2. What Makes “Good” Architecture?
 No inherently good or bad Architecture
 Architectures are either more or less fit for some
stated purpose
 Architectures must be evaluated
 Architecture should follow basic guidelines

3. 1. Identify leader
2. Pre-requisites: Functional requirements, Prioritized list of quality
attributes
3. Be well documented
4. Circulated to stakeholders
5. Analyzed for throughput and attainment of quality attributes
6. Lend itself to Incremental implementation
7. Should have minimal resource contention areas, the resolution of which
should be clearly specified.

4. 1. Features well-defined modules
2. Has well-defined interface for each module
3. Achieve quality attributes using well-known tactics
4. Be independent of specific commercial product or tool
5. Separation of data producers from data consumers
6. For parallel processing systems
 Define processes/tasks to be carried out on each thread
 Tasks can be moved from one processor to another at runtime
7. Architecture should feature a small number of interaction patterns i.e. should
do the same things same way throughout.

5.  Architecture is more than the result of the
functional requirements
 Influence on architecture
 Architecture Business Cycle
 Architecture guidelines to promote
 Best possible design for system
 System success
