Engineering is a family that is made up of some members. In this family, each member has a specific function or function(s) to perform. In other words, engineering is a family that is made up of division of labour. The reason for the division is to make work easy and for maximum efficiency.

Engineering is a well respected area of study apportioned for men of greatness and societal changers. An engineer is change a maker. He makes effort to effect positive change wherever he or she finds himself/herself.

The wise old learned people understood the efficiency of dividing the engineering discipline into branches and did not hesitate in moving the motion.

The level of the function performed by each member of the family varies. Before further note on this topic, it is important to note that engineering team is different from branches of engineering. These are two related topics but they vary. They vary because the contents of the two topics are not the same.

In some market places or electronic repairing shops, we sometimes hear people that usually come to repair their electronic products call the repairer engineer. The person whom the title is addressed feel great when he hears people call him such name irrespective of the fact that he did not attend any tertiary institution. At the back of his mind, he truly knows he did not deserve such “big title” because he does not have any certificate to prove that. He can repair the electronic products based on his acquired skill in electronics. He is not a “real engineer” rather he is a member of the engineering family called craftsman.
In this topic, to be discussed are the real engineering team and it’s functions, and the limit of any member of the team.


For success to be achieved in the field of engineering, a professional engineer will work with other technically educated people (called members of the engineering family) to form what is known as an engineering family (Faluyi 1993), or engineering team (Oluka, Onwualu, and Eneh). Hence, members of the engineering team are:
Craftsmen; Technicians; Technologists; and the Engineers.

Among these classifications or divisions, the engineer stands out as the headman to direct and organize the activities of the other team members.


The craftsmen are the lowest in the engineering family. They are the first and the oldest members of the engineering family, because they existed before the modern-day engineers. The craftsmen did not attend any school and used their brains to make impact in the society. They are known as the ancient engineers. In the modern time, the craftsmen usually obtain Senior Secondary School Certificates or any certificate that proves that they are trained before they are allowed to work with professional engineers during finishing operations. Examples of craftsmen in our society today are the carpenters, mechanics , electricians, masons, plumbers, welders, and some others. Among all these examples, each of the members of the groups has their roles in making engineering works to be completed.

The roofing level of a building cannot be complete without the proper work of the carpenter. There is no way a professional engineer will climb on top of the building he is supervising to perform the function of craftsmen unless he had already acquired the skill before his engineering profession, apart from that, the person to perform the carpentry work becomes the carpenter. The carpenter must have been trained in carpentry to perform the job neatly. That is the reason craftsmen must be highly skilled to carry out their duties effectively.

The welders on the other hand have their own roles in engineering field. Metallurgical or Materials Engineers in most cases supervise them on the nature of the material they are to use to perform a task. It is after the strength of the material and the weldability have been ascertained that the welder will be called to perform his tasks. He acquires welding skills while the metallurgical or Materials engineers understand the structure-property- application relationship of the materials that the welder uses in welding.

There are many mechanics that are situated in many places where they repair faulty vehicles. They are doctors to most machines and automobiles. When cars develop faults, it is the duty of the mechanic to critically examine the cars and find out the problems with such cars and repair them at the end of the discovery. Good mechanics usually receive lots of works and they make good profits from the work they perform.


The technicians are the principal members of the engineering family. They play their own roles in making engineering family complete. As there are duties for a father, mother, and children in a family, so are the duties performed by the technicians as one of the members of the engineering family. The engineering family will not be complete without the technicians taking their place in the field of engineering. A professional engineer cannot be playing and dancing at the same time and that calls for the membership of technicians to help in solving some engineering challenges.

The technicians are usually the direct supervisors to the craftsmen in the engineering work places. They are the group that comes after the craftsmen from the bottom of the engineering family hierarchy. The qualifications of technicians are usually higher than that of craftsmen. They either have Ordinary National Diploma (OND) from technical college or polytechnic, or Full Technological Certificate (FTC).

