On a project, can the information clerk and the material clerk be the same person?

The documenter and the material clerk of the project cannot be the same person. According to the relevant information inquired, the nature and responsibilities of librarians and materials engineers are different. Although there are some overlapping parts, it is a good guarantee that different people are responsible for project management and operational efficiency. The documenter is usually responsible for the management and maintenance of project documents, records and archives, while the material clerk is responsible for purchasing, picking, warehousing, storage and inventory management. Therefore, in order to ensure the management and operation efficiency of the project, it is best to recruit librarians and materials clerks respectively. If there is a shortage of staff, we must also ensure that the work of the two positions is properly arranged.
