Development Complexity Circle

This is how Sven views software development in general.
Each box communicates only with the two surrounding boxes.

  • User experience include business processes and general satisfaction with the software.
  • UI is the interface between the software and the user.
  • UX-model is an abstraction of the problem to be solved.
  • App is the software logic.
  • App-model is the data model needed to support the app functionality.
  • API defines the communication with backend.
  • Platform is the functionality and data model of the backend. It should resemble the app-model, but is not required to be identical.
  • Analytics is more or less complex aggregations, data science and AI.
  • Storage is backend storage. It may be on premise or in the cloud.
  • Ingest is data engineering for importing data.
  • Sensors are similar to UI, but communicates only with backend.
  • Proof of concepts generally end up in dashboards, which are in no way optimized for actual problems.
  • Cocreation generally deifines the ux model, but is not really integrated with actual usage.
  • Prototyping with a simulated backend is an agile way to fit a full-stack solution to the problem and to define consistent UI and API.
  • Sales generally focus on the platform and whatever user experience that is defined by the platform abstractions.
  • The evaluation of a project is generally focused on the actual experience of the users, which may differ a lot from the platform, since it is more complex.
