Progress monitoring and assessment of objectives are a challenging task for large, complex research, technology development and innovation (RTDI) projects comprising dozens of partners and different technical domains. It is difficult for project management, project partners and funding authorities to keep an overview whether defined high-level goals are adequately covered in the project innovations. This paper presents DEWI-Frame, a novel consistent mathematical-logical assessment and monitoring framework that has been developed in the course of the ARTEMIS Joint Undertaking project Dependable Embedded Wireless Infrastructure (DEWI). The main innovation in the proposed assessment framework is focused on the two-dimensional assessment of i) technological progress aligned with Technology Readiness Levels (TRLs), ii) the project objectives assessment and iii) the consolidation of these assessment results. The methodology applied within DEWI-Frame can be tailored to be used in a variety of RTDI projects with an easy parameterisation of scaling factors. DEWI-Frame is equally applicable for technology and products as well as methods as targeted results in RTDI projects.
