Blending Product Thinking with Architecture

Product Thinking - understanding the use and need - is critical to not over engineering a product. In this session, we explore and use simple tools that help teams blend architecture with the need of the product. Too much design up front and you are bumping into the design all of the time (and losing time). Not enough design and your system can crumble in reality. How do you blend architecture so you have the right decisions at the right time, and give them enough due diligence? How do you embrace cloud and microservices and not risk getting into different failure scenarios or overly complicated maintenance and ripple effects? In this session we will walk through visualizations that help teams blend product thinking with architecture. Along the way, we will look at microservices and domain modeling as well as chaos engineering and fault tolerance - blending all of these into a context that is consumable by all and gives the right emphasis at the right time. Leave this session with simple visualizations and approaches that you can apply immediately to start blending product with architecture, especially if you are looking to run in a cloud world.

  26. 26. Try This Document Product Assumptions You Are Making Document Technical Assumptions You Are Making Think of 3 Ways You Might Be Wrong For Each Error, What Would Change? @joelTosi
  27. 27. What Are Your Constraints? Never been a perfect architecture Use Product Discussions to see what decisions when Grow context around the decisions - why / when What Can You Do About It? Necessary or Accidental? Assumed or Real? @joelTosi
  28. 28. Would New Constraints Help? Not All of the Databases No New Code Must Respond in Less Than 2 Seconds @joelTosi

  30. 30. Recap Be aware of models and dependencies Use Product Discussions to avoid language bias Use Journeys to find when decisions can be made Understand parts of the system need to be right / emerge @joelTosi
