A Reuters report about Apple's supply chain scrambling to get screens ready because of the need to redesign a component is all well and good, but it's highly unlikely that the scrambling will lead to a delay in the release of the iPhone because of the complexity of Apple's supply chain. This is a point CEO Timothy D. Cook has made before, as he has questioned reading too much into a single data point.
"I don't want to comment on any particular rumor because I would spend my life doing that. But I would suggest it's good to question the accuracy of any kind of rumor about build plans and also stress that even if a particular data point were factual it would be impossible to accurately interpret the data point as to what it meant for our overall business because the supply chain is very complex and we obviously have multiple sources for things, yields might vary, supply performance can vary," Cook said on an earnings conference call in January. "The beginning inventory positions can vary; I mean there is just an inordinate long list of things that would make any single data point not a great proxy for what's going on."
