Event Storming workshops from the other side

Home

Some time ago I gave the presentation about DDD and Event Storming during Girls Do IT 2019 conference. I also had occasion to run workshops on the same topic during Programistok 2018 and facilitated a few Event Storming sessions in the past (here is one example). So I can say that I have experience with this very nice modeling and business domain exploration technique proposed by Alberto Brandolini.

However, when I realized that I can take part in Event Storming Workshops organized by Krzysztof Owsiany and Mikołaj Jakubowski I didn't hesitate much to sign in. The workshops had two parts i.e. EventStorming - Big Picture and EventStorming - Design Level. I take part only in the second one while it was more interesting from my perspective.

In the beginning, we finished the Big Picture part and made a quick summary of what was done during the first part of the workshops. Then Krzysztof made an introduction to Design Level Event Storming. To do so he drew such a nice diagram:

Then we divided into 3 teams and started designing a part of a system in more details. Below you can find results of my team.

In the end, we compared designs prepared by all 3 teams. In was interesting to observe the difference between our designs even though we were supposed to design the same functionality.

To sum up I really didn't regret taking part in the workshops! For sure, it was not lost time. It was very valuable to see Event Storming session from the other side and observer how it is facilitated by someone else.

Are you ready to give a chance to Event Storming?

Girls Do IT 2019 - DDD and Event Storming

Home

English

At the end of March I will give a  presentation about DDD (Domain Driven Design) and Event Storming during Girls Do IT conference. Here is a short description:

DDD is a phenomenal approach to software development, which focuses on modeling and developing of a common language (a.k.a. ubiquitous language) used both by business and engineers.

Whereas Event Storming is a technique of modelling and gaining knowledge even of complex business domains, which is more and more popular especially among DDD practitioners. In 2018 it was even placed on the famous ThoughtWorks Technology Radar as the recommended modeling technique.

The aim of the presentation is to share experience and discuss the basics of Event Storming and DDD.

Pod koniec marca w czasie konferencji Girls Do IT przedstawię prezentację na temat DDD (Domain Driven Design) oraz Event Storming'u. Oto krótki opis:

DDD to fenomenalne podejścia do wytwarzania oprogramowania, które kładzie nacisk na modelowanie i wypracowanie wspólnego języka pomiędzy biznesem, a inżynierami.

Event Storming to natomiast technika modelowania i zdobywanie wiedzy nawet na temat bardzo złożonych domen biznesowych, która przebojem weszła na rynek IT, a szczególnie upodobali ją sobie właśnie praktycy DDD. Może wystarczyłoby powiedzieć, że w 2018 roku została umieszczona na słynnym Technology Radar firmy ThoughtWorks jako zalecana technika modelowania.

Celem prezentacji jest omówienie podstawowych zagadnień związanych z Event Storming'iem oraz DDD, a także podzielenie się ze słuchaczami praktycznymi doświadczeniami w tym obszarze.
