I attended the
EPC forum/trade show in Chicago two weeks ago. Given the
level of interest, this entire issue of SupplyChainDigest
is devoted to news and feedback coming from this event,
which the sponsors and Kevin Ashton from MIT labeled as
a “Moment in History.” Well, maybe.
First, some basics. I’ve heard some estimates of as
many as 2000 attendees. That looked high to me, but it was
certainly well attended. There were many supply chain executives,
and a high percentage of IT-related personnel – a possible
sign that companies are preparing to do something and are
sending forth the technical folks to figure out how to get
it to work.
I admit to being something of a cynic – as are others
that have been in the supply chain business for awhile – not
because we are anti-RFID, but because so many of the potential
benefits being touted are available TODAY from current technologies,
like bar code, the Internet and point of sale data, with
substantially less new investment.
But I think there are two really important observations.
First, it may not have been a “moment” in history,
but it did hit me at the show that we seemed to have crossed
a major threshold. Many of the world’s largest companies
have now at least mentally committed to the concept that
they will be able to track every product, everywhere, proactively,
in real-time. This is not something I think we really were
contemplating even a short while ago, and it has significant
supply chain (and other) implications.
The second observation can be summarized as “too many
people just won’t scan bar codes.” Yes, RFID
can do many things bar codes can’t, though it wasn’t
that long ago that bar codes were driving big savings everywhere
by eliminating manual key data entry and paperwork as goods
moved. But it appears in some operations, like retail back
office, even bar code is just too hard. We just can’t
scan stuff into receiving or onto the floor, despite the
Symbol wireless devices lying around everywhere.
I have summarized additional Symposium news and thoughts
below, in addition to the other weekly news and views section
nearby. Give
us your thoughts – are we at a “moment
in history”?

We received significant amount of feedback from
last week’s issue, especially around RFID and
privacy, as well on as the historically low state
of inventories.
Typical of the comments on RFID privacy issues: “What
people don't seem to get is that the existence of
this data is not the problem… But the important
control is the flow of this data.”
Another: “We have a long way to go before
we get to that type of intelligence in commercially
available products, or the technical infrastructure
required to support the transfer of information on
that order of magnitude is available.”
See more detailed comments below, including one
from someone who is currently using bar code to track
his own personal stuff!
Keep the dialog going! Give us your thoughts on
this week’s supply chain topics. feedback@scdigest.com.

The Uniform Code Council (UCC) and EAN International announced
formation of a new organization, EPCglobal Inc., which will be
charted with commercializing RFID technology based on the electronic
product code (EPC) standard. Under the new structure, the Auto
ID center will give up its standards work as of October 31, and
become the “Auto ID Labs,” working in conjunction with
EPCglobal on more basic research, rather than standards setting.
Current Auto ID center members retail some benefits, but must “re-up” to
really participate in the network and numbering assignment.
It makes sense to get the standards setting away
from MIT to an organization more suited to the effort.
MIT really just well filled a void in RFID standards
setting when other organizations couldn’t get
it done.
Importantly, there are plans for very aggressive
work to commercialize the technology, including an
Implementation Task Force comprised of member companies,
that is supposed to get its work done between now
and the end of the year.
But I think it will be interesting to see how EPCglobal
morphs. It certainly has ambitions for more than
standards works, with maintenance of Object Naming
Service (ONS) reference servers, in addition to touting
at the show its goal of being an “implementation
partner” for EPC technology, offering consulting
services, among other offerings.
While stating that it will fund itself through end
user subscriptions for EPC number registration and
vendor compliance/certification, EPCglobal at times
starts to sound a bit like a vendor itself, rather
than just a not-for-profit standards and educational
services provider (the traditional role of the UCC
and EAN). One has to wonder if there isn’t
some interest in eventually grabbing a transaction
fee for every ONS look-up, and/or a “for profit” potential
in this corporation’s future. I liken it to
the New York Stock Exchange, a private, non-profit
company that acts a lot like a for-profit organization.
What are your thoughts on EPCglobal? Let us know.

