WALLY'S DOGS
Discover Why the P&L Changed—and Where to Start Asking Questions
A short, practical book for people who run the work—and still have to explain the numbers.
Not an accounting textbook.
You got the P&L.
Now someone wants to know why.
Wally's Dogs shows you where to start.
Follow the Money
Start with the simplified statement. Learn what can move each line. Then investigate the result instead of guessing at it.
What happens if Wally changes Price or Volume?
Move a slider. Watch the statement.
| Line | Actual |
|---|
In this guided example, Material moves with Volume while Labor and Manufacturing Overhead remain fixed.
The book teaches. The website lets you work with it.
Change familiar drivers one at a time, then use Sandbox when several things move together.
Open Simulator →Search the same financial vocabulary used in the book when a term gets in the way of the business underneath it.
Open Quick Reference →For people expected to understand the numbers while running the work.
You know the operation. Now the numbers are part of the job.
You are expected to explain results without a finance degree.
Price, Volume, Usage, Labor, Overhead, and Mix are already part of your world.
You need useful questions faster than you need accounting vocabulary.
