completed design What is its purpose What are its specifications How do you build it How do you test it How do you know it meets specifications How do you maintain it What does it cost Can t Separate a Design From Its Documentation Georgla mg tiTechmtol W Smith 2008 ECE4007 L4 4 The Design Process for ECE4007 Project Selection and Team Formation Project Proposal Conceptual Design A formal written proposal is required Your project section may also require a presentation Preliminary Design Review A group presentation and documentation package are required Your project section may also require a written report Final Design Presentation Groupteam presentation Final Design Report Formal written report with complete technical documentation Project Demonstration Demonstrate all aspects of your project working or not Georgla mg tiTechmitol W Smith 2008 ECE4007 L4 5 Outline Proposal Specifications Codes and standards Logistics Labs Ordering Parts etc Georgla mg tiTechmitol W Smith 2008 ECE4007 L4 6 Project Proposal Proposal purposes Explain the basic concept of the project State the project goals from a nontechnical point of view Present the specifications and design approach Present the project tasks and schedule Plan for demonstration and testing Present marketing and cost analysis The proposal justifies the project to both technical and nontechnical management The proposal if accepted becomes a contract between the design team and whoever is funding the project for ECE4007 consider the source of funding to be your project advisor Should be optimistic but realistic Georgla mg thechmitol W Smith 2008 ECE4007 L4 7 Sections of the Proposal Executive Summary Introduction Objective Motivation Background Project Description and Goals Technical Specifications Design Approach and Details Design Approach Codes and Standards Constraints Alternatives and Tradeoffs Schedule Tasks and Milestones Project Demonstration Marketing and Cost Analysis Marketing Analysis Cost Analysis Summary and Conclusions References and Bibliography Refer to the template to be posted to the 4007 website for detailed information Georgla mg thechmitol W Smith 2008 ECE4007 L4 8 l Proposal Logistics All teams in all sections must complete a formal written proposal Proposals are due at the beginning of lecture on Monday 15 September There will be a penalty for late proposals Each group will place a copy on their web site Proposals will be jointly graded by the UPCP and your project advisor There is no specific length requirement for the proposal but all teams must use the template posted on the course website Georgla mg tiTechmitol W Smith 2008 ECE4007 L4 9 Proposal Logistics continued This week Technical specifications Codes and standards Schedule Budget Other proposal sections Example proposals General writing expectations Georgla mg tiTechmitol W Smith 2008 ECE4007 L4 10 Technical Design Specifications For the proposal the technical specifications summarize the project requirements The specifications answer two questions What is the problem that the design is to solve How will we know when it s done The process of determining the specifications starts with working with the customer to assess the needs and separate them from the wants Nontechnical and nonquantified possibly contradictory Section 2 of the proposal Translate needs to specifications Complete consistent and noncontradictory Rely upon experts similar designs and tests experiments Difficult process usually done by experienced engineers Georgla mg thechmitol W Smith

design project If your project doesn t meet specifications you can lose credibility as an engineer and you or your company may lose a lot of money Better to be careful and accurate up front than to deal with a big disaster at the end It is unethical to agree to meet specifications that you know you can t meet But it is ethical to agree to try to meet specifications that you believe are achievable but might not be Georgla mg thechmitol W Smith 2008 ECE4007 L4 16 Codes and Standards Codes and standards may be part of your specifications or may influence your specifications It is required that each team address appropriate codes and standards Need to identify several standards that apply to your design and summarize how they may affect your design decisions This task should not be difficult don t make it harder than it really is Georgla mg ffTechmitol W Smith 2008 ECE4007 L4 17 Examples of Codes and Standards Communications standards USB Parallel Port Logic family interface specifications CMOS TTL National Electric Code CE Marking electromagnetic safety Safety standards eg UL Various lEEE standards Workmanship standards eg soldering wiring Georgla mg thechmitol W Smith 2008 ECE4007 L4 18 Strategies for Considering Codes and Standards Incorporate what you know USB R8232 GPIB Parallel Port etc Ask your project advisor Search on the internet wwwieeeorqstandardseducation If you are working with line voltages be sure to use appropriate safety standards for your own protection Georgla mg tiTechmitol W Smith 2008 ECE4007 L4 19 Outline
