High Speed Steel * High Speed Steel (HSS) refers to any of a variety of steel alloys that engineers primarily use to construct machine tool bits and blades and drill bits for industrial power tools. Materials scientists can infuse this steel with differing percentages of elements to form a variety of HSS manufacturing alloy types. While all of these different types exhibit HSS’s characteristic resistance to high-temperature‚ the properties of each alloy will vary depending on the percentage of

SOFTWARE TESTING SOFTWARE TESTING Testing is the process of executing a program with the intent of finding errors. TESTING PRINCIPLES All tests should be traceable to customer requirements. Tests should be planned long before testing begins. The Pareto principle applies to software testing. Stated simply‚ the Pareto principle implies that 80 percent of all errors uncovered during testing will likely be traceable to 20 percent of all program components. TESTING PRINCIPLES Testing should begin
