Every leader must have a vision. Particularly the CEO of a multi-billion dollar global corporation. Microsoft's bold and ambitious CEO, Satya Nadella, by virtue of his position, must, therefore, have a vision.
He must plan his company's strategies in view of the next 5, 10, 15 even 20 years. Literally. Consequently the short-term annual shifts we see occurring at the end/beginning of fiscal years are more often than not, the scheduled execution of predetermined objectives of the larger goal. Rather than the drastic untimely upheavals they may appear to be.
