which branch of the service was once known as the revenue marine
United States Revenue Cutter Service The United States Revenue Cutter Service was established by an act of Congress (1 Stat. 175) on 4 August 1790 as the Revenue-Marine upon the recommendation of Secretary of the Treasury Alexander Hamilton to serve as an armed customs enforcement service. As time passed, the service gradually gained missions either voluntarily or by legislation, including those of a military nature. It was generally referred to as the Revenue-Marine until July 1894, when it was officially renamed the Revenue Cutter Service.
Service–profit chain The service–profit chain is the central concept in a theory of business management which links employee satisfaction to customer loyalty and profitability. It was proposed in an article in the Harvard Business Review in 1994 by James L. Heskett, Thomas Jones, Gary Loveman, W. Earl Sasser, and Leonard Schlesinger,[1] and was later the subject of the book The Service Profit Chain – How Leading Companies Link Profit and Growth To Loyalty, Satisfaction and Value, published in 1997 by three of the same authors.[2]
