One of the most powerful lean tools is called value stream mapping, a visual management method used to document the flow and creation of value in a process. The definition of a value stream is all steps—both value-added and nonvalue-added—that contribute to taking the process from raw materials to the customer. Value stream mapping can be used to understand and document the production floor, in-office processes, hospital surgical wards, and even at home.

The first step in value stream mapping is to choose the process you want to improve, which will then be mapped. I recommend starting with a small, easily defined process before tackling something more complex. For example, instead of trying to map an entire manufacturing operation, start with a specific work cell or operation. In an office environment, start with the accounts payable process instead of the entire financial management process. Sometimes, especially early on in a lean transformation, it can be difficult to identify specific processes. I’ve seen way too many organizations take their first steps into value stream mapping by trying to map their entire organization. This generally results in mass confusion, disappointment, and walls covered with sticky notes.
