This is a fundamental practice of quality management. In the 'Total Quality Management' approach (inspired by Deming's work) the idea is called Kansei and it essentially means: watching how the user users the product will lead to improvements in the product. We see how this has worked well for Agile and Scrum, methodologies in which customer collaboration and feedback are frequent.

The four main principles of the TQM idea are:

Kaizen: Continuous Process Improvement

Atarimae Hinshitsu: things should work as they are supposed to

Kansei: understanding how the user uses the product will lead to improvements in the product

Miryokuteki Hinshitsu: things should have an aesthetic quality, be pleasant
