You have been approached by one of your clients to design a concrete mixer for use by a small building contractor or DIY enthusiast. The only initial request by the client is that the mixer should be marketable (competitive with regards to price), durable, economical to operate, and relatively easy to transport, e.g. by using a small truck or trailer.
Do your own research to come up with an applicable set of attributes. A risk assessment is required.
Document all the steps of your design process including any lists, trees, structures, charts, and tables. Start by selecting applicable attributes for the mixer, and end with choosing a suitable design.
After completing the design, draft a letter to the client describing the design process. Include your motivation for deciding on the particular attributes, why any constraints were selected, and why you decided on the final design.

The submission should include:
• Problem statement

• Design attributes (objectives, constraints, functions, and means) and rank the key objectives
• Functional structure
• Design specifications
• Conceptual design (morphological chart, comparison of designs)
• Risk assessment (risks associated with the use of the product)
• Letter to the client
