A building blocks approach starts with the universe of possible solutions and determines the common fundamental elements that constitute such solutions. It then goes about standardizing these fundamental elements and commoditizing them. This enables an ecosystem of actors who have the agency to ‘build-on’ using these building blocks to deploy solutions across varied contexts. In the Decision Management world a building blocks approach started to dominate the ecosystem to build context-specific decision models (which preserve individual context) while leveraging standardized Decision Microservices (building blocks).
