Does culture impact software design? @ DDD Europe 2022

Does culture impact software design? @ DDD Europe 2022

DDD is about understanding and communicating complexity. We have long recognized that the most effective way to communicate complexity is via human language. But language poses a challenge when working in a team comprised of members of different (sub)cultures and nationalities, each with a native language that might not be the same as the language we are communicating in. Each of these cultures has a different perception about how to communicate effectively. By way of example, in some cultures, it is considered appropriate and respectable to use the tentative voice “perhaps we should consider trying X”. Whereas in other cultures it is the assertive voice that is valued “This is how we should do it”.

Assuming that everybody in the room wants to communicate effectively, what aspects can we define that impact our design? What organizational culture fits better with what type of architecture (microservices, monolith)? And what cultural needs must these architectures and boundaries address to succeed? Join us in this hands-on where we together explore these challenges!

    during collaborative modeling or refinements or design sessions are effective. Conversational constraints theory Clarity: Do people understand what I am saying Feelings of others: Am I hurting people, or being rude? Own image: Do people see me the way I like them to see me.

  5. Organizational culture is the pattern of basic assumptions that a

    given group has invented, discovered, or developed in learning to cope with its problems of external adaptation and internal integration, and that have worked well enough to be considered valid, and, therefore, to be taught to new members as the correct way to perceive, think, and feel in relation to those problems. - Edgar Schein Business stakeholder Domain Experts Architects managers analyst ...... Code Engineering Team DDD implies bi-​directional flow. Can we do DDD in every culture?

  7. Artifacts: These are the “visible” symbols of the culture. It

    can include anything from clothing styles to posters on the wall to the volume of speech. Even if not understood, the artifacts that last are typically deeply tied to the underlying culture. Values: These are the “espoused” values – often found on company websites and also the area which has the greatest chance of being disconnected from reality. Basic Assumptions: These are the beliefs that people use to make day-​ to-​ day decisions within an organization. For example, an assumption may be that “it is best to speak up when I have a good idea.” Judging the assumptions and trade-​ offs people make on a day-​ to-​ day basis is often the quickest way to understand the “real” culture. think-boundless.com Edgar Schein - Organizational Culture: Artifacts, Values & Assumptions Exploring Edgar Schein's ideas on culture including the artifacts, values & assumptions framework and his model of anxiety for "learning organizations" https://think-​ boundless.com/edgar-​ scheins-​ anxiety-​ assumptions-​ powerful-​ ideas-​ on-​ culture/
