Final answer:
The combination of external and internal communication functions is called integrated communication. Congruence refers to the alignment between an individual's beliefs and their actions.
Step-by-step explanation:
The fusion of external and internal communications into a single function within organizations is known as integrated communication. This concept acknowledges that while we are connected now than ever before and can communicate in ways that are faster, easier, more powerful, and more widely accessible, the fundamental principles of communication remain unchanged. Both external and internal messaging are synchronized to ensure consistency, transparency, and efficiency in how an organization presents itself to all stakeholders.
Additionally, the answer to the query about the idea that people's perceptions of themselves should align with their actions is defined as congruence. When one's self-image and actions are congruent, there is a harmony between beliefs, values, and behaviours that is crucial for personal authenticity and well-being.
