Quoting:
"Former Microsoft developer and head of Windows 7 and Windows 8 development, Steven Sinofsky, has published his own thoughts on the topic, and we recommend giving his article a read. One of the points Sinofsky makes is that Apple has, over the last decade, created an ecosystem that saw it go from a small phone vendor to a major player. It took an OS originally developed to run on the NeXT workstation, ported that OS to PowerPC, then to the x86 architecture, and finally to ARM. It ramped up its own CPU development team and now leads the mobile market in ARM single-threaded performance. It has done all this while simultaneously iterating on iOS, year after year.
As Sinofsky points out, we tend to talk about development as if its three goals — the so-called “iron triangle” of quality of release, pace of change, and the adding of new features — exist in a zero-sum game. It is, to be sure, much more difficult to develop solutions that balance all three of these requirements than to focus unilaterally on just one of them. But this is a balancing act that Apple has been performing fairly well for a decade, across an ecosystem Sinofsky considers without peer, save possibly for that of IBM and its System/360. The idea that companies choose one, and only one of these criteria to focus on is something he dismisses (...)"
