1. What is the primary purpose of the Iceberg Tool?
A. To identify only the most recent event
B. To move analysis from visible events toward patterns and underlying structures
C. To calculate the cost of a business
D. To identify individual employees responsible for a problem
Answer: B. To move analysis from visible events toward patterns and underlying structures
Complete solution:
The Iceberg Tool helps a systems thinker look beneath an observable event. The analysis
generally moves from events → patterns → underlying structures, allowing the student to
explain why the problem keeps occurring rather than merely describing what happened.
2. Which level of the Iceberg Tool contains directly observable occurrences?
A. Events
B. Patterns
C. Structures
D. Mental models
Answer: A. Events
Complete solution:
Events are the visible occurrences within a system. For example, a company experiencing
increasing debt is an event. Systems thinking then asks what recurring patterns and structures
produced that event.
3. What distinguishes a pattern from an event?
A. A pattern describes behavior over time
B. A pattern is always a single occurrence
C. A pattern is unrelated to events
D. A pattern is always a solution
Answer: A. A pattern describes behavior over time
, Complete solution:
An event is a specific occurrence, whereas a pattern describes repeated or changing behavior
across multiple events.
4. What should a student look for when identifying patterns in a case study?
A. Repeated or progressively changing behaviors
B. Only the names of people involved
C. Grammar errors
D. A solution before analyzing the problem
Answer: A. Repeated or progressively changing behaviors
Complete solution:
The objective is to identify what keeps happening or how something changes over time. This
provides the foundation for selecting and interpreting the appropriate Behavior Over Time
graph.
5. What is meant by an underlying structure?
A. The deeper relationships, rules, resources, incentives, or conditions that contribute to system
behavior
B. The title of the case study
C. A single event
D. A personal opinion
Answer: A. The deeper relationships, rules, resources, incentives, or conditions that
contribute to system behavior
Complete solution:
Underlying structures explain why patterns occur. They may include resource constraints,
policies, incentives, relationships, processes, or other system arrangements.
6. Which sequence best represents the Iceberg Tool?
A. Solution → event → pattern
B. Event → pattern → underlying structure
C. Structure → event → solution only
D. Stakeholder → budget → event
Answer: B. Event → pattern → underlying structure
