To my knowledge, this is the only book about Enterprise Architect out there. Or do I miss something?

Today I released chapter 8 (out of 10) of my book "Teach Yourself Enterprise Architect in Ten Days" with a discussion of the most prominent new features of EA, released in version 11 (beta).

Updates stay free, but price increases after every new chapter.

I get this question a lot... so I've decided to write a book to fill that need:

an EA Expert called Thomas Kilian has written a whole book about this subject: (there's a free preview to download at the website too)

Hope this helps.

Wise words, Robert. The overall advice I would give is to be prepared to keep on learning and improving. You can only do that by regularly confronting other people with your work. The worst models are those made in an ivory tower. :-)

Good Luck with your undertaking! It's not easy but worth the effort.

For documentation, also take a look at the html export.

Day 3, Wednesday. Finally I got feedback from the Vinimble staff. They had some extra requests for me. Could I use Enterprise Architect to make them happy?

Read it in the new version:

New eBook available: Teach yourself Enterprise Architect in Ten Days.

Since I keep on getting requests for an Enterprise Architect crash course, I decided to write this book. Hope you enjoy it.


General Board / Re: Batch edit of elements?

Changing all elements to approved in one operation is certainly possible. It's one of my tips in the bonus chapter of the EA Tricks book.

Basically, you have to do this:

- right click package
- choose "package control" - "update package status"
- change to "approved"

I've created an EA board on pinterest:

Let me know if you are on pinterest and want to share EA images.

I often need to do that! For example, to guide an interactive workshop, it pays to print the page on A0 sized paper. Here's how I do that: copy the diagram to the clipboard with ctrl-b, then go to visio, paste it with ctrl-v and stretch it on the page. Then simply print it from Visio (or whatever diagramming tool you have that can work with the plotter).

Alternatively, you can compose a diagram of multiple EA diagrams, for example if you need to show different aspects of the model: the business process, the requirements, the information model...

General Board / Re: Agile - Use Cases, Scenarios and Stories
« on: December 23, 2010, 06:43:26 pm »
First and foremost: user stories are a "promise to talk". "Agile" means that you keep as little documentation as possible (but not less than that). On the other hand, "agile" does not mean you don't do analysis: instead, you only do analysis when it's needed for delivering the increment of the product. User stories are one way of accomplishing that.

In short the relationship between user stories and use cases (I'll publish more on my website soon): a user story can be part of a use case, but ideally, it describes one or more paths from precondition to postcondition. A user story is a way of partitioning the work intended for organising and planning, while a use case is an analysis technique in the first place.

In Enterprise Architect, I would do the following:
  • keep "use cases" as use cases, but avoid to analyse them in detail before needed in a sprint.
  • document "user stories"  (stereotype "requirements") and connect them to the right use case. Avoid to overanalyse them, just put the "as a <role> I want to <feature> so that I can <goal>" in the name.
  • Hook the user stories "requirements" to one of three "activity regions": TO DO, In Progress, Done. This can be your virtual taskboard.
This is more or less the same technique I also described in my book on Enterprise Architect. Works very well for me.
