The following is the domain checklist:

• Have you defined how flexibility requirements influenced the specified functionality and how it is distributed between the subsystems?
• Does the functional specification explicitly describe how future changes to the system should be implemented to preserve flexibility?
• Does the system use data coded for data entry, error handling, or information messages?
• How does the system personalise the user experience?
• Does the system provide any disability access support?
• How straightforward is customization and configuration?
• Is the architecture designed to accommodate future changes?
• Does the architecture avoid unnecessary redundancy? Have the following been considered as part of the approach?
  • Rationalization
  • Consolidations
• Is the architecture independent of the technology stack that will be used to implement it?
• Are architecture decisions and assumptions documented explicitly and motivated?
• Are there any missing or incomplete capabilities and/or components?
• Have known design risks been identified, analysed, and planned for or mitigated?
• Are components well-defined, including their functionality and their interfaces to other components?
