A common mistake is to make a good and effective change in a process, but leave aside the supported environment for long-term sustaining of the results. And often do we see past efforts go down hill and sometimes completely disappear. There is a flow of information toward the changed process that must be streamline, precise and accurate. This information flow must be adapted the new reality of the changed process, otherwise sustaining will be weak and eventually falls. There are tools, lean tools, for information stream flow.
