Theory of Inventive Problem Solving (TRIZ) 283

Principle 35. Parameter Changes
A. Change an object’s physical state (e.g., to a gas, liquid, or solid).

Based on principle 35A, the following approaches can be proposed for the
product development situation:

8. Use more virtual prototypes and computer simulation.

Principle 1. Segmentation
A. Divide an object into independent parts.
B. Make an object easy to disassemble.
Based on principle 1A and B, the following approaches can be proposed for the
product development situation:
9. Reduce the dependencies among subsystems of the product.
10. Promote modular design practices.

Principle 29. Fluidity
Make solid things into fluid things.
Based on principle 29, the following approaches can be proposed for the
product development situation:
11. Use a flexible organizational structure for the product development team,
and adjust team structures as the product development goes through
different stages.

In summary, by using the 40 inventive business principles, the following 11
suggestions are proposed to reduce product development time and cost:
1. Develop similar components and subsystems in parallel.
2. Develop noninterfering components or subsystems in parallel.
3. Simplify parts and reduce the part count.
4. Rehire retired workers for jobs where their experience is needed.
5. Borrow temporarily underutilized workers from other organizations.
6. Prepare preliminary works on key development activities long before these
activities’ starting times.
7. Break down barriers between departments and form a fully empowered
product development team.
8. Use more virtual prototypes and computer simulation.
9. Reduce the dependencies among subsystems of the product.
10. Promote modular design practices.
11. Use a flexible organizational structure for the product development team,
and adjust team and structures as the product development goes through
different stages.
