#OpenBooks

If you’re a parts supplier to General Motors, you have two choices: bid for business as it comes up or open your books and factories to skip the bidding process.

According to Automotive News, the latter option is part of GM’s One Cost Model launched in 2013, allowing the automaker to analyse a supplier’s internal cost data to identify cost-cutting opportunities. In exchange, suppliers can receive exclusive parts contracts that can last the lifecycle of a model and GM will not put that particular piece of business up for bid.

This all requires a significant amount of trust from suppliers, a commodity which has been lacking at GM since the ’90s.
