The choice of methodology for information system development (ISD) is a significant question faced by information systems (IS) professionals. A sizable body of research details the agile and traditional approaches independently. The choice of approach holds no universal agreement. A hybrid approach combines agile and traditional techniques, implementing multiple methods within one approach. The contextual analysis identified that the hybrid approach is attaining popularity. The investigation of factors ensure an informed, and justified approach can be selected. Prior research debates company culture, individual choice, and natural evolution as selection factors. Researchers have identified the need to find additional factors. This study proposes a design to identify the factors influencing the selection of hybrid. This research will be the first within the field to examine these factors in an Australian context. A matrix in progress aids the purposeful selection of the hybrid approach.
