Number of People

We often include the number of people who currently perform the work described on the Post-it. This data is especially helpful if, during future state design, the team sees the need for work balancing or designating resources to a specific value stream. The number of staff can also point to two other potential problems. If staffing is too low to accommodate the volume of incoming work, work will stop flowing. On the other hand, if the staff performing work is very large, it’s a good bet that there’s high variation in how the work is currently being done and that adopting standard work down the road will require greater planning and follow-up.

In some cases, it’s relevant to include not only how many people regularly do the work, but how many are trained and capable of doing the work. You may also want to record the number of people if there is insufficient backup to cover vacations, staff vacancies, and so on. As you’ll see in Figure 3.6, the classic value stream mapping symbol for the number of people is a circle with a curved line under it (which represents an aerial view of a person sitting in a chair). We don’t include the number of people who do the work if staffing is already known to not be a significant factor in value stream performance.
