> No. Shorter release cycles don't imply loss of quality. I claim the opposite in fact. Rolling releases are much better for quality. You're releasing smaller more focused features and battle-testing them in the field.The jury is out on this. We have seen that longer release cycles with teams that take things seriously can be very successful (mission critical software). We've also seen that short release cycles can be very effective. The context of your software matters a great deal here, as well as the basic mechanics of how your software is delivered. You can't just take the philosophies of web sites and apply them across the board and declare it objective fact:
1. Take for example the fact that with a web service you can deploy quickly to a small subset of users, and grow it as it proves itself. This is quite ideal, but regardless of whether its even practically possible with OS software, its certainly not what Apple does. The combination of a short release cycle with a worldwide release means that "catching your bug" may mean catastrophic data loss for a large amount of customers.
2. With a web service you have the option of rolling back a bad version, or, simply deploying yet another release. Again, whether its possible with OS's or not, Apple certainly doesn't (or can't?) employ this strategy. The best they can do oftentimes is simply remove the update, but everyone that has it installed keeps having the bug until a) your fix is out and b) they actually install said fix.
> There are always stabilization phases. Not every major release will be an overhaul. Most will be incremental updates.
There certainly could be stabilization phases, but the proof is in the pudding and thats not how it feels. All the last releases have seen major additions, and most the regressions I run into either take years to fix (dual monitor support) or still remain increasingly broken (Messages to name just one example). There is a simple reality to having a year to stabilize without the pressure of a PR push of new features vs. balancing your stabilization with coming up with compelling things to slap on a website and show in a keynote.
