Lean manufacturing tool series -14 (Workflow diagram)

Workflow diagram – An important lean tool

They say that a picture is worth a thousand words. In the case of business and process management, this couldn‟t be any more true. When it comes time to lean out a process, system, or business, the question of visualizing the process always comes up. Luckily a tool exists to bring everyone on the same page as well as visualize the processes involved, and this tool is a Workflow diagram. A workflow diagram is like the secret decoder ring that will result in the team‟s understanding and focused improvement.


Just as it sounds, a workflow diagram is a visual depiction of a workflow, using visual representations such as flowchart symbols and annotations to show the different steps and decision points in a workflow. A workflow is a sequence of operations or processes as defined by the work of a person, a machine, a group of machines, or a group of people, organization or staff. The work itself may actually be a virtual representation of actual work, such as a decision, processing of a document, or a procedure that is conducted. The flow part of the workflow is oftentimes depicting a transfer of a document or piece of a product from one step or workstation to another.
The workflow itself is not a great lean tool. While depicting the process helps to visualize what is happening inside of the company, it does not show the places for improvement. Like a roadmap, it maps out the different destinations and paths to get to and from a destination. Also like a map, it does not show where the roadblocks, bumpy roads, heavy traffic, or bad weather is. Just as a map can be used as an underlay for a weather map or traffic map, the workflow can be used as the building block on which other assessment tools are based.
The workflow can be used as a great learning tool, especially for newcomers to the organization, which is an ISO requirement.
In reality, it is often hard to trace the exact path of a task or document, especially when functional tasks and operational teams are not clearly defined. The workflow will often be better represented by a series of intertwined webs instead of clearly defined paths and flowing roadmaps. It is very common for a company to employ the use of software to help in defining and managing the workflows associated with a company.
After it is defined and improved, the end result is usually a better overall understanding of the company‟s processes as well as improved efficiency, less complicated processes, improved process control and better quality and standardization. If all of the members of a workflow and business understand where their place is in the workflow and how they are supposed to interact with other teams and organizations inside of the workflow, the results are sometimes amazing at the level of improvement that is possible. When a company first decides that it wants to employ lean processes, they usually start with a workflow diagram. Most managers and company executives are shocked to find out the inefficiencies that occur inside of their organizations. It is also a great way to make a big difference quickly by reminding, or informing all personnel that operate inside the workflow of what they should be doing with respect to processing the documents or materials that they handle.
