Binary Process Analysis Accounting For Process Variability

摘要

Reducing process cycle time is focused on to improve business processes. Before incurring cost to reduce cycle time,estimates of benefits should be developed and used to define improvement plans. Benefit assessment are usually based on average cycle times for each step of a process. However this approach does not account for process variability. Nor does the approach account for unique situations like binary process events. A binary process event occurs when a decision with two possible outcomes occurs in a process. IN this work a method is excogitated,accounting for variability,to estimate process steps for their full range of variation and assess the impacts of binary events. When binary events are involved in a process,results from the analysis provide better evaluation cycle time variation than an average approach. Further more,the outputs can also be used to define the probability of exceeding a desired cycle time.
