In Leadership Aperture and Innovation, we explore how the aperture you bring shapes the kind of innovation you create. Narrow aperture fosters incremental improvements, medium aperture enables systemic redesigns, and wide aperture opens the door to transformational breakthroughs. Each aperture has value, but leaders must learn to recognize which aperture is needed, when, and how to balance them as a portfolio. By becoming fluent in shifting aperture, leaders can avoid the trap of misalignment—pursuing big bets when small improvements would suffice, or clinging to tweaks when transformation is required.
