John Ternus is reshaping the Apple CEO role around product engineering and design, while leaving more financial and supply-chain responsibility to the executives who already run those organizations. The division reflects his technical background and creates a clear contrast with Tim Cook’s operations-heavy leadership style.
Bloomberg’s Mark Gurman reports that Chief Financial Officer Kevan Parekh is handling much of the financial operation, while Chief Operating Officer Sabih Khan oversees the supply chain. Ternus is spending more time with hardware chief Johny Srouji, engineering leader Tom Marieb and Apple’s design teams.
“There will be differences in where we spend our time, but the mission, the goals are the same.”

Ternus reportedly reached that conclusion after Cook told him that a new CEO should concentrate on the areas where he can add the most value. For Ternus, that means using decades of hardware experience to influence products earlier instead of trying to reproduce Cook’s personal approach to finance, policy and operations.

A different allocation of executive attention
The shift does not make operations less important. Apple still depends on a complex global supply chain, careful spending and government relationships. It instead gives Parekh and Khan more room to manage their specialties while Ternus focuses on development decisions that can determine whether a new device succeeds.
MacObserver has already covered Ternus’s effort to make Apple faster and leaner. His personal schedule now shows the product side of that strategy, with design and engineering receiving the attention Cook once directed toward logistics and corporate diplomacy.
