A workflow is a flow of work carried out in parallel and in series by people. In order to improve efficiency, it is required to change the current workflow dynamically. Since dynamic change of workflows may probably make the series of work inconsistent, it is necessary to find out consistent change of workflow. As consistent ways, three types of dynamic changes: flush, abort, and synthetic cut-over (SCO), have been proposed. However, the concrete analysis and evaluation have not been done. To do the performance evaluation for the dynamic workflow changes, comparison of the times (called change time) cost in the individual change and the methods how to obtain such times become ever important. In this paper, we first give a definition of change time and then propose the computation methods individually for each change type. Finally, we do experiments to evaluate the performance of three changes by doing the comparison of the change times.
