This is a process where a purchasing organization undertakes to procure goods and services from suitable suppliers. Due to the high value of some purchases (for example buying a new computer system, manufacturing machinery, or outsourcing a maintenance contract) and the complexity of such purchases, the purchasing organization will seek to obtain a number of bids from competing suppliers and choose the best offering. An entire profession (strategic procurement) that includes tertiary training and qualifications has been built around the process of making important purchases.
