For Computers, instructions are software.

Functions of an Organized Process executed by the same Organization Actor at the same time.
A Manual Activity (example: checking a signature) is assigned to a Worker.

· When we use the word “Architecture” alone it means what allows or helps Sharing or Reuse: by
extension, also includes what is Shared or Reused.
· To avoid confusion, we prefer to use “Global Model” rather than Architecture to identify the
different Maps which help understand EA
Architecture is used with many different meanings:
· For “data Architecture”: see Data Model
· For “infrastructure Architecture” (Computer Configurations, Hardware Architecture, Middleware
Architecture, network Architecture, Platform Architecture, Portal Architecture, System
Architecture, Transactional Architecture, Web Architecture): see Actor Model
· For “integration Architecture”: see Transformation Model
· For “logical Architecture”: see Operation Model
· For Maps (such as Block Cartography): see Global Model
· For Reusable Component Architecture, SOA Architecture or Service Architecture: see Reused
Model
· For Organization Architecture: see Actor Model
· For software Architecture: see Operation Model and Transformation Model
· System Architecture: see Operation Architecture
· Approach and Tools: see Transformation Model
