There's apparently a shortage of analytic talent to fill these new "yield optimization scientist" and similar positions created by ad agencies. Since I get lots of resume each week from stellar, perfectly qualified candidates who want their resume posted on DataShaping, and few if any request from hiring managers looking to fill these positions, I think that

Why Visualization makes or breaks BI

There’s a lot of buzz around BI semantics and until recently quite a few analysts have been caught into the world of data definitions and Cubes. For obvious reasons: the current state of BI is hard to use and has required companies to scale up on report writers and other personnel with technical-to-business “translation” skills.

Billions of dollars wasted each year in people spending their time applying for jobs. Here's the fix.

This has changed for good, and based on Western countries that have experienced  a 10% unemployment rate for 40 years in a row, here's the problem and solution:

  • In these countries, unemployment after graduating can last for more than a year (including for analytic degrees), and the first secured position might…
