cant investment in making the unparalleled analytical and data management
capabilities developed over 30-plus years available to almost anyone with a
problem to solve in business, science, or government. With recent products
such as SAS Enterprise Guide and the SAS Add-In for Microsoft Office, SAS
has never been more accessible or flexible. These products provide user-
friendly interfaces and wizards to maximize the heavy-duty capabilities that
SAS has long provided to gurus!

Data, Data Everywhere —
But Not Where I Need It!
The glamorous side of business intelligence and data analysis is all the gee-
whiz reports, graphs, and impressive statistics you can present. (It must be
true because my p-value says so! And don’t worry if you don’t know what a
p-value is right now. That will come later.) The surprising secret of actually
arriving at good results for decision-making is the huge amount of time that
many people spend accessing, organizing, and preparing their data for a par-
ticular analysis. We’ve found a common theme in our visits to more than 50
major companies: the massive amount of resource and rework time spent on
the data preparation aspect of business analytics.
