Twitter CEO Jack Dorsey announced a sweeping reorganization at the social media network on Thursday, just as Ed Ho, a vice president of product and engineering, announced he would step down into a part-time position.

The change organizes Twitter into functional groups, such as engineering, instead of around individual products, which Dorsey said in a series of tweets would help the company be quicker and more creative over the next decade.
