I have been charged with completing a VSM for an IT maintenance process that actually will have 4 paths that occur in parallel. Can you complete on VSM or do you actually have 4 separate?0July 26, 2006 at 3:37 pm #58843
One can do four parallel paths, but it does get messy in the classic VSM style. If there is one or more paths that are relatively irrelevant to your improvement need, then it may be OK to simply omit them. If there are all important, then I offset them slightly to allow the timeline to show them. The critical path is the longest time of the paths and is a good place to focus.
Another way of showing parallel path processes is to use a vertical VSM template that allows columns to show the v and nv times by step. This method is useful when there are numerous interactions within a process flow such as interacting with a customer and/or supplier to the process.
The key is know what metric is important to your improvement goal and simplify your map to focus on the important contributing areas of your process. Keep it simple.
Hope this helps.0
