The following is the domain checklist:

• Have hardware, network, PCs, system software, and DBMS been chosen which are geared to one another and to the applications?
• Is a dual set of hardware, and so on available for alternative use?
• Have you mapped all the system's functional elements to a type of hardware device? Have you mapped them to specific hardware devices if appropriate?
• Is the role of each hardware element in the system fully understood? Is the specified hardware suitable for the role?
• Have you established detailed specifications for the system's hardware devices? Do you know exactly how many of each device are required?
• Have you identified all required third-party software and documented all the dependencies between system elements and third-party software?
• Is the network topology required by the system understood and documented?
• Have you estimated and validated the required network capacity? Can the proposed network topology be built to support this capacity?
• Have network specialists validated that the required network can be built?
• Have you performed compatibility testing when evaluating your architectural options to ensure that the elements of the proposed deployment environment can be combined as desired?
• Have you used enough prototypes, benchmarks, and other practical tests when evaluating your architectural options to validate the critical aspects of the proposed deployment environment?
• Can you create a realistic test environment that is representative of the proposed deployment environment?
• Are you confident that the deployment environment will work as designed?
• Have you obtained external review to validate this opinion?
• Are the assessors satisfied that the deployment environment meets their requirements in terms of standards, risks, and costs?
• Have you checked that the physical constraints (such as floor space, power, cooling, and so on) implied by your required deployment environment can be met?
