A scenario-based requirement analysis of R&D projects from the cross-efficiency perspective

Research and development (R&D) project requirements have relationships with scenarios, scenario-based events and other factors, while traditional research does not always include quantitative analysis. Our research proposes a new method for prioritising scenario-based requirements within R&D projects based on scenario analysis and cross-efficiency. First, we decompose the scenarios and apply the design structure matrix to demonstrate the inside dependencies. Second, the multi-domain matrix (MDM) is used to establish a model for the dependencies between scenario-based requirements based on scenarios and scenario-based events and the complex network is used to measure the degree centrality between the scenario-based requirements. Third, the data envelopment analysis is utilised in the integrated cross-efficiency model, including self-efficiency and peer efficiency, to evaluate scenario-based requirements' economic benefits and resource utilisation. Finally, dependencies among scenario-based requirements for product R&D projects within company A are derived and ranked, indicating the model's validity.
