The 5 Tools

From symptoms to action plan,
all in one integrated flow

Each tool answers a different question and passes its results to the next. For the first time, all on a single web platform.

Diagnosis · What to change?

Current Reality Tree

Connect the symptoms you observe to their root causes via cause-effect relationships. Identify the core problem that generates most undesirable effects.

Current Reality TreeCRTRoot CauseUDEs
Conflict · What to change to?

Evaporating Cloud

Frame the conflict as two legitimate needs in tension, uncover the hidden assumptions behind each arrow, and find the injection that resolves it without compromise.

Validation · What to change to?

Future Reality Tree

Simulate what will happen if you apply the injection before acting. Verify it produces the desired effects, detect negative branches and reinforcing loops.

Transition Tree

Break down each intermediate objective into concrete action steps with full logic: action, expected effect, need and reason for each step.

Everything connected

Cloud injections flow into the FRT. PRT objectives feed the TT. The CRT's root problem reaches the Cloud. One project, one flow, full traceability.

Process

From a complex problem
to an executable plan

Goldratt's methodology in four steps, guided and assisted by AI at every point of the way.

1

Diagnose with the CRT

List the symptoms you observe (undesirable effects) and connect them downward until you find the root cause. AI helps you identify causal relationships and propose root-cause candidates.

2

Frame and solve the conflict with the Cloud

Turn the root problem into a conflict of two legitimate needs. Identify the assumptions behind each arrow and find the injection —the idea that breaks the false assumption and resolves the dilemma without compromise.

3

Validate the solution with the FRT

Simulate the chain of effects your injection will produce. Confirm it reaches the desired effects, detect possible negative branches and bring them under control before acting.

4

Plan and execute with PRT and TT

The PRT maps real obstacles and the order to overcome them. The TT turns each intermediate objective into action steps with full logic. In the end you have an executable plan anyone can follow.

AI Assistance

AI assists. You decide.

AI never replaces your reasoning. It accelerates, challenges and documents it. Always with your own API key, no hidden costs.

Suggests causes and effects

In the CRT and FRT, AI proposes causal links and detects gaps in your reasoning. You accept, edit or discard each suggestion.

Uncovers hidden assumptions

In the Evaporating Cloud, AI plays devil's advocate: why do we believe we need exactly this? Which assumption can we break?

Searches for negative branches

In the FRT, AI proposes what could go wrong if you apply the injection. Better to discover it here than in production.

Generates action plans

In the TT, AI breaks each objective into concrete steps with action, effect, need and reason. The skeleton, for you to refine.

Your API key, your cost

On paid plans you connect your own Anthropic (or compatible) API key. No limits, no markup. The AI cost is directly yours.

Everything is recorded

Every suggestion, every accept/reject decision, stays in the reasoning log. Full traceability of how you reached each conclusion.

Why TOC Thinking Tools?

What other tools

Use cases

Useful in any context where
there is a complex problem

The Theory of Constraints is not just for manufacturing. Its thinking tools apply to any system with conflicts and constraints.

Operations and production

Identify the real bottleneck and subordinate everything else to it.

Business strategy

Resolve conflicts between departments or contradictory strategic priorities.

Negotiation and conflict

Find win-win solutions where both sides seem to be right.

TOC training

Learn and teach the Thinking Processes with guided real cases.

Improvement consulting

Document reasoning client by client with a traceable history.

Decision making

Structure any complex dilemma with verifiable cause-effect logic.

Frequently asked questions

What people usually ask

Not required. Each tool includes full contextual explanations based on Goldratt's exact methodology: what it is, when to use it, how to read it and what mistakes to avoid. You can learn while solving your real problem.

Sister app

From diagnosis to project execution

TOC Thinking Tools diagnoses the problem and designs the solution. CCPM Manager executes the project using Critical Chain methodology.

Both tools complement each other: use the Thinking Processes to identify the root cause and define the action plan, then manage its execution with Critical Chain — Fever Chart, buffer management, Gantt diagram, and real-time team tracking.
