Introduction

This book can be divided to three parts: problem solving by analyzing contradictions, the development of systems without direct use of contradiction analysis and the implementation of TRIZ for achieving business objectives. Chapters 2 7 covered the first part:

• Contradiction

• Resources

• The ideal final result

In this short chapter, we reach the midpoint.

Chapters 9 10 contain the second set of concepts and tools:

• Patterns of evolution

• Forty principles of innovation

Chapters 13 15 address the implementation of TRIZ in organizations.

• How to implement TRIZ, the use of TRIZ with various other tools

• Using TRIZ together with the Theory of Constraints (TOC)

• Using TRIZ together with Six Sigma

Figure 8.1 shows a review of the three basic concepts studied so far. It is a more detailed presentation of Figure 7.1.

Figure 8.1: The cycle of TRIZ. The three upper boxes present three basic concepts. The lowest box shows the reformulation of contradictions. The loop shows that the problem-solving process is repeated. In practical situations, it is not unusual to go around the loop four or more times. You are making progress if you are answering different questions each time.

After the review, we present a general agenda for a problem-solving session. This is a one-page summary of the instructions given in previous chapters, which is illustrated with two familiar cases: lawnmower-noise muffling and carrot cultivation (Tables 8.1 and 8.2).
