Cost savings generated through the bidding process will reduce GM's spending rate for IT services below the projected five-year, $15 billion level, according to the company. But Szygenda said that any savings may be reinvested in new IT projects.

Now that the major IT services contracts have been awarded, GM will focus on ensuring a smooth transition over the next five months, Szygenda said. He added that his primary goals are to avoid any disruptions to GM's business and to make sure that the IT efforts fully support the company's global operations.
