Robinson De Jesús spent over fifteen years in field of Internal audit; as a Corporate Auditor inside Kraft Foods, Merrill Lynch, and Moody's, learning to find risk before it found you, as well as a software consultant and management team member for an audit management solution, helping organizations improve their audit processes. Long before that, he learned the same lesson watching his father cut hair in a Bronx barbershop, and before that, landing in New York as a child from the Dominican Republic with no English and no map. One Line at a Time argues that none of those experiences were separate. They were the same training, repeated in different rooms.
This book translates the methodology Fortune 500 companies pay millions to build internally (risk assessment, variance analysis, control implementation, workpaper documentation), into a language and tools a small business owner can use the same day. Each chapter follows the same structure an auditor would recognize: a finding grounded in real experience, the framework it produces, and a self-audit workpaper the reader completes on their own business or career.
The book draws its frameworks from unlikely places (a barbershop, a bodega, a JFK arrivals hall, a Wall Street trading floor), and treats all of them as legitimate sources of professional methodology. It is written for the barber, the contractor, the solo tax preparer, and the auditor at any level who has ever sensed that the discipline they need already exists somewhere, just not where they were told to look for it.
