Dana Gardner: Hello, and welcome to the next edition of the HP Discover Performance
Podcast Series. I'm Dana Gardner, Principal Analyst at Interarbor Solutions,
your moderator for this ongoing discussion of IT innovation and how it’s
making an impact on people’s lives.
Once again, we're focusing on how IT leaders are improving their services'
performance to deliver better experiences and payoffs for businesses and end
users alike, and this time we're coming to you directly from the HP Discover
2013 Conference in Las Vegas. [Disclosure: HP is a sponsor of BriefingsDirect podcasts.]
Our next innovation case study interview highlights how retailer Guess Inc. has used HP Vertica
to both speed up and better distribute its big-data analytics capabilities.
We'll see how Guess can increasingly predict how to satisfy its shopping customers and we'll
specifically look at how Guess's IT organization came to grips with adopting and implementing a
big-data platform to bring more of a democratization of data and better access to its employees.
To learn more about how Guess has slashed the latency between data gathering and actionable
insights, please join me now in welcoming our guest, Bruce Yen, Director of Business
Intelligence at Guess Incorporated. Welcome.
Bruce Yen: Dana, thanks for having me here. It's a pleasure to be here and be able to share what
we’ve done with HP Vertica.
Gardner: Great. Tell me a little bit about why just plain, old relational databases and legacy IT
weren’t doing the job for you.
Yen: About three years ago we began searching for a new database platform. We were hitting a
lot of performance bottlenecks on our data loads and performance. We also saw the competitive
landscape out there with lot of our competitors embracing alternative solutions to their traditional
database platforms.
Gardner: What was it about Vertica, and maybe more importantly, what sort of requirements
were you for in order to get to where you wanted to be?

2. Yen: The first thing was performance. We needed to improve the query performance. A lot of our
users were asking us to do a lot of queries with very low-level detail inventory, and it was very
costly from a performance standpoint to be able to serve those queries up. There were some
queries that wouldn't even come back.
Secondly, from a performance standpoint, we wanted to make sure that a lot of our East Coast
stores would be able to receive the reports early in the morning, and we were having problems
just serving those up on a daily basis on time.
New solution
The last part was with any kind of innovative analytics, any kind of cutting-edge analytics. We
knew that that platform really wasn't going to help us do any of that. So we needed to find a new
solution.
Gardner: Before we go any further into what that solution did for you, let's learn more about
Guess Inc. We know one of your popular and well-known products is your jeans, Guess Jeans,
but there is more to it than that. Tell us a bit about the organization.
Yen: Guess has been around for more than 30 years now and we've grown from primarily a U.S.
retailer into more of an international retailer.
If you look at the '80s, lot of people from the States remember us for the triangle
on the jeans. We were primarily a wholesaler in the beginning. Now, we have
over 1,600 stores worldwide, and about half of those are run by licensees. We sell
a wide variety of lifestyle products, targeting primarily younger women in their
late teens to early 30s.
Gardner: So it's critical to understand that market, and this is a dynamic market. People's tastes
change and tastes are also, of course, different from area to area around the world. What have
you gotten as a result of Vertica? Can you give me some of the key performance indicators that
now demonstrate what you can do when you've got the right platform and the right data.
Yen: I like to look at it this way. First of all, it's foundational, the foundations for just baseline
performance. Have we met those goals? With Vertica we have. We've been able to meet all of our
service-level agreements (SLAs) and serve up the reports on time. Not only that, but now we're
able to serve up the queries that we weren't able to do at all.
When you move aside from the foundational, the next steps are analytics, being able to apply
analytics and go through our data to figure out how we can apply best practices to see how we
can gain a competitive advantage. We've been able to take our transactional data and look at
ways of taking the stored data and applying that into our e-commerce site to get better product
recommendations for our e-com customers. That’s something that we couldn't have done with
our existing system.

3. We have our customer relationship management (CRM) system. We have our loyalty
segmentation for which we use Vertica to do all of the analytics and we feed that data back into
our CRM system. With the data volume that we have, we could not have done that with our old
system.
So it's opened up new doors, but not only from a foundational standpoint. We've been able to
meet our daily needs, but we've been able to set ourselves up to be competitive in this area.
Gardner: And has being able to gain the speed and handle the complexity prompted you to then
seek out additional data to put into your analytics, so in a sense of not feeling limited as to where
you can go and what information you could bring to bear?
Different data
Yen: Definitely. We've been looking at different things lately. We've been looking at different
types of data -- loyalty data and customer data -- that we get from our customers.
In being able to give our users a holistic 360-degree view of what's happening
from that customer standpoint, Vertica has been very critical in keep pace and
enabling us to do that.
Gardner: Of course, it's important to get more data, manage it, and perform what
you need to do with it. It's also important to deliver it in a way that people can use and to get to
what we mentioned earlier about that democratization. Tell me how you've been able to deliver
this out to more people and in an interface and device fashion that they really want.
Yen: That’s a great point. Everyone talks about big data these days, but big data, if you can't
serve it up to people, if they can't use it, and if there's not a pervasive use of the data, is really
useless.
We're pretty innovative in what we do from a mobile standpoint. For the last two years we've had
an iPad app that's powered by the Vertica back end. We have this iPad app that over a 100
merchants in North America and Europe use.
It's been able to take a lot of the data, a lot of the stores’ data, a lot of the selling information. It's
allowed them to travel to the stores, be in meetings, or at home on the weekends, and they can
look at the best-seller information. They can look at the sales and do it in a way that is actually
fun.
It's not just a bunch of dashboards or reports that you open up and look at, but we've made it very
interactive and we’ve created workflows in there. So that really draws the user into wanting to
use that information and wanting to ask different questions.

