Requirements Modeling and Testing Quiz

Requirements Engineering

• Transforming a requirements model into natural language text is called paraphrasing.

Requirements Validation and Testing

• The activity of inventing tests for requirements is called requirements testing.
• Requirements validation should check the near final draft of the requirements.
• Requirements validation is a major concern in view of error diversity, frequency, criticality, and cost.
• The 5 different validation techniques are:
  • Reviews and inspections
  • Prototyping
  • Model validation
  • Testing
  • Formal checking

Checklists

• A list of generic questions designed to detect typical defects found in a requirements document is known as a defect-driven checklist.

RE Tools

• RE tools can support the following activities:
  • Elicitation (e.g., analysis of textual artifacts)
  • Documentation (generating and editing requirements work products)
  • Modeling (primarily model editors)
  • Management (Store and retrieve, prioritize, trace,...)
  • Validation (finding quality problems, simulators, model checkers,...)
• RE tools can have different support levels, including:
  • General purpose
  • Database-level
  • Language & method-based
• An RE tool does not automatically improve productivity.

RE Standards

• An RE standard contains the "standard way" of doing RE, processes/products involved in RE, and characteristics/attributes of well-formed requirements.
• The IREB CPRE (Certified Professional for Requirements Engineering - foundation level) is a de facto basic RE BoK, consisting of a syllabus, a handbook, and a glossary.

Ethical Principles

• Ethical principles in RE include:
  • No harm
  • For the good
  • Fairness
  • Autonomy
  • Transparency

AI in RE

• AI can do the following for RE:
  • Primary means: processing natural language text with machine learning to find and classify, extract, and find smells in requirements.
  • Recommend: further stakeholders/stakeholder roles, configure requirements in a product line, etc.
  • Analyze: automated impact analysis when requirements change.
  • Generate: propose requirements, acceptance criteria, and solutions for a given problem.
