Engineering is a very important discipline in the world of today. The importance of this area of specialization by many people is felt all over the world. In the current world we exist in, no country will succeed without the adoption of engineering practices. The importance of engineering in our world is numerous. This piece is just an introduction to the topic under discussion because splitting the topic in detail will occupy a large volume of text.

What is engineering? Engineering is a profession in which scientific knowledge and mathematics, gained through study, experiment and practice are applied with intuition or judgment to develop ways to use economically, the materials or forces of nature for the benefit of mankind. So many authors have given their personal definitions on their understanding of the word “engineering”. This word has turned the face of the earth to look more interesting and accommodating.

In the years back, there was nothing like electricity, which has made work easy and improves the standard of living. As of then, our forefathers were timid and live in the society that was not transformed through electricity. Because of the efforts of engineering, electricity has advanced and man utilizes it to achieve his goals in life.

In our homes, schools, offices, agriculture, automobiles, banks, security, and so many other areas, we observe the applications of engineering. In fact, you may not be able to read this article effectively without the underground works performed by engineers before the final manufacturing of the device. Engineering is a faculty that have been making machines with unique properties everyday. It is filled with experts that have great innovative ideas.

The Major Importance of Engineering

The importance of engineering to be elaborated on are related to six key areas. These six key areas are the importance of engineering in:

  • Agricultural;
  • Banking;
  • Automobile;
  • Educational;
  • Marketing; and
  • Health sectors.
Agricultural robots. These are used to automate agricultural processes, such as harvesting, fruit picking, ploughing, soil maintenance, weeding, planting, irrigation, etc.

Agricultural Sector

Agriculture simply put is the cultivation of crops and rearing of animals. This definition is as related to agricultural science. Due to the advancement in the agricultural practice, agriculture has developed a strong link with the field of engineering. It is because of the magnitude of this link that leads to the creation of agricultural engineering, which is among the branches of engineering. This engineering branch takes care of agricultural related affairs.

In our today’s world, hardly will you see a commercial agricultural farmer that does not make used of machines to increase the rate of his or her agricultural output. This importance added by engineering has really promoted the practice of agriculture all over the world.

There are specific kinds of fertilizers for specific kinds of crops. These fertilizers in most cases are products of chemical engineers. They look into the chemical constituents of the manure and used the result generated from the scientists to know which will have good effects on crops and go into their productions.

In the dry season, there is no rainfall, yet agricultural products are being supplied to markets where they are being sold to the consumers. The question is: how are these products made available irrespective of the fact that is usually no rainfall in the dry section of the year? Drilling engineers are among the people that make those products available as through the work they do generate water from beneath the ground. It is the water that is used to keep the crops growing through the irrigation system.

Banking Sector

Sometimes people argue on why engineers should be found in any bank. They do say that none of them suppose to be there because there is a big difference between the two disciplines. The fact remains that engineering is a course of men who can withstand pressure and a great test. Because of this, bank sometimes chooses graduates from this discipline to work with. That is why some engineers are found in the marketing department of various banks today. Banks are interested in who will give them what they want and not just who studied their related course in the tertiary institution.

Engineering plays fundamental roles in banking institutions of various societies. In a bank, there are many engineers that engineer the affairs of the banking activities. Without these engineers, the banks will not function effectively. Banks are advancing on a yearly basis and they have been demanding the services of the engineers (especially Software and Networking Engineers) to make the advancement unique. Engineering in banks has added a lot to the quality of services that banks render to their customers.

Let us start with the one every bank customer is aware of before going deep in the other area of the banking activities. Gone are days when bank cashiers count money with the manual process using their fingers. Today, the money is being counted within few seconds by money counting machines. Who manufactured those counting machines used in the banks for counting of money? The answer is nobody else than the engineers. That is to say that the money counting machine would not have been in existence if not because of the engineers.

What of the computers used by bank staff during their banking activities? Are these computers thrown from heaven for the banks to start marking use of them? No, at all because they are physically made through computer engineering and then supplied to the banks that make use of them.

Modern day banks cannot function without the use of durable bulletproof doors, to be protected from the hands of the armed robbers. The features of these kinds of doors are usually made of glass and some others steel. Metallurgical and materials engineers that deal on glass and steel are the people that test and confirm the strength of the materials used in the production of such doors so that they can resist the effects of bullets (bullet proof doors).

Importance of engineering in automobile sector.  The car used is an automobile.

People like to have mobile houses of their own if they have the money to make a purchase. Automobiles have helped in a great way to ease the stress being faced by the man from moving from place to place. These automobiles are into existence because the engineers came up with the idea and they succeeded in making it accessible to people all over the world.

