9 Strong and Weak Points Strong Points  Coherent and well defined division of the activities;  Software Architect experience in Games Domain  Reuse of OXE’s templates[1];  Reuse of information from other teams; Weak Points  How to build a general architecture for SPL?;  The [2] specify “examples” or “how to do” a few turns.

10 Learned Lessons Was not easy to guide the architecture developer by the article[2].  Module Composition? What is the module granularity?  Choose Patterns What are the patterns that must can be used? Gamma or Grasp? Only “Bass” is cited, but where can to find them?  Measuring functional dependency The game have one game only, thus, some calculus were not used.  Clustering Should to explain how apply clustering algorithm  Allocating Classes to Components The coupling and cohesion parts are for be equal eith the Use Case coupling?
