Explanation
A force field analysis diagram shows the opposing forces to the solution and ranks their force, their power over the solution decision.
Answer B is incorrect. A tornado diagram is used in sensitivity analysis. It's called a diagram because the bar
chart is listed vertically and often looks like a tornado when complete.
Answer C is incorrect. A stakeholder matrix can be used in stakeholder management to show concerns,
threats, and strategies for managing the stakeholders.
Answer D is incorrect. A Pareto chart is a bar chart that ranks problems or categories from largest to smallest.

Explanation
Data modeling is the best answer, as this approach describes the concepts and relationships relevant to the solution or business domain.
Answer A is incorrect. The data flow diagram shows how information flows through a system.
Answer B is incorrect. The business rules analysis examines how business rules may be implemented and

Explanation
Before Ralph can begin defining the requirements at a deeper level, the initial requirements must be formally approved by the relevant stakeholders.
Answer B is incorrect. The initial requirements do not need to undergo a feasibility study at this time.
Answer D is incorrect. The Delphi Technique is useful to gain consensus on requirements, but it's not a
mandatory activity or needed (usually) with the initial requirements.
Answer A is incorrect. The requirements don't need to be tested for time, cost, quality, and risk at this time.

Explanation/Reference:
Tracing a requirement is the linkage of the requirements to all the parts of solution including its execution and creation.
C is incorrect. This is not a valid definition of tracing a requirement. Requirement tracing does not
consider risk, cost, quality, and other scope elements.
A is incorrect. This is not a valid definition of tracing a requirement. It does not examine its
position in the project WBS.

Explanation/Reference:
Visual learners are people that learn best by observing a model of the problem or visual aids to demonstrate the problem.
B is incorrect. Auditory learners describe people that learn best by oral and written
communications.
A is incorrect. Kinesthetic learners learn best by experiencing the topic, hands-on activities, and
walk-throughs of the identified topic.
C is incorrect. This is not a valid learning type.
