Here is a master list of the questions synthesized from the provided sources, categorized by their function in the inquiry process (Ontology, Diagnosis, Design, Strategy, and Epistemology).

I. Ontology & Identity: Defining the System

These questions determine the boundaries, nature, and fundamental identity of the system under observation.

What is the System-in-Focus? (Determining the precise organization and boundaries being modeled)[1].

What business are we in? (Identifying the identity and recursive location of the system)[2],[1].

What is the system? (versus What does the system do?)[3],[4].

Is the system “simple” (a mechanism) or “complex” (an organism)?[5].

What is the nature of the system? (Determining the relationship between cause and effect to identify the domain: Simple, Complicated, Complex, or Chaotic)[6].

Is the system governed by forces (Pleroma) or by information/differences (Creatura)?[7].

What problems do you see that lie ahead? (The Triggering Question for defining a Problematique)[8].

Who is the Problem Owner?[9],[10].

Where is the “Cut” between the observer and the observed? (The Epistemic Cut)[11].

II. Diagnosis & Causality: Understanding “Why”

These questions investigate the current state, constraints, and underlying causes of the situation.

What is the case? (The Reality Judgment)[12],[13].

Why is it not as it ought to be? (Determining the level of the problem)[14].

What is stopping us from doing it? (Identifying constraints or the state of nature)[15].

What is the root cause? (Recursively asking “Why?” to find the fundamental cause)[16].

What to change? (Identifying the core problem or constraint responsible for symptoms)[17].

Why this rather than that? (The specific interrogation of constraints)[18].

What stops this from being anything else? (Negative explanation)[19].

What difference makes a difference? (Identifying the specific contrast that triggers a response)[20].

Does this activity exist in the real situation? (Comparing models to reality)[21].

How does it work? (Structural analysis) vs. Why does it work the way it does? (Functional/Systems analysis)[22],[4].

III. Strategic Inquiry: Deciding How to Act

These questions guide decision-making, planning, and the selection of interventions.

What to change to? (Designing the solution/injection)[23].

How to cause the change? (Execution and overcoming resistance)[24].

What can we do about it? (Identifying feasible actions)[15].

What if this action is taken? (Deliberation and consequence modeling)[25],[26].

Which action should be chosen? (Optimization)[27].

How do we make decisions? (Selecting the framework: e.g., Sense-Analyze-Respond vs. Probe-Sense-Respond)[28],[29].

What resources (Substance, Field, Space, Time, Information) are available?[30].

Who can (has enough power to) get something useful done about it?[31].

If you could speak to an oracle who knows the future, what questions would you ask? (Uncovering risks and uncertainties)[32].

If you were away for three months, what would your replacement need to know or monitor? (Revealing implicit values and operations)[33].

IV. Design & Innovation: Creating the New

These questions drive the creation of new forms, systems, or solutions.

What is the fundamental goal of design?[34].

If this work lived up to its fullest potential, what would be possible?[35].

What is the Ideal Final Result? (Does the system perform the function without existing?)[36].

What is the System Contradiction? (If I improve A, does B worsen?)[37].

Can we separate the contradictory states in Time, Space, or Condition?[30].

Does this element have a relationship with that element? (Structuring the system via Generic Questions)[38].

How can we design improvement in large systems without understanding the whole system?[39].

What is the “Quality Without a Name”?[34].

Should measure ‘A’ become part of the plan? (Followed by: Will it work? Are prerequisites available? What are the side effects?)[14],[40].

V. Ethics, Values, & Purpose: The Normative Dimension

These questions address the “ought,” the values, and the human element of systems.

What ought to be the case? (The Value Judgment)[41],[13].

What is the standard? (Defining the compass/goal)[42].

Why is this important? (Laddering up to goals/values)[43].

Who benefits and who suffers? (The “Customers” in CATWOE)[44].

Who ought to be involved in making a decision?[45].

What is an honest man? and What need I do to become one?[46].

What does this situation require of me? (The existential question)[47].

Do you really and sincerely believe that [Subject] has Quality? (The “seed crystal” question)[48].

VI. Epistemology & Learning: Structuring Knowledge

These questions determine how we know what we know and how we frame our inquiry.

What is the question that this statement is meant to answer? (The logic of Question and Answer)[49].

How is this possible? (Replacing the ontological “What is X?“)[50].

Is the relationship between cause and effect self-evident, discoverable, or only coherent in retrospect?[6],[51].

What is the pattern which connects?[52].

Is this message a communication, or is it a meta-communication? (Checking Logical Types)[53].

What specific unobserved phenomenon can be inferred from this text? (Content Analysis)[40].

Am I apart from the universe? vs. Am I part of the universe? (First vs. Second-order Cybernetics)[54].

What is the “Error of the Third Kind”? (Solving the wrong problem precisely)[55].

What must I assume is ‘true’ of this stakeholder for my plan to succeed? (Assumption Surfacing)[56].

What are all the possible behaviours that it can produce? (Cybernetic inquiry)[57].
