Understanding the Enterprise Value of Test: Characterizing System Test Discrepancies in the Spacecraft Industry - Weigel, Annalisa L.
This paper highlights research characterizing the distribution and time impacts of spacecraft discrepancies found at the system level of integration and test. Reducing discrepancies will result in cycle time reduction and cost savings, as well as increased product quality and reliability. All of these potential outcomes are indications of successful progress toward becoming a lean organization.

The Lean Value Principle in Military Aerospace Product Development - Slack, Robert
This document takes a critical look at the first lean principle, Value. The meaning of value is ivestigated in: 1.) general context, 2.) product development context and 3.) the business literature context. Insights about the linkages between the value perspective and customer value are also covered.

Lean Implementation Considerations in Factory Operations of Low Volume/High Complexity Production Systems - Shields, Thomas J.
The researchers of the Lean Aircraft Initiative developed a hypothesized lean implementation model seeking to provide its members guidance on implementing lean transitions in factory operations of low volume/high complexity production systems.
Following the development of the hypothesized lean
implementation model, twelve case studies were used to test the model. This report details the model and analyzes the case studies using the model as a framework.

Implementation Workshop: High Performance Work Organizations - Klein, Janice; Cutcher-Gershenfeld, Joel; Barrett, Betty
A report on findings from the first Lean Aircraft Initiative (LAI) Implementation Workshop held on February 5-6, 1997. The report is not a "cookbook" or a "how to" manual. Rather, it is a summary of the first phase in a learning process. It is designed to codify lessons learned, facilitate diffusion among people not at the session, and set the stage for further learning about implementation.

Lean Aircraft Initiative Implementation Workshop: Implementing Cross-Functional Teams in an IPPD Environment - Cutcher-Gershenfeld, Joel; Klein, Jan; Pomponi, Renata
There is an emerging consensus in the Aerospace sector around the importance of Integrated Product and Process Development (IPPD). Now nearly every
new program is now established around a set of Integrated Product Teams (IPTs).
In order to learn more about the experience to date, 14 teams from across the Lean Aerospace Consortium were brought together. Each team featured a mix of 3-5 organizational representatives. The broad goals of the session included: providing a constructive learning experience for the participants and generating insights that might be of value to the larger consortium.

Lean Aircraft Initiative Implementation Workshop #3:
Customer and Supplier Integration Across the Supply Chain - Cutcher-Gershenfeld, Joel; Bertelli, Dominick
The integration of customers and suppliers along the supply chain involves a fundamental transformation of the way business is conducted in the Aerospace industry. Lean Aerospace Initiative (LAI) members, as well as representatives from their supplier base, had the opportunity to examine this challenge and the dynamics of implementing system-wide change during the third implementation workshop sponsored by LAI, February 12-13, 1998 in Palm Beach Gardens, Florida.

Summary Report: Systematic IPT Integration in Lean Development Programs - Browning, Tyson R.
This document provides a summary report of the M.I.T. Masters Thesis, "Systematic IPT Integration in Lean Development Programs" by Tyson R. Browning. These studies argue for the inclusion of program integration principles as an essential aspect of lean enterprise product development and organization.

Axiomatic Deisgn of Manufacturing Systems - Cochran, David; Reynal, Vicente
This paper introduces the use of axiomatic design in the design of manufacturing systems. The two primary functional requirements of any manufacturing system are developed. These functional requirements are then used to analyze the design of four manufacturing systems in terms of system performance.The purpose of this work is to provide a new foundation for describing, determining, and rationalizing the design of any new manufacturing system.

Labor Support Survey Summary Report - Klein, Janice
One of the main cost drivers in the defense aerospace industry is overhead personnel. Traditionally, labor support ratios have been used as an efficiency measure and to control overhead levels. This report outlines the survey responses and analysis and summarizes the potential factors influencing labor support ratios.

Understanding Lean Manufacturing According to Axiomatic Design Principles - Reynal, Vicente A.; Cochran, David S.
In this paper, a sequence of implementation steps will be developed through the application of axiomatic design. This sequence will provide a design methodology for lean production which connects manufacturing system design objectives to operation design parameters.

Acquisition Reform - Sapolsky, Harvey; McKinney, Ethan; Gholz, Eugene
This report reviews the six most recent major acquisition reform reports, starting in 1949 with the Hoover Commissions and including McNamara's Total Package Procurement, Fitzhugh Commission, the Commission on Government Procurement,the Grace Commission, and ending with the Packard Commission report in 1986.
The reports' recommendations are devided into six areas: centralized procurement, professionalization of the acquisition corps, management improvements, changes in contracting procedures, new development strategies, and legislative/executive relations.

Factory Flow Benchmarking Report - Shields, Thomas J.
LAI benchmarked representative part fabrications and some assembly operations within its member companies of the defense aircraft industry. This paper reports the results of this benchmarking effort. In addition, this report explores the major components of the cycle time: fabrication time, lot process delay, storage delay, and transportation delay.

A HOLISTIC APPROACH TO MANUFACTURING SYSTEM DESIGN IN THE DEFENSE AEROSPACE INDUSTRY - Vaughn, Amando F.; Shields, Tom
Manufacturing has evolved to become a critical
element of the competitive skill set of defense
aerospace firms. Given the changes in the
acquisition environment and culture; traditional
â??thrown over the wallâ?? means of developing
and manufacturing products are insufficient.
Also, manufacturing systems are complex
systems that need to be carefully designed in a
holistic manner and there are shortcomings
with available tools and methods to assist in the
design of these systems. This paper outlines the
generation and validation of a framework to
guide this manufacturing system design process.
