Checkpoints: Workload Analysis Model

Estimates of system performance exist.
System performance estimates have been validated using architectural prototypes, especially for performance-critical requirements.
'Bottleneck objects' have been identified and strategies defined to avoid performance bottlenecks.
Collaboration message counts are appropriate given the problem domain; collaborations appear to be well-organized and as simple as possible.
Executable start-up (initialization) is within acceptable limits as defined by the requirements.
All nominal and maximal performance requirements are specified.
Tests exist to evaluate the performance of the system against performance requirements
Performance requirements are reasonable and reflect real constraints in the problem domain; their specification is not arbitrary.
