Continuous minor improvements and an increase in the number of projects aimed at improving efficiency and reducing costs may lead to the establishment of an independent research and development department. The Lean approach contributes significantly to improving production efficiency, a major part of which is reducing errors caused by human inattention. These must be observed, noted, and then proposals made and plans drawn up to eliminate them. Employees who use the machines and the engineers who oversee the production and quality assurance processes play a huge role in all this. Melecs' management believes that a company is only as good as the developments it can make itself. They encourage their employees to ensure that the company is not dependent on suppliers of production lines and equipment, but to implement their own developments on a smaller or larger scale. This saves a lot of time and money and significantly increases the company's adaptability and flexibility. All of this is also in their best interests, because if they do not produce efficiently enough and cannot deliver the right quantity on time, the customer will not wait, but will look for another supplier.
