Management Changes: Apple Inc. (NASDAQ:AAPL ), PepsiCo (PEP)

Siri’s co-creator leaves Apple

Adam Cheyer, who helped build Siri, the software Apple Inc.(NASDAQ:AAPL ) uses for its iPhone has quit the company according to knowledgeable sources. Cheyer was the co-founder of Siri, which was acquired by the California based company in April 2010.

Siri was integrated into iPhone 4S last year. However, users have complained that the experience is not as great as portrayed in Apple’s commercials.

Apple’s Chief Executive Tim Cook had admitted earlier this year that Siri has the potential to do much more than what it offers now. When questioned about the shortcomings of the software in May, Cook had said, “We have a lot of people working on this.”  He had also said, “And I think you will be really pleased with some of the things you’re going to see over the coming months.” The software in the new iPhone to be released today may have some additional features.

The iPhone maker is also partnering with automobile companies like General Motors, Toyota Motor Corp and Daimler AG to integrate the software into their cars.

President of PepsiCo quits

Meanwhile, soda and snack food maker PepsiCo, Inc.(NYSE:PEP) has announced that John Compton, its president for less than a year is leaving to become CEO of a privately held company and that the exit is effective immediately. Compton, who had joined Pepsi at the age of 21, had been appointed president only in March.

The New York based company also announced his successor, Zein Abdalla, currently the CEO of its Europe division. Further, the company stated that Enderson Guimaraes, president of the company's global nutrition group, will head PepsiCo Europe. Compton’s appointment had been part of restructuring by the company for creating a strong pool of likely successors to CEO Indra Nooyi.

Compton will head Pilot Flying J Oil Corp, which runs travel centers and truck stops and is based in Tennessee.
