01-01Why Do Forecasters Keep Forecasting?

I found this article quite interesting, a wide range of investment advisors missed the forecast for the growth of the S&P stock market index in 2013, all of them by a huge amount (a range of being off by -53% to -109%)!  This shows how incredibly difficult forecasting even one year out can be, in spite of these companies having entire teams of experts constantly studying every machination of the underlying data that affects the stock market including economic factors, political climate   and more. In fact, if forecasters at many retailers were off by so much on their overall company sales growth forecasts, they would likely be sacked or at least pummeled with a bag of oranges in the garage one dark evening!

Why is this article so important? Because there has been tremendous hype around the power of predictive analytics to steer the business. The reality is that forecasting is an incredibly hard job, regardless of the overall intelligence, toolset, access to data and experience of the team. Does this mean we should give up on forecasting and using advanced methods to predict future outcomes and behaviors? No! However, it does imply that forecasting should be fluid and adjusted, sometimes rapidly, in response to changing external factors.

All of this begs the question, how can someone do this? In my opinion, it points back to visual analytics, dedicated teams of business analysts with clear missions and good data management and warehouse practices with an agile approach, so that major misses can be caught, reviewed and corrected mid-course.

I created my own summary dashboard of the growth forecasts (image above.) Imagine if you were a client of these firms and you were told in late 2012 that stocks would lose money in 2013 (Wells Fargo and UBS), so you buried it all back into low-yield bonds! In the words of Warren Buffett, “Buy when everyone else is selling.”

2014 US growth forecasts of Business Intelligence vendors

There are many ways of measuring the growth of business intelligence vendors. One approach of interest in the era of self-service analytics is to measure the growth in web search volume. Derived from web search volume data from Google, the following analyses can serve as a useful reference to understand which companies/products are growing in popularity and which may be falling out of favor.

The estimates in all of the following analyses are based on simple web search volume indices from the United States through the end of November, 2013. Using historic search volume data, forecasts were built for each company/product and growth rates for 2014 were derived from these forecasts.

I would group these companies into three categories
fast growers- Tableau, PowerPivot, Qlikview, BIRST and GoodData;
the growers- Spotfire and Microstrategy,
and mature products- Oracle BI, SAS, Cognos, SPSS, SQL Server, Actuate and Business Objects.

A spin-free explanation of data warehouse versus big data

"It should be no surprise that many Hadoop (big data) systems sit side by side with data warehouses. These systems serve different purposes and complement one another.”
- Joint quote from CTO of cloudera and General Manager at Teradata

big-data-example-versus-data-warehouse

As you may have heard, big data is all the craze and at the top of the technology hype cycle! In my opinion, it is thoroughly confusing business execs, overwhelming IT teams and being used to market a massive range of new startups, sometimes justifiably. The reality is that big data will most likely NOT replace your data warehouse and the data scientist will most likely NOT replace your business analyst teams.

In a recent white paper,
