It's with respect to the management of staffing, provisioning, adequate supplies and assistance.
'Efficient management of a company's supplies is the responsibility of purchase managers and supplies, who are responsible for choosing, contracting and managing the provisions which guarantee the sufficient supplies of material goods and services which are required. Consequently, staff who are duly equipped and adequately motivated to continue are required.'
'The function of adequate provisioning begins with the selection process of suppliers or providers in the supply chain. After the initial stage, it's necessary to negotiate with contracts which work towards continuation objectives, to maintain continual incoming supplies of material goods which have begun to be used up and other goods or commodities which could have been used up or finished. The supply chain process aims to be punctual within appropriate pricing conditions and profitability.'

(ES: "La gestión eficaz de los suministros de una empresa es responsabilidad de los gerentes de compras y suministros que tienen que ocuparse de buscar seleccionar, contratar y gestionar los proveedores para garantizar el abastecimiento de materiales y servicios que se necesitan. Como consecuencia de ello, se requiere personal debidamente capacitado y suficientemente motivado para seguir en la cadena de suministro.")
