How important is the agile "test and learn" approach?

(Or as we like to say – Mistakes are not just ok – we insist!)

Agile is essentially about developing solutions quickly. Iterating quickly. Adapting. Not quite right? Change. Go Again. Lets test. Adapt. Change. Learn. Improve. You get the idea.

So how important is the TEST AND LEARN approach in business?

1. Planning where we are going first. Where do we regroup? How are we going to proceed to get to our first destination? Do we need to take a stride or a small step based on what we know about our challenge?
2. Talking with each other to make sure we are still together on our journey, do we need to balance each other? Has someone learnt new information?
3. We pause along the way to talk about if we are still aligned to our overall destination. Do we hear the noise from the destination?
4. Listen for feedback. Do we hear water? Is there an echo? What was that sound?
5. Learning along the way, we pause regularly to see what we are doing right and what we need to change. Was tying us together helpful as we walk through the dark, or did we trip on the rope?
