ABSTRACT
Organizations with well developed procurement processes have very prescribed mechanisms for ensuring clarity of the communication process between buyer and seller. In these organizations the specification will form part of a Material Requisition. The purpose of the material requisition is to convey information concerning material, equipment and/or services from the design department, or the person responsible for the technical aspects of a project, to the purchasing department. The material requisition is really a document that wraps up all the information required, to enable to invite suppliers to tender for the goods or services that require. Spares can comprise few categories: spare parts required for the operation and maintenance of a facility, and spares required as additional quantities as a contingency, say, during installation and commissioning. The data sheet is the most straightforward form of technical communication and it helps to minimize mistakes. The items are identified with catalogue type descriptions and any appropriate standard specification numbers.