What is automobile? According to Oxford Advanced Learner’s Dictionary, an automobile is a car. It is engineering that is being studied that gave birth to many designs of cars that are all over the world. Starting from the making of the cars from the scratch, mechanical engineering makes it possible. This is the category of the engineering field that first designs the shape of the car in question before the final production.

When it comes to the making of the engines of the automobiles, metallurgical engineers play their own roles as well. This is evidence on the importance of engineering in the beautiful world of the automobile. Metallurgical engineers make proper effort to find out the proper quality of alloys to be used in the production of the engine blocks before finally casting the engine of the vehicle. The casting of the engines of vehicles can be carried out using any convenient casting processes, especially investment casting process.

The author of this article who is a graduate of Metallurgical and Materials Engineering is currently developing a book which discusses the applications and importance of Materials Engineering in the society. This is a sound book that will serve as an eye-opener to people who want to know more about the engineering field.

The piston and the gears of cars are products of casting carried out by metallurgical engineers during car production. When investment casting is used to make these parts, high accuracy is obtained. But other casting processes can be used for the production.

The importance of engineering in our society made it possible for car owners to drive so many designs of cars each year. Someone may be driving Honda 2008 model and all of a sudden hear that the latest Honda of 2015 which has more advanced level has been produced by the company. What he does on hearing this is to sell his old modeled Honda and go for the new design, all centering on the importance of engineering in the society.

Educational Sector

Education is very important in the life of every intelligent individual, and it has been spiced up with the contributions of engineering. It will be boring without the presence of engineering in it. The works of the engineers are seen in all levels of education; primary, secondary and in the tertiary level. People on many occasions have got involved in debates based on the positive contributions of engineering in the education department.

Starting from the clothes that teachers and the lecturers wear to classes where they teach the students on the knowledge they need to acquire, the clothes would not have been made if engineering is ignored. That you as are a reader of this piece of write-up wear cloth on your body right now is a product of textile engineering field.

In various institutions of learning, it has been made compulsory that every school will have computers integrated as part of their academic study or curriculum. These computers being talked about are made possible because of the efforts being put by the computer engineers. Some higher institutions have air-conditioners installed in their lecture halls to make the students feel comfortable learning in a good environment. This machine that maintains a certain level of temperature in lecture halls and offices in educational institutions are all products of engineering.


What business does engineering have with marketing? Has engineering in any way contributed to the level of marketing activities in our society? The answer to the questions is yes. Engineering in totality has greatly impacted much in the marketing sector. Marketing is the action or the business of promoting and selling products or services. The promotions of services and products have been made possible as engineering continues to advance on the daily basis.

The internet has helped many businessmen in the marketing of products and selling some useful services to their customers. People sit with their computers and advanced mobile phones and promote their businesses through this channel. Presently, there are many websites created where people go and render services to get paid in turn for the work well done. An example of such website is the one called Fiverr. This is a website that has been a source of daily bread to people from different parts of the world. There are dozens of services being offered by sellers in that website including web and graphics designs, promotion of books and other tangible goods, application designs, sound cloud works, writing businesses, and so many others.

Because of the importance of engineering in the field of marketing, people can use their mobile phones, which are the products of engineering, to order for goods from other countries which get supplied to them within few days. Also, some business owners have hosted many websites on the web where they tell people all over the world of products and services they sell without the buyers visiting the location of the business company.

Health Sector

Health and engineering; any similarity? Do you think the two have something in common or does engineering have an influence on it? Beyond any reasonable doubt, the health department of every country firmly depends on engineering to achieve any of their goals in the health status of the patients being admitted to the hospitals. It is true that engineering does not have any business with the drugs being used in hospitals as that is the business of pharmacists, but, what about the other equipment used in the hospitals?

Let us start with the instruments which the doctors used whenever they are carrying out surgery. Do you think the materials of that nature are being produced by the doctors? No, because starting from the pattern making to the final finishing stages of such equipment are being carried out by the engineers. Examples of such instruments are the scalpel, surgical lamps, stethoscope, and so many others. All these instruments are made available to the surgeons with the help of engineering.

There are situations where the patients are not manually diagnosed by the doctors to find out the cause of a particular illness. In such complicated cases, the doctors use computers to find out the cause of such illness. These computers are being produced by the engineers who apply engineering principles to automatically detect problems in the human system.


Engineering as a profession is a major player in the twenty-first century. Engineering is a unique profession and it has been changing the face of the earth to good. The world is upgrading and seeing clearly because of the importance of engineering profession in our society. In this piece of write-up or essay, the author detailed out the importance of engineering as it relates to agricultural, banking, automobile, educational, marketing, and health sectors.
