Last May I went the the European EA User Group in the UK (Maidenhead) where the Enterprise Architect community gathered. Prior to run my presentation on the alternatives to set up a shared EA project, I attended several presentations, including the following ones that are covered in this article:

  1. Pragmatic agile model driven development using smart use cases by Sander Hoogendoorn (Capgemini, NL)
  2. EA Version 11 Cloud Services, OSLC and RAS by Phil Chudley (Dunstan Thomas, UK)

We are interested in just about everything you do with Enterprise Architect, from the organization of your model to enhancements you have made using MDG or the automation API, or even just a project with which you are especially happy. That said, we are not just after the sunshine stories and would be interested in hearing about any experiences learned the hard way. Do you have a story to tell? If so, please let us know.
Additionally we are looking for people who can lead a discussion / workshop on an Enterprise Architect related subject. Is this you? If so, please let us know.

To apply as a speaker, please see the call for speakers page or email Verena Hladik at verena.hladik[at]"

EA User Group London 2013 feedback

ea user group

I went to the first EAUG (Enterprise Architect User Group) on the 15th of May, where around 100 people from the EA community of users and experts gathered in London.

I summarised in this article a selection of talks I attended:

  1. "Modeling Software Intensive Systems" by Doug Rosenberg from ICONIX, hinting the concept of SwissML (SysML + UML) to reach the same amount of specifications for both software and hardware blocks of an embedded system. Doug discussed about the incompatibility of agile software development processes in a context where the delivered software is not the final product, but part of a system that encompasses software and hardware blocks, alongside safety and security risks associated with any possible bug.
  2. "SysML with EA" by Roman Bretz from Lieber Lieber GmbH who shared his experiences on clients projects where SysML modelling language and EA were used.
  3. "User Story : EA usage at EVRY" by Knut Paulsen from EVRY who explained how EA was used in his company, involving specific developments of EA Add'Ins such as a document generator and an Excel import/export tool, both tailored to comply with the adopted methodology.
  4. "User Story: How to do less work, have more fun and become (a bit) famous doing it" by Ian Mitchell from Ability Engineering, who shared his experience as a BA on large project at the European scale, leading to a number of advices and point of views to take into account!

EAUG London 2013 : a success

Coming back from my first EA user group, I've been very pleased with the experience. I'm already looking forward to next year's session!

On arrival, I collected my badge and marked down the sessions I was going to attend. Only "down side" was the spelling mistake on my badge, but after all "Guillaume" is tricky to write and even worse to pronounce when you're not French, never mind ;)

First of all, this was an opportunity to meet in person members of the EA community, which is a change from the on-line forums, community site, and other LinkedIN groups dedicated to EA. I also very much enjoyed as a UML/SysML/EA enthusiast participating to talks and debates that purely deal with Enterprise Architect tool and other modelling aspects. This is a change from previous IT events where yet interesting technical talks hardly impacted my daily tasks and concerns.

I heard some very interesting discussion over the impact of Agile techniques on software embedded in intensive systems via Doug Rosenberg's talk. Feedback from the other speakers on EA, SysML, and UML based on their past project experiences prompted some very useful ideas as well ("harvest the existing information into EA" as suggested by Ian Mitchell). I was also impressed with the extensive use of EA API by some companies.

I will shortly release articles to provide more detailed feedback from London 2013 EAUG.

The Enterprise Architect User Group will be hosting its second User Group Event on the 15th of May 2013.

The event is being held in Central London for a registration fee of £50.00 per person + Vat. The agenda for the day provides a number of sessions split accross the following event tracks:

  • Track 1 - Setting up projects for success with EA
  • Track 2 - Project Delivery with EA
  • Track 3 - Implementation & lessons learnt

This will be the first time that I'm going to an EAUG (Sparx version of the Java UG!), and I've already made my choice for the sessions to follow (SysML, BPMN2, user story, collaborative use...). I'm also keen on meeting other EA users, especially as I've had many exchanges via the Sparx forum with some of them for the last couple of years.
