What is the primary purpose of a causal loop diagram in systems thinking?

To calculate the exact numerical values of system variables over time

To replace statistical process control charts in monitoring quality

To list all stakeholders and their responsibilities in a project

To visualize the feedback structures and causal relationships within a system

In a causal loop diagram of an Agile testing process, a reinforcing loop represents 'more test automation → faster releases → more customer feedback → more test automation'. What is the most likely long-term behavior of this system if no balancing loops are present?

Stabilization at a sustainable level

Oscillation between high and low automation

Exponential growth in automation and releases

An Agile team is experiencing a 'death spiral' where missed deadlines lead to reduced testing, which increases defects, leading to more missed deadlines. They want to use a causal loop diagram to identify a leverage point to break this cycle. Which intervention would most directly target the reinforcing loop?

Eliminate all manual testing to save time

Reduce the scope of each sprint to avoid missed deadlines

Increase the number of testing tools available to the team

Add a balancing loop that increases testing time when defects rise

When constructing a causal loop diagram from a system description, what is the first step?

Identify the key variables that influence the system's behavior

In an Agile testing context, what is a leverage point in a causal loop diagram?

A variable that is easy to measure

A feedback loop that is balancing

A variable that has the most links in the diagram

A place where a small change can produce a large, lasting improvement in the system

Causal Loop Diagram CT-ATLAS Practice Questions (Page 3)

Part of the Continuous Improvement of Quality and Testing domain, which makes up ~17% of our current practice bank. ISTQB does not publish an official question count, but from its 120-minute exam (~50–80 total, ~9–14 in this domain), expect 2–3 from this objective — we provide 16 practice questions to prepare you well beyond it.
