Article (academic language) to benchmark procurement software for a multinational company

To write an article where you compare the procurement software for multinational company with 5 business units wordwide. The goal is to benchmark a top 3-5 procurement software that will enable Headquaters to monitor and observe procurement activities in Business units through 1 system in the next functions: 1. Spend analysis 2. Supplier management (Managing the information and performance of the Group’s global suppliers) 3. Contract management (Managing the lifecycle and sharing global contracts) 4. Sourcing (End-to-End online management of RFx process with collaborative working between HQ and BU teams) 5. Savings tracking (Monitoring and tracking savings progress in the different stages from all global and local initiatives) 6. Procurement initiatives (Managing and monitoring the progress and results of global and local procurement initiatives) 7. Procurement planning (Developing of group wide procurement plans and defining targets for all categories ) The benchmark should give clear analysis based on the cost/investment, support of the functions and total cost/benefit for the company. I expect at least 1 cloud and 1 fixed procurement system in the comparison. (please include references) Any other details can be discussed via mail.
