  1. Project SpecificationsJohn Ayers .

  2. Specifications (defined) • They list the requirements that the project must meet. • There are different types of specifications, including those for hardware and software.

  3. Specifications (explained) • A key concept underlying the specifications is that any competent engineering team should be able to design a device that performs the function that is desired. • Specifications determine what is to be built, but do NOT provide any information about how to build the device.

  4. Specifications (warnings) • In general, you should NOT specify any components. • However, if you are modifying an existing devicehardware or software you must describe the current device in as must detail as possible.

  5. Format for Specifications • Should be typed and written in third person • Should include the following three parts: - Title page - Introduction and Overview - Technical Specifications

  6. Title Page a. Course name (ECE 290) and term b. Project Title: Specifications c. Team Members d. Project Sponsor

  7. Introduction and Overview • State the purpose of the project clearly. - Why are you building the device? - What will the finished device do? • Describe the project carefully. - How will the device operate? - What is unusual about the device?

  8. Technical Specifications This section contains, in a tabular form, all of the facts and figures needed to undertake the design project.
