderstand the fundamental of industrial engineering like operation bulletin, skill matrix,

    workstation layout, movement, capacity study and theoretical line balancing etc. If they

    understood these, they can help engineers or work study boys to improve line performance.

    The above training will bring changes in managing and controlling the lines and will improve

    labor productivity.

    12. Training to sewing operators:Operators are main resources in the apparel manufacturing.

    They are most valuable resource to the company. So, factory must work on developing

    operator skill where required. Training is not cost but an investment said by many experts.Production from an operator depends on his skill level to the task. A low skilled operator will

    consume higher resources (time) and give less output. You will find quality related issues with

    low skilled and untrained operators. As the skill level of the operators is increased through

    training lines output will improve. Training does mean lot of time and money. Training should

    be given only on specific tasks that will be performed by the operator. Pauls article systematic

    training for apparel industry operatorsan introduction is very helpful in this regard.

    13. Setting individual operator target: Instead of giving equal target to all operators working in

    a line, give individual target as per operators skill level and capacity. Set an achievable target for

    each operator so that they would try to reach the target. This will help improving operators

    individual efficiency. Use tricks for increasing target step by step. Take care of the operators

    who are under target. They may need skill training. Go back to point#12. Training for sewing

    operators.

    14. Eliminate loss time andoff-standard time:Utilize operators time as much as you can.

    There is no better alternative than just stopping operators sitting idle to improve operator

    productivity. Non productive time such as waiting for work, machine breakdown, power failure

    and repair work kill your productivity. Start eliminating non-productive time as much as

    possible. To start work on this point you have to track off-standard or non-productive time data

    according to different categories. Once you have the analysis and Pareto of non-productive

    time you can think and plan on reducing it.

    15. Real time shop floor data tracking system:For the continuous improvement and prompt

    action on failure you need information from the shop floor as fast as possible. Important

    information needed such as hourly production, line balancing, WIP, tracking bundles and

    quality performance of the line. If corrective action is not been taken early problem may

    increase as time goes. So RFID based real time systems are helping in providing shop floor

    information within second. With Leadtec system Joshep Abboud increased its total productivity

    more than 40% (refer to the following case study link). This system is quite costlier at this time.But as perpublished case studies ROI (12-18 months) of this RFID based real time system is not

    bad.

    16. Using auto trimmer sewing machine (UBT): Just think how many pieces an operator is

    producing in a day? Each time an operator trims thread using a trimmer or scissors consume

    time minimum 50 TMU or 2 Seconds (approx). A rough estimate, in a day operator will lose

    about 20 minutes just in thread cutting. In an operation of 0.5 SAM, operator can make 40 extra

    pieces. Even machine without auto trimmer consumes more sewing thread. Those who use

    heavy (half kilogram weight) scissor may start using hand trimmer.

    17. Installing better equipment:A low performing machine is not acceptable where some of

    your good machines are idle in the same building. Use the best of your resources. If machines

    or equipment dont perform well operator motivation goes down. Repetitive breakdown of

    machines increase the loss time and bring down overall line efficiency and labor productivity. I

    have seen lines where UBT machine is used in long seam operations and comparably lower

    work content. On the other hand where shorter seams are being stitched, most of the time

    spent in thread trimming for taking out work from the needle, normal lock stitch sewing

    machine are used.

    18. Inline quality inspection at regular interval:Traffic light system is the most effective

    inspection tool to reduce defect generation at source. Less number of defective seam is made

    less the time will be lost in repairing it. Inline checking system will alert operators in

    concentrating their job. It also helps in other way. May be at the start of the style an operator

    not understood the specification, an interaction with quality inspector will make an operator

    clear about the quality requirement. Poorly managed factory loses productivity up to 10% due

    to repair and reject as mentioned by Dr. Bheda in his articleProductivity in Apparel

    Manufacturing.

    19. Operator motivation:Operators will is the most crucial part in productivity improvement.

    If they are motivated, they will put enough efforts on the work. Employee motivation generally

    depends on various factors like work culture, HR policies, bonus on extra effort or achieving

    target. In garment manufacturing operators motivation come through extra money. Operator

    7/7

    motivation can be improve by sharing certain percentage of you profit made from operators

    extra effort.

    20. Plan for operators Incentive scheme: Paul Collyer, British expert says In British factories,

    in a non incentive environment factory can reach up to 80% efficiency level and if managerexpect more than that they had to provide incentive to operators as well as to the supporting

    team. Ifwe look into Asian factories, in a non incentive environment factories find it is very

    difficult to reach up to 40% efficiency. You can see the potential efficiency that can be

    converted in money.

    You need to understand that employees come for work in your organization for money. Initially

    you may think that an incentive scheme may reduce your profit. But in real it works in opposite

    direction, provided that incentive system is fair for the workers and has been implemented

    intelligently. I have seen factories where operator efficiency reaches up to 76% from 45% afterimplementation of incentive scheme. An incentive scheme will give lot of other benefits in

    return as a byproduct. An incentive scheme designed with multiple parameters may bring

    discipline on the shop floor. As operators give extra effort to the work, efficiency as well as

    productivity of the operator increases.