4. Gardner: And for this combination of the power of the platform, the quality of the data, and this
distribution capability, can you give us some metrics of business success? Where this has helped
you. Do you have any concrete things you can point at and say it's really working and here is
how?
Yen: We’ve looked at that in different ways. One of the initial points that we're analyzing in
terms of return on investment (ROI), the easiest one is the amount of paper that’s being saved.
You can count up the reams, how much they cost, and multiply that, and there is some significant
saving there.
But that doesn’t really excite anyone. It's great that we've been able to save paper, but the
argument is, well, you also had to buy new equipment. These iPads aren’t free and the mobile
device management software and everything else that's associated to it is a new ecosystem. So
there is a lot of new cost there.
The exciting thing is being able to see our users look at the data and make the decisions. Before,
they would have to stop at a meeting and go back to their desks. That decision that takes an
instant now used to drag on for two or three days, maybe even a week, and I've seen that in
action.
It's done a good job
Ican't give you an actual dollar figure, but I've seen them make decisions to change the
allocation of certain items as they are looking at that information. As I was training some of our
executives or power users, I would see them pick up the phone and actually make decisions to
impact the business. So I know that it definitely has done a good job there.
The exciting thing is it's kind of democratized this information and this data and demystified it to
a point where everyone can access it and everyone wants to access it. I’ve never seen users get so
excited about a platform or an app. We've got emails saying, "Can I please have this app. I saw
one of my coworkers using it. Could I please?" Before, we were never asked that way.
It was always, "Can I get a copy of that report. No big deal if I get it now or later." But here,
people really, really want to use it, and we could tell that we hit something.
Gardner: It's always good when you're in IT and you're perceived as a hero and not something
else. Let's talk about the IT experience. Earlier on, you had to go on relational databases and
traditional legacy approaches to data. You went to a new platform. What was it like to install?
Did this create some skills gap? How was this received, and how did you react in terms of your
IT people?
Yen: Initially, we had to deal with just our internal IT folks being very skeptical. A lot of the
claims, "30 to 300 to 400 times faster in performance," "you’re only going to need a quarter of a

5. DBA," were the first two items where a lot of us were a little skeptical, myself included, but the
performance has really proved itself.
Aside from that, we have to look at it more realistically. How do we implement a system like
this? A lot of it has to do with changing the data loads, and that, in and of itself, takes a lot of
time. That's one of the things that's always going to take a lot longer than we thought, and it
would be a lot more challenging than we had initially anticipated.
The one thing that I'm proud of is that our team was able to conquer all of these hurdles, and also
we had a great partner in Vertica. They were there with us in the trenches, even though we were
the first retailer and we had a different use case than all of the other previous clients and
customers that they had.
We took a chance with them, they took a chance with us, and it worked out. We were able to
prove that their software works on a multitude of different use cases. As a retailer, we have a lot
of updates with our data. This was three years ago. Their clients then, lot of the telcos and banks
were just loading data, not really doing a lot of updates with it. They were doing a lot of queries
with it and it was coming back fast, but not really transforming the data all that much. So we had
a lot more use cases like that and they were able to come through for us.
Gardner: What about the future? Do you have a sense of taking this powerful capability and
pointing it in new directions, perhaps into supply chain, the ecosystem of partners, perhaps even
into internal operations? What's the next step?
Exciting times
Yen: It's actually exciting times, because Vertica has proved itself so well. It's also very cost-
effective. One of the projects that we're working on right now is that we have a relational
database for our MRP system. It's more of an ODS reporting system. We’re actively converting
the ODS system, which is actually a replicated database of the relational database, into a Vertica
database. We're able to kind of replicate, mimic the native database replication scheme on the
relational side, and use Vertica for it.
It's a use case that we were a little skeptical about in the beginning. Could this be done in
Vertica? We thought, the payoff would be great if we could do this on Vertica, the speed for
performance, the storage footprint, would be amazing. So far, it's turned out very well for us.
We’re still in the middle of it, but all things point to success there.
Gardner: Well great. I am afraid we’ll have to leave it there. We’ve been learning about how
Guess Inc. has been using HP Vertica to both speed up and better distribute its big-data analytics
capabilities.
