During this step, solutions can be critically evaluated based on their credibility, completeness, and worth.
I had to critically evaluate several solutions recently when I was upgrading my custom gaming PC. Before choosing a new processor and my new graphics card, I spent hours analyzing benchmark tests and hardware reviews to ensure the components were worth the high price tag. If I had just bought the first parts I saw without verifying their credibility, I could have ended up with a severely bottlenecked system. Taking the time to properly assess all your options is just as important in solo projects as it is in group problem-solving.
