Leadership Lessons
Large-scale transformation succeeds when executive alignment is established before technology decisions are made. Every major outcome traced back to one of five executive decisions taken early.
Key takeaway
The decision to transform was not a technology decision. It was a business decision made by leaders who understood the cost of standing still.
