In other terms, design is an intentional act that aims at modifying future reality. One of the main problems of this complex process is the gap that is spontaneously created once the product, from being ideal and belonging to the design space, becomes tangible encountering the real environment (which could be of production, distribution, use, maintenance, etc.). Products are in fact anything but static, predictable or under control. They are dynamic entities, that break down, age, and are – sometimes – being personalized and modified. These vari- ated modifications occurring in products (in time, often because of use dynamics) have been here defined as change. Changes occurring in products ultimately change also the perception we have of them, leading to either disruptive or beneficial scenar- ios. If disruptive changes are not contained and beneficial ones are not supported, they might provoke early products’ abandonment, with negative implications (for example, in terms of sustainability). In fact, even valuable design outcomes face re- jection: on the one hand top-down standard solutions – created for all – might not reach the goodness of fit that is required, while on the other hand bottom-up local solutions – created for one – are hard to be adapted, because of their very contextual nature. In both cases problem can be recognized on that these design outcomes are generally not designed with a “real use” perspective (that occurs in time) and, in case they are, it is often under the belief that only expected things will happen. To bridge this gap between design space and real environment a constant engage- ment and interaction between products and different stakeholders is adovocated. Summary / Samenvatting 9 This process has been here defined as conversation, to underline as this mutual ex- change of information can be seen as a learning process. Most importantly active engagements that occur in the design-after-design space are aimed at. In other words, the design outcome changes thanks to the contact with (non-)human actors of the products’ ecology. This is what has been defined as re-appropriation. In fact, every actor provokes change and eventually learns what conserves and what evolves in the designed outcome. In return, this experience can change the perception that the ac- tors have of the design object. This mutual change, a real conversation, can be seen as second-order cybernetics. It occurs in time and is rarely considered during the design process, being hardly predictable. Open-ended Design is here proposed as possible approach to facilitate the conditions for this conversation to happen, and has been defined as a design outcome that is able to change, according to the changing context.
