A key practice of Agile is a sprint. A sprint is a short, focused, commitment to accomplish a definable set of tasks. Often, these sprints last one to two weeks.
By making a commitment to achieve something that is definable, it is possible for a individual or team to then reflect on what was accomplished over that short period of time. By doing a Reflection in this effort, insights are illuminated that help define the goals of the next sprint.
This process creates a tightly defined Learning Cycle that accelerates the speed of learning.
Each Learning Cycle begins with a set of assumptions. But, with each sprint, as you Walk into the Unknown, some of those assumptions will be proven wrong. Deep learning happens when we find those wrong assumptions and redefine them and testing them until they are no longer assumptions but become new "knowns". This process increase our Creative Confidence as we plunge into the next sprint.
Failure is defined by those wrong assumptions. The faster we Fail Forward and understand and redefine those assumptions, the faster we learn. Failure, then, is not to be avoided in the process. Indeed, in failure is the very essence of the learning.
As we begin to understand this truth, we can move through our Fear of Failure.
