I worked at a big tech for many years and my team never managed to get Scrum working properly. Every year my team commits a delivering certain product/features at a very specific date (some sort of launch event), so we have to know very early in the year what's all the work required and report periodically whether project is on track. The deadlines are also always on the tighter end. The flexibility of Scrum becomes an issue in that case, because not everyone can deliver the same tasks at the same speed and without careful planning you can easily miss important deadlines.
