It's been four years since SAP first unveiled Business ByDesign (ByD), its software-as-a-service (SaaS) enterprise resource planning (ERP) application suite aimed at medium-size companies. Forrester believes that ByD now represents a viable SaaS offering worthy of consideration by business process pros. It has taken time for ByD to hit its stride after SAP rethought and then revamped the suite in response to user feedback. This report examines ByD, its likely future directions, and emerging use cases. The report also positions ByD within the rest of SAP's software stable and assesses its potential influence on that product portfolio, particularly now that SAP is actively building other apps on the ByD platform.
