Riccardo Martinelli is a PhD candidate in Sociology and Applied Social Research at Sapienza University of Rome and a Research Fellow at CNR–IRPPS, where he works on the ERC project Illicit Labour: Unveiling the Dark Sides of the Global Photovoltaic Industry. His research examines the end-of-life trajectories of photovoltaic modules across Europe and Ghana, focusing on the classifications, valuations, practices, and meanings through which panels are performed as reusable commodities, waste, or sources of secondary raw materials. Using a multi-sited, mixed-methods approach, he studies recycling, repair, reuse, informal recovery, and the transnational circulation of second-hand solar technologies. More broadly, his work explores how the boundaries between waste, commodity, and resource are produced and contested, and how green capitalism reorganises material flows and generates uneven social and environmental consequences across different geographical contexts.

So what is the software development procedure all about? It has to do with dividing the working process into various stages, as well as delegating various task among different employees. What is more, it presupposes taking some specific approach to organizing and optimizing the whole development process and managing the team work. That is why, there are various types of methodologies aimed at improving SDLC. So here are the top ones we are going to examine. the working process into various stages, as well as delegating various task among different employees. What is more, it presupposes taking some specific approach to organizing and optimizing

The main focus of this methodology is the project/product itself. That is why, it presupposes various constant alterations based on users and customers feedback, as well as internal changes related to the work of engineers. Agile software development methodology is free of rigid frameworks on the one hand. While, on the other hand, the working process is divided into short time boxes, thus offering the real results and feedbacks truly fast.

A new stage can only be started if the previous one is completed. In other words, each phase gradually flows into the next one. What is more, there is no going back to the previous stage. This approach is easy to understand as it presupposes a strict sequence of completed tasks. Waterfall methodology is often regarded as a classic representation her words, each phase graduof sopposite to the previous approach, oftware development.
