Checklist: Supporting Requirements
This checklist is used to verify that all types of supporting requirements are considered.
Relationships
Check Items
Have global Functional requirements that will be implemented in the next iteration been captured and validated?
  • Are functional requirements that affect multiple use cases identified? For example, all use cases may be subject to access control, audit trails, general responses to abnormal situations (overflow, communication facilities, error handling and recovery, and so on).
  • For each of these requirements, are they behavioral and could be better captured in a common use case?
  • For each of these functions, is it clear how input and shared data generate output and shared data?
Have Usability requirements that will be implemented in the next iteration been captured and validated?
  • Are functional requirements that affect multiple use cases identified? For example, all use cases may be subject to access control, audit trails, general responses to abnormal situations (overflow, communication facilities, error handling and recovery, and so on).
  • For each of these requirements, are they behavioral and could be better captured in a common use case?
  • For each of these functions, is it clear how input and shared data generate output and shared data?
Have Reliability requirements that will be implemented in the next iteration been captured and validated?
  • Have reliability requirements been specified as measurable requirements or prioritized design goals?
  • Is error checking and recovery required?
  • Are undesired events considered and their required responses specified?
  • Are initial or special states considered (such as cold starts or abnormal termination)?
Have Performance requirements that will be implemented in the next iteration been captured and validated?
  • Have the Resource and Performance Margin requirements been stated (for example, speed, response time, recovery time of various software functions)?
Have Supportability requirements that will be implemented in the next iteration been captured and validated?
  • Are there any requirements that will enhance the supportability or maintainability of the system being built?
Have Constraints that must be considered in the next iteration been captured and validated?
  • Are there any required standards in effect, implementation language, policies for database integrity, resource limits, operating environments, and so forth?
  • Has the use of inherited design or code or pre-selected tools been specified?
Have external interfaces that must be considered in the next iteration been identified?
  • Is it clear how the software interacts with people, the system's hardware, other hardware, and other software?
  • Have all critical data elements that cross system boundaries been identified for the scenarios that will be implemented in the next iteration?
Have Business Rules that will be implemented in the next iteration been captured and validated?
  • Are the rules relevant to the use cases identified (data validation rules, formulas, flow decisions)?
Have applicable Standards and Regulatory Compliance requirements that must be considered in the next iteration been identified?
  • Have all requirements that are derived from existing standard and regulations been specified?
