Using the "Problem Solving Process"

In order to use the Problem Solving Process, you first need to identify the problem. In this case, you're hungry, and want a peanut butter and jelly sandwich.
You go into your kitchen pantry and see that you have the proper ingredients. You also know the steps on how to make the peanut butter and jelly sandwich. This part of the process is step 2, planning your solution.
Now that you know what to do, the next step is carrying out the plan. Once you're done carrying out the plan, you have a whole sandwich, and you're no longer hungry.
The final step of the problem solving process is reviewing over the entire process. Ask yourself, "What could I do better?" Or "What went wrong?" Once you know how you can improve on the situation, take them into consideration.
