This study aims to extend the product portfolio management (PPM) practices to cover all lifecycle phases and product portfolio layers by the means of comprehensively analysing the current PPM literature and the relevant practices of ten case companies. The principal results of this study include designing ontologies for the potential new business process hierarchy and for new PPM process concept over product lifecycle phases and portfolio layers. The new PPM concept proposal has been discussed and validated within a case company focus group to acknowledge the obtained comments. The results of this study can help cross-functional management teams in creating and implementing a process management approach for active PPM practices.
