Top 5 Takeaways from INFORMS 2012 Business Analytics Conference

Rob was a Guest Blogger for the INFORMS Analytics 2012 Conference.  This was originally posted on the Conference Blog. 

As expected, it was a great conference with valuable presentations and plenty of opportunities to network with professional colleagues.  After a day to reflect, here are my top 5 takeaways (not necessarily in order).  Hopefully they will be useful to both experienced analytical professionals and executives, and those just starting the journey.

(1)   Google Insights for Search
Hal Varian, Google’s Chief Economist, gave a compelling keynote that made great use of this free tool.  Check it out if you haven’t done so already.  It’s a great way to identify market trends based on search frequency.  The data goes all the way back to 2004, and you can download the results to combine with other data sources.

(2)   It’s not just about the analytics
Congratulations to TNT Express, winners of the 2012 Edelman Award.   My biggest takeaway from their presentation had nothing to do with their network optimization models.  Rather, it was how they built an entire optimization “ecosystem” centered on their GO (Global Optimisation) Academy.
  • “(In addition) to adopting OR tools, TNT Express has teamed up with the Tilburg University/TiasNimbas Business School (Netherlands) to create a two-year management development program in transportation network optimization. Called the GO Academy, the training has been delivered to more than 150 managers from TNT since 2008.”
Lots of companies have advanced analytical capabilities, but TNT have added huge value to the organization – and set a great example for other companies -- through leadership, education, training and change management.

(3) The role of Analytics in Decision-Making
We’re always looking for better ways to describe what we do and how we add value through Analytics, and I thought a few of the speakers had particularly interesting angles.
  • Thomas Olavson of Google described his team’s role as “replacing intuition with data-driven decisions”.
  • Colin Kessinger of End-to-End Analytics reinforced the role of leadership.  “Math supports the decision-making process, but the math doesn’t make the decisions”.  Don’t expect an analytical model to give you “the answer”.
  • Both Colin and Glenn Wegryn of P&G focused on visualization & interactive decision support.  According to Colin, “This is what gets you a seat at the executive table”, and Glenn provided the evidence when he described the weekly “immersive business reviews” for P&G’s executive team (with a great picture of the huge hi-def screens that surround the conference room).
  • Focus on the “so what” or the “why” – not the “what”.  Reports are a dime a dozen.  How are you going to help drive better decisions?
  • A neat quote from Glenn Wegryn:  “We bear gifts - in the form of rational business insights”.  (In my words, "Geeks bearing gifts" -- OK, that's a really bad pun...)

(4)   Simpler is Better
The simplest approach that solves your problem is usually the best one.  Several speakers hit on this point in different ways.
  • There is “no correlation between analytic complexity and business value”, according to Glenn Bailey of Manheim.
  • Chris Fry of Strategic Management Solutions paraphrased Einstein – A model “should be as simple as possible, but no simpler”.
  • Before you jump into a big, complex analysis with expensive 3rd-party software, make sure you really understand the problem you’re trying to solve.  Colin Kessinger advises that if you can’t build and understand a prototype in Excel, you don’t really understand the problem and you’re not likely to be successful with a complicated off-the-shelf software solution.
  • Thomas Olavson echoed the sentiment that “small steps lead to big wins”.  He favors analytical building blocks and rapid prototypes, and cautions against looking for “grand unified theories”.

(5)   50 Minutes with the 5 minute analyst
It seems only appropriate to make the 5 Minute Analyst my 5th highlight.  In a very interactive conference session, Harrison Schramm of the Naval Postgraduate School shared some fun and thought-provoking “toy problems”.  Be sure to check out the 5 Minute Analyst column in Analytics Magazine.  The most recent column is available here.

Let me know your thoughts.  It's been fun being one of the Conference Bloggers and I look forward to continuing these interesting discussions.  Until next time...

So Much to See, So Little Time...

This is the first of several posts as a Guest Blogger for the INFORMS Analytics 2012 Conference.  It was originally posted on the Conference Blog.
I can't wait to get to Huntington Beach and the INFORMS 2012 Business Analytics Conference.  I'm looking forward to connecting with colleagues and friends, both old and new.  And this conference is one of the best "idea generators" I've ever found.  I always come back with pages full of ideas (most of which I unfortunately never pursue!).

If you're anything like me, the biggest challenge with any good conference, like this one, is deciding which presentations to attend.  I've been attending this conference for about 10 years, and the presentations seem to get better every year.  But that only makes it harder to decide which ones to see.  I spend most of my time doing Supply Chain work, but I'm often just as interested in topics outside of the Supply Chain tracks.  In fact, there's hardly a time slot without two, three or even four presentations that I'd really like to see.  It certainly helps that we can see the presentation slides in advance (thank you INFORMS!).  They're a good (not always great) indicator of presentation quality.  Clear writer = clear speaker?

Here's an optimization problem to ponder.  Wouldn't it be great if each attendee could rate each presentation in terms of likely interest, and then have a scheduling algorithm create a schedule to maximize the total utility, i.e., people get to see the most presentations they’re interested in?  I know that might wreak havoc with the track structure.  In a simpler scenario, you could maintain the integrity of the tracks (which presentations go in which tracks), but just vary the scheduling of tracks and of presentations within tracks.  What do you think?

Rob Ende Guest Blogging at INFORMS Business Analytics Conference

INFORMS_2012_Conf_HeaderI am very excited that I've been selected as a guest blogger for the INFORMS 2012 Conference on Business Analytics & Operations Research.

The conference takes place April 15-17 in Huntington Beach, CA, and is the leading venue where world-class organizations showcase the strategic use of business analytics and O.R.

The conference blog can be found here, and the blog will replace the conference home page once the conference begins.  I will also mirror my posts right here on REanalyze This!

In addition to taking in some great presentations on the success of Business Analytics in areas such as Supply Chain and Forecasting, I will be co-facilitating a discussion group on best practices in spreadsheet modeling:
  • Garbage In, Gospel Out?  Join Rob Ende, CEO of REanalyze Inc. and SPRIG President Rick Carter, CEO of Equation, in a discussion of tips and tricks on spreadsheet design, development and auditing to prevent errors, reduce risk and ensure quality results.

Please check back for conference updates starting April 15.  Until next time...
