The enhancement of producibility in a commercial or
defense enterprise can result in more satisfied customers and increased
profitability. The guidelines that have been presented in this document are
intended to provide assistance for achieving that enhancement. An attempt has
been made to provide a brief, simple, accurate overview of each item discussed.
The intent is to give the producibility novice, the producibility expert, and
everyone in between a useful reference tool.
Producibility, as defined by the PTF, is "the relative
ease by which a product can be manufactured as measured in yield, cycle times,
and the associated costs of options in product designs, manufacturing processes,
production and support systems, and tooling." Each of the five producibility
steps, as well as the producibility system elements within those steps, have
been presented here in enough detail and with sufficient references so that the
underlying techniques for improving producibility can be understood and further
explored. Whenever possible, case study examples and overview descriptions of
tools and techniques have been provided. Also, a series of three matrices for an
organization to self-assess its level of producibility development has been
included in the Introduction to assist in identifying and prioritizing areas for
As defined by the PTF, a producibility system is "the
integrated process and resources needed to successfully achieve producibility."
The intent has been to provide the reader with the basic concepts needed to
develop and continuously improve an effective producibility system. To do so
does not require that all the elements of every step be implemented. What is
required is an understanding of the elements and the steps and their
relationship to each other and to the specific enterprise whose producibility
system is being developed and improved.
The subject of producibility continues to improve and
change as various companies from various industries apply techniques such as
these, modify them, and thereby improve the state-of-the-art. Hence, it is
impossible to ensure completeness in any one document. These guidelines
represent the PTF's judgment of the key considerations applicable to a wide
range of manufacturing enterprises. The techniques and processes described
herein are not meant to be rigidly applied. Taken together, they provide a
useful, sufficiently complete guide to assist in improving producibility.
Throughout this document, the use of an Integrated
Product Team (IPT), which includes representatives of all the key functions of
the enterprise and its customers and suppliers, has been encouraged. It has been
demonstrated that an IPT, with the primary responsibility for implementing all
essential elements of producibility during design, development, and production,
can ensure that the tools for controlling processes and for understanding the
causes for, and solutions to, unacceptable product and process variability are
The key is management commitment. The five steps are the
building blocks. The application must be adapted to each enterprise based on its
products and its culture. The results can be impressive.
