Enterprise Architect Best Practices

Agenda

When you can do anything…

Examples

Protecting yourself… from yourself

When you can do anything…

• Pick an organizing paradigm

– e.g. TOGAF

• In this example, a package for each phase

• Phase A – mind maps, reference models

• Phase B – use case, business activity, business architecture

• Phase C – application architecture, sequence diagrams, CIM data model

• Phase D – Technology architecture

Phase A

• Reference Models

• Mind Maps

Phase B• Use Cases

– Actors – separate package

• Business Activity diagrams

• ArchiMate Business Architecture

Phase B – Activity Diagram

• Use your Actor references!

Phase B – Activity

• Swimlanes

– have Actors from the list

– Local names as well

• Other tips

– Control flow for activities in the same lane

– Object flow when crossing lanes

Application / Data Architecture

• CIM!

• But not just CIM – linking CIM to architecture

application Phase C

MR-MS OMS

PROTECTING YOURSELF… FROM YOURSELF

Version control

• Enterprise Architect is Version Control Compliant (VCC)

– Subversion (https://subversion.apache.org/)

– SlikSvn (https://sliksvn.com/download/)

– TortoiseSVN (https://tortoisesvn.net/)

• Make a local repository

– Windows Explorer, create a folder, right-click -

EA VCC Integration

• Select Package

• From the menu:

– Project

– Version Control

– Version Control Settings

BASELINES

Baselines

• Corporate edition

– Allows you to take a “snapshot” of your model

– Package Baselines…

– Give it a version number

• Compare baselines

• Compare baselines to a file

• Import/Export files
