‘Visual Management’ is an important part of lean manufacturing. It
can carry up to 90% information in production floor. Visual management can
convey message more effectively & easily understandable by all. Though It
has positive impact, we sometimes overlooked this tool because of our ignorance
or lack of knowledge. Visual management is a tangible way of communication to
express rules, SOP, performance, standard, warning etc. It requires prior or
less training to implement & follow. In this article it will be discussed
how visual management is important for garments finishing unit. Garments
finishing is one of the important step of completion of product life cycle. Finishing
unit consist of garments checking, measurement follow-up, standard follow-up, trimming
uncut threads, ironing, adding trims & accessories, wrapping, packing,
weighting etc.
Visual Management: A Tool of Lean Management for Garments Finishing Unit
1. To Hang a Layout Diagram/Picture
It is good practice to use same
layout for all lines in finishing unit. Here A layout showing every steps of
garments finishing along with workstation orientation. There must include all
physical variables, structures, length & width, substations, pathway etc. It
is easy to make layout diagram in excel or AutoCAD by keeping measurement. Whenever
a new employee or worker will see the layout, can easily understand the
workflow. Language used in layout can be Bengali or English as per wish. It is
helpful for any kind of technical or compliance audit also. A layout of your
production or finishing floor can easily make first impression better when a
new buyer visits your floor. It is an easy lean tool to make anyone understand
about work activities & discipline.
2. To Do Demarcation
Demarcation is the second step of
visual management. Demarcation is fixing or identifying area for specific work.
Do divide your finishing line is substations. Then fix the area by measuring
& considering ergonomically standard work stations. You can take operators
or workers view while dividing the area. It will add positive value & they
will abide by the rules later. The question may be why this is necessary? It is
necessary to fix work area to make sustainable discipline in finishing floor. No
machine, table, man or accessories will move beyond your demarcation area. It
is another way to eliminate process flow time by irregular flow. Demarcation
can be done using color or different color tiles as per wish.
3. To Attach Identifier Board and KPI Board
After subdividing your work stations, the third step is to make visual boards or stickers for every workstation. Workstation identifier boards must be attached to every workstation. When you will follow it for every line in your finishing floor, it will look like an organized finishing floor. Anyone can understand process flow very easily. During any kind of buyer visit or audit, you will not have to follow them and show them the workstation by telling operation name. Well organized factories follow this visual management to reduce these kinds of micromanaging activities. Don’t think about the monetary value of identifier boards, implement them first & gradually you would see the result. KPI board need to be attached in front of the finishing line. You can add KPI list as per your factory standard. Finishing garments operation breakdown, DHU percentage, daily production & efficiency, attendance & leave status can be added in KPI board. It is good practice to include several departments activities in KPI board like HR, Quality, IE & top management. A well-organized KPI board can save minimum 1hour time. You want to know, how? At morning IE will fill up KPI board with efficiency or bottleneck status, QC will fill defect rate or top defect areas, HR will fill leave or attendance status, the production team will fill plan vs target status etc. These kinds of visual management will help top management to identify any line status at a glance. So why not you are applying it on your floor!
4. To Make Rules, Instructions, and Standardization for Sustain
It is necessary to make visual
management sustainable. For this purpose, some rules & instruction can be
visualized for standardization. It also helps to maintain discipline & in
some cases have direct impact on productivity improvement & defect
reduction. A proper set up of visual management is the first pre-requisite of
lean manufacturing process. It helps to make audit successful, reduce defect
label, maintain HR rules & regulations, workplace standardization &
calm environment.
Visual management helps to identify mistakes, improper orientation, mismanagement & irregularities. Not only for garments finishing unit, visual management is mandatory for all units like cutting, printing, sewing, washing, dyeing, warehouse etc. Office workstation can be properly visualized & it will make your organization a wonder land of lean based organization. Then why not approaching towards this small & continuous improvement? You can easily follow mentioned four steps for any kind of factory or organization from shop floor to workstation.
Industrial Engineering – IE is one of the popular term used in the apparel industry, where this work for optimization of complex process within the industry. Optimization is applicable to men, machine, materials, methods, and monetary resources. Here in this article you will have details of necessary IE terms of apparel industry with examples.
Necessary IE Terms of Apparel Industry
Needed Industrial Engineering (IE) Terms Mostly Used in Apparel Industry
Very basic apparel industrial engineering terms discussed with example for clear understanding. List of terms are:
Standard minute value (SMV)
Efficiency
Line target
CPM & CM
CM/COM/MC
Broad calculation of garments cm
Conventional vs modern profit theory
Cost of making (CM) rule
Work study
Time & motion study
Line balancing
1. Standard Minute Value (SMV)
SMVdefined as the term Standard Minute Value, is mostly used in the garments industry and it is a common measurement calculated by the Industrial Engineer. Generally, SMV indicates the time taken to make garments by the workers using the right types of machinery.
