ATAMtyökaluja

ATAMtyökaluja refers to a set of tools and methodologies used for the purpose of Architectural Trade-off Analysis Method. This method is employed in software engineering and system design to evaluate and compare different architectural decisions based on their impact on various quality attributes. Quality attributes, also known as non-functional requirements, can include aspects like performance, security, maintainability, usability, and scalability.

The core idea behind ATAM is to systematically identify potential risks associated with architectural choices and to ensure that these choices adequately support the system's business goals. The process typically involves stakeholders, architects, and developers working together. They define the critical quality attributes and business drivers. Then, scenarios are developed that illustrate how these attributes are expected to manifest. These scenarios are used to evaluate candidate architectural approaches.

ATAMtyökaluja can encompass various techniques such as scenario-based analysis, scenario voting, and architectural pattern identification. The goal is to arrive at an architecture that balances competing quality attribute requirements. For instance, a decision that enhances performance might negatively affect maintainability, and ATAM helps to quantify and understand these trade-offs. The output of an ATAM evaluation is usually a report detailing the identified risks, trade-offs, and recommended actions to mitigate risks and improve the architecture. This structured approach aids in making informed decisions early in the development lifecycle, reducing the cost of changes later on.
