Hughes (2005) considers five main steps when evaluating procurement practices: assessing needs, service design, supplier shortlisting, supplier selection, and supplier performance evaluation.
Várday (2005) also presents a simplified sequence of basic PP steps:
• preparation (determination of the object and quantity of the procurement task and decision about the needs);
• proposal (forming the contracting strategy, developing the tendering documents, assessing proposals and awarding the contract);
• execution (delivery including necessary education and invoicing);
• monitoring and analysis of the results (assessing whether original goals were met, collecting experiences and improving the procurement process).
