Question:

We tend to think of flow charting in terms of improving or documenting an existing process, but can a flowchart also be useful for new processes. Why? How? I believe I saw an example or two earlier in the discussion this week.
Can you think of other examples that you may be familiar with that involved creating a flow chart to develop a "new" process or procedure?
