Engineers apply techniques of [[engineering analysis]] in testing, production, or maintenance. Analytical engineers may supervise production in factories and elsewhere, determine the causes of a process failure, and test output to maintain quality. They also estimate the [[time and motion study|time and cost required to complete projects]]. Supervisory engineers are responsible for major components or entire projects. Engineering analysis involves the application of scientific analytic principles and processes to reveal the properties and state of the system, device or mechanism under study. Engineering analysis proceeds by separating the engineering design into the mechanisms of operation or failure, analyzing or estimating each component of the operation or failure mechanism in isolation, and recombining the components. They may [[Risk analysis (engineering)|analyze risk]].<ref>{{cite journal | last1 = Baecher | first1 = G.B. | last2 = Pate | first2 = E.M. | last3 = de Neufville | first3 = R. | year = 1979 | title = Risk of dam failure in benefit/cost analysis | journal = Water Resources Research | volume = 16 | issue = 3| pages = 449–456 | doi=10.1029/wr016i003p00449 | bibcode=1980WRR....16..449B}}</ref><ref>Hartford, D.N.D. and Baecher, G.B.

Many engineers use computers to produce and analyze designs, to simulate and test how a machine, structure, or system operates, to generate specifications for parts, to monitor the quality of products, and to control the efficiency of processes.
