অভিযন্তা এজনে পৰীক্ষণ, উত্পাদন আৰু তত্বাৱধানত [[অভিযান্ত্ৰিক বিশ্লেষণ]]ৰ বিভিন্ন পদ্ধতি ব্যৱহাৰ কৰে। বৈশ্লেষিক অভিযন্তা সকলে উত্পাদন অধীক্ষকতা কৰে,প্ৰক্ৰিয়াৰ বিফলতাৰ কাৰন নিৰ্ণয় কৰে আৰু বিভিন্ন পৰীক্ষণৰে গুণমান বজাই ৰাখে। পৰ্য্যবেক্ষক অভিযন্তা সকলৰ দায়িত্বত গুৰুত্বপূৰ্ণ অংশ বা সম্পূৰ্ণ প্ৰকল্পতো থাকে।
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 re-combining the components. They may [[Risk analysis (engineering)|analyse risk]].<ref>Baecher, G.B., Pate, E.M., and de Neufville, R.

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.
