Step 5: Forge your solution
With all the information you have discovered, compare all your best ideas, against your Step two criteria for success. Choose the one that most closely matches your criteria.
With this done, spend time further developing your new strategy/plan/idea. How else can you make this even more successful? What are the ways you can make it even stronger as a solution? Creatively refining your solution can take time and effort, but it is well worth it.
