The Solutions Continuum represents the implementations of the architectures at the corresponding levels of the Architecture Continuum. At each level, the Solutions Continuum is a population of the architecture with reference building blocks, either purchased products or built components, that represent a solution to the organization’s business need expressed at that level. A populated Solutions Continuum can be regarded as a systems inventory or re-use library, which can add significant value to the task of managing and implementing improvements to the IT environment.
