Scenario Frames for Presentation, Business, Data, and Services

  • Article

As part of our App Arch Guide 2.0 project, we're creating scenario frames to organize customer problems into meaningful lists.   These particular frames are an elaboration of our App Arch Meta Model.  This helps scope our guidance.   We also use them to test effectiveness.  The value of the guidance is the value of the problems solved.
