|Methods and techniques|
The zero defect method assumes that one can aim to eliminate deficiencies entirely thanks to proper organization of processes, training of personnel, and maintenance of infrastructure.
Zero defects idea
This process was used for the first time in the armaments industry, where it worked perfectly well. Later, this method was popularized in civil industries. It gave rise to a number of methods that combine management principles and statistics.
The zero defect method is a process aimed at eliminating errors, defects that take place in enterprises. Each organization aims to produce a product of the highest quality that meets the expectations of customers. The value of resources and skills that the company had in the past does not necessarily have to be reflected and useful in the future. "However, the value of resources and skills should be considered mainly in the context of their impact on achieving adequate economic results."
Zero defects in practice
In practice, the company's specific resources and skills should contribute to better results than competitors. If we assume that in a specific business activity based on the production of products or provision of services there are such elements as:
- the purpose of the activity,
- incurred expenditures related to the means of performing tasks,
- results of operations,
The time in which expenditures are incurred and the results are output, we can assume that the effectiveness of this activity will be expressed in the degree of achieving the goal as well as the mutual relationship between the results and expenditures at some time.
Current problems of zero defects
In the present conditions of the organization's functioning, it is not enough to research and assess the effects of work obtained by employees at a given time, but it is necessary to study the conditions affecting these results and the analysis - the cause and effect of changing factors. It is necessary to consider and analyze the given situation, which was the reason for such and not other company results, regardless of whether it concerns success or defects in the production process. It is assumed that the employee is able to produce a certain thing flawlessly only the first time. However, attention should be paid to factors and tools that are needed by the employee in the production process. "The effectiveness of work depends on many factors that can be divided into two basic groups:
- external factors in relation to the enterprise,
- internal factors.
When comparing the result achieved with the intended one, it is worth asking yourself the reason for this condition. Sources of irregularities may be at the stage of accomplishing the goal as well as earlier stages, including also at the stage of formulating the goal.
To capture the errors you have to follow the entire process. "The action is then rationally rational when it is consistent with objectively existing conditions and means, i.e. with objective truth from a given range of objectivity." 3 The causes of defects are also imperfections of the process, and among them can be mentioned, for example: erroneous resulting from mistakes mistakes made by inadvertently. To eliminate mistakes, employees should be encouraged to pay more attention to their work, so that new similar defects do not arise.
The Zero Defects method belongs to the group of methods used in the organization in order to eliminate all kinds of errors, e.g. production errors, as well as to improve quality. The improvement of the quality of work as well as the quality of the resulting products contributes significantly to eliminating all kinds of defects in the production process.
