SAP (Systems Applications and Products in Data Processing) is a large suite of software products best described as being an Enterprise Resource Planning (ERP) system. Many large scale companies use SAP to cover a variety of processes related to accounting, finance and commerce, as well as a variety of other functions. While a tester may not be working directly with it, it's a very good bet that if you visit sites that are large enough, you are absolutely interacting with a SAP system(s) somewhere. For this episode, Matthew Heusser and Michael Larsen welcome Simon Evans to talk about all things SAP, the ways in which it shows up in so many places, and ways that testers can level up and come to grips with this large ecosystem of inter-related systems.
