How cognitive biases and ranking can foster an ineffective architecture and design @ DADD 2021

The power of collaborative modelling comes from having a diverse group of people who, together, have a lot of wisdom and knowledge. You would expect that all this knowledge will be put to use, co-creating, and to design a model. In reality, we don’t actually listen to all the available input and perspectives due to cognitive biases and ranking. Because not everything that needs to be said has been said, we will end up with sub-optimal models and architecture. Even worse, people don’t feel part of the solution and don’t commit to it. Good architecture and design need all the insights and perception. If you are not aware, cognitive biases and ranking kills those insights and kills the effectiveness of your architecture! We will let you leave this talk with how being aware of cognitive bias and how Deep Democracy the lewis method can really let the group say what needs to be said and take a collective autocratic decision in architecture and designing your software.

6. @EelynvanKelle @kenny_baas @EvelynvanKelle @kenny_baas We’re dealing with complex adaptive socio-technical systems. Those 3 aspects impact each other. Balance is key
7. @EelynvanKelle @kenny_baas @EvelynvanKelle @kenny_baas Open office space to improve communication
8. @EelynvanKelle @kenny_baas @EvelynvanKelle @kenny_baas If you design a monolith or part of a software landscape without boundaries or the wrong boundaries, you just architected an open office space for software teams.

11. @EvelynvanKelle @kenny_baas “Architectural design is system design. System design is contextual design — it is inherently about boundaries (what’s in, and what’s out, what spans, what moves between), and about tradeoffs.” —Ruth Malan

14. @EvelynvanKelle @kenny_baas “If the architecture of the system and the architecture of the organization are at odds, the architecture of the organization wins” —Ruth Malan
15. @EelynvanKelle @kenny_baas @EvelynvanKelle @kenny_baas Creating a shared sense of reality
16. @EelynvanKelle @kenny_baas @EvelynvanKelle @kenny_baas Visual and Collaborative modelling is a practice of using requirement analysis and modelling techniques to create a shared understanding.

44. @EvelynvanKelle @kenny_baas Discussion Dialogue Actions, thinking fast Insights, thinking slow Convince, take a stand Understanding, listen Think against other (yes, but..) Think together with others (Yes, and…) Answer are central The questions are central Attack and defence Investigate and check Opinions and arguments Principles, values and norms Judgement postpone judgment Finding solutions find the underlying reason Risk: false consensus, powerplay Risk: responsible abstraction, woolly

52. @EvelynvanKelle @kenny_baas 1. Idea: You have an idea, but nothing is certain 2. Suggestion: You have a clear intention, but other insights are more than welcome 3. Proposal: You have a concretely worked out proposal. Only serious objections can influence the decision 4. Command: Decision is made, what does it take for you to go along? How much space do you give?
