									Project Selection and
Needs Identification
Identifying Design Category
   Creative
       New and innovative design
   Variant
       Variation of existing design
       Improve performance
       Add more features
   Routine
       Well known
       Combine creativity and new technologies
       Complex
Design Type Differences
   Each Design category can fall in one of the following types
       Technical evaluation project
           Use of new technology
       System test
           Ensure meeting all the needs
       Experimental design project
           Find system characteristics
       Analytical projects
           Find failure modes and probability of failures
       Applied research project
           Creation of new technology based on existing ones
       Fundamental Research Project
           Discover new scientific principles
Project Selection Criteria –
Questions to ask!
   What are trying to do? Articulate your goals
   How is it does today? Limitations?
   What difference does it make? Who cares?
   What are the risks and payoffs?
   How much will it cost?
   How long does it take?
   What are the benchmarks to check for
    success?
Project Selection Criteria –
Creating AHP Model
   Determine the selection criteria
       Your interests; technical complexity; creativity;
        innovation; marketing potential; etc.
   Determine the weighting for each criteria
   Create the AHP
   Review the scores and adjust as needed!
Project Selection Criteria –
Creating AHP Model
Identify the Needs
   What is the problem?                   Problem of
       Don’t fall for a wrong problem      Eliciting
                                             needs
       Make sure problem and solution
        are not given to you! – You have
        no design there!                   Marketing
                                             Spec.
   Understand the problem and
    need
   Do you have a design space –           Engineering
    all possible solutions                   Spec.
Process to obtain
Voice of the Customer
   Gather raw data from users
       What are the pros and cons of the existing process
       Understand the process and problem
   Interpret the raw data in terms of needs (Need)
       What is the customer requirement (marketing specification)
       Not quantified – they use terms such as: good, easy, user friendly, etc.
            Design an audio device that is portable, easy to use with high quality. (extension)
             It should be water resistance, long lasting, small and drop resistance.
   Quantify the needs (Tree)
       Establish an objective tree
       Ranking the relative importance of each specification
   Understand the background and existing solutions (Survey)
       Use all available resources: Internet, Technical, Journals, Government
        statistics, etc.
Example of
Objective Tree
    Sources for Survey
   EE Product Center, www.EEProductCenter.com. A website for locating electronic components and
    their manufacturers. It provides links to product datasheets and application notes. It has a keyword
    search engine and a tree structure search for finding components. For example, you can start with op
    amps and delve into subcategories such as precision and high-speed.
   Circuit www.CircuitCellar.com. This companion website for the magazine is a great reference for
    designers. It emphasizes embedded systems and electronics projects with many tutorial articles and
    project ideas.
   Datasheet Catalog, www.DatasheetCatalog.com. A datasheet source for electronic components and
    semiconductors.
   Dr. Dobbs, www.ddj.com. The magazine and companion website are a resource for software developers
    that includes tips and tutorials.
   EE Times, wLuw.EETimes.com. Industry newspaper for the electrical engineering field with
    information on current technology developments.
   Electronic Magazine, wwro.EDNmag.com This is a free magazine for electrical design engineers that
    provides information on the latest products. The website has a number of categorized technical
    resources and a design ideas section.
   OK Semiconductor, www.OnSemi.com. OK Semiconductor is a supplier of semiconductors for a wide
    range of applications, with a particular emphasis on power management. The website has a searchable
    database of over 15,000 components, and provides guidelines for component selection based on
    different applications.
   The Thomas Register, www.ThomasRegister.com. This is a source for finding companies and products
    in Korth America. It allows searches for parts and equipment that may be used in a design project. It
    provides profiles of companies that meet the search criteria and describes the products they make.
