White papers provide in-depth technical discussion and best practice guidance on a wide range of modeling topics. The information presented by industry experts from the user community will help you learn new approaches to modeling and solving real-world problems using Enterprise Architect.
Background An enterprise architecture reduces the cost of operations, through reuse of standard pieces of technology, application and data, and network . However siloes of information in specialist corporate IT teams are not making it through to a central knowledge base, meaning that function and data are repeated in a string of parallel universes, that are not congruent, and have synergies that remain largely unexplored. Enterprise architectures are often seen as not addressing the coalface reality of reuse and accessibility of data and services. An Enterprise Information Model can address the gap between business and technology owners, practicality and principle,…

The Unified Profile for DoDAF/MODAF (UPDM) is a modeling standard by The OMG that supports two popular defense frameworks. This whitepaper covers the core concepts behind modeling with UPDM using Enterprise Architect. When organizations work together on a strategic task, all interacting entities – from human resources to deployed systems – must be well coordinated to achieve the desired outcome. Strategic interactions can range from joint military operations, to cooperation between fire search and rescue task forces. UPDM provides an appropriate modeling framework for describing such interactions. This whitepaper explains how to model with UPDM using Enterprise Architect's MDG technology…

Increasing Business Agility using the "Goal-Driven SOA" Process
Written by Birol
This animated version of the Goal-Driven Service Oriented Architecture (Goal-Driven SOA) process illustrates on a short case study how companies can capitalize on their business capabilities (*) in order to react swiftly and coherently to changes. Thanks to its reusable goal-driven business capability components - easily adaptable to changing requirements, the "Goal-Driven SOA" process aims at allowing companies to control execution of their processes and underlying SOA services then adapt them efficiently to targeted situations. In order to show how to align IT systems to changing decisions, this presentation illustrates a bridge from Business Goals to IT system components using…

This animated short case study of 18 diagram slides presentation illustrates how simple UML and SysML diagrams can be successfully used there to enhance requirement traceability till software architecture layers in order to better dealing with requirement changes using agile methods. Since a few years, companies try to customize the usage of Agile Methods ( Scrum, XP,...) in order to be able to deliver their products on time and on budget. One of the serious obstacles they meet using such methods is about informal and untraceable requirement gathering that causes extra costs along iterative development lifecycle. Gathering requirements on the…

It’s often the case that we need to map various attributes on entities into other entities. For example you might need to migrate data from one system to another and structurally the same concepts are held slightly differently. Documenting these mappings is not obvious in the UML, so below I’ve provided a simple example of how a composite structure diagram could be used to provide the mappings. Some notes have been added where conversions need to be performed and these could be represented more formally using diagram references to behavioural diagrams such as sequence or activity diagrams. This is quite…

Overview It is not an easy step to go from reading about UML and UML tools to handling a real project documentation. In reality project documentation consists of documents in different formats: text, diagrams, presentations and lately even media files. We need a way to bind them all together. Enterprise Architect offers a solution with its common elements: Boundary, Text and Hyperlink. They are not talked much about but they are the key to the complete documentation set. Sample Project For illustration, I have created the Sample project. Its structure follows well defined project phases. Here they are, both in…

Enacting the Service-Oriented Modeling Framework (SOMF) using Enterprise Architect
Written by FrankTruyen
This document presents an overview of the modeling notation introduced by Michael Bell in his seminal book Service-Oriented Modeling - Service Analysis, Design and Architecture. SOMF provides a formal method of defining services at different levels of abstraction, along with a set of disciplines to guide practicing modelers. The overview focuses on the modeling facets, including meta-model concepts and notation, using sample diagrams for illustration.

eBook: Embedded Systems Development using SysML
Written by doug rosenberg
Embedded Systems Development using SysML is not just an overview of the SysML modeling notation - it is a practical guide for systems engineers! The book provides a well defined approach to systems development, and applies it to a detailed example Audio Player system. In this e-book, author Doug Rosenberg introduces a new roadmap for embedded systems development – ICONIX Process for Embedded Systems. Each step of the process roadmap is clearly explained, and illustrated by example, using Sam Mancarella's Audio Player model constructed in the Systems Engineering edition of Enterprise Architect. Topics covered in the e-book include SysML modeling…

Describes experiences and lessons-learned from the Large Synoptic Survey Telescope (LSST) project. The sheer size and complex nature of LSST, bring a unique set of challenges and a massive software modeling endeavor. UML and ICONIX process are critically important in such an undertaking. Includes an in-depth discussion of tailoring ICONIX Process to support algorithmically-intensive development. In its first month of operation, the LSST will see more of the Universe than all previous telescopescombined. Its rapid‐fire, 3 billion pixel digital camera will open a movie‐like window on objects thatchange or move; its superb images will enable mapping the cosmos in 3D…

ICONIX Process for Service-Oriented Architecture - A roadmap for SOA development w/ web services
Written by doug rosenberg
Doug Rosenberg, ICONIX Figure 1 - A “Secret Decoder Ring” may be required for Service Oriented Acronyms Trying to make sense out of the “acronym-scrabble” that engulfs Service Oriented Architectures (SOA) is a major challenge. We’re going to take a shot at it in this article by defining a process roadmap and following a single example all the way from architecture to code. Along the way we’ll illustrate many of the key features of Enterprise Architect Business and Software Engineering Edition. The example we’ll follow will be a Service-Oriented Architecture (SOA) car rental system model, developed by…

ICONIX Process for Embedded Systems - A roadmap for embedded system development using SysML
Written by doug rosenberg
Doug Rosenberg, ICONIX At ICONIX, we’ve had pretty good success when we defined an unambiguous development process, and presented that development process in “roadmap” form. We’ve developed process roadmapsfor use case driven software development, business modeling, design-driven testing, and algorithm-intensive software design. In this article we’re going to do it again, this time using SysML to describe embedded systems that involve a combination of hardware and software. Figure 1 – ICONIX Process Roadmap for Embedded Systems Development Figure 1 shows the top level roadmap for ICONIX Process for Embedded Systems. As you can see, our roadmap starts off by defining…
