The article discusses the importance of three concepts - actual, potential, and action - in product management and creating tangible success.
Actual represents the current situation or state, such as the current state of a product or available resources and infrastructure.
Potential refers to the imagined future state of a work, like the envisioned sculpture from a marble block or the defined wireframe of a product.
Action represents the steps or tasks needed to move from the actual to potential, like carving and shaping the marble for a sculptor or creating requirements in product management.
