It might be required to break down the org chart so that each executive gets his/her own page to avoid congesting the chart. Synchronization allows any change made to the executives in other pages to remain in sync with the main page.
To synchronize a shape, click the shape and then the Synchronize button in the Org Chart tab.
This opens the Create Synchronized Copy dialog box, which allows to create a copy of the shape and its subordinates on a new or an existing page.
Click the Hide subordinates on original page checkbox, if you want to collapse the shape on the main page. Any changes made on the synchronized shape pages will be seen on the main page as well.
