principles of completeness and simplicity
The number of selected indicators should be as small as possible, concise and clear, there should be no strong correlation between indicators, and too much information inclusion and coverage should not appear. The connotations of indicators overlap.
Principles of Objectivity and Comparability
The selection process of indicators should not be affected by subjective factors as much as possible. Qualitative indicators are greatly affected by subjective factors, which can easily lead to cognitive bias. Quantitative indicators are easy to quantify and measure, so quantitative indicators should be selected as much as possible.
Reconfigurability and Extensibility Principles
The evaluation index system must not only change in quantity, but also in content. Users can modify, add or delete the indicator system according to different needs, and further specify evaluation indicators according to specific situations.
risk minimization principle
There are certain risks in the operation of the supply chain, which must be carefully considered to avoid or reduce the overall operation risk of the supply chain as much as possible.
Violation of the above principles will greatly affect the efficiency of the supply chain. Violating the principle of core competence and total cost will make it difficult to meet the requirements of the "external economy" of the supply chain. Violation of the principles of agility will fail to ensure rapid response to market opportunities, while ignoring the principle of risk minimization will hinder the operation of the supply chain. poses a huge hazard. Therefore, when selecting a supplier, the above four basic principles must be fully and seriously considered.
Establish an evaluation index system for helmet manufacturers
Due to many influencing factors, the evaluation and selection of suppliers is more complicated. According to the three major factors followed by the supplier evaluation index system, select indicators that are easy to measure and collect data for evaluation and selection.
By setting up a benchmark helmet manufacturer, the company sets an example for other Bicycle Helmet manufacturers and helps suppliers improve their performance. To establish a benchmark supplier, we must first measure the main performance value of a good supplier, and then provide this information to each supplier so that other suppliers can find their own gaps, organize and improve their management level.
