Cviegas Cis512 Week 2 Enterprise Architecture Zachmans Model
1. Step 2: Make a video less than 7 minutes with you talking directly, answering the following question:
What is Zachman's Framework? Hint: Talk about the SCOPE, BUSINESS MODEL, SYSTEM MODEL,
TECHNOLOGY MODEL, DETAILED REPRESENTATIONS & FUNCTIONING ENTERPRISE.
Tips: Use the webcam/camera in good lighting (light source behind camera or on top, dark
background), write what you plan to say, print it in big font, paste it on the camera, so you are directly
looking at the camera, be a bit loud and clear . Practice, practice, you will get it. See Week 2
Supplements section for more tips.
Step 3: Upload the video on http://www.youtube.com/ - You can sign-up for a free account.
Samples have been posted on the Announcements section.
1) Zachman Framework : A framework for enterprise architecture that provides both a
formal and structured way of viewing and defining an enterprise.
2) The framework is used for organizing enterprise architectural “artifacts” in a way that
considers:
a. Who does the artifact targets (business or owner)
b. What issue is being addressed: Data or functionality
3) Artifacts include: Design documents, specs and models
4) The framework is a Matrix and names after its creator John Zachman who first developed
the concept in the 80s while employed at IBM and which has been updated several times
since its development.
5) Zachman’s Framework:
a. SCOPE: Contextual and for the planner: is the first row of the model which is
the size, shape, partial relationships, and purpose of the final structure and it
corresponds to an executive summary for a planner or investor who wants an
overview of estimate of the scope of the system, what it would cost, and how it
would relate to the general environment in which it will operate.
b. BUSINESS MODEL – conceptual and for the Owner - the architect's drawings that
depict the final building from the perspective of the owner, who will have to live
with it in the daily routines of business. They correspond to the enterprise
(business) models, which constitute the designs of the business and show the
business entities and processes and how they relate.
c. SYSTEM MODEL – Logical and for the designer - architect's plans are the translation
of the drawings into detail requirements representations from the designer's
perspective. They correspond to the system model designed by a systems analyst
who must determine the data elements, logical process flows, and functions that
represent business entities and processes.
d. TECHNOLOGY MODEL – Physical and for the builder - contractor must redraw the
architect's plans to represent the builder's perspective, with sufficient detail to
understand the constraints of tools, technology, and materials
e. DETAILED REPRESENTATIONS – Out of context and for the Subcontractor -
Subcontractors work from shop plans that specify the details of parts or
subsections. These correspond to the detailed specifications that are given to
programmers who code individual modules without being concerned with the
overall context or structure of the system
2. f. FUNCTIONING ENTERPRISE – Real and for the users.
6) Focus or Colums:
a. The data description — What
b. The function description — How
c. The Network description — Where
d. The people description — Who
e. The time description — When
f. The motivation description — Why
