Typical Acceptance Criteria

Scenario Response Measures for “Deployability” from [Bass et al.]

Bass et al. define deployability as a property, and somehow omit other operational characteristics.

Cost in terms of

  • Number, size and complexity of affected artifacts
  • Average/worst-case effort
  • Elapsed clock or calendar time
  • Money (direct outlay or opportunity cost)
  • New defects introduced

Extend to which this deployment affects other functions or quality attributes.

  • Number of failed deployments
  • Repeatability of the process
  • Traceability of the process
  • Cycle time of the process
