Systematic Problem Solving Technology Evolution S-curve
Every technology evolutes in S-curve. Technology transfer is inevitable to reach higher degree.
Focus of invention is dependent on S-curve position.
To minimize cost
To increase reliability
To increase efficiency
To increase performance
To operate stably
To be operable
