For each category, the Public Procurement Regulatory Authority (PPRA) requests a list of commonly procured commodities, specifications, unit of purchase, and related brand names from various procuring entities, as well as the outlets where these things are procured.
Using this data, a complete questionnaire outlining the various items is then created and given to the selected outlets by famous researchers hired by PPRA to collect data.
The data gathered from the outlets was evaluated in order to arrive at an average pricing for each item, taking into consideration the various types available on the market.
