Quality Dimensons
Palladio supports overall four quality dimensions − each with multiple result metrics:
- Performance
- Response Time
- Throughput
- Resource Utilization
- Reliability
- Probability of failure on demand
- Maintainability
- Maintenance efforts per design alternative
- Maintenance costs per design alternative
- Costs
- Costs for the realisation of a certain software architecture
The support of multple quality dimensions allows informed trade-off decisions (e.g. balance performance and reliability).
All quality dimensions can be analysed based on a single software architecture model (the Palladio Component Model, PCM).
