Define the Problem: Figure out who has a problem, what it is, and why it needs to be solved. Define Sub-Problems: Break your main problem down into smaller, easier to solve sub-problems.
Determine the Criteria: Decide what conditions would need to be met for the problem to be considered "solved."
Determine the Constraints: Determine what limitations are in place before any solution is considered.
Prioritize the Criteria and Constraints: Put the criteria and constraints in order from most important to least important.
Generate Solutions: Brainstorm, evaluate and refine your ideas, and choose the best solution from your list of priorities.
