“You get what you measure” is an old saying but is never far from the truth.  The old paradigm measurements led us to do the things in the shop and in the warehouse that were the antithesis of lean manufacturing and supply management.  So, if you are talking lean and are trying to influence shop floor people to implement lean, then you have to measure what is done in lean terms so that the message is clear.

To test the “get what you measure” axiom, just try putting up a chart of a particular measurement statistic showing performance over time in a place in a place where plant people (particularly managers) are likely to see it.  Questions will be asked and soon, behavior will begin to reflect the desired direction of the numbers.  When the New York City Police Department senior management began a program of measuring crime statistics by precinct (known in the NYPD as “COMPSTAT”) and asked the commanders to explain the unfavorable trends, crime declined in the city.  Similarly, corporate senior management measures activity, much of it, like overhead absorption, unrelated to lean manufacturing leading to non-lean results.  So to get going in the right direction, let’s look at some desirable lean metrics.

OK, the title sounds facetious.  But we are, in fact, schizophrenic about the state of manufacturing in the United States.  It seems like all the familiar products we buy from the expanded pharmacy to the big box stores come from developing countries in Asia and Latin America so we think that manufacturing has left the country never to return.  Yet lately, we hear reports of a “rebirth” of manufacturing based on anecdotes about one or another company’s decision to relocate a plant back home and opinion surveys.  The press also reports that “manufacturing is leading the recovery.”   Small wonder that there is confusion!

Cellular Organization 
Who Invented Lean?

By Gerald Najarian

Here’s a question for you:  who created the first cellular factory?  Hint – it was an automobile company.  We’ll come back to the answer later in the article but first let’s look at cellular organization in the lean factory.

Why organize in cells?  In a lean factory, cells, in fact, create little factories within the big factory (not exactly like the fad a few years back called “factory within a factory,” but similar) that allow a mixed model product line to be manufactured as an island by itself.  Cells, when organized and balanced properly, permit product to “flow” in one piece production from the first part to the final product without stopping to become a subassembly so there is no WIP inventory between the work stations in a cell.

Traditional accounting measures are out-of-date-established more than a century ago when customers were content, not demanding, and when inventory was seen as beneficial. It’s time to recognize lean manufacturing concepts in accounting practices. Join Gerald Najarian as he explores how certain methodologies and concepts, held dear by many, must be re-examined in order for accounting to be effective in a lean operation.

 A materials planner identifies the need for a particular component part, prepares a requisition. The buyer surveys at least three vendors, selects one based on the economics (price) and issues a purchase order for delivery in thirty days. The vendor, new to the company or accustomed to sporadic demand for the item from this customer, forces the item into the schedule and begins the process of sourcing needed materials. When the item is finally produced late and isn’t delivered to the door of the customer’s plant as expected, the phone starts ringing with expedite requests. At last the item arrives at the plant and is received, inspected to pass an AQL standard, and stored in a parts stores area. There it awaits requisitioning to a shop order that has been delayed due to unavailability of the part. Sound familiar?

Right-Sizing Your Labor Cost Infrastructure

A rediscovery of industrial engineering

By Gerald Najarian

Did you know that the exemplar of lean manufacturing, Toyota, assigns an industrial engineer to each foreman in its plants?  It’s true.  Toyota has long understood the value of optimizing operations through traditional industrial engineering techniques.  For example, the company “stopwatches” each operation to assure that the people performing work tasks can actually accomplish the task in an optimal amount of time.  Optimal is defined as the rate feasible to do the task “right the first time” according to the Toyota standard method (for quality purposes) and to be economically efficient in the traditional manufacturing cost paradigm.  If the time assigned to an operation is not “optimal,” then the workers receive additional training or the operation time is adjusted.  Assigning an industrial engineer to each foreman has other benefits – work flow management, cycle time reduction, work methods and the like.

Step Up to Lean
Achieve the benefits of lean, one step at a time.
By Gerald Najarian

There is no question that lean and its antecedents—Just-in-Time (JIT), flow, and demand-based manufacturing—contribute mightily to a company’s ability to deliver outstanding customer service while tying up a minimum of working capital principally in the form of inventories. The attributes of well-managed manufacturing shops have been gathered under the broad heading of lean and have been given programmatic status.

Well, we are ten years into the new  millennium and well into the age of the supply chain. We successfully survived the Y2K non-crisis and, in the process, have gotten a new enterprise resource system (ERP) to support the company’s information management infrastructure. Now, in the age of supply chain management, we are trying to tie all the nodes of the supply chain together so that materials flow seamlessly along a path beginning with a customer’s order and pulling through from the raw material supplier all the way through the process. All of this is good. The previous 20 years were turbulent ones for the manufacturing/materials executive as we absorbed the new disciplines of the period and saw the old ones disappear: ERP replaced Manufacturing Resource Planning (MRP) II, the Just-in-Time wave from the far east morphed into Demand-based Flow and then Lean, shop organization went from functional to product-based, and the multitudinous materials management functions began to creep together into a homogenous unit known as the supply chain.

Perhaps the most frequently heard question after the ones about setting up flow lines and how one-piece production results in greater output is: How do I get the cost accounting system to help me make the right decisions in a flow environment?

To get a good understanding of how we can get the right accounting information in the new world of flow, it is necessary to look back at the roots of manufacturing cost accounting, its evolution to the present and the relationship of accounting-to-manufacturing processes then and now. Above all, it is important to keep in mind the exhortation of Charles T. Horngren, one of the principal cost accounting thinkers in recent times, who suggested: “There are plenty of good ideas in both the old and the new. I anticipate a brisk evolution, not an earthshaking revolution.” We are unlikely to have an earthshaking revolution, for accounting managers like manufacturing managers embrace change slowly and usually only when they are convinced of the need for change. So let’s take the journey from our manufacturing legacy up to the present and relate cost accounting to the modern era of flow, constraints management, and infrastructure factories.

Observation of business success or potential failure has a long history in the realm of financial accounting. We are accustomed to being observed at the end of the month, quarter or year to ascertain success or failure only to realize that accounting data, while the final tally, serves a higher master and are inadequate for the observation that matters—day-to-day performance.

As a practical matter, inspection of operations and operating performance becomes increasingly more difficult as size and complexity grow. Manufacturing performance measures permit this form of inspection for management and are also a positive way to communicate the results of efforts in the management of work centers. In this respect, performance measurement is setting the atmosphere in which activities and processes are monitored as the means to accomplish positive financial results. Properly established, simple and understandable metrics create an environment of positive goal setting in which all know what is expected. (more…)