SMV = BASIC TIME + (BASIC TIME × ALLOWANCE)
Suppose to complete an operation, a standard operator takes 1 minute.
We put 15% allowance (Men, M/c & Time)
SMV=1+(1×.15) Min =(1+.15) Min =1.15 Min
GMT SMV is the sum of SMV for all M/c & Manual operation to complete an item
Related Terms of SMV
Standard Operator: For a specific item & style, the potential operator who can give maximum output with the best quality & can improve productivity.
Let’s see an Example for better understanding,
Batsman faces 10 balls to score 5 Runs
Batsman faces 10 balls to score 12 runs
Batsman faces 10 balls to score 10 runs.
Obviously 2nd one is the potential batsman who uses his
Inputs (balls) to get maximum output (Runs)
Pre-defined Conditions: On time input arrival, single piece flow, running m/c conditions, defined quality status, etc. are called pre-defined conditions.
Basic Time: Actual time to complete an operation. In another word, basic time is the pick & drop time including an operation for quality output.
Basic
Time= Pick time + Operation + Drop time;
Result ,
Input=Output with required quality
In a broad sense , a GMT SMV=Sum
of all operation SMV, not SMV of GMT + allowance.
2. Efficiency
Efficiency defined as ‘’The comparison of what is actually produced or performed with what can be achieved with the same consumption of resources (Men, M/c, Material, etc. )’’
Efficiency = Earned Minute/Available Minute
Earned Minute = Production (Pcs) x SMV
Available Minute = Manpower (Helper + Operator) x Working Time (Minute)
Calculation of Efficiency Percent
Suppose any GMT item SMV is 5.5 (For any fixed style SMV always fixed)
We use 22 Manpower(Operator & Helper) to achieve 1500 Pcs for 10 hours working shift
Earned Minute = 1500× 5.5 or 8250 Min
Available Minute = 22× (10×60) or 13200 Min
Efficiency = 8250 Min/13200 Minute or 0.625
Efficiency is expressed as % ,Then Efficiency =(0.625 ×100)% or 62.50%
Efficiency is a ratio, not a number.
Efficiency varies with Lead Time and Quantity. More Lead time & Quantity Increase Efficiency, on the other hand, less lead time tends us to use more MP or time to get the required output, so efficiency reduces.
3. Line Target
Target= (total MP X WH X 60)/SMV
Suppose We have 22 MP for 10 hr .GMT SMV is 5.5
Target =(22 X10 X60)/5.5 =2400 PCs/Hr (That is 100% TGT)
For expected efficiency this 100% Target is multiplied by efficiency to fix Line Target
Line Target =(2400X.625) ; (Lets , we have expected efficiency of 62.5%) =1500 PCs or 150PCs/Hr
4. CPM and CM
CPM Stands for Cost Per Minute which means Cost of every minute of garments sewing operations. To offer the best competitive price to the buyer and make maximum profit on garments selling CPM cost need to be kept at a minimum level.
For Calculating of CPM you need to sum all direct labor cost and any other operational cost for a particular order or for a particular period.
5. CM/COM/MC
Cost of Making (CM/COM)/Manufacturing cost(MC) have to calculate after calculating factory CPM.
CM = (SMV × CPM)/ Expected Efficiency%
Suppose , any GMT item SMV is 4.7, Expected efficiency = 65.8 % , CPM[let] = $0.0267
To calculate the Cost of Making of a garment you have to collect the following information:
First of all, you need to get the monthly information of factory rental expense, commercial expense, utility expenses (Electricity, Steam, Compressed Air, Water), transportation cost, repair & maintenance expenses, salary, and wages expense, etc. suppose for all these expenses the total cost is 70000 USD.
Secondly, the number of functioning machine for a particular month. Suppose the number of machines is 120. Cost associate in the first section is for this 120 machine.
You also need the number of machinery to do the layout for the particular item for which we are calculating the cost of making. Suppose the number of machines is 30.
By using the existing layout, the amount of target production per hour (excluding the alteration and rejection of garments). Suppose 250 pcs per hour production will be there.
The total number of working days for a particular month. This can be 26 days (30 days a month, 4 days of holiday in a month)
Cost of Making (CM) Rule
= {(Monthly total expenditure of the
garments factory/ 26 days) / (Number of Functioning Machine of your factory for
a particular month) X (Number of machine to complete the layout)} /
[{(Production capacity per hour by using existing layout, excluding alteration
and rejected quantity) X 8 working hours a day}] X 12 piece
= [{($70,000 / 26) / (120) X
(30)} / {(250) X 8}] X 12
= [{2692.30 / (120) X (30)} / 2000]
X 12
= (673.08 /2000) X 12
= .33654 X 12
= $4.04/dozen
7. Conventional VS Modern Profit Theory
Conventional : COST + PROFIT = PRICE
Modern : PRICE – COST = PROFIT
Price should be moderate to get maximum order!
