Lean is way
to reduce or if possible, then to eliminate the waste. It can be applied in all
sector, like from production to marketing to retail. As we know that there are
basically 7 waste or muda.
2) Inventory
3) Motion
4) Waiting
5) Over-Production
6) Over-Processing
7) Defects
In short we
can call them as “TIMWOOD”.
There are
many techniques to find the waste. But before that we must know the product
structure of the Industry. The case
study by Ulla Lehtinen and Margit Torkko was on the Food Manufacturing Company. Here is the
comparison of the Food and Fashion Retail Industry at superficial level.
FOOD SUPPLY
CHAIN INDUSTRY
|
FASHION
RETAIL INDUSTRY
|
·
The products is
perishable items.
|
·
The products is
non-perishable.
|
·
Very less
variation in design.
|
·
One of the most
versatile industry in terms of design.
|
·
The plant
Layout is mostly “Fixed position Layout” and process type layout.
|
·
Mostly follows
the “product type layout”.
|
·
Less
Innovative.
|
·
Very Innovative
in terms of styles, designs.
|
·
Only has to
forecast the demand by viewing previous sales data.
|
·
Forecast of
consumer taste and demand and also keeping in mind about the trend change
scenario or new penchant for the future product.
|
·
Manufacturing
and Packaging is fast process.
|
·
Manufacturing
and packaging is tedious job.
|
So, retail
store has limited storing space. The Fashion forecaster can refer the previous
data about past sales record to take some inspiration. But it is of not much
help. The Fashion Industry is very capricious in nature. Forecasting is not an
easy job. One has to really comprehend the mindset of the mobs and also their
fickle-mindedness. We have to look into every matter not only from A-Z but
beyond that too. It is a risky business and one really has to prepare for every
contingencies.
We often
listen the triumphant journey of Zara. The multi-billion industry rest in niche
of Spain and becoming same old cliché for success story. The answer is very
simple because the ZARA control all the steps of manufacturing, distribution
and sales in order to cut costs and to make huge gains in speed and flexibility
is the key to a retailer’s survival. The labor charge is high in Spain but
still ZARA running the manufacturing unit over there. The Zara manufactures
modicum amount product with many style variations at a time. By cutting the
advertising cost and inventory costs and adjusting to fashion trend quickly.
Methodology
of Value Stream Mapping:
- First and Foremost determine the demand.
- Calculate the available time from order of products to retail.
- Calculating the Takt Time, colloquially know as pitch time in Manufacturing Industry. Takt is derived from the Deutsch language means ‘meter’.
-
Comparing the total cycle time against the Takt Time using any form of chart or graphs like Bargraphs and Histogram as used in the Food Supply chain case study.
-
Draw a VSM and there you can provide the Takt Time at each step.STAGES UNDER SCRUTINY:
- 1) PRODUCT STRUCTURE (Garments)
Packaging
|
Brand
|
Size
|
Style
|
- 2) Identifying the distribution channel:
Merchandiser
|
Merchandiser Warehouse
|
Retailer Warehouse
|
Retail Store
|
- 3) Map Physical Location:
At this
stage we should be ready to put physical location in value stream. After that,
we should add material flow into the map. Production cycle time can be added to
the map here.
- 4) Identify the Information Flow:
This helps
in knowing the authenticity and accuracy of the data. This bring transparency
in the information flow. This helps in realizing the hidden problems in the
whole system. Nowadays, Electronic Interchangeable Data is more commonly used
in order to track the status quo of the whole process. Thus it provides real
data time, and so it helps in quickly responding to the matter.
- 5) Develop Alternatives:
At this
point we should identify the one of the 7 wastes. The collective brainstorming
is done by the team members after viewing the whole mapping and the data in all
forms. The pictorial data give clearer image about the whole process.
CONCLUSION:
In Fashion
Retail Industry the biggest challenge is completion of order in time. This can
only be possible if the non-added value ingredients are permanently removed.
The Fabric constitutes 75-80% of the whole garment cost. So, from the very
beginning the CAD department should plan in such a way that it shall be able
optimize the marker planning. This reduces the Fabric waste. The cutting
department should be proficient in laying and cutting. If this stage is cleared
then the opulence amount of money can be saved.
Another
grave endeavor is Supply chain. The success is only possible if all the teams
collectively coordinate and take action accordingly. The Inventory is common
problem in retail. So generally speaking, the off season product are disposed
at lower price, sometime reaching till 90% off. The new style product is never
compromised with the old one in this industry. Albeit there is no such expiry
or perishability of the product, it is just the abstraction ism in the mind
which make them obscure for the sake of new trend.
Excessive
transportation is another big concern as it creates chaos and waste time,
gasoline and money. The proper conduit of information can bring stability. The
Material Handling should be minimized in order to maintain the certain
standard. Once the garment reaches to the retail store then material handling
is not a so much concern. But still as a customer it is our candid duty to use
the garment in trial room with delicate manner without exempting the essence of
the Garment. “If Garment is our prerogative then its delicate trial is our
duty.”
OTHERS
TOOL:
There are some other method like Process activity mapping,
Quality Filter Mapping etc. As far as Fashion Retail Industry is concerned
Value stream mapping, Process activity mapping, Supply chain Response Matrix,
Value-Analysis Time Profile can be used.
The Quality
Filter mapping is unnecessary as the quality check is done at very stage in
manufacturing unit itself.
The Demand
Amplification Mapping can become obsolete because nowadays the lead time itself
is around 45-60 days (Zara with only 15 days only!)
