VIKAS

2. KEY WORDS: Quality attributes models Architectural styles
Architecture Analysis
Quality attributes models
Architectural styles

3. Advantages: software development cycle
1: The ATAM can be done early in the
software development cycle
2: It can be done inexpensively and quickly
3: It identifies trends were some architectural
parameters is correlated with the measurable
quality attribute of interest

4. ATAM STEPS Step 0- planning/ information exchange
Step1-scenario brainstorming
Step2-Architectural presentation
Step3-Scenario coverage checking

5. ATAM STEPS Step4-Scenario grouping and prioritization
Step5-Map high priority scenarios onto architecture
Step6-Perform quality attribute-specific analysis

6. ATAM STEPS Step7-Identify trade-off points
Step8-Consolidate findings and develop action plans

7. 1: What are the measurable or observable manifestations
of the attribute ?
2: What are the attribute relevant stimuli or events to which
the architecture must respond ?
3: What are the characteristics of the architecture that
affect the observable manifestation ?

10. 1:For what functions of the system is performance not
important ?
2: For those functions for which performance is not important
what is the consequence of the extremely long
response times ?
3: How is the performance impacted by scaling up the
work land ?

11. Three quality attributes
1: Availability
2: modifiability
3: performance
