Waste is “a deviation from the way things ought to be” – which in our terminology is a “problem.” One type of waste is material waste. In manufacturing this includes defective or useless material produced by the manufacturing process. In service areas any duplication of effort or information collected is waste. Another type of waste is rework, when a product or service must be redone (including time and money spent correcting errors, unacceptable work and misinformation.)
Material waste and rework are often easily observable. These can be targeted for action by listing them, as problems, directly on a BPI Problem Inventory (or Concern Analysis) worksheet. But, another type of waste is hidden within normal operations or “the way we do things.” It is process waste and includes extra steps and inefficiencies that have been built into the work process itself.
Reveal process waste
State the purpose specifically, indicating the direct customers and what product/service is provided to them.
Work flow chart
Chart how work comes into the unit and all the steps/activities taken by the department. Leave nothing out. List everything (e.g. inspecting, double checking, storing, moving from one place to another, returning telephone calls, making reports, etc..)
Each activity (above) either adds value – value-add, or doesn’t – non-value-add. Anything that produces the product or service directly is a value-add. If the activity does not directly produce the product or service it is a non-value-add (e.g. storage, inspecting, proof reading, transporting, walking, lifting, filing.)
Work flow deviations
All non-value-adds are targeted as deviations to be listed on a Problem Inventory work sheet. Remember “storing” or “waiting” are non-value-added activities. So, don’t overlook work flow pinch points – those places where work stacks up because it can’t handle the amount of work being pushed through the system. You should also be aware of value-adds that take too long. These should be listed with the non-value-adds as deviations on the Problem Inventory list.
Effort spent producing goods or services that the customer doesn’t want are another source of waste. So, a real effort should be made to understand what is needed from the point of view of the customer. This is not a one-time activity. Make sure the unit has a procedure that includes the customers in the problem identification loop. Also, enlist the help of suppliers. There may be procedures that interfere with their ability to meet what the unit needs.
Outside the unit
Waste that does not directly affect the unit or its customers should also be identified. It takes work to produce anything, including waste. Finding places where efforts are being wasted provides valuable feedback to the organization.
Sources of work complications
Work processes become complicated and inefficient when decision-makers use “muddled action” (trial and error) instead of “corrective action” (addressing the root cause). To maintain and improve processes, decisions should only be made when the true causes of problems are known. Also, be aware that “interim actions” create work complications. They should only be allowed to exist for a brief period of time – just long enough that the cause of a problem can be verified and effective corrective action implemented.
Critical thinking collaboration
The “Targeting Waste” procedure outlined in this article is a good place to start to clean up the debris of past decisions. In the long run, using critical thinking tools to uncover root causes and to select the best corrective actions will help prevent new work complications. This is the surest way to fine tune technical and human systems for continuous improvement, day-in and day-out.
This may sound like a lot of effort. But on the other hand, how much waste can your organization afford? Let us show you how to minimize the effort required to eliminate the waste in your processes. Contact BPI for information on how our Critical Thinking workshops can provide the knowledge, skill and procedures to make “targeting waste” in your organization a money-saving, permanent way of operating.
