  1. 1. TRIZ – Innovation Vishwanath Ramdas
  2. 2. Vishwanath Ramdas is … <ul><li>Visit him @ </li></ul><ul><ul><li> </li></ul></ul><ul><li>Process and Business Consultant </li></ul><ul><li>Working in areas like ITSM, Software development, process consulting … </li></ul><ul><li>Based in bangalore [India] </li></ul>
  3. 3. This presentation thanks <ul><li> </li></ul><ul><li> </li></ul>
  4. 4. Traditional Approach to innovation <ul><li>Within the scheme of things </li></ul><ul><li>Look at analogous solutions to the problem @ hand </li></ul><ul><li>The standard approaches are random and pshychological dependent on past experience </li></ul><ul><ul><li>Brain storming </li></ul></ul><ul><ul><li>Trial and error </li></ul></ul><ul><li>This leads to … </li></ul>
  5. 5. Psychologically constrained approach
  6. 6. Pshychological inertia. <ul><li>Defined as the inability to go beyond the current realm of knowledge ( within individual or group) </li></ul><ul><li>While most solutions are to be found out there!! </li></ul>
  7. 7. Pshychological inertia
  8. 8. Althsuller - TRIZ <ul><li>BASIC PRE-REQS </li></ul><ul><ul><li>be a systematic, step-by-step procedure </li></ul></ul><ul><ul><li>be a guide through a broad solution space to direct to the ideal solution </li></ul></ul><ul><ul><li>be repeatable and reliable and not dependent on psychological tools </li></ul></ul><ul><ul><li>be able to access the body of inventive knowledge </li></ul></ul><ul><ul><li>be able to add to the body of inventive knowledge </li></ul></ul><ul><ul><li>be familiar enough to inventors by following the general approach to problem solving in figure 1. </li></ul></ul>
  9. 9. Althsuller studied patents <ul><li>200,000 ( by now it is 1.4 MM) </li></ul><ul><ul><li>Found that only 40K where truly inventive </li></ul></ul><ul><ul><li>The remaining only straight forward improvements </li></ul></ul><ul><ul><li>He classified patents by approach and not subject matter to uncover the ideation process </li></ul></ul><ul><ul><li>He found that true innovation strieved to overcome “CONTRADICTIONS” </li></ul></ul><ul><ul><li>He also found that most inventions seemed to have similar patterns (40 of them!) </li></ul></ul>
  10. 10. He classified the inventions by their import! <ul><li>Level one. Routine design problems solved by methods well known within the specialty. No invention needed. About 32% of the solutions fell into this level. </li></ul><ul><li>Level two. Minor improvements to an existing system, by methods known within the industry. Usually with some compromise. About 45% of the solutions fell into this level. </li></ul><ul><li>Level three. Fundamental improvement to an existing system, by methods known outside the industry. Contradictions resolved. About 18% of the solutions fell into this category. </li></ul><ul><li>Level four. A new generation that uses a new principle to perform the primary functions of the system. Solution found more in science than in technology. About 4% of the solutions fell into this category. </li></ul><ul><li>Level five. A rare scientific discovery or pioneering invention of essentially a new system. About 1% of the solutions fell into this category. </li></ul>
  11. 11. The levels again! 90% of the solutions had been solved before! 1,000,000 All that is knowable 1% Discovery 5 100,000 Knowledge outside the industry 4% New concept 4 1000 Knowledge within the industry 18% Major improvement 3 100 Knowledge within company 45% Minor improvement 2 10 Personal knowledge 32% Apparent solution 1 # of solns. Source of knowledge % Degree of inventiveness Lvl Table 1. Levels of Inventiveness.
  12. 12. TRIZ – The Approach Step by baby step!
  13. 13. Law of increasing Ideality… <ul><li>Utility divided by Harmfulness </li></ul><ul><li>Harm >> cost, footprint, energy consumed, pollution, danger, etc </li></ul><ul><li>The faster you get there the more inventive you are! </li></ul><ul><li>The evolution of the mechanical spring-driven watch into the electronic quartz crystal watch is an example of moving towards ideality. </li></ul>
