Which one of the following reference building blocks is not part of the Solutions Continuum?

The Solutions Continuum consists of various reference building blocks that represent different types of solutions and their relationships. Understanding the context of these building blocks is key to recognizing their roles within the Solutions Continuum.

Foundation solutions are core components that serve as a base for developing organizational architectures. These are critical as they represent the fundamental elements necessary for establishing more complex solutions.

Common systems solutions are generic systems that can be used by multiple organizations or industries and embody best practices that can be reused. They provide a shared resource that organizations can adapt and deploy.

Organization-specific solutions are tailored to meet the unique needs and requirements of a specific organization. They take into account the distinct characteristics and goals of that organization, allowing for customization that can enhance operational effectiveness.

In contrast, systems libraries do not fall under the category of the Solutions Continuum. Instead, they refer to collections of data, tools, or resources that may be utilized during the architecture development process but do not specifically serve as a reference building block within the context of the Solutions Continuum. Thus, recognizing systems libraries as separate from the conceptual framework of the Solutions Continuum clarifies why this is the correct choice.
