Introduction to the ATAM Method

Introduction to the ATAM Method

1. What is ATAM?

ATAM is a scenario-based evaluation Method. Its full name is Architecture TradeOff Analysis Method ATAM (Architecture trade-offs Analysis)

2. ATAM Evaluation Method

The purpose of the ATAM method to evaluate the software architecture is to evaluate the Decision-Making results based on the system quality attributes and business needs. ATAM wants to reveal that the architecture meets the quality objectives, architects can better understand the connection between quality objectives. That is, how to weigh multiple goals

3. ATAM participants

Developers, field experts, testers, customer representatives, users, etc.

4. How to launch evaluation activities

The evaluation activities are divided into four phases.

1. Description and Description phase 2. Investigation and Analysis Phase 3. Test phase 4. Report phase

1. Description Method

For example, if a participant introduces the ATAM method, it is necessary to reserve some time to answer questions in order to achieve the desired effect.

2. Describe the business motive

Introduce the system from the business perspective, including the most important functions of the system and some related restrictions

3. Describe the architecture

Introduce the architecture of the architecture, including technical constraints and methods that have met the quality attribute. It should not be too long, but be clear.

4. Determine the architecture Method

5. Generate a quality utility tree

Determine the system's most important quality attribute objectives and sort these quality attributes by priority

6. Analysis Architecture

You can analyze each architecture, perform a preliminary analysis on the quality attributes of the method, and obtain a list of methods or styles (risks, sensitive points, and trade-offs)

7. Scenario

Scenarios play a leading role in the ATAM test phase,

8. Analysis Architecture

Architectural Design maps the most advanced scenarios to the described architecture, and explains how the architecture design helps to implement the scenario.
