Foundation
Knowledge Architecture (KA) is the foundation, infrastructure, and common denominator of enterprise and business architecture, business process management, business rules, governance, resource management, adaptive case management, value chain, capability, motivation, as well as of most form of information management and modeling.

Collaboration
More so, collaboration, our greatest productivity tool, indispensable to enterprise and multi-organization businesses, exponentially increases the requirements for solid KA, as resources also need to be shared, with the implied conditions, responsibilities, privacy, and security, specific for each resource and for each collaborating party. Whether specific collaborators are systems, individuals, groups, departments, or organizations can affect scope but not principle.

Integration
In any case, everything that is known, shared, managed, and modeled is knowledge, as are all the rules and principles governing the collaboration, processes, and sharing. Understanding and mastering KA is key. It also explains why all these aspects and specialties (e.g. enterprise and business architecture, governance, business process, value chain, adaptive case management, capability, motivation, rule, and resource Management) are so interrelated and interdependent.
