Looking at 2019 and planning to do things differently inevitably brings us face-to-face with the need to innovate. But innovation is a widely misunderstood concept. First, ideas are not equal to innovation. To innovate we must do more than think of a cool new way things could be done, the idea must also work. The whiteboard exercise means nothing until the new thinking delivers value. Second, innovation is rarely a lightbulb moment - it generally emerges from organised and disciplined search. If you have identified a need to innovate, and you are wondering how to start, you could do a lot worse than ponder the seven sources of innovation identified by Peter Drucker in his 1985 classic "Innovation and Entrepreneurship - practice and principles".
