Exam OG0-091 topic 1 question 156 discussion

A good building block has the following characteristics: - It considers implementation and usage, and evolves to exploit technology and standards - It may be assembled from other building blocks. - It may be a subassembly of other building blocks. - Ideally a building block is re-usable and replaceable, and well specified. A building block's boundary and specification should be loosely coupled to its implementation; i.e., it should be possible to realize a building block in several different ways without impacting the boundary or specification of the building block. - A building block is a package of functionality defined to meet the business needs across an organization - A building block has a type that corresponds to the enterprise's content metamodel (such as actor, business service, application, or data entity) - A building block has a defined boundary and is generally recognizable as "a thing" by domain experts - A building block may interoperate with other, inter-dependent building blocks.
