Problem/Issue Statement
Xan Salgado Badas (head of IT for Inditex) and Bruno Sanchez
Ocampo (technical lead for the point-of-sale system) are both concerned that
the current POS infrastructure for its largest chain of stores Zara may be
outdated and a risk for the company.
Although Salgado is arguing for retooling the current operations and
Sanchez is opposing the notion, both men have taken each side of the contention
at various times. While the
current system appears to be working, it is running on DOS, an operating system
that is no longer supported by Microsoft.
Additionally, although DOS is currently is compatible with the terminal
hardware may not be in the future and the hardware endor is not willing to
contractually commit to insuring future compatibility with DOS.
The main problem is that the current IT
structure, a custom software application written on top of DOS, is both
outmoded and limited in its capabilities, and represents a significant risk to
the company should its terminal hardware no longer be able to support the
archaic operating system.
Some of the symptoms of this problem are
the inefficiency created by running an older system, such as the inability of
employees to look up their own inventory or other store’s inventories in real
time or spending excessive time to complete returns on the small screens on
their Personal Digital Assistants (PDAs).
The scope of this problem is the entire
chain of operations related to Inditex’s Zara fashion stores, from the vendors
to the warehouses and distribution
centers to the actual store properties.
The POS system impacts the way each part of the chain interacts with one
another and an upgrade would significantly alter those relationships.
Situation Assessment
The Zara fashion stores rely on the
speed of their product, needing the latest fashion products to satisfy the
needs of their customers. Ideally,
an IT system in place would be able to track all changes in inventory
throughout the 500+ stores and manage this updated database in real time. The company maintains a website, but
does not allow for the sale of clothes through this site, primarily since the
return rates for online sales of clothing are much greater than those in the
physical retail locations. The
company is averaging an opening of one store per day and is considering further
expansion globally and especially into European markets like Italy where only 3
Zara locations exist but there is potential for a much greater presence. When a new store is opened, all the
manager needs to do is insert two installation floppy drives into each terminal
that contain DOS and the required applications. If
anything were to malfunction with the POS terminal, a reinstallation was very
straightforward and consequently no IT support was required to open a new store
or was there any need for a large IT support assistance organization. In the event of a serious problem with
a POS terminal, a complete software reinstallation was similarly
straightforward. As a result, no IT support was required to open a new store,
nor was it necessary to run a large IT support organization to assist the
stores. The POS system in place is
expected to support further expansion if hardware vendors maintain its
compatibility with MS DOS.
The decision criteria for a new POS
system are would it maintain the operational status quo and not cause any
disruptions in current operations, how easily it can be installed and managed
by each store, how much time it can save by adding greater functionality, would
it protect the company against the risk of maintaining obsolete and resulting
incompatible technology, and would it fit in with the current business model of
Zara’s such as the great autonomy given to managers and the consistent
expansion into global markets.
List of Plausible Alternatives and Evaluation of Alternatives
The first option is to maintain the
status quo and maintain the current system in place. Within this option would also be the choice as to whether or
not to purchase additional units of the existing POS terminals to offset the
risk of the vendor no longer supporting DOS. This choice would be an antiquated one, and seek to
keep tasks such as updating inventory a manual one. This would require no immediate investments in training
employees on a new system, programming POS terminals or applications on those
terminals, and there would be no time where operations must be limited or
delayed to accommodate these upgrades.
This would put the company at risk of lagging technology, even if they
were to purchase a large amount of terminals that could ultimately become
incompatible with necessary peripheral devices. This option would keep the
stores isolated from one another with the exception being the one modem in each
locale. No new functionality
exists with this alternative.
The second alternative is to upgrade and
add functionality to the POS terminals by integrating a new operating system,
primarily Windows, Unix, or Linux. Inditex could update the POS applications to
incorporate the functionality and allow the store personnel to use a large
screen, keyboard, and mouse to quickly execute return transactions. The company could build wireless
networks within and between stores so that installation through floppy disk
would no longer be necessary and with each location connected to the Internet,
each store could know the theoretical inventory of its SKUs (stock keeping unit
or the combination of garment, fabric, color, and size). This would require a sizable investment. To port the
existing OS in DOS to a new OS would require 15,000 hours of programming time
at a rate of 450 Euros per day, or 5,000 Euros to expand the current POS
application. Each store would need
to allocate 32 hours to the installation of the new OS system, establishment of
a wireless network, and training of staff on the new system at a rate of 2,000
Euros per day. This would, though,
mitigate the risk of obsolete technology, add greater functionality to store
operations through completely updated information such as inventory head count,
and even allow for the possibility of online clothing sales which could
generate significant revenue and now be possible to handle since returns would
be significantly less difficult through new allowable processes free of
previously requisite PDA devices.
