ESE-2019 Prelims Ethics & Values in Engineering Profession


While Engineering Marvels make lives of people better, accidents and disasters pose challenges to engineers in edition to affecting the public.  A deeper investigations of these mishaps leads to pointing the finger on the conduct of engineers, their inability to either identify or resolve the identified moral  issues in an appropriate manner. While sometime this inability can be traced to incompetence, majority of the times it turns out to be the pressure by the management whose priorities differ from that of the professional engineers. The engineer is pressed to handle these two factors along with his/her own ignorance or arrogance, to make sure that public is not victimized.

Therefore, there is a need to expose the engineering students to the ethical  considerations of engineering problems in edition to the technologies and standards taught in engineering education. While curriculum focuses on external engineering aspects in terms of meeting standards, facilitating practice of ethical conduct focuses on inner engineering and inculcates and nurtures the sense of responsibility and accountability in the engineering graduates. This further promotes integrity in the qualified engineers to conduct profession in the most ethical manner. This dimension of engineering education that gives inputs  on the ‘third dimension’ of engineering, viz., values of engineering profession can be termed as engineering aptitude.

ESE-2019 Prelims Standards & Quality Practices in Production, construction, Maintenance and Services


The key factors that are responsible for survival and performance excellence of any industry are customer satisfaction and return on the capital invested. This applies to both manufacturing and service sectors. To avoid intra country and inter country comparisons for products in the market, there arises a need for uniformity in standards, established codes  and procedures for meeting customer expectations. Hence the standards and quality practices play an important role. For this requirement to be met ISO is ensuring equality in the standards of products and services.

ISO is striving relentlessly to institute quality policies to shape the behavior and establish core values in an organisation and therefore contribute to corporate policy, control charts. Acceptance sampling systems, continuous improvement techniques are used by every organisation throughout the world to improve product quality service quality and reduce cost. The most effective use of these techniques depends upon they being understood by production and inspection supervisors by engineers and by managements.

Rules and regulations for improving quality in all disciplines was documented by quality  guru’s in the quality philosophers, which are advocated through out the world.

We tired our level best to give the best possible theory with relevant objective questions to help the student in their ESE preparation.
We welcome the suggestions by readers with respect to content and questions.
