Final answer:
Cassidy's group appears to be in the 'Performing' stage of group development, characterized by strong cohesion, morale, and progress towards goals. The frame alignment process can be seen in historical examples like the civil rights movement, where different organizations united to form a stronger collective.
Step-by-step explanation:
The question refers to the various stages of group development. Based on the description provided—that Cassidy's group is highly cohesive and has high morale, it is progressing towards achieving its group goals—the group seems to be in the 'Performing' stage of Tuckman's stages of group development. This stage is characterized by high levels of organization, competency, and collaboration, and is usually the most productive phase in a group's development process.
As for frame alignment process, there are several historical examples where organizations with similar goals banded together to create a stronger social movement. One notable instance would be the collaboration between different civil rights groups during the civil rights movement in the United States. Organizations like the NAACP, SCLC, SNCC, and CORE each had their own methodologies and areas of focus, but they came together at various points during the movement to amplify their collective voice and impact.
