Traveling Auditor
  
Would you watch a Broadway musical about an auditor who traveled from small town to small town, reviewing the books of local barbers and school band directors? No, huh? Back to the drawing board for us. Maybe we can repackage the melody to "Oh! What a Beautiful Depreciation" for another show.
In real life, a traveling auditor is just what the name describes. (But they don't hop the Silver Eagle Express from Des Moines to Omaha, like in our musical; they tend to choose the thoroughly unromantic options of planes and cars instead.) Traveling auditors review a company's financial statements and check them for accuracy. They also provide advice for setting up structures to protect data and ensure reliability.
They are "traveling" because they aren't permanently employed by the company in question. They are outside advisors, brought in by the company to double-check what their in-house accountants have done. Then, when that's done, it's back on the Silver Eagle Express and on to the next town.
