Chris Hall and Josh McArthur
Boeing was founded on July 15, 1916 by William E. Boeing as Pacific Aero Products
Became Boeing Airplane Company in 1917 First “modern” plane, the 247 built in 1933 Government regulations force a split into Boeing
Airplane Co. and United Airlines in 1934 Built B-17 bombers in WW2, peak production was
350 planes a month First commercial jet, the 707, introduced in 1958 1967 the 737 is introduced, the top selling plane of
all time. It is still being manufactured with modern updates
Top contractor for the International Space Station Lost its market leadership position to Airbus in 2003

ORDERSORDERS
A set of tools to reduce waste and create process flow
Developed by Toyota Includes value stream mapping, 5S, kanban,
and error-proofing ( poka-yoke ), and production leveling
Reduction of 3 types of waste: Non-value-added work ( muda ) Overburdened systems ( muri ) Unevenness ( mura )
Incorporates JIT and “smart automation” Inventory turns are a common lean measure
In the early 90’s Boeing realized it needed to improve its process flow
Executives were sent to Japan to study JIT, error free production, and process flow
Consultants were hired from Shingijutsu Co., a group of former Toyota executives
“To make planes is to make and develop people” – Chihiro Nakao it’s all about training
Boeing took over manufacture of the Apache in 1997
Cycle time was increasing and quality slipping
22 aircraft in inventory for a 2 per month delivery
Huge inventory costs
Manpower reduced and more direct work on the helicopters was achieved
Factory floor redesigned by building wood and styrofoam models
Tools and parts arranged for minimal movement
Support cells moved alongside the aircraft Process targeted for 75% reduction, 72%
was achieved in the first year Takt time is 2.75 days, calculated from
customer demand, creating a “pulse line”
85% reduction in hours to assemble an Apache, 54% in total build time
218% increase in build rate 87 inspectors now working as mechanics,
now only 16 auditors remain Overtime costs reduced from 20% to 3-
5% $8 million per month saved in inventory
costs
1500 executives trained in Japan over a 3 year period
50 master six-sigma black belts, over 100 green belts
3-400 trained in kaizen Toyota consultants hired for 350 billed
weeks/year, now down to about 100/year
Boeing worked backward from the plant exit to reorient the line, from a 2 line slant build to a single nose to tail
This change helped implement a moving line system
60% of the time was spent away from the plane, so point of use kitting was incorporated
Boeing is working with suppliers to use a JIT system on the 737 line
The goal is first contact by a Boeing employee is attaching the part to the aircraft
Flow time reduced from 28 days to 22, 15, and now 11 days
Moving line is set at 2 inches per minute, calibrated to team task times with point of use kits
Crane moves reduced by 39% Flow times improved by 30% Inventory levels dropped by 42% Floor space reduced by 216,000 square
feet
Woven Electronics improved inventory turns from 7 in 2000 to 26 in 2006, and will soon achieve one-piece flow
Interior manufacturers reduced flow time for overhead storage bays from 140 days to 4
Wing production facilities have created a savings of $58,000 per set of wings, and have a goal of $100,000
Non value added steps being removed allowed a rework of the variable labor scheduling, resulting in a new computerized scheduling optimizer. The Result, $200,000 in initial savings and $40,000/yr in reduced time and paperwork costs
Improved requisition process allows early negotiation with suppliers and customers
New office supplies procurement system tracks thousands of commonly used items at various facilities
Renton lake facility reorganized after a 2001 earthquake destroyed
Consolidation reduced square footage by 40%, forcing more efficient organization.
Managers and engineers offices overlook the factory floor, with glass and plastic barriers to allow them observation points. Factory sounds filter into the office environment
This setup keeps everyone focused on the final result, a better, more efficient plane
