(Architecture Tradeoff Analysis Method) . The ATAM, like the SAAM, is a scenario-based method. CMU/SEI-2001-TN-009 1 1 Introduction The software architecture of a system significantly influences the overall functionality, performance, and quality of that system. Architecture Tradeoff Analysis Method 1. The brilliant minds at the Software Engineering Institute at Carnegie Mellon University developed the Architecture Tradeoff Analysis Method (ATAM) as an iterative process to help mitigate risk when a software project is in its initial stages. SM Architecture Tradeoff Analysis Method and ATAM are service marks of Carnegie Mellon University. However, unlike the SAAM, the ATAM focuses on multiple quality attributes (currently modifiability, availability, security, and performance) and is aimed at locating and analyzing tecture Tradeoff Analysis Method (ATAM). The Architecture Tradeoff Analysis Method (ATAM) is a method for evaluating software architectures relative to quality attribute goals. Architecture tradeoff analysis method (ATAM) The Architecture Tradeoff Analysis Method (ATAM) is a method for evaluating software architectures relative to quality attribute goals. In software engineering, Architecture Tradeoff Analysis Method (ATAM) is a risk-mitigation process used early in the software development life cycle.. ATAM was developed by the Software Engineering Institute at the Carnegie Mellon University.Its purpose is to help choose a suitable architecture for a software system by discovering trade-offs and sensitivity points. The purpose of ATAM is: to assess the consequences of architectural decision alternatives in light of quality attribute requirements. SM Architecture Tradeoff Analysis Method and … Then from these drivers quality attributes and business scenarios are created. Wargame 2000 system and present important results and benefits. The use of software architecture evaluations early in Process of Architecture Tradeoff Analysis Method : The ATAM process starts with bringing all the stakeholders to find business drivers like system goals, constraints, system functionality, and desired non-functional properties. Abstract: This paper presents the Architecture Tradeoff Analysis Method (ATAM), a structured technique for understanding the tradeoffs inherent in the architectures of software-intensive systems. While architecture evaluation is valuable early in the development life cycle, this case study illustrates that such evaluations are also useful when a system is well into development. ATAM is a method for evaluating architecture-level designs that consid-ers multiple quality attributes such as modifiability, perfor-mance, reliability and security in gaining insight as to whether the fully fleshed out incarnation of the architecture will meet its requirements. SEI has developed the Architecture Tradeoff Analysis Method (ATAM) over several years.

Method evaluations expose architectural risks that potentially inhibit the achievement of an organization’s business goals. Artifacts/Outputs Architecture Tradeoff Analysis Method ATAM a set of architectural approaches identified a "utility tree"—a hierarchic model of the driving architectural requirements the set of scenarios generated and the subset that were mapped onto the architecture a set of SM Architecture Tradeoff Analysis Method and ATAM are service marks of Carnegie Mellon University. viii CMU/SEI-2001-TN-009 . frequently must be acquired and verified using architecture extraction and conformance testing methods [Kazman 99]), applying the ATAM results in increased understanding of the quality attributes of the system.
