Abstract: A method and system for controlling procurement systems where tender review process is by selecting external/internal reviewers randomly and by managing at least three levels of reviews. The method comprises collecting a tender information by an application server; collecting the bids; and collecting reviews at each level and transmitting the reviews to the next-level reviewers. The reviewers are selected from a reviewer register for each review level. The first-level reviews are transmitted or kept confidential as per entity preference to the second-level reviewer devices and the second-level reviews are collected within a limit period of time and simultaneously. The second-level reviews are collected from the second-level reviewers and transmitted to the third-level reviewers. The system may analyse the collected reviews and select the winner of the tender based on reviews collected.
