The tutorial starts with the definition of relevant terms. It goes on to present the basic concepts required for architecture analysis and (re)design. Among these are known heuristics of how to modularize software systems and how to describe architectures, architectural patterns, and hot spot analysis. The analysis activity is crucial in ensuring that a large and costly development project meets its quality goals. Such an analysis can be used for acquisition, for new projects, or for planned maintenance and reengineering activities. The tutorial introduces two methods for architecture analysis. Case studies exemplify the application of these methods. A thorough analysis also forms the precondition of an architecture evolution of legacy systems. A case study illustrates how small object-oriented frameworks, called framelets, help in the process of refactoring replicated code fragments.

An experience report on the benefits and costs of applying the presented aspects of architecture-centered design in various projects concludes the presentation.
