Iasa Certification Level Learning Objective
CITA- Foundation
  • How do you measure testability? Supportability? Understandability?
  • Whose responsibility is that development-related attributes are considered during the design phase?
  • How should you balance extensibility with the need to deliver on time and budget?
  • What are the side effects of poorly designed development-related quality attributes?
CITA – Associate
  • Where do you draw the line between extensibility and additional cost?
  • What is considered a well-maintained system?
  • Quantify the value of flexibility/extensibility attributes.
  • What is the difference between customization and personalization?
CITA – Specialist
  • What was your “design for operations” strategy?
  • What specification for maintainability did you follow to claim that the system was easy to maintain?
CITA – Professional
  • Was your solution flexible or extensible – or both? Explain.
  • When Operations rejected the hand-over due to poor manageability, what were your options?
