Over the last few years there has been a lot of talk about reshoring and bringing manufacturing back to the USA. We should take a look at what manufacturing really is, if and when it is coming back to the USA.
Recently even, the A.T. Kearney Reshoring Manufacturing Index has shown that although there is reshoring optimism and we all have hopes of bringing more manufacturing back home versus offshoring manufacturing to other countries, that reshoring is still not outpacing offshoring.
But regardless of whether reshoring is increasing or not, we are still seeing world class manufacturing companies reshore their operations back to the United States. You can always view the most up to date list of at The Reshoring Institute‘s website here. And further, what we must continue to focus on are the fundamentals and the basic understandings of what is manufacturing and how we can create excellence in operations in order to create a prosperous economy here in America.
I’m fortunate to have been employed at some “World Class” manufacturing and assembly companies:
• Schwinn Bicycle Company: Chicago, IL: Schwinn manufactured their frames, forks, and small parts for their bicycles, but was mainly an assembly operation. The majority of parts were purchased domestically, and internationally (many parts purchased internationally were not made in the USA at that time.)
• General Binding Corporation (GBC), Northbrook, IL: Manufactured “Cerlox” plastic bindings for the end of note books. Plastics were purchased and stored in huge silos. GBC manufactured and assembled shredders, and equipment to encapsulate paper documents in plastic.
• Troy-Bilt: Troy, New York: Manufactured and assembled various sizes of roto-tillers called: “Horse”, “Pony”, etc. They supplied tractors and trailers to the farm industry.
• Jovan Cosmetics: Bensenville, IL: “Musk” Cologne, Ladies Cologne, Beecham Cosmetics, Underarm Deodorant, and Cassini Products along with other special cosmetics.
A manufacturing business is any business that uses components, parts or raw materials to make a finished good. These finished goods can be sold directly to consumers or to other manufacturing businesses that use them for making a different product. These manufacturers are called Subcontractors. Manufacturing businesses in today’s world are normally comprised of machines, robots, computers and humans that all work in a specific manner to create an end product.
Manufacturing plants often use an assembly line, which is a process where a product is put together in sequence from one work station, work center or cellular manufacturing center to the next. By moving the product down an assembly line, the finished good can be put together quicker with less manual labor. It’s important to note that some industries refer to the manufacturing process as fabrication.
Manufacturing businesses can be very simple, with only a few parts required for assembly, or they can be very complicated, with hundreds of parts needed to create a finished product. A Bill of Material lists all these various parts in levels, as they should be assembled or manufactured. Compared to other businesses, manufacturing businesses usually have more legal regulations and environmental laws to deal with, if they don’t they can be fined. These things can range from scrutinized labor laws to safety (OSHA) for employees, to environmental and pollution issues. Although labor unions are not as common as they were 50 years ago, they still heavily exist in the manufacturing industry, where wages, benefits and other rights are negotiated.
Four simple questions help to define manufacturing, as Ollie Wight said many years ago, they are:
Simply we can offer the following answers:
The MPS is exploded and reads the BOM and Inventory on hand to create make (manufactured) and buy (purchased) components needed to fulfill the MPS. Obviously accuracy of the BOM and Inventory are critical, and the goal should be 100% daily. Since there is no perfection, 98-99% accuracy is considered close enough to the goal of 100% accuracy. The ‘ole “garbage in; garbage out” (GIGO) adage definitely applies here.
Schwinn: All of this was done manually, by hand, responsibility: the Inventory Manager. It was called, “The Short List”. Why? This showed Purchasing what was “short” and needed for production (MPS) in what month. Purchasing would review this list, in their particular area of parts responsibility (by commodity) and Purchasing would send hand-written notes to the Inventory Manager on the status of the “short” parts. For any new purchases a red Traveling Requisition (TR) was used.
GBC: Initially, Production Planning would issue Traveling Requisitions (TRs) to Purchasing with offsetting lead times and a “Due Date” to meet the MPS. An ERP system was eventually put in, and did all of these calculations automatically. But, the accuracies of near 100% daily were absolutely needed to meet the MPS.
Troy-Bilt: TRs were used. But, Production Control used Vendor Scheduling to meet production plans and to manage inventory. Purchasing was tasked with Cost Reduction, Sourcing and Purchase Orders.
Jovan Cosmetics: Basic MRP as shown above. All MRP sheets were given to Purchasing to manage. These were Purchasing’s “Requisitions.” Inventory was not accurate and either were the BOMs, so GIGO. Purchasing was always in trouble and “behind the eight ball.”
What were your experiences in the past, “good ‘ole days of manufacturing that you would share? What is manufacturing in your opinion and how would you expand upon the questions posted above? Let me know in the comments section and stay with me tomorrow for what I explain is the most important part of what is manufacturing and how excellence in manufacturing operations is achieved.