Looming over all the activity on RFID is the planned actions of
the world’s largest retailer. Vendors are announcing compliance
with at present non-existing standards. The questions of the day
are: what is Wal-Mart really going to do? And what happens to the
RFID momentum if it slows down its adoption plans?
The entire world it seems will be waiting for Wal-Mart’s
early November RFID meeting with its top suppliers.
More aggressive statements/mandates will set off
an even greater fury of vendor and user activity;
a more tepid approach could prick the balloon a bit.
Though Wal-Mart has backed off some of its earlier,
highly aggressive statements, evidence is that the
push will still be strong, albeit with some room
to slow down the effort based on reality. At the
Council of Logistics Management show in Chicago,
Gary Maxwell, Vice President of Logistics Administration
gave a good idea of what’s in store. Wal-Mart:
|
Is “committed” to
the technology |
|
Will not add “total cost” to the
supply chain |
|
Found a lot of glitches in its tests with Sam’s
Club – mediocre read rates, equipment maintainability
issues. |
|
Plans some DC tests in January
2004 with select vendors for receiving and shipping.
Data collection focus,
not linked to its production systems. |
|
More extensive roll-out in 2005, linked to
production systems. |
"Wal-Mart is
clearly betting that its activity will drive improvements
in core reading technology,
and substantially lower prices of both tags and readers.
Maxwell noted, just a few months away from the more
extensive tests, that “tag prices are too expensive
today.”
So Wal-Mart appears to be using its market leverage
to drive hoped for improvements in the technology
and price structure it needs to get the right ROI
out of RFID, rather than waiting for the technology
to mature and find a price equilibrium from the overall
market. It is being very aggressive in its vision,
but with enough wiggle room that it can delay or
pull back if technology and price developments don’t
occur quickly enough.
What will Wal-Mart really do? Does the industry
depend in the short term on Wal-Mart’s leadership?
Give us your thoughts.

At the show, EPCglobal announced Version 1.0 of the EPC Network,
meaning it has now provided a complete set of technical specifications
for every component in the Network - an "Internet of Things."
Those components are: the Electronic Product Code (EPC), the ID
System
(EPC Tags
and
Readers), Object Name Service (ONS), Physical Markup Language
(PML), and Savant.
EPC is the numbering system for the tags. Tags and
readers are self-explanatory. The Object Naming Service
tells the computer systems where to locate information
on the network about the object carrying an EPC,
such as when the item was produced.
Physical Markup Language (PML) is used as a common
language in the EPC Network to define data on physical
objects.
Savant is a software technology (or “middleware”)
that acts as the central nervous system of the EPC
Network, the glue that ties together readers, ONS
Servers and business applications (WMS, ERP, etc.).
As a version 1.0 spec, EPCglobal undoubtedly has
a long way to go before fully deployable. The bigger
questions about the EPC network to me reman. How
broad will the use be of web-based ONS reference
network, versus private tracking? And what is the
future of Savant, the MIT-developed (in conjunction
with Oat Systems) middleware? The software
is
currently downloadable for
free, though, based on the Savant
presentation at the Symposium, is still very early
in its development.
I spoke with a manager in the department of defense,
who indicated while the DoD is very interested in
RFID and EPC, they of course cannot have their data
flying over a public network. He questioned whether
others would share this concern. It does not appear
Wal-Mart is going to be relying on the public EPC
Network for its deployment.
So, while some light is starting to shine over
RFID tags and readers, the “EPC Network” as
an ubiquitous entity, still seems a little fuzzy.
What are your views?

