Fill the Grid and start the design loop
The ancient philosopher Plotinus created a well-known analogy of a sculptor cutting away that which does not enhance the desired image. This process is absolutely necessary for us.
What makes the Lean UX method very effective is its collaborative nature. The process begins in a meeting with the design team and client to identify users and, roles and desired outcomes. The grid is filled up with assumptions that will require further testing. This process is made in collaboration to align vision and expectations.
