RFID-based technology generally,
and the Electronic Product Code (EPC) subset of that technology
more specifically, has generated an virtual tsunami of interest
by companies across the globe as a potential mechanism to improve
supply chain processes. It has also led to a substantial amount
of hype, as hundreds of consultants and technology vendors
clamor for a piece of the looming gold rush.
This hype, combined with the aggressive plans and to a lesser
extent roll-out of EPC technology by Wal-Mart (based on supplier
mandates for EPC tagging), has also led to much confusion
and concern in the market, as the current reality of RFID
across many fronts is well behind the rhetoric. This is exemplified
by the “just go out and do it” call from many
consultants and industry pundits, as if beyond some prudent
experimentation with a promising technology a company should
pursue RFID systems simply because they are there.
RFID, in many if not most supply chain applications, is fundamentally
better than bar codes, the predominant “auto ID technology” in
use today. By reducing (not eliminating) line-of-site scanning
requirements, and the need for manual scans, RFID ultimately
can drive efficiencies into many supply chain processes.
But this is dependent on the performance and total system
cost of RFID-based systems providing enough incremental advantage
over alternatives that this investment is financially sound.
We aren’t there yet, at least in the EPC/consumer goods-to-retail
supply chain. RFID is well-justified and delivering value
in many other application areas today (manufacturing, asset
tracking, etc.), and has in fact been doing so for many years.
Wal-Mart efforts, in fact, can be fairly seen as an effort
to use its size and power and the collective investment of
itself and especially its suppliers to drive the performance
and cost down the maturity curve far faster than normal market
forces would have achieved.
This is usually discussed in the context of when a company
can reach a level of volume at which it becomes economically
feasible for a company to move EPC tagging from being a function
of distribution processes (very expensive) to manufacturing.
But the reality is that for RFID to bring real value and
reach critical mass, there are a variety of interesting “tipping
points” that must be crossed at both the industry and
individual company level. These include:
 |
Volume Tipping Point: As mentioned above,
when is there enough volume for an individual SKU or complete
product line to justify more economical EPC tagging further
upstream in the supply chain (manufacturing, suppliers)? |
 |
Cost Tipping Point: When will fixed and incremental EPC
costs reach a point
where a true ROI is possible? |
 |
Performance Tipping Point: When will read rates reach
a level of consistent virtually 100% performance that systems
and process can be designed with confidence and automation,
rather than as part science projects with lots of exception
processing
required and incomplete data flows? |
 |
ROI Understanding Tipping Point: When will the real ability
of RFID to generate substantial ROI be understood at the
level of understanding that we have traditionally required
of technology? |
 |
Ecosystem Tipping Point: When will there be enough support
throughout the supply chain, including the incredibly challenging
effort of having suppliers do source-level tagging, to
enable RFID to be used throughout the chain, and tagged
and read
where it optimizes cost and benefits? |
 |
Software Tipping Point: When will there be scalable software
that can take advantage of RFID data, and when will those
be deployed and start delivering
value? |
Below are listed 10 key developments that must occur for EPC-based
RFID systems to pass these multiple tipping points and deliver
real ROI to users on all sides of the value chain.
Far too often, the potential benefits of RFID-based systems
are described in ways that make it appear as if the key to
realizing the benefit is use of RFID, when in fact these same
systems and benefits could be achieved using traditional bar
codes. For example, use of RFID to support location of inventory
in a warehouse, while most distribution centers using bar code-based
WMS already have extremely high levels of inventory-location
accuracy today. Similarly, the potential benefits of applications
such as supply chain visibility and product recall are not
being missed because RFID has not been available, but rather
because companies generally have not chosen to invest in them
as yet.
The confusion over the incremental benefits of RFID versus
other auto ID technologies and deployment of new applications
generally needs to be eliminated to understand the true cost/benefit
equation.
As Gartner analyst Jeff Woods has written: “You should
always compare the incremental benefits of RFID tagging to
the incremental costs of RFID tagging. That is, RFID must be
intrinsic to the benefits of the project or it isn't a sensible
business decision to use RFID. Absent the intrinsic benefits
that flow directly from RFID in a project, you should not invest
in it, because you'll still get the same benefits with reduced
cost.”
While RFID can deliver incremental benefits, and companies
forced to apply tags should obviously look how to best recoup
at least some savings from this investment, incremental analysis
is key. This needs to be more than a comparison between having
RFID and having no system at all.
It doesn’t matter who pays the initial “freight” – the
retailer or (as is occurring in retail-driven initiatives)
the manufacturer – EPC-based programs must clearly demonstrate
how their deployment will lower total supply chain costs.
Regardless of how the initial cost is absorbed – nominally
by the suppliers, as in the case of Wal-Mart, or as an add-on
to product cost, as with the U.S. Department of Defense, at
minimum the variable cost associated with tagging will be included
in the cost basis manufacturers use to determine their pricing.
For EPC to work, these extra costs must be clearly surpassed
by the total savings to the specific supply chain – and
manufacturers and retailers must share in that savings.