Recommendation
I would recommend that, although the
investment figures induce sticker shock at first, the company migrate to a new
OS system and establish wireless networks within and between stores. The instinct to uphold the status quo
and resist technological change is one that will limit Zara’s growth potential
both in its existing stores and its future expansion. Ultimately, a POS system running on DOS is limited in how
much functionality it can provide to retail stores and the distribution
network. Being able to access real
time information and having all stores be connected to each other and the corporate
employees is invaluable.
Eventually some portion of the POS system will become completely
outmoded and a DOS operation will not be able to fully interact with some
peripheral or necessary application.
To stave off the staggering loss that will accompany the inevitable
phasing out of DOS compatibility, Inditex must endure the up front investment
cots of modernization and update its current systems.
Presentation
The consulting group must keep in mind
the context of Inditex’s situation, understanding that the company is generally
located in Europe with a slight presence in global markets and is seeking significant
expansion. The presentation should
anticipate future changes in the market and do the difficult task of accounting
for the accountable by assuming how unexpected further technological changes
and the current POS system or an updated one could handle market adjustments. The presentation would benefit
greatly from a solution that might not just be a full upgrade, but rather a
sampling of the updating opportunities such as further developing the custom OS
application and establishing wireless networks. Lastly, the presentation should
give a fair representation of the benefits and drawbacks of either keeping the
current methodology or updating to a new OS and wireless networks.
Reflection
Mr. Sánchez and Mr. Salgado,
I have concluded that despite the insistence by the
consultants in last night’s presentation that the responsible choice would be
to port our POS application for our terminals to a Linux operating system, that
at this time a full-scale upgrade from DOS would be too costly and risky considering
our business model and current healthy IT system. Over the past seven years we have been able
to grow our operating revenues by nearly 3 billion Euros and multiplied our net
income by a factor just over 6 under the support of our current legacy
DOS-based terminals. I am forced to
disagree with the consultants’ notion that porting to a Linux OS and installing
wireless networks would provide a degree of functionality that would dramatically
improve our company’s bottom line. Zara’s
business model relies on responding to fashion trends and quickly overturning each
retail location’s inventory, and the value of maintaining an immediately
accessible and completely exact inventory figure is definitely a benefit but
not a necessity.
I must admit that my preparation thoughts were more aligned
with what was presented to us then what I am now recommending. I originally did propose that in order to
stave off the significant losses associated with the terminal vendor phasing
out DOS compatible terminals, we should make the sizable investment to migrate
imminently to a new OS. This was an
argument that the consultants made, warning us that our current expansion rate
of a store a day could be completely halted if our terminal vendor decided to
no longer supply us with terminals that were DOS compatible. At the time of my writing this I was largely
concerned that our terminal vendor would not contractually obligate to continue
distributing DOS-compatible systems.
However, upon further consideration, I now realize that what you suggested, Mr. Sánchez, would be a much more reasonable approach. We could purchase a supply of the current terminals and if our supply vendor were to no longer offer devices that supported DOS, which they have actually assured us would not occur, we would then “have plenty of breathing room to port the application a new OS.” The consulting team did make sense, though, in noting that we are the only customer of our vendor that operates in a DOS environment that it does seem like an inevitability that DOS will become outmoded. To address this, I propose that we begin the work necessary to rewrite our application terminal software so that it can be used on a new operating system. This would require an approximate programming time of 15,000 hours, and if the estimate given by the consultants of a 1 year time frame for implementation of their solution is accurate and relevant, then we should begin this initiative as soon as possible. Once the programming is completed, we can then begin on a trial basis switching a sample of our retail outlets to a new OS, possibly the Wincor Nixdorf TPLinux the team proposed
.

Although the consultants’ presentation was very thorough and
extremely detailed as to the specifics of the proposal (with the exception of
the ambiguity of the exact fees associated with installation and support of a Wincor
Nixdorf solution), I must come down on the side of conservatism. Our current business model can be seen in our
operating expense figures in comparison to one o f our largest
competitors. In 2001, Gap was able to
achieve operating profits of 379 million Euros from a gross margin of just
under 4.7 billion Euros and Inditex was able to generate over 300 million Euros
more in operating profits from a gross margin under 1.7 billion Euros. To an outside observer, our IT infrastructure
may seem antiquated, however it is one of the many reasons that we have been
able to keep our operating expenses to a minimum and enjoy such healthy growth
in profits. By preparing ourselves for
the future by beginning to program our terminal application for a new OS, we
can cautiously modernize without creating any great disruption to our 1,558
locations worldwide.
