Scenario and Feature Frame

A Scenario and Feature Frame is a quick way to show your project’s incremental value and dependencies.  It’s helpful for showing your management what you’ll deliver in terms of a baseline release.  It’s helpful for you in terms of finding ways to reduce dependencies.  If you have a bunch of scenarios that depend on certain features, then you don’t have cuttable scope.  The key is to find ways to factor your scope into incremental value.

patterns & practices Solution Engineering

This is one of my favorite figures that shows how we do solution engineering in patterns & practices at Microsoft:
Architectural Scenarios
It all starts with a scenario.  It has to be a meaningful problem.  You can’t evaluate an architecture in a vacuum.  In order for us to build useful baseline architectures, we need to pick the right scenarios that flex the right engineering decisions.
Patterns are simply problem and solution pairs.  In our case, we tend to focus on application, architecture or solution level patterns.
Baseline Architectures
Baseline architectures are skeletal applications.  They’re just …
