The second area, application coverage, looks at the test process from other directions -- typically, the percentage of the requirements that are "covered." One common application coverage tool is a traceability matrix -- a list of which tests cover which requirements. Typically, test case management software records all the planned tests and allows testers to mark that a test case "ran" for any given release, which allows management to determine what percentage of tests were "covered." This is a sort of "quality assurance" look at the test process, which should ensure that each part of the application is covered, along with a management control.
 Use Smartsheet to track the schedule and results of planned, current, and completed tests. Share the schedule with your team and collaborate on the details in real time, in one central location. Whether you’re running manual or automated tests, Smartsheet’s broad range of views – Calendar, Gantt, Card, and traditional Grid – allow you to manage progress the way you want. Organize test results with hierarchy and use comments to keep work in context.
The automatic telephone switchboard was introduced in 1892 along with dial telephones.[35] By 1929, 31.9% of the Bell system was automatic. Automatic telephone switching originally used vacuum tube amplifiers and electro-mechanical switches, which consumed a large amount of electricity. Call volume eventually grew so fast that it was feared the telephone system would consume all electricity production, prompting Bell Labs to begin research on the transistor.[36]
BPAs can be implemented in a number of business areas including marketing, sales and workflow. Toolsets vary in sophistication, but there is an increasing trend towards the use of artificial intelligence technologies that can understand natural language and unstructured data sets, interact with human beings, and adapt to new types of problems without human-guided training. BPA providers tend to focus on different industry sectors but their underlying approach tends to be similar in that they will attempt to provide the shortest route to automation by exploiting the user interface layer rather than going deeply into the application code or databases sitting behind them. They also simplify their own interface to the extent that these tools can be used directly by non-technically qualified staff. The main advantage of these toolsets is therefore their speed of deployment, the drawback is that it brings yet another IT supplier to the organization.
