The emerging theory of manufacturing. Harvard Business Review

The objective of
this article is to discuss the “post modern” factory. Drucker
discusses the new age of manufacturing and describes a conceptual model of a factory using four
principles that were developed separately. The principles are:
1) the use of Statistical
Quality Control to change the social organization of a factory,
2) the new concept of manufacturing accounting that allows
people to make
production decisions as business
decisions,
3) the use of “flotilla,” or module, organizations,
and finally,
4) the use of the systems approach to emphasize the
economic process of business.
Statistical Quality Control is a concept that was developed in the 1930’s and revised into its present form during World War II by W. Edwards Deming and Joseph Juran. Statistical quality control is a scientific method of identifying the quality and productivity that can be expected from a given production process. It can be used to quickly identify and locate malfunctions. It is also used to evaluate any positive or negative impact on performance related to changes made to the system. Finally, SQC is used in the continuous improvement process to identify where and how the process can be improved.
One of the aspects
of SQC is that it causes an increase in the number of machine operators. However, to make SQC work the machine operators are given more
empowerment. This causes a
reduction in the number of supervisory positions and leads to another benefit. The SQC process was able to combine the two basic approaches of
manufacturing, the engineering approach and human relations approach. The engineering approach called for zero defects without the involvement
of supervisors with the use of built-in process control. The human relations approach viewed the knowledge and effort of the line
workers as the best resource for controlling and improving quality and
productivity. SQC combined its
methodology with that of the engineering method. In doing so, it was able to effectively implement a more efficient form
of built-in process control. Empowerment, important to the human relations approach, was also provided by SQC.
SQC’s contributions to the human relations approach and engineering
method helped combine the two manufacturing approaches.
One of the new
concepts of manufacturing is the integration of manufacturing with business
strategy. Drucker described
manufacturing accounting as being the third leg of a manufacturing stool along
with scientific management and the assembly line.
The old cost accounting system ignored non-production activities, such as
quality control. The group that
initiated the change in manufacturing accounting was actually machine makers. The old system of manufacturing put too much emphasis on metrics such a
labor costs. Managers ignored
other important things such as machine set up time. The equipment users wanted more efficient machinery, but were ignored.
With pressure from the machine makers and other various organizations,
the manufacturing field founded a completely new manufacturing system.
The measurement unit of this new accounting system is time. With time as the main metric, the cost accountants can make better
strategic decisions.
Drucker compares the
new conceptual model and traditional model of a factory by using a
flotilla (small group of ships) and battleship. The conceptual model being the flotilla, consists of modules centered
either on a stage in the production process or around a number of closely
related operations. To add to this
metaphor, each ship in the flotilla will be flexible in regard to the entire
manufacturing process and to the other modules. However, the traditional factory is like a battleship, i.e., a large, inflexible structure designed for one task. The flotilla model allows for changes in the production process in
order to respond to surges in market demand.
Use of the systems approach to emphasize the economic process of business
The systems approach is a concept that views
manufacturing as an integrated process that converts goods into “economic
satisfactions.” This concept does not
just consider the actual production of the product in factories.
The systems approach follows the product through its shipping process and
evaluates the impact of suppliers on the production process. Drucker explains that the system design approach “ . . . sees the plant
as little more that a wide place in the manufacturing stream.”
The manufacturing process does not end until the customer receives
his/her product.
Conclusion
Peter Drucker concluded that if the manufacturing industry simultaneously implemented these four principles of the post modern factory (the use of Statistical Quality Control to change the social organization of a factory, the new concept of manufacturing accounting allows people to make production decisions as business decisions, the use of “flotilla,” or module, organizations, and finally, the use of the systems approach to emphasize the economic process of business) they would eliminate existing conflicts and would create a factory that would be much more efficient than any current working factories.