The business case for this total supply chain savings (and
sharing) has yet to be clearly established.
The Auto ID Center at MIT performed a great service to the
RFID and broader supply chain industry in creating a vision
for a low cost tag that forced technology providers and end
users to focus on tag and system designs that dramatically
lowered the inherent cost structure of existing RFID tags.
One unfortunate result of that good work, however, was the
notion of the “five-cent tag” that might be possible
from such a design, which has subsequently been adopted by
wide segments of the industry as the magical level at which
RFID suddenly becomes financially practical.
The reality is that tags at the item level for basic goods
will have to be well below five cents – approach “free”,
as are current UPC codes printed as part of the packaging – before
they make sense. This is also likely true even at the case
level, where current distribution costs per case will not
support a five-cent tag.
The discussion needs to be around determining at what level
of tag pricing do EPC applications deliver ROI and total
supply chain savings. This target will vary by the unit of
measure, value of the goods, and use of RFID in business
processes. “Waiting for the five-cent tag” (and
we can only await the mega-announcements for the first tag
manufacturers to get there) is of little value, and muddles
the dialog.
While talk about the five-cent tag isn’t productive,
it is clear that the current costs of tags, the even-higher
costs of tags embedded in labels, and high extra costs of (often
manual) application are well above the level that can deliver
total supply chain savings.
There is strong debate about the level to which tag prices
themselves can ultimately fall, including opinions from some
analysts who believe they are unlikely to get below about ten
cents for several years. However, several manufacturers dispute
that opinion, and other developments, such as “printable” antennas
and new manufacturing techniques, hold the promise of much
lower tag prices.
The variable cost of tags and application must come down substantially
even at the case label for ROI to be achieved.
While the EPC Gen 2 standards offer a solid, global standards
platform, recent intellectual property battles, and some continued
confusion amongst what groups will sanction what standards
(e.g. EPC Global, ISO). Additionally, lagging standard at the
reader/data acquisition level hinders acceptance by the IT/Network
community. These factors simply mean that the push for widespread
deployment remains ahead of the standards processes critical
for achieving system lower costs, reducing user risk, stabilizing
technology platforms. There is too much still in flux.
Currently, EPC deployment is a quasi-science project, with
substantial investigation and issues around read rates, tag
placement, SKU-tag type-physical placement decisions, and other
issues.
While some in the industry have touted the benefits that can
be achieved from even partial read rates, the reality is
that currently read rates are often poor even through portals,
and basic necessities like robust fork truck readers do not
yet exist.
EPC will ultimately achieve quicker adoption if expensive
tagging requirements are not forced upon manufacturers at their
expense far ahead of ROI, but rather at a measured pace that
seeks to achieve true win-win scenarios. As the Grocery Manufacturres
Association noted in its recent report A Balanced Perspective:
EPC/RFID in the CPG Industry, “Trading partners should
seek to create a reality-based plan that yields a positive
ROI and seeks economies of scale in a limited geography before
a broader rollout.“
There are some in the industry who believe that the ROI from
RFID is clear, at least at a given level of tag costs. Others
are more skeptical. The “business cases” developed
by many consultants often lack enough granularity to be meaningful
for real decision-making and investment.
With the increasingly realization today that results are primarily
a function of execution, and less so the result of “insight,” EPC
thought leaders (especially on the manufacturing side) should
more widely and openly detail how they expect to get real ROI – and
let this analysis be subject to the scrutiny and review of
other supply chain professionals.
The reality is that software application support for RFID-based
processes is very immature - really just evolving. Most of
the work at this point has been to simply enable tag encoding
and reading (RFID middleware) and support for basic EPC compliance
processes.
RFID is just a data collection technology – it cannot
deliver widespread value until a broad range of applications
emerge (some new, some re-tooled version of existing applications)
in software categories such as WMS, ERP, analytics (there are
some early offerings here), visibility, demand planning, replenishment,
etc.) While many vendors are building solutions, it will be
some time before they are really available and then implemented
by EPC users.
Everyone agrees that costs of distribution-center-based “slap
and ship” process are not scalable, and involve far too
high of costs to deliver total supply chain savings.
However, the focus on getting to the “tipping point” of
manufacturing-level tagging generally seems to assume that
the “manufacturer” is doing the production itself
domestically, as is typical with most large consumer packaged
goods manufacturers such as Procter & Gamble and Clorox.
The tremendous growth in offshore manufacturing in other sectors,
however, means that for many retail suppliers, the only economical
point of tagging will be for outsourced manufacturers to
apply and encode tags. Considering how difficult it is for
many of these same companies to work through even basic labeling
issues with their suppliers (international and domestic),
it is clear that the processes and integration involves for
this to scale will be a slow and difficult process.
RFID offers enormous potential for supply chain process improvements
and top and bottom line financial improvements. Despite the
hype, substantial barriers exist to crossing a variety of “tipping
points,” and the more users and vendors focus on addressing
these realities, the faster the promise of EPC will be realized.
