• Requirements validation

Which two of the following types of documentation are best suited to document the system context?

• Textual description (continuous text)

• State diagram

• Data flow diagram

• Use case diagram

Which aspects need to be considered when defining the system boundary and the context boundary?

• The system

• The system context

• The irrelevant environment

• The interfaces between system and system context

Which of the below are included in the definition of system and system boundary?

• The affected software components

• The interfaces between the system and its environment

What will be influenced by this finding?

• The system boundary

• The context boundary

• System interfaces

• Gray zone of the system boundary

Which two of the following statements related to requirements engineering will most likely be the result of not taking into account the system context correctly?

• Increased customer satisfaction

• Cost reduction by focusing on the essentials

• System failure during operation because of unforeseen situations

Which of the following statements on quality requirements are true?

• Quality requirements refer to the process of creating software and not to the
