Engineering specification

Engineering specification

1. understand the problem

   • quality products
     • customers
   • time delay
     • overcost

2. requirements

   • creeping specifications
     • changes
       • new technologies
   • comunication
     • effective design

3. QFD method

   • organized
     • develop the major pieces of information necessary to understand the problem
       • hear the costumer
       • develop specifications for the product
       • finding costumers desires
       • determine if the competition meet the goal
       • numerical targets
   • developed in Japan
     • in the 70's
   • Toyota uses for reduce the costs
   • The QFD technique ensures that the problem is well understood

4. to identify the costymers

   • we ask
     • who
       • the costumer are
     • what
       • they want to do the product
     • who vs what
       • identify how the problem is solved
     • now; now vs what
     • how
       • you measure the satisfying
     • what vs how
       • target info
     • how much
     • how vs how
       • details of all of steps and why are importants

5. How satisfied are the customers?

   • competition benchmarking
     • studying existing products
       • what already exist
       • oppportunities
   • customer opinion
   • "To steal from one person is plagiarism, to be influenced by many is good design."
   • engineering especifications from the costumers requirements
     • parameters of interest
     • targets for parameters
     • is important to understand what acceptable reliability means to the customer.
       • design project
         • performance
         • test methods
         • codes of practice
         • Setting targets early in the design process is important
