Quality Dimensons

Palladio supports overall four quality dimensions − each with multiple result metrics:

  1. Performance
    • Response Time
    • Throughput
    • Resource Utilization
  2. Reliability
    • Probability of failure on demand
  3. Maintainability
    • Maintenance efforts per design alternative
    • Maintenance costs per design alternative
  4. 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).
