Core ideology provides the bonding glue that holds an organization together as it grows, decentralizes, diversifies, expands globally, and attains diversity within. Think of core ideology as analogous to the principles of Judaism that held the Jewish people together for centuries without a homeland, even as they spread in the Diaspora. Or think of it like the truths held to be “self-evident” in the United States Declaration of Independence, or the enduring ideals and principles of the scientific community that bond scientists from every nationality together with the common purpose of advancing human knowledge.
Any effective vision must embody the core ideology of the organization, which in turn consists of two distinct sub-components: core values and core purpose.
