What Is TRIZ?
TRIZ (pronounced “trees”) stands for the Theory of Inventive Problem Solving. It was developed by Genrich Altshuller, a Soviet engineer and inventor, in the 1940s.
Altshuller studied thousands of patents to understand how innovators solved technical problems. He discovered that most inventive solutions followed a set of universal patterns rather than random creativity. From this research, he built the TRIZ framework.
The goal of TRIZ is simple: use systematic logic to generate innovative ideas.

The Core Idea Behind TRIZ
At the heart of TRIZ lies one insight — innovation follows patterns.
Altshuller found that nearly all inventive solutions resolved contradictions without compromise.
A contradiction occurs when improving one aspect of a system makes another aspect worse. For example:
- Increasing production speed may reduce quality.
- Improving safety may increase cost.
- Reducing waste may slow output.
TRIZ teaches us how to resolve contradictions so that both sides improve together.
Why TRIZ Matters in Process Improvement
Lean Six Sigma projects focus on reducing waste, defects, and variation. However, some problems resist simple fixes. Traditional brainstorming can stall when trade-offs seem unavoidable.
That’s where TRIZ shines.
By applying structured principles, TRIZ helps teams:
- Eliminate design contradictions
- Find innovative process solutions
- Reduce reliance on trial and error
- Accelerate improvement cycles
Instead of guessing what might work, teams can leverage proven patterns of innovation to reach better outcomes faster.
The TRIZ Knowledge Base
TRIZ organizes its knowledge into several key tools. These tools guide problem solvers through systematic innovation.
| TRIZ Tool | Purpose | Example Use |
|---|---|---|
| 40 Inventive Principles | Suggests generic innovation strategies | Improving throughput without new equipment |
| Contradiction Matrix | Links engineering parameters to innovation principles | Balancing speed and quality |
| Ideal Final Result (IFR) | Defines the perfect solution | Designing a process with zero defects |
| Function and Attribute Analysis | Maps cause–effect relationships | Understanding waste sources |
| ARIZ (Algorithm for Inventive Problem Solving) | Step-by-step problem-solving algorithm | Solving complex design challenges |
| Trends of Technological Evolution | Predicts future system improvements | Anticipating automation trends |
Each of these tools helps you move from problem identification to solution generation in a logical, data-driven way.
The 40 Inventive Principles Explained
The 40 Inventive Principles are the foundation of TRIZ. They describe recurring strategies used across industries to resolve contradictions.
Here are a few of the most useful ones for process improvement:
| Principle | Description | Example in Process Improvement |
|---|---|---|
| 1. Segmentation | Divide a system into parts | Break a production line into modular cells |
| 3. Local Quality | Adapt specific areas instead of the whole | Optimize temperature only at critical steps |
| 10. Preliminary Action | Prepare actions in advance | Pre-stage materials before changeovers |
| 15. Dynamics | Make systems adjustable | Use flexible fixtures for multiple products |
| 25. Self-service | Enable systems to serve themselves | Automated calibration or self-cleaning machines |
| 28. Mechanics Substitution | Replace mechanical with sensory or digital | Use vision systems instead of manual inspection |
| 35. Parameter Change | Modify operating conditions | Change pressure or speed dynamically |
Each principle gives teams a structured way to think differently about the same problem.
The Contradiction Matrix
The Contradiction Matrix is one of TRIZ’s most powerful tools. It links engineering parameters (like speed, accuracy, or cost) to inventive principles that historically resolved those trade-offs.
For example, suppose you want to increase speed without reducing accuracy. The Contradiction Matrix will suggest relevant inventive principles—perhaps “Segmentation,” “Dynamicity,” or “Feedback.”
Here’s a simplified illustration:
| Improving Parameter | Worsening Parameter | Suggested TRIZ Principles |
|---|---|---|
| Speed | Accuracy | 15. Dynamics, 23. Feedback, 28. Mechanics Substitution |
| Safety | Cost | 10. Preliminary Action, 2. Taking Out, 25. Self-service |
| Reliability | Complexity | 6. Universality, 35. Parameter Change, 1. Segmentation |
This table saves time by showing what has worked before in similar contradictions.
TRIZ and the Ideal Final Result (IFR)
TRIZ promotes defining an Ideal Final Result (IFR) before looking for solutions.
The IFR describes the perfect process outcome, assuming no constraints. It asks:
“What would the system do if it worked perfectly on its own?”
By thinking in terms of ideals, teams move beyond incremental change and explore radical improvements.
For instance:
- IFR for inspection: “The product verifies its own quality.”
- IFR for scheduling: “The process schedules itself optimally.”
- IFR for maintenance: “The equipment repairs itself automatically.”
These statements sound futuristic but guide practical innovation. Teams can then find small, realistic steps that move closer to the IFR.
Steps in the TRIZ Process
TRIZ follows a logical problem-solving sequence. Each step helps clarify what the problem truly is and how to approach it creatively.
| Step | Description | Output |
|---|---|---|
| 1. Define the Problem | Describe what’s wrong and why it matters | Clear problem statement |
| 2. Identify Contradictions | Determine conflicting parameters | Technical contradiction list |
| 3. Define the Ideal Final Result | Describe the perfect outcome | IFR statement |
| 4. Use the Contradiction Matrix | Find relevant inventive principles | Set of possible principles |
| 5. Generate Solutions | Brainstorm ideas guided by TRIZ principles | List of potential solutions |
| 6. Evaluate and Select | Assess feasibility and impact | Chosen solution for implementation |
This structure ensures that creativity is guided, not random.
