Tra probabilismo e possibilismo: un confronto sul cambiamento

This contribution aims to reflect on evaluative thinking based on the theoretical and practical contributions of Albert Hirschman and Judith Tendler. The focus is primarily on change, exploring the innovative as-pects of this evaluative approach, which centers on the implementation process. The authors suggest that the implementation process is a long journey of discovery across various fields, encountering stages that do not follow a predetermined linear pattern but grapple with unpredictable complexity and uncertainty. In situations of uncertainty, evaluation can seize the opportunity to promote change, addressing complexity with-out simplifying it, as often occurs in mainstream approaches
