For years, you've written using pens and mechanical pencils. Compare five pencils and pens. Talk about your most important design parameters. Compare the pros and cons of each arrangement. Provide a design picture for each finalist. Write a one- to two-page report on your research?

For each of the scenarios below please describe what would be the best design pattern to be used, explain the appropriateness and advantages of using that pattern, and draw a corresponding design diagram for that scenario including that pattern. Describe the participants and collaborations. Please respond to all of the above 4. There is a system configured to work with three pretzel stores: Pretzel Maker, Wetzel, and Auntie Anne's. They create similar yet custom-made pretzels, and the system needs to be independent from the way the pretzels are created. Each pretzel store uses its own ingredients (products), yet similar to the other stores. They each use their own kind of dough, cheese, and sauce.