The level of skill a technician acquires is usually more than that of craftsmen. The reason is because a technician supervises many craftsmen that work under his care. He needs to have knowledge on the diverse areas of work carried out so that he can correct any craftsman that makes mistake in carrying out the duties assigned to him.

In the construction sites, the technicians are there to supervise the functions being performed by the masons and the laborers that assist them. He is there to direct the masons on what they should do at any moment to get things right. In a layman’s language, these men are being addressed as contractors or the foremen in certain locations.


The technologists come third in the ranking of the engineering team from the bottom of the hierarchy. It can also be put that they are the second from the top of the hierarchical ranking after the engineers.

In terms of academic qualifications, the technologists have higher academic qualifications than the technicians and the craftsmen. In Nigeria for instance, a technologist is expected to obtain Higher National Diploma (HND) certificate from any engineering programme in Polytechnics or technical colleges. The curriculum of HND is designed for middle manpower development. In the engineering duties, they stand to supervise the technicians in the duties assigned to them.

Technologist acts as interface between the engineer and the technician. He sends the information derived from the technician to the engineer for the engineer to take note and sort out ways to solve any challenge encountered in any of the projects being carried out. For instance, if there is a construction work on going in a particular site, and the technicians are lacking some materials they need in completion of their own part of the work, the information is taken to the technologist who later takes it to the engineer to make provision of such materials.

In some locations, there is usually controversial argument between the technologists and the professional engineers. In some cases, the technologists want to be addressed as professional engineers without acknowledging the obvious existing ranking in the Engineering family tree.

For a technologist to qualify to be addressed as an engineer,he must obtain a higher degree or at least a post graduate Diploma in engineering in order to make up the deficiency inherent in his previous qualification. Without sentiment, the curriculum of an engineering programme in the university is designed to supersede that of same engineering in the polytechnic.


The engineers are the topmost level in the hierarchy of the engineering family. In terms of educational qualification, an engineer is expected to acquire a degree, Bachelor of Engineering (B.Eng) in any engineering fields from a recognized University. Some of the engineers go further to acquire higher degrees (Masters and PhD) in engineering. By training, engineers are equipped with creative minds for mathematical, analytical, and managerial skills, hence known as “problem solvers”. The engineer is the head in any engineering firm and gets day-to-day report directly from the technologist.


The family of engineering is a great one. Each group or rank compliments each other. Therefore, the family is incomplete when any is lacking.

However, it is wrong , unprofessional and amounts to forgery for anybody without at least a degree in engineering to arrogate the title “ENGINEER” to himself. If your highest academic qualification is O’Level or trade test, you remain a Craftman (an integral part of the engineering family). ND or OND as the highest qualification, you are a technician while a HND holder is a Technologist.

Craftsman – Technician – Technologist – Engineer is the great chain and should be respected. Together we shape the world.

  1. The composition of the hierarchy is properly enumerated, however, the flow of information or directives doesnt always religiously follow it. Sometimes, the variation could be due to difference in procedure of each division of the ingenious profession or the particular system/management culture of a firm.
    Usually; Engineers determine the solution to a confronting challenge or problem. This solution – which could be a physical product, an idea, or process – is called a technology.
    This technology is taught or passed to Technologists to operate and maintain. This is to prevent such product from premature retirement from the market while ingeniers concentrate on either further development of thesame technology or something superior to it. They can determine the servicability or otherwise of components, units, subunits, subsystems, or whole systems for repairs or outright replacement.
    Technicians are repairers and service personnel. They have the disadvantage of not knowing how the particular technology works, like technologists, but had possible recurrent issues identified and taught to them. They perform their duty on assignment from a superior – mostly technologists.
    Craftsmen have informal but no formal education. They learn specialized crafts and skills via apprenticeship schemes. Sometimes; these competences could be directly engaged by ingeniers, if such skills are needed. Certificate alone is not enough criterion to separate the various competences but the actual job they perform on the field. Being a holder HND is not what makes a technologist but they inability to be ingenious. Some technologists even have as far as MTech or PhD in Engineering.
    Certificate classification in Engineering is misleading as anyone can buy such certificates in the corrupt Nigerian system.
