What is a foundational principle of family development according to the text?

The idea that families should have a coordinated support system is a foundational principle of family development because it emphasizes the importance of collaboration and integration among various resources and services. A coordinated support system ensures that families can access the care, education, and assistance they need in a unified manner, which helps to create stability and promotes overall well-being. This principle acknowledges that families often face complex challenges that require the input and support of multiple entities, including community organizations, healthcare providers, and educational institutions.

In contrast, while financial support, access to varied resources, and authority structures can be components of family functioning, they do not encapsulate the holistic view necessary for effective family development. Simply having financial support or access to various resources does not guarantee that a family can navigate life's challenges efficiently without coordination. Likewise, submission to authority does not foster the necessary relationships and collaboration that are critical for families to thrive and develop healthily.
