Project Spring is a multi-year Sabre initiative to modernize corporate systems by investing in technology that supports business growth, moving away from fragmented systems, and streamlining processes. Key programs under Project Spring include implementing SAP S/4 HANA, integrating customer projects to contracts using PPM, and a new mobile tool for time entry and expense management called OneSabre Time. The document then describes Sabre's "Lead to Cash" process for work orders and change requests, and how Project Spring aims to automate more of this process over time.
