GM Continues Overall Improvement in Annual Harbour Report on Productivity

Email   small font medium font large font

General Motors Corp. improved overall productivity, despite an 8 percent production volume decrease last year, according to "The Harbour Report North America 2008." The Harbour Report measures North American automotive manufacturers' assembly, powertrain and stamping plant productivity.

GM is the only manufacturer to consistently improve year-over-year overall in the history of the annual report. The company's Toledo, Ohio, transmission plant was the most productive transmission plant in North America for the second year in a row, at 2.37 hours per transmission.

Additionally, three of GM's assembly plants, five of its engine plants and two stamping plants were ranked in the top 10 in productivity in their respective categories. GM improved its overall manufacturing productivity slightly by 0.2 percent over last year.

Gary Cowger, GM group vice president of Global Manufacturing and Labor Relations, maintains that GM's Global Manufacturing System (GMS) has helped GM sustain its year-over-year overall productivity improvements by helping the company build vehicles more efficiently.

"For GM to have taken out volume and launched several new products last year and still show a positive overall productivity improvement, speaks very strongly for GMS and the entire North American team, including union leadership, management and our employees," said Cowger. "GM has consistently improved productivity, and is the only manufacturer to show year-over-year improvements for the last 15 years of the Harbour study."

GM's efficiency gains have also been fueled by the company's continued improvements in product quality.

"GM's productivity improvements are also directly tied to our commitment to capture industry leadership in quality," added Cowger. "Building higher quality products allow our manufacturing operations to run more efficiently by eliminating all forms of waste."

In the recent J.D. Power Initial Quality Study, GM accomplished a 9 percent year-over-year improvement, outpacing the industry while achieving its best PPH (problems per hundred) levels ever. The company won three segments: Chevrolet Malibu (Midsize Car), Pontiac Grand Prix (Large Car), Chevrolet Silverado LD Classic (Large Pickup), and its Fairfax, Kan. assembly plant received the Bronze plant award.

"What's interesting is that this year we continue to see improvement among all companies despite the fact that there have been dramatic changes in the environment in which they operate -- significant volume losses particularly in segments such as full-size trucks and SUVs," said Ron Harbour, Managing Partner of Oliver Wyman's North American Automotive Practice. "The fact that GM has continued consistent improvement says a lot toward what the company has done in terms of implementing GMS and the maturation of that process."

"We are pleased that UAW-GM assembly facilities scored higher than Toyota assembly facilities, and our Toledo transmission plant was number one for the second year in a row," said UAW vice president Cal Rapson. "But it's clear that all manufacturers are upping their game and we need to focus on improvements to stay in front."

Some of GM's productivity highlights in the Harbour Report include:

GM SPO Vancouver, Canada, was named Most Productive Warehouse in North America out of over 200 parts warehouses and 31 OEMs. And, GM SPO's Denver Parts Distribution Center (PDC) was in the number one Most Improved Warehouse Award, with six other GM SPO facilities in the top 10.