Trade show floor was very busy for most vendors.
Tough to get into several booths.
One observer commented to me that vendors were moving
aggressively ahead, EPCglobal was trying to find
its place in this world, and most end user companies
were confused. Think this is a reasonably accurate
assessment.
Ester Dyson, internet guru and keynote speaker,
rightfully raised issues around who owns all this
data, and the many privacy concerns. One I hadn’t
thought of: your neighbor with a reader can know
everything you have in your house?
Those of us that have been at this for a while can’t
help but have a sense that we heard much of this
before. The reality is the expected benefits – lower
total pipeline inventories, significant reduction
in stock-outs, improved information flow among trading
partners – are the same as those we all heard
repeatedly in the early 1990’s for Quick Response
and ECR, and then again just a few years ago for
CPRF.
Maybe this time it will actually work.
But even given a little bit of cynicism based on
history, when Proctor & Gamble says it thinks
RFID can take out 50 percent of its total supply
chain inventories, you have to take notice. But I
think many of the lessons of these earlier initiatives – both
good and bad – are worth considering here.
More on that in a future issue.
I do believe that a substantial amount of the benefits
being touted for RFID are available today from bar
coding and related technologies, and was disappointed
that the sessions did not more explicitly address
the additional benefits from RFID.
Some did. Accenture’s presentation noted clearly
(if quickly) that if you already had a real-time
WMS with substantial bar coding, the benefits from
RFID in your DC were very incremental. When an attendee
from a CPG company asked another speaker about this
question, he mumbled something about line-of-sight
and moved on.
So, when evaluating the benefits for you, be sure
you separate the potential returns from current technologies
versus those from RFID, comparing total costs and
total benefits. There are unquestionably large FUTURE
benefits from RFID alone, like perpetual real-time
inventory monitoring, huge reductions in POS check-out
(and staffing) by whisking your cart through a portal,
etc. But those are many years off.
And I am convinced there is something that is just
sexy about putting a chip on something that excites
everyone from Time Magazine to CEOs, that a label
would just never do, and that is driving some of
the interest. But if in the end that gets us re-investing
in supply chain management, that’s a very good
thing.
Germany’s Metro Stores did an interesting
presentation on its use of RFID in both some DC operations
(pallet/case for picking, loading, store receiving)
and a few select SKUs for item-level tracking in
its Store of the Future. Metro listed some of its “lessons
learned” from its efforts that are worth noting:
|
Must focus on technical
reliability across the whole system – still
a lot of issues |
|
Set-up of each individual reading
system takes a lot of time |
|
This involves a lot of process
change – need to really focus on personnel
training |
|
Lack of standards today is a barrier |
It’s a long
way for those in the U.S., but Metro offers site
visits of its DC and Future Store
for those who are interested.
IBM made a presentation that included estimates
of total costs. These estimates (I believe at the
pallet/case level of tracking) were that 50% of total
costs would be for readers (one time cost), 45% for
tags (recurring costs) and 5% for integration.
Think the “integration” costs, which
include everything outside of tags and readers, seems
very low to me versus historical norms for other
technology initiatives, and there is no clear reason
why RFID should be different. Nonetheless, this is
a simple but effective framework to think about costs
and calculate your own estimates.
Predictions in several places were for a 5-cent
tag by 2006. However, this was based on unspecified
assumptions about tag volumes and standards adoption,
which will commoditize products and drive down costs.
But I do think we could see 5 cent tags in 2-3 years
if all goes right.
My best intelligence tells me current tag quotes
are in the 20-25 cent range.
And frankly, for a can of Coke, doesn’t the
tag basically have to be free, like a printed UPC
code, for this to really work economically? The bottlers
will change can suppliers today for a fraction of
a cent per can reduction.
That was the mantra from all of the consultants
and most of the other speakers at the Symposium.
It can be summarized as “don’t wait, just jump
in and do something, you can figure it out later.”
OK, that’s a bit of an exaggeration, but not
far off. Think a more prudent view is on order. I
do not believe one has to panic about being “left
behind” and racing to do a pilot. On the other
hand, one would be crazy not to be devoting some
resources to understand the landscape, monitor the
technology environment, dialog with trading partners,
and do some business case analysis. If a pilot makes
sense after this at reasonable costs, go for it by
all means.
But remember that there are many consultants out
there seeing a Y2K type bonanza from RFID adoption.
Did You Go to the EPC Symposium? Yes or no, give
us your thoughts.

“Sure, the ideas are currently being developed in our R&D labs, but
we are still working on operational, practical, prototypes for the simplest of
applications - security and inventory tracking! When the tags are only a fraction
of the packaging, or product cost, and the technology to read them and transmit
the information, is readily available, then we can begin to worry about Big Brother.
I personally think there is an argument to be made for being able to "track
people" using this technology and I am not opposed to developing applications
to do just that. I, as a parent of two young children, am concerned about their
safety and well being in today's world.”

“I would love to have my refrigerator know
what is in it, and what is needed. I already track
things in my house with their bar codes. But the
important control is the flow of this data. Personal
privacy and the freedom to chose demands that I have
the right to decide where this data goes. If I am
online 24/7 then I could let it go to Coke, or the
grocery store. Or I should be able to chose that
it stays right on the touch screen in the fridge
and will print a list for me when I am ready to go
to the store or that I can deactivate the tag when
it comes into my house or leaves in the garbage.
Don't be scared by the data, be certain you control
the information. BTW if someone sits outside my house
and tries to scan it, very simply it's called "trespassing".

“I believe the shortness in existing inventories
is a reflection on the horrible state of the economy
and low consumer demand. As a consultant in distribution,
materials handling and logistics, we have not been
seeing the problems in stockouts which one might
expect given the low inventories. Businesses are
learning - and wanting - to live with the lower inventories
and are utilizing WMS, materials management and other
processes in order to make that happen. I have serious
doubts that the economy is going to experience any
noticeable growth anytime soon and therefore doubt
that the low inventories will help drive the "robust" growth
to which you refer to in your article.”
Peter Sobol
Principal, Operations Dimension
Tompkins Associates
Commented one logistics professional from an industrial company,
who asked to remain anonymous:
“ We have driven inventories down to the bone and it has cost us some customer
service problems, but it was worth it to maintain profitability. When things
recover we will address those problems, but do think we have learned some lessons
through this about how to drive inventory down.”
