Quality assurance (QA) is a way of preventing mistakes and defects in manufactured products and avoiding problems when delivering solutions or services to customers.

The Interstate Commerce Act of 1887 is a United States federal law that was designed to regulate the railroad industry, particularly its monopolistic practices.

The reason that the Interstate Commerce Act required that rates be published was to avoid secret rebates and similar deals. Until then, big shippers would demand rebates from railroads, which would in effect reduce their shipping costs without letting competitors know. This is anti-competitive.

Hence, the Act required that railroad rates be "reasonable and just," but did not empower the government to fix specific rates.
