The design of every equipment has the effect of determining its durability, cost, and usability. The international CTT group engaged in a project of building a prototype office cart that could be used to carry various products in an office setting.
Development of a Target Specification
            In order to develop our prototype, we first shared ideas on the carrying capacity of the cart, its portability, its height, and the number of levels needed so that items can be properly arranged in the tray. We agreed to add a trash page to the design. We also agreed that we should put wheels to the cart so that it can be portable. The prototype was to have three levels, four wheels, brackets on all its corners, and hooks on one side of the second and third level.
Presentation Target Specification
The cart had four wheels that had a brake system. The handle measured 2 inches by 1.5 inches. The cart had a height of thirty-four inches and a width of two inches. One end of the cart had a trash section that had a height of 39 inches, a length of 19 inches, and a width of 11 inches.
Discussion and Presentation of a Level 2 Prototype
The level two prototype is a physical presentation of the final cart. The cart was designed according to the dimensions used in prototype two. The cart was designed to have a dustbin section and three level. Each level can carry items in two trays. It also has wheels to ensure that it is portable.
Lessons Learned
I was able to learn on the importance of taking accurate measures in the design of products. In particular, I understood that wrong measurements can affect the overall design of a final product. I was also able to learn on the importance of team work. When designing the prototype, we worked as a team and shared various ideas on design.

The final product architecture, which has the title “after assembly,” will be made by joining the various parts of the incomplete diagram above. Brackets will be used to join the sections of the unassembled cart so as to form the complete cart.
