Abstract: The non-certain choice and parallel pattern is ubiquitous in the real business practices，the execution pattern is chosen based on case character and run-time environment，which can be parallel，exclusive or interleaved executive pattern，but it is hard to be realized directly and effectively in many situations which makes it seldom be supported.In nature，the method of process modeling based on synchronize-manager separates the process management tasks from its execution tasks，defines the stable and variable parts of the process；this helps in flexible constructing of the model.Different management actions and model structure resemble can be used to create the non-certain choice and parallel pattern.Analysis of real cases shows that it is easy to construct the non-certain choice and parallel pattern by using synchronize-management，semantic description is more accurate，model is simpler and more effective and with better ubiquitous.

Key words: synchronize－manager, non-certain choice and parallel pattern, workflow pattern