Cost should be minimized to get maximum profit!
9. Work Study
A systematic study of methods of work to improve effectiveness & set standards
2 stages:
1. Method study: study of current method & find out to implement the improved method
2. Work measurement: determine
the standard time required to complete improved method
Benefits of Work Study
Productivity improvement
Efficiency increase
Improved workflow
Improved work layout
Improved standards
10. Time and Motion Study
Time study: a work measuring technique to calculate basic time by finding cycle time & adding allowance
Motion study: a technique to analyze operators motion & set a standard by eliminating unnecessary motion
Two different theory but need parallel running to improve system known as ‘method engineering’
Time & motion study is a conjugal technique to process control, improve dissimilar work performance & set standard goals
IE is a combined package to improve by time study, work study & motion study
11. Line Balancing
Line balancing is a manufacturing engineering function in which the whole collection of production-line tasks are divided into equal portions.
Well balanced lines avoid labor idleness & improve productivity
Line balancing is for keeping workload (theoretical mp/actual mp) as 1 or less than 1 by balancing work as per capacity & target
Steps for Line Balancing
Bottleneck’ (constraint m/c or mp or operation that reduces productivity) have to find out
Find same m/c / m/c condition such as gauge/pressure feet/device/thread etc.
Find same m/c / m/c condition such as gauge/pressure feet/device/thread etc.
Find same m/c / m/c condition such as gauge/pressure feet/device/thread etc.
Find same m/c / m/c condition such as gauge/pressure feet/device/thread etc.
Find same m/c / m/c condition such as gauge/pressure feet/device/thread etc.
Find same m/c / m/c condition such as gauge/pressure feet/device/thread etc.
Costing of Knit Garments: During the consumption, it is good practice to use the measurement of middle size for calculation or the size which have most of the quantity. For example, If the style has 6 sizes then better to use size number 04 for consumption. Here we will show you the calculation consumption for the size “L”.
Costing of Knit Garments
Body length of the garments in cm. Say it is – 73 cm
Sleeve length of the garments in cm. Say it is – 19.5 cm
Approximate stitching allowance at body hem, shoulder joint, sleeve hem joint (in cm). Say it is – 10 cm
Chest width (1/2) in cm. Say it is – 52 cm
Approximate stitching allowance at each facet seam (in cm). Say it is – 4 cm
Approximate fabric wastage in various stage. Say it is – 10%
In this regard, fabric wastage depends on how many additional elements the garments have, which may change in any time. When there is rotary print in garments or enzyme stone wash than the amount of fabric wastage will be more than the normal level of wastage.
Knit Garments Costing Formula
What need to know or do before start costing
Fabrication: Take clear idea regarding the fabrication before taking the order from the buyer/buying house. After then, you need to ensure that you have a strong a good source of fabric.
Size specification: You also need to ensure that there is a correct size specification with the measurement of all the sizes, which will be ordered. Most of the time we see that PO sheet has come with a new bigger size which was not included during costing.
Fabric color: Try to know that, how many colors the style has &
also try to know that, color-wise order quantity
ratio.
Quantity: Take information regarding approximate order quantity.
Shipment date: Asked buyer for the shipment date and check with your production department, whether they have enough space for shipped out the followings qty within the require ship date or tell you’re a possible date. Test requirement: This will allow you to recognize the order need to any test or not. L/C payments term: Take a copy from the respective party previously and discuss with your commercial people regarding all the terms along with payment terms.
Inspection: Get a confirmation from the buyer that, who will inspect the goods. If there involve third party then who will pay the charge.
GSP: Please confirm with the buyer that they need the GSP or not.
Calculating Fabric Consumption
Body Consumption:
Calculate the body fabric consumption at first. If possible calculate it after making the pattern. Be confirmed regarding the dia. Calculate the consumption with adding + 5 gsm extra which fabric is sells in kg (s/j, pique, rib etc.). Or reduce 2” (in width) from the both side which are in yards (tricot, taffeta etc.). Moreover, if the garments are wash garments then make sure that, the pattern has the wash allowance.
Moreover, if clothes|the
clothes} square measure wash
garments then ensure that
the pattern has the wash allowance.
Rib: Calculate the rib consumption carefully because sometimes the garments have a rib at cuff opening & bottom hem. Some individuals erroneously do the consumption considering one cuff.
Neck tape: Calculate the consumption of neck tape.
Applique & others fabric: Ensure that, you’re not missing any appliqué cloth.
