José Ignacio López de Arriortúa

José Ignacio López de Arriortúa (born 18 January 1941) is a Spanish businessman who held senior positions at Opel, General Motors and Volkswagen.

He was known for his assertive style dealing with suppliers, managing lean production and driving down cost.

Lopez was born in Amorebieta, Basque Country, Spain, where his father ran a car repair workshop.

He studied manufacturing engineering and operations control in Bilbao.

He was awarded a Doctor of Engineering in 1966.

Lopez started his career at Westinghouse and Firestone in Spain.

Lopez joined GM in 1980.

Initially working at the Zaragoza plant, he became Head of Purchasing for GM's subsidiary Opel in Rüsselsheim in 1987.

There he established consumer price driven production methods dubbed "Purchased Input Concept Optimisation with Suppliers" or PICOS, which reversed commonly held supplier-manufacturer relations in the automotive industry.

When GM Europe President Jack Smith was promoted to CEO of the parent GM, Lopez was appointed global Vice President of Procurement where he relocated to Detroit, and applied his PICOS processes which resulted in reported savings of US$1bn.

After only one year in his position, Lopez abruptly resigned from GM in 1993, purportedly as executives decided to build an automotive plant with his lean production system in Poland or Hungary instead of his native Spain as initially promised.

Smith offered to promote Lopez to president of North American operations, but Lopez had already departed for Wolfsburg having accepted a position at Volkswagen.

In leaving Detroit, Lopez has claimed that his family wanted to return to Europe.

In 1993, Volkswagen poached Lopez and three GM purchasing executives, and he was appointed Head of Process Optimization and Procurement.

VW chairman Ferdinand Piëch who aimed to cut costs had wooed Lopez with the promise that a plant would be built in the Basque region of Spain, while Lopez's lean production system would be applied to the existing Wolfsburg plant.

GM immediately filed a civil suit against VW for corporate espionage for Lopez taking documents to VW relating to key GM trade secrets for factory operations, supplier prices, and Opel new car designs, plus Lopez's hiring would have violated his non-compete clause with GM.

Around the same time, in what was called the "Lopez Affair" by the press, German authorities raided the offices and homes of Lopez and the three former GM executives as part of an investigation that led to criminal charges being filed on December 12, 1996 (the charges were dropped in 1998), while US authorities unsuccessfully requested his extradition from Spain on similar charges.

Three days after a U.S. court in Detroit ruled that federal racketeering laws could be invoked in GM's civil suit against VW which could potentially result in triple damages, Lopez resigned from VW on November 30, 1996, which was also seen as a step for VW to distance itself from the scandal.

After resigning from VW in 1996, Lopez established a consulting practice in Spain and later on unsuccessfully attempted to establish a Spanish car company.

Lopez introduced a number of changes to the supply chains and production methods at Volkswagen and GM known as "Purchased Input Concept Optimisation with Suppliers" or PICOS.

The particular focus was on reduction of supplier prices so that a target end price of cars could be achieved.

While he was at Opel, the manufacturer's input prices continuously fell, while prices in the overall market increased.

The reduction in supplier prices was achieved by systematic price negotiations in a competitive market where a larger number of suppliers faced increasingly integrated car companies.

Lopez' success in those price negotiations that resulted in a positive impact on overall cost basis had been dubbed "Lopez Effect".

However, as suppliers increasingly struggled to deliver at cost, input part quality started to deteriorate which in turn had a negative effect car build quality.

The "Lopez Effect" is therefore used for both those effects.

Automotive News suggested that Lopez “knows all the tricks--how to use emotion, flattery, jokes, threats, ruthlessness, even lying if need be” to wring cuts from reluctant suppliers.

In an example of his strong-arm tactics, he was known to march "into a supplier's office, announcing that the company's work was subpar or overpriced, and issuing an edict for corrective action" for the supplier to keep its contract with GM.

It was suggested that Lopez even shared proprietary information with competitors to force lower bids from suppliers.

Supporters said that Lopez sent GM teams to a supplier to make it more competitive in terms of cost and quality, creating a "win-win" situation for the supplier and GM.

In 1997 a settlement was reached where VW paid $100 million in damages to GM, and agreed to buy $1 billion in GM parts over seven years.
