Avoiding a Common Manufacturing Problem

Otis Elevator’s costly move of its Mexican plant to its South Carolina plant is a common problem in manufacturing. Sadly it is an elementary, “Manufacturing 101”, process that seasoned manufacturing managers know how to avoid.

Contrary to Otis’ reasoning that “…it was trying to do too much”. The principal cause was most likely that the “manufacturing fundamentals” were not accurate.

This would include inaccurate bills of material and routings in its cost system:

Bills of Material not accurate:

When the daily production plan is published and individual product (SKU) orders are released to the plant floor component parts are taken from inventory and sent to the production floor. If the bills of material for the SKUs are not accurate, some of the parts necessary to produce the product will be missing resulting in production delays. As a result, hourly production employees are idled incurring costly labor variances.

Inaccurate bills of material complicate an operation further because supply chain does not know what component parts to purchase to support sales and production. Supply chain uses the bills of material and sales forecast to decide what raw materials to purchase.

When moving production to a different plant, if the bills of material are not accurate, the necessary component parts to produce a product will not be transferred or on-hand at the new plant.

Not everything may have been captured in the older, long-used manufacturing plant’s bills of material. There may be an informal system in-place which long-term employees know from experience what parts are needed to produce a product – although these parts are not included in a cost system’s bill of material.

Routings incomplete:

Routings are simply the timed steps a product (SKU) takes from start to finish in the production cycle. It is possible that the older plant’s routings were not accurate. But experienced employees may know how to successfully route product through production.

However, if routings are not completely accurate when a plant is moved, it will be virtually impossible for the new plant’s management and engineers to establish the correct order of steps and tasks to produce product.

It would be the same as when we assemble a new bicycle for one of our children. We open the box and find only a completely disassembled bicycle – only parts. But there are no instructions included on how to assemble the bicycle. We may eventually figure out how to put the bike together, but it will take a longer time with hits and misses.

It is not much different asking production managers and engineers to produce product with inaccurate routings.

Once a cost system is in-place it is fairly easy to maintain it daily by manufacturing and industrial engineering and cost accounting allowing supply chain to maintain the requisite inventory supported by a bar coding system.

Reason I wrote my book “Learn to Whisper”

The reason I wrote “Learn to Whisper”:

My conclusion after operating as a Turnaround Chief Executive Officer for more than twenty-five years is that the majority of this country’s top management is far from first-rate. In fact top management, particularly at the chief executive officer level, is at best average with a large number that can be rated mediocre. This lack of management competence has seen this country’s market leaders lose sizeable market share to foreign manufacturers able to export better quality and lower cost products to the USA. It has seen manufacturing and service operations unnecessarily moved to foreign countries. All of which has negatively affected the economy, severely damaged former blue-chip corporations and seen quality jobs lost.

It is quite common to discover that companies struggling with this inability to compete with foreign companies have been simply mismanaged. The once successful business deteriorated because of an incompetent chief executive officer and weak senior management

Why doesn’t this nation have first-rate management? Inadequate training. Chief executive officers and vice presidents learn “on the job”. A number get promoted based on personality, political connections and drive – not merit. They are not carefully screened for the potential to become successful at managing. For some all that is needed is a well-written resume, the right interviewing style and the inability of a new employer to accurately assess skills, performance and potential.

Compare this to the process doctors go through. From medical school to internship to residency to a senior role after years of education, experience and continuous training their progress and capabilities are constantly monitored even after they become senior in the profession. Generals and Admirals go through a similar protocol. They must prove themselves in low-level assignments before they are judged qualified for senior positions. Unqualified applicants in both professions are culled out. What can be done to improve management competence? Education, on-the-job training and job performance monitoring. My book will educate people on the subject of managing. Its 101 management lessons are separated into the 17 subjects managers need to know.
