Enterprise Architecture Defined: Primitives and Composites

Written by John A. Zachman on Friday, 13 September 2019. Posted in Zachman International

To return to the basic point ... the kind of descriptive representations (models) you need for engineering are different from the descriptive representations (models) you need for manufacturing.

ZF Abstractions

For engineering purposes, you want to see one and only one thing in any one descriptive representation and you want to see the total set of occurrences of that one thing in the context of the entire object being described. You are trying to “normalize” the set of occurrences, get rid of any redundancies (except for “controlled redundancies”), make it as simple as possible ... LEAN.

In contrast, for manufacturing purposes, you want to see only one part (one implementation, one “piece”) of the object being described and you want to see (optimally) all of the “Abstraction” characteristics for that one part. You are trying to deliver a single implementation (part) defect-free as quickly and cheaply as possible.
