From the traditional point of view, solution contains only scheme generation stage, specific implementation stage is divided into another.

But from the unification process perspective, solution directly for operational level service, they are not simple linear relationship and a single interface. So, in a sense, solutions and implementation are mutual interaction, the execution effect should be timely feedback, and to the original plan to make correction of reference and suggestion.

This kind of interaction is multiple, repetitive. A continuous self improvement solutions, can really improve the situation, making it more efficient implementation.

On the contrary, some complicated real case, the problem involves more elements, the problem have complex link. If you expect to a perfect solution, one-time solve all problems. Proposed scheme can rest easy, on the actual progress of challenges. In the actual seems to be not too realistic, can also cause does not adapt the effect.

In market economy, especially for customer's case, can provide reference implementation, even can personally involved in the implementation of the specific solutions, it is more likely to be agreed with the customer and popular. Jane and
