What do we hope to accomplish?If you are uncertain as to what you will have accomplished when you are done, you will have no idea of how to know whether you have met the goal yet. It is completely legitimate to change your objective once new information uncovers that another course makes more sense.
In which order do we want to deliver what?
How do we Inspect and Adapt?
We can not remove uncertainty by drawing a straight line through uncharted territory - but what we can do: Take small steps, then carefully plan the next step.
Your Inspect+Adapt plan also needs to include how you will know whether you have made progress in the right direction - or not. Using direct customer interaction is as valid as some Big Data solution like Google Analytics or Omniture. Just make sure you choose the one that suits your needs.
What do we need to succeed?You should be clear what you will need to be successful. The Bible states, For which of you, desiring to build a tower, does not first sit down and count the cost, whether he has enough to complete it? Otherwise, when he has laid a foundation and is not able to finish, all who see it begin to mock him, saying, ‘This man began to build and was not able to finish'