Example: Reducing Machine Downtime
Let’s see TRIZ in action.
Problem: Frequent changeovers cause long downtimes on a coating line.
Goal: Reduce changeover time without increasing defect rate.
Step 1: Define the Contradiction
- Improving parameter: Changeover speed
- Worsening parameter: Product quality
Step 2: Consult Contradiction Matrix
The matrix recommends these inventive principles:
- Principle 10 – Preliminary Action
- Principle 15 – Dynamics
- Principle 28 – Mechanics Substitution
Step 3: Apply Principles
- Preliminary Action: Pre-stage materials and tools before shutdown.
- Dynamics: Use quick-adjust fixtures that adapt to product size.
- Mechanics Substitution: Replace manual alignment with a vision-guided system.
Step 4: Select and Implement
Combine these ideas to create a semi-automated changeover process that reduces downtime by 50% while maintaining quality.
This approach delivers measurable improvement without traditional compromises.
TRIZ vs. Traditional Brainstorming
Many Lean Six Sigma teams rely on brainstorming to generate ideas. While brainstorming encourages participation, it can lack direction.
Here’s how TRIZ compares:
| Aspect | Brainstorming | TRIZ |
|---|---|---|
| Approach | Free-form idea generation | Structured, principle-based |
| Consistency | Variable by team | Repeatable and systematic |
| Bias | Influenced by experience | Based on proven innovation patterns |
| Creativity | Broad but unfocused | Targeted and guided |
| Outcome | Many ideas, few actionable | Fewer but higher-quality ideas |
TRIZ complements brainstorming by bringing method to creativity. You can use both together—first use TRIZ to define directions, then brainstorm within those themes.
The 39 Engineering Parameters
TRIZ identifies 39 technical parameters that commonly appear in contradictions. These parameters describe the system’s characteristics. Examples include:
- Weight of moving object
- Speed
- Accuracy
- Reliability
- Cost
- Complexity
- Productivity
- Energy use
When two parameters conflict, you can use the Contradiction Matrix to identify which inventive principles apply.
This structured vocabulary ensures that teams analyze problems consistently.
ARIZ: The Algorithm of Inventive Problem Solving
For more complex issues, TRIZ offers ARIZ — a step-by-step algorithm. ARIZ combines all TRIZ tools into one structured procedure.
The general flow looks like this:
- Define the problem precisely.
- Identify contradictions and core conflicts.
- Define the Ideal Final Result.
- Analyze available resources.
- Apply TRIZ principles and knowledge bases.
- Evaluate potential solutions.
- Test and refine the best ideas.
ARIZ encourages deep analysis and ensures that creative thinking aligns with system constraints.
Trends of Technological Evolution
Altshuller observed that technologies evolve through predictable stages. TRIZ outlines eight major trends of evolution that help forecast future improvements.
| Trend | Description | Example |
|---|---|---|
| 1. Increasing Idealness | Systems deliver more benefits with fewer drawbacks | Automation replacing manual checks |
| 2. Dynamization | Systems become more flexible | Adjustable tooling |
| 3. Segmentation | Systems break into modular components | Work cells replacing monolithic lines |
| 4. Increasing Controllability | Systems allow more precise control | Real-time process feedback loops |
| 5. Transition to Micro-level | Functions shift to smaller scales | Nanocoatings, micro-sensors |
| 6. Substance-Field Evolution | Physical effects replace mechanical | Laser marking replacing engraving |
| 7. Integration of Sensing | Systems gain self-diagnosis | Predictive maintenance sensors |
| 8. Simplification | Systems achieve more with less | Fewer steps or components |
These trends help teams predict where improvement opportunities lie next.
Using TRIZ in Six Sigma Projects
TRIZ fits naturally into the DMAIC framework. It can strengthen the Improve and Design phases by generating innovative solutions beyond standard methods.
| DMAIC Phase | TRIZ Contribution |
|---|---|
| Define | Clarify contradictions in project goals |
| Measure | Identify parameters influencing performance |
| Analyze | Use function analysis to map causes |
| Improve | Apply inventive principles and IFR |
| Control | Implement self-monitoring or self-correcting ideas |
By integrating TRIZ, teams expand their problem-solving toolkit and achieve higher innovation yield.
Example: Eliminating Bottlenecks in Assembly
A team faced recurring bottlenecks in a manual assembly process. The goal was to increase throughput without adding labor.
Contradiction: Improving speed worsens workload and quality.
Using TRIZ:
- Principle 25 (Self-service): Let parts align themselves using gravity chutes.
- Principle 2 (Taking Out): Remove unnecessary manual checks.
- Principle 28 (Mechanics Substitution): Replace visual inspection with sensors.
The team implemented a sensor-guided assembly jig that reduced manual handling and improved throughput by 40%.
This success demonstrated how TRIZ drives creative yet practical process changes.
Common Misconceptions About TRIZ
Despite its power, TRIZ is often misunderstood. Let’s clarify a few myths:
| Misconception | Reality |
|---|---|
| TRIZ is only for engineers | It works for any process, including service and administration |
| TRIZ requires deep technical knowledge | Basic understanding of system behavior is enough |
| TRIZ replaces creativity | It guides creativity, not replaces it |
| TRIZ is too complex | You can start small with just the 40 principles and Contradiction Matrix |
| TRIZ only applies to design problems | It’s equally useful for operational improvement |
In fact, many service organizations now use TRIZ to innovate customer experiences and workflows.
