Decision-makers in the public policy and business arenas need tools to deal with multiple sources of complexity in Circular Economy (CE) transitions. System Dynamics (SD) facilitates coping with increased complexity by enabling closed-loop thinking via identifying the causal structures underlying behaviour and permitting to proactively experiment w...
Article
The electrical and electronic equipment (EEE) industry requires a Circular Economy (CE) transition, and decision-makers need support to deal with the complexities of such change. The goal of this research is: (1) providing an SD-based conceptual model for CE systems that clarifies their potential for decelerated flow of resources; (2) providing a s...
Article
The medical device industry leads to high environmental footprint while holding fundamental social function. The panorama is composed of devices with rather specific lifecycles and impacts: imaging equipment that eventually become electronic waste, sophisticated invasive devices that require sterilisation before reprocessing, and potentially infect...

It is a consensus that we are passing by a period of severe natural resource depletion. Our current linear socioeconomic system, characterized by the product discard at the end of product life, is one of the main causes of this natural depletion. Some governs and institution, as European Union [3] and The Ellen MacArthur Foundation [1], are calling...
Article
In the last decades, companies have shifted from traditional business models based on selling products to product-service systems (PSS). Despite this tendency, there is a paucity of complete methodologies and tools to guide companies on how the transition should occur. To address this issue, the goal of this research is to present a complete framew...

Companies that follow a reference process are usually more successful. Over the last decades many different reference process models have been developed primarily in academia. Nevertheless, many approaches have not been adopted in practice. The paper analyses the most known reference models according to discipline, knowledge area, considered design...
Article
One of the ways to improve the New Product Development (NPD) process is to eliminate the problems that arise over years of practice. This article describes the systematization of recurrent NPD management problems. The main NPD problems were found to be recurrent; hence, the systematization resulting from this study allows for the identification of...
Article
This paper presents a compilation and empirical survey-based evaluation of the metrics most commonly used by program managers during product development management. This work is part of a bigger project of Massachusetts Institute of Technology (MIT), Project Management Institute (PMI) and International Council on Systems Engineering (INCOSE). Three...

The proposed method is based on the CRT method and incorporates best practices of project management and activities to identify relevant opportunities for improvement. Templates are...
Article
New product development (NPD) processes can be improved through change projects managed in a context of business process management (BPM). In order to fully characterize and implement NPD process change projects it is necessary to be able to identify and adequately describe “to-be” processes. These “to-be” processes should be based on best practice...
