I am a follower of Peter Drucker. He had many profound sayings, but probably the most significant was abandonment. He saw abandonment as the key to innovation. Abandonment freeing both time and money away from activities that weren’t working into new initiatives.

Companies that have followed his thinking have even instituted abandonment days, once a month. Each team has to come up with one process / practice that they are abandoning. Search for “abandonment + Drucker” and explore.
