Study (also called Check)

Now study the results. Your goal is to understand what worked and what did not, and add to it what you know about the proposed changes.

• What positive and negative things did we learn?
• Will the experiment work on a large scale? Why or why not?
• If it will not work, what can be done to make it work?

Only now can you make an informed decision. You may have to go back to one of the previous stages, or you might be able to go onto the next stage.
