These constraints force the company to adapt to its environment. This adaptation cannot be done without taking into account the human factor as a source of development because, unlike the material sources that are consumed by the company's activity, intangible sources also have the particularity of being a factor that is integrated into the product and service sold, that does not disappear, but on the contrary enriches the company's intangible capital through the cumulative effect of experience. 

Employees are encouraged to improve their knowledge, attitudes and skills necessary both to achieve the objectives of the organisation and those they are personally, to adapt to their environment and to perform their current and future tasks.

Training is considered one of the most effective human resources management tools, enabling companies to have a human potential that is constantly at the highest level of the skills necessary for the company to run smoothly.
