As with most issues, it starts at the bottom and works it's way up. With our company it's the component manufacturers who are driving the long lead times. Either they can't get a component to manufacture their item, or a lack of employees to put them into production among many other reasons. We now have a vendor putting a surcharge on top of an expediting fee to get components that are past due. Unfortunately our customer suffers then too. Seems it's only going to be time that will solve the issue.
