Abstract
To verify the R&D portfolio management (R&DPM) proposed previously and to find a more practical version of the theory, a survey on 392 leading Japanese manufacturing companies was conducted. A model and hypotheses on R&D management were used to prepare the questions. Based on the answers from 126 companies, 263 examples of the R&D management processes in successful R&D programs were collected and subjected to factual and covariance analyses using the SAS software package for statistical analysis. Study showed that the processes can be represented by the PLS model, and verified the hypotheses satisfactorily. High correlations between theoretical evaluation of strategy and actual sales indicated that the R&DPM is an effective method of management.
