Brief - A concise statement or summary about something you're doing or working on. It can be questions that you want to answer at the beginning or end of the assignment or maybe a project you were or are working on.

Research - Looking up information that will tell you about the thing you were looking up. This can guide you to your answers and help whatever you're working on be more successful. Research teaches you new things and can help you learn more about whatever your researching.

Idea and Brainstorming - Using all of your research and information that you gathered to come up with ideas and possible successful outcomes. Your thinking about what can work what's most interesting to you and why then you pick what idea is the best and seems most successful.

Prototype - A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users.

Testing - Taking everything you have done with the prototype and starting the project. When you start you write down what works and what doesn't making sure everything works right. Then if you have to fix the problems with your prototype so you can get it working perfectly and how you want it to be working.

Evaluation - Making sure everything is in place and is working correctly, also making sure it is safe to use. So that now if you have to you can rework something that needs to be fixed. Then if everything is correct you can release the finished project, if that was the whole idea.
