The term deficiency refers to any element, thing or situation that is not perfect or that has some type of imperfection, lack or defect.
That or that which is not perfect
The deficiency or the quality of being deficient means that an element, a person or a certain situation are not completely efficient, therefore they are erroneous or failed. Impairment can apply to both things and people, in which case it can sound like a very pejorative and derogatory term, considering that individuals possess different capabilities or 'efficiencies'. This is especially true when it comes to people with disabilities, who in some settings are often mistakenly regarded as handicapped.
When we speak of deficiency, we are pointing out that, for example, a certain object or element cannot fully fulfill the functions that have been conferred on the origin, or for which it was built. In this sense, it is very common to apply the notion of deficiency on elements or things that are related to current technology. Thus, when such phenomena stop working or cannot do it directly, they are considered defective or deficient. This is very common with everyday devices and not so much with scientific research machines that must be very accurate and reliable.
Repair or replacement of equipment that does not work
It is common that the constant use over time of some equipment and devices generates natural wear and tear on them that will make them start to work more slowly, in a poor way, let's say. Meanwhile, faced with this situation, we have several alternatives, replace them with the same new equipment, or, failing that, repair what is causing its deficiency and thus restore operability.
When we begin to confirm that a horse is not working as usual, the ideal is to take it to a professional who will check it and tell us what the best solution is: fix it or directly replace it. Because many times the repair can be more expensive than the replacement with a new equipment.
We commonly call technical service to those places and professionals that are exclusively dedicated to the revision and repair of artifacts, machinery or devices. Surely they will ask us to leave the article in question to review it and in a few days they will summon us to provide us with information regarding their problems and the costs involved in their repair.
Employee who does not perform tasks correctly
When we notice the presence of deficient qualities in a person, the term is usually applied in the workplace to indicate that such an individual does not perform their tasks and activities correctly. Then, it will be said that this or that employee performs a poor job.
Lack of preparation to deploy the position, studies, lack of interest, are usually some of the most common causes that are identified when there is a deficiency in an employee.
The first two are easy to repair since the employee can be urged to take a special training course, meanwhile, disinterest is an issue that the company will not be able to resolve per se.
The inefficiency of an employee is an essential issue to be resolved by the company that has hired him because otherwise such issue will negatively impact the productivity of the company.
Mobility and mental deficiencies
On the other hand, when the term is applied to people, it may be referring to the deficiency that a person has regarding their health, the most common being mobility and mental.
The first involves a neural problem that directly affects a person's movements. Those who suffer from this problem cannot move or coordinate their movements in a compliant way.
Meanwhile, mental deficiency implies a deficit in cognitive capacity, which usually arises in childhood, and which prevents the person suffering from it from behaving and learning in a normal way.
This term is not usually found in other issues as long as it is talking about people. However, some specialists in matters such as psychology may use it from time to time to refer to specific shortcomings or shortcomings of an individual. For example, it can be said that a person has emotional deficiencies, that is, that he cannot relate to others or express his sensations, feelings in the correct way or as others do.
