Expanded information

The characteristics of the new QC seven techniques:

1, organizing language The tool of information?

2, the method of graphical representation of linguistic intelligence?

3, trigger thinking, effective solution to the messy problem;

4, enrich the plan;

5, to prevent omissions, negligence;

6, so that the people concerned to understand;

7, to promote the assistance of the people concerned;

8, really express the process.

9, management tools, can be applied to areas other than QC

Five benefits of the new QC seven practices:

1, quickly grasp the focus - real-time grasp of the center of gravity of the problem, not like a fly on the wall can not find the focus.

2. Learning to emphasize planning - effectively analyze the problem and seek solutions through the use of techniques.

3. Emphasize the process of solving problems - the process of solving problems, not just the results.

4, understand the focus of the goal - have the right direction, will not lose sight of the other.

5, the whole system-oriented - to strengthen the importance of full participation, and then produce a sense of participation and identity.
