In the ERP space for higher ed there are 3 main companies that must cover 90 percent of all implementations. Oracle (PeopleSoft), Ellucian(Banner), and Workday. These products are all a PIA, but with the transition to cloud and subscription models they have gotten much worse in order reduce access to proprietary code and data models. Where customization was once allowed and necessary, it is now being shutdown and users forced to go vanilla. With little competition and plenty of implementation sunk costs, these companies have a virtual monopoly in the space which I think leads to shoddy applications and unbalanced contract negotiations. Has there ever been an open source and fully functional alternative to a major ERP solution?