Estimate the wastage:Normally we add 9% wastage for the knit items. However, it’s may vary depends on how many processes the garments have. If it is with only front chest print then 9% is ok but if with all-over /rotary print, with heavy wash etc. then you must increase the wastage. Moreover, if the garments with pigments dye then add minimum 25 to 30% wastage because in this pigment dye garments reject percentage is very high.
Others Item
Print: If the garments have print then make sure that you have a clear artwork of it. Check the print quality, dimension & placement. Send the artwork to your printers for a better price idea. Many times, we found that the buyer has asked for so many type/kind prints in the same body which is so difficult for production. Such as, if the buyer asked for Flock + discharge & foil print in at the same artwork then it is not possible for production.
Embroidery: Discuss with your embroidery provider concerning the embroidery & take quotation of price.
Wash: Take the washing cost from the washing factory.
Test: Confirm the charges of the test
from the testing company.
Accessories and Trims
Sewing thread: Confirm that, which thread you need 100% cotton, spun polyester or filaments. Then you need to ensure the count 50/2 or 40/2 or any other denier. It’s may vary on fabrications. Regarding the pigment dye garments, we normally used cotton grey color cotton thread. Calculate the sewing thread consumption part by part & add require wastage percentage.
Labels: Take the quotation from your supplier for the entire woven
& satin/paper label.
Tape: Calculate the consumption of tape
if it has, such as Velvet, herringbone or canvas etc.
Elastic: Make sure which denier & width it need. Then take the quotation
from supplier.
Zipper: If the garments have zippers
then confirm that, from where you will purchase that. Many time the logo zipper
need to import the mold from abroad. Make sure the zipper quality, such metal
or nylon zipper. Check the zipper measurement from your production department
and get prices from your zipper supplier.
Button: Take the button price from your supplier if the garments
have it.
Inter lining: Calculate the
inter lignin price if the garments need.
Patch or badge: Calculate the patch or badge or others metal item
if the garments have.
Finishing item: Tissue paper, silica gel, hang tag, barcode
sticker, backboard, h/tag string, scotch
tape, security tag calculates the prices of these
items.
Hanger: Take the quotation of a hanger.
Poly: Make the measurement of poly. Confirm the quality & with
adhesive or not.
Carton: Find out the carton measurement & take the prices from
carton supplier along with top, bottom & divider.
PP belt: Take the price quotation of pp belt if the buyer asked it.
Commercial Cost
Normally we add 3% of total
purchase (Fabric cost+ other item cost + Accessories cost) as commercial cost
if the L/C payments terms are as sight.
If the L/C is 60 days deferred then you can add 7.5% additional cost of total
price and it will be 15% for 90 days deferred.
CM (Cost of making)
Calculate the CM after finalizing CPM of the factory. It varies depending on Product SMV &
Efficiency.
CPM (Cost Per Minutes) = (Direct
Labor Cost + Operational Cost) of the month/ Usage Minutes (Available Minutes)
of the month.
CM= (SMV × CPM)/ Expected
Efficiency%
Price Break Down of Polo Shirt
Description: 100% cotton pique
polo shirt with two buttons at front placket w/o any pocket. At first, we will
calculate the consumption of body fabric from Size spec which we have got from
the buyer.
Suppose,
i) The body fabric consumption is 5.10 kg / dozen
So, total yarn consumption will be = 5.10 + 9%
= 5.10 + 0.459
= 5.559 kg / dozen
ii) The current yarn price is $3.5.00/kg
iii) The current Pique knitting cost is $0.25/kg (Knitted by circular knit S/J M/c)
iv) Average color dyeing cost is $1.23 / kg
v) Normally Collar & cuff
consumption is 60 gram/body (1 pc collar & 2 pcs cuff)
So, for 12 pcs it will be -0.06 X
12 + 9% = 0.78 kg / dozen
vi) Collar & cuff Knitting
cost is $0.05 (knitted by flat knitting m/c)
Step: 1
Body fabric cost calculation:
Yarn price / kg = $3.50
Knitting cost /kg = $0.25
Dyeing cost / kg = $1.23
Finished fabric cost = $4.98
Step: 2
Collar & cuff cost
calculation:
Yarn cost/Doz = 0.78 X $3.50 = $2.73
Knitting cost/Doz = $0.05 X 12 =
$0.60
Dyeing cost = 0.78 X $1.23 = $.9594
Collar& Cuff cost / Doz = $4.2894
Step: 3
Total production cost:
Body fabric cost (5.559 kg X $4.98)
= $27.68 / Doz
Collar & Cuff cost = $4.2894 / Doz
CM = $5.50 / Doz
Accessories Cost = $2.50 / Doz
Total production cost: = $39.97 / doz
Final Step
Fob pricing of per piece polo
shirt:
