TRIZ - Theory of inventive problem solving

TRIZ, which stands for "Teoriya Resheniya Izobretatelskikh Zadach" in Russian (Theory of Inventive Problem Solving in English), is a systematic approach to problem solving and innovation that was developed in the Soviet Union by Genrich Altshuller and his colleagues in the mid-20th century. TRIZ is designed to help individuals and teams generate creative solutions to complex problems by leveraging patterns and principles that have been identified through the analysis of thousands of patents and innovations.

Key concepts and principles of TRIZ include:

1. **Contradictions:** TRIZ recognizes that many problems arise from inherent contradictions in systems. These contradictions involve conflicts between two or more desirable attributes of a system (e.g., cost vs. performance, weight vs. strength). TRIZ provides methods for resolving these contradictions to find inventive solutions.

2. **Inventive Principles:** TRIZ offers a set of 40 inventive principles that are used to guide creative problem solving. These principles provide general strategies for resolving contradictions and generating innovative ideas. For example, one principle is "Segmentation," which involves dividing an object into smaller parts.

3. **Patterns of Evolution:** TRIZ identifies patterns of how technical systems evolve over time to overcome challenges and improve functionality. Understanding these patterns can help innovators predict future trends and develop solutions that align with the trajectory of technological development.

4. **Ideal Final Result:** TRIZ encourages practitioners to envision an "Ideal Final Result" where all contradictions are resolved and the system operates perfectly. This can help guide the ideation process toward innovative solutions that move closer to this ideal state.

5. **Resources and Trends of Evolution:** TRIZ emphasizes the importance of understanding available resources, both technological and otherwise. By leveraging existing resources and identifying emerging trends, inventors can create more effective solutions.

6. **Function-Attribute-Object (FAO) Analysis:** This technique involves breaking down a problem into its functions, attributes, and objects, helping to uncover underlying contradictions and opportunities for innovation.

7. **Su-Field Analysis:** This analysis method focuses on identifying the relationships between components in a system and the physical or functional effects that occur between them. It helps to pinpoint potential areas for improvement or innovation.

8. **ARIZ (Algorithm of Inventive Problem Solving):** ARIZ is a structured process within TRIZ that guides inventors through various steps to systematically identify and solve problems. It provides a structured framework for applying TRIZ principles to specific challenges.

TRIZ is often used in engineering, product design, and innovation contexts to overcome technical and design-related challenges. Its systematic approach to problem solving and its emphasis on identifying and resolving contradictions have led to its adoption in various industries worldwide. While TRIZ has its roots in engineering and technical domains, its principles can also be applied to other areas where creative problem solving and innovation are needed.

Job to be done Framework

 The "Jobs to Be Done" (JTBD) framework is a concept in marketing and product development that focuses on understanding the underlying reasons why customers "hire" a product or service to fulfill a specific job or achieve a particular goal. Rather than just looking at product features or demographics, the JTBD framework delves into the functional, emotional, and social aspects of why customers make certain choices. The key idea behind the Jobs to Be Done framework is that customers "hire" products or services to get a job done in their lives. This job might not be a literal task; it can represent a functional need, an emotional desire, or a social requirement. By understanding the jobs that customers are trying to accomplish, companies can design products and services that more effectively meet those needs. Here are the main components of the Jobs to Be Done framework: 1. **Job:** The core focus is on identifying the specific job that customers are trying ...

Zwicky Diagram

 The Zwicky box, also known as the "morphological box" or "morphological matrix," is a systematic tool developed by the Swiss engineer and inventor Fritz Zwicky. It is designed to aid in structured problem-solving and idea generation by organizing a set of attributes or parameters into a matrix format. The Zwicky box is particularly useful for exploring various combinations of attributes to create new concepts or solutions. Here's how the Zwicky box works: 1. **Define Attributes:** Identify a set of relevant attributes or parameters that are relevant to the problem or challenge you're trying to address. These attributes should capture different aspects of the problem space. 2. **Create a Matrix:** Create a matrix with rows and columns corresponding to the attributes you've identified. The intersections of rows and columns form cells where you'll explore combinations of attribute values. 3. **Fill in the Matrix:** Begin by systematically populating th...

Ishikawa Diagram

 An Ishikawa diagram, also known as a fishbone diagram or cause-and-effect diagram, is a visual tool used to systematically identify and analyze the potential causes of a specific problem or issue. The diagram is named after Kaoru Ishikawa, a Japanese quality control expert who popularized its use as a quality management and problem-solving technique. The Ishikawa diagram resembles the shape of a fishbone, with the "head" representing the problem or effect being analyzed and the "bones" branching out to represent different categories of potential causes. It's a structured way to explore the multiple factors that contribute to a particular problem. Here's how to create an Ishikawa diagram: 1. **Define the Problem:** Clearly define the problem or effect that you want to analyze. This will serve as the "head" of the fishbone. 2. **Identify Categories:** Identify the major categories or groups of factors that could potentially contribute to the problem...
