Architectural decisions influence and impact the non-functional characteristics of a system. Each architectural decision describes a concrete, architecturally significant design issue (a.k.a. design problem, decision required) for which several potential solutions (a.k.a. options, alternatives) exist.
Architectural analytics is a field of study focused on discovering and identifying meaningful patterns within architecture.Architectural analytics can include the systematic study of the elements and principles that constitute a building or structure, such as form, function, space planning, materials, technology, and cultural context, to understand its design, function, and cultural significance.
When discussing architecture, the terms non-functional requirements or quality attributes are often used. [2] However, recent empirical studies show that, for a software system , not all non-functional requirements affect its architecture , and functional requirements can also affect its architecture.
It combines aspects from scenario-based design review techniques, such as the architecture tradeoff analysis method (ATAM) and the software architecture analysis method (SAAM), as well as active design reviews (ADR). [2]
This analysis can be converted to risk themes and their impacts whereupon the process can be repeated. With every analysis cycle, the analysis process proceeds from the more general to the more specific, examining the questions that have been discovered in the previous cycle, until the architecture has been fine-tuned and the risk themes have ...
Software architecture analysis method (SAAM) is a method used in software architecture to evaluate a system architecture. It was the first documented software architecture analysis method, and was developed in the mid 1990s to analyze a system for modifiability, but it is useful for testing any non-functional aspect.
DMAIC, IDOV and Six Sigma may still be used during depth-first plunges into the system architecture analysis and for "back end" Six Sigma processes; DFSS provides system design processes used in front-end complex system designs. Back-front systems also are used. This makes 3.4 defects per million design opportunities if done well.
A Pattern Language: Towns, Buildings, Construction is a 1977 book on architecture, urban design, and community livability.It was authored by Christopher Alexander, Sara Ishikawa and Murray Silverstein of the Center for Environmental Structure of Berkeley, California, with writing credits also to Max Jacobson, Ingrid Fiksdahl-King and Shlomo Angel.
