Lean Manufacturing Implementation for anyone ...anywhere ...anytime.

It takes more than systems sophistication for manufacturing companies to gain control of factory operations. To achieve on-time shipments at healthy profit margins, companies need to continuously improve obsolete MRPII/ERP shop order "launch and expedite" systems with the simplicity of sequential production. The assertion that sequential production only works in high production, widget-manufacturing environments is a myth. Leading low- volume, "make-to-order" manufacturers are improving schedule flexibility, customer responsiveness and profit margins by developing and implementing the Sequential Production Process. 

Henry Ford first introduced sequential production at his River Rouge operation in 1920. Using sequential production as a basis for his production line concept, the Ford plant was able to go from receipt of iron ore to casting the engine block, and to shipment of the machined engine block in a final 
assembled car in an astonishing forty-eight hours. Ford's success, however, was limited by a manufacturing philosophy that called for the absolute power of a management hierarchy.

Today the success of sequential production is in the hands of production workers and team dynamics. Product build/test operations content and sequencing, production tools and instructions, logistic layouts and cycle time targets are some of the responsibilities of the line worker in today's sequential production environments. The improvement of speed, quality, costs are all placed within the responsibility and control of the production worker through team dynamics.

Sequential production is neither an inventory control system, nor a replacement for MRP. It is an organized and focused assault on production flexibility, speed, quality and cost. It is a process that requires total employee involvement and participation in the continuous improvement of manufacturing performance. It focuses on cycle time reduction via reduced 
lot sizes and setup times, preventative maintenance, workplace integrity, visual scheduling and worker flexibility. Sequential production tools and techniques include process capabilities, reduced process variances, causal analyses with root cause determination and relevant corrective actions.

While starting a sequential production project at the end of the production process is good advice, one heavy equipment manufacturer started at the front because they could never start a customer's machine build on time as 
they always had to wait for the machine's welded base structure to be finished. The excuses for the delay: late shop order releases, raw materials shortages, no one told us to start, and it's a huge, complex, time consuming 
project. It was decided to break the machine structure build process into a six-station sequential production work cell: 1) raw materials prep, 2) sub- assembly welding, 3) frame welding, 4) tank build/installation, 5) manifold 
build/installation and 6) painting. The plan was to flow the work from one station to the next using visual scheduling and point-of-use logistics. 

To everyone's surprise and delight, not only did this new production process make life easier for the weld shop personnel, it increased productivity and improved quality and eventually even reduced inventories. But most important, customer lead-times were reduced because machines no longer had to wait for the welded base structure.

A good approach to Sequential Production Process implementation is first to train all workers in the continuous improvement process (kaizen) and team dynamics. Next is to select a logical pilot project that would be carried out 
in advance of the rest of the plant "rollout." The project should provide an area that can be isolated from material flows in the rest of the plant, but with production processes similar to the rest. The objective is to gain a quick success before "rollout" to convince the skeptics that it is the way to go.
