Description

There are plenty of other courses that explain what is Enterprise Architecture. This one is different - because the course tutor is someone who has been at the leading edge of Enterprise Architecture since 1984, so he really knows his stuff and knows how to explain it simply and clearly.

This course will:

  • Give you a clear and simple explanation of what enterprise architecture is
  • It is aimed at anyone studying to become an enterprise architect, anyone planning to use enterprise architecture, and anyone who is just plain curious to know what enterprise architecture is all about
  • The course is not too long, and not too short; and it's well structured so it's easy to dip into and come back to if you need more information


Who is the target audience?
  • This course is for students who want a simple and straightforward introduction to Enterprise Architecture.
  • You will benefit from this course if you want to become an Enterprise Architect, or you are training as an architect.
  • The course will be useful to you if you are working in an enterprise using Enterprise Architecture, and you want a better understanding of what this means.
  • You will also find the course useful if you need to explain Enterprise Architecture to colleagues or clients.

Welcome to the course! In this video I give a very brief introduction to the course.

This lecture gives you a brief outline of the course, its layout, and the questions that it will answer.

You might find it useful to watch my 6-minute introduction to Enterprise Architecture on YouTube, or to see some of the other sort introduction videos that are available on YouTube (in a YouTube Playlist). There are links to both of these in the Resources.

What is an Enterprise?
6 Lectures 12:35

This lecture explains that "enterprise" can mean any human endeavour or undertaking.

An enterprise can therefore be:

  • Equivalent to an entire organization
  • Part of an organization
  • A project
  • A creative endeavour
Preview 01:58

In this lecture I'll describe the three key things that exist for any enterprise:

  1. A group of People
  2. With a Purpose
  3. Supported by a Platform
Preview 02:33

No enterprise exists in isolation. Enterprises collaborate with other enterprises. And all enterprises operate within a particular environmental and social context.

This lecture explains what that means for Enterprise Architecture.

Preview 02:06

In this lecture I'll describe the components that can be found in almost every enterprise. 

Preview 02:53

In this lecture I explain how:

  • The architecture of an enterprise is created from the set of components that are necessary to form an enterprise.
  • All of these pieces are structured and arranged in ways that allow the enterprise to exist and its aims.
  • The structure and arrangement of all these pieces is the architecture of the enterprise.
Components make up an enterprise architecture
01:03

Finally in this section I explain how every enterprise has an enterprise architecture.

You might find a post I wrote on LinkedIn interesting: Enterprise Architecture Isn't Optional - there's a link in the resources.

How do you "architect" an enterprise?
10 Lectures 25:29

In this lecture you will learn why it is important to see Enterprise Architecture as four things:

  1. The actual architecture of an enterprise
  2. The process of architecting
  3. discipline
  4. And a description of the enterprise architecture
Enterprise Architecture - Process, Discipline, and Description
00:46

In this lecture you will learn about the key ingredients of enterprise architectures.

Remember - every enterprise has an architecture!

You will learn about Paradigms, Patterns, and Principles; Components or Building Blocks; and Architecture Domains.

I will also briefly explain the concept of a metamodel.

A reminder - what is the actual architecture of an enterprise
04:49

In this lecture you will learn about the main benefit and value from architecting an enterprise. This lecture you will introduce the idea of architectural thinking, and demonstrate how this provides us with several different levels of architectural understanding.

You will also learn the important distinction between architectural thinking and systems thinking.

In the resources you will find a link to a post I wrote on LinkedIn about the Levels of Architectural Understanding - which also includes some interesting comments and discussion.

This lecture will provide you with a clear and simple outline of what enterprise architects do.

An outline of the process of architecting an enterprise
02:08

This lecture will explain how architects balance the need to manage an enterprise architecture with other forces that are beyond their direct control.

I will introduce and explain the concepts of Architectural States, Enterprise Patterns, Strategic Vectors, Roadmaps, and Emergence.

Changing the Enterprise Architecture - managing its evolution
03:51

This lecture will provide you with a simple overview of the skills and experience that enterprise architects need.

An outline of the discipline of enterprise architecture
02:14

In this lecture you will gain an overview of some of the key techniques used by enterprise architects.

A brief overview of enterprise architecture techniques
01:58

This lecture will provide you an understanding of how enterprise architects describe an enterprise architecture. In particular it will explain how architects describe building blocks, patterns, constraints, enablers, and options.

An outline of enterprise architecture descriptions
02:44

In this lecture you will learn why architecture frameworks are so important in Enterprise Architecture. 

You will find out why there are several different architecture frameworks, and why this causes some confusion! 

Finally you will gain a good understanding of how architecture frameworks are used by leading architects and architecture teams.

There are two useful links in the resources:

  • A link to the ISO 42010 web site, which gives a list and description of the most common enterprise architecture frameworks. ISO 42010 is the web site for the International Standards Organization standard for Architecture Description - which includes a formal definition of an architecture framework
  • A link to a discussion of the difference between a framework and an ontology - both of which are vital techniques in enterprise architecture. This is a post that I wrote for LinkedIn.
Architecture frameworks
03:35

So, architecting an enterprise is a process. It requires experienced and skilled enterprise architects, applying a professional discipline called “Enterprise Architecture”. And it produces descriptions of the architecture of an enterprise (in its current and future states) that guide changes to the architecture.

In the downloadable resources you will find a PDF extract from my book, "Enterprise Architecture - the eight fundamental factors", which gives you a complete overview of the eight factors that are mentioned in this course.

Conclusion
3 Lectures 04:26

There are several things that make Enterprise Architecture distinctive, but in this lecture I focus on the two most important characteristics that make it a unique and special discipline.

This lecture asks a key question: do we need Enterprise Architects? 

Now that you've completed this course - what do you think? Do you agree with me or not? Do you think that enterprise architecture is needed or not?

Do we need Enterprise Architects?

Here is a brief exercise that you can do. It will help you think about the ideas we have covered in this section, and help you put them into your own words.
