               3  Product analysis of existing products
               4  Market survey to collect information about form, function,
                  manufacturing processes, needs and preferences, potential users
               5 Design brief identifies a product; potential users; target market
 Inform        6 Use a wide range of sources                                                 4

               15 Use all your Design and Technology knowledge and understanding
               16 Formative evaluation of each design to assess its potential
 Develop       17 Bring the best features of the initial designs into a final design that    6
                  best fit the specification                                                 
               18 Compromise if necessary to allow for cost, material, workshop              7
                  constraints. This is a valid part of the design process.
               19 Provide details of the manufacturing method
               20 Model ideas to establish feasibility; digital photograph in folio
               21 Justify the final design against the specification
 Review        22 Review all ideas as they develop, against the specification and design
               23 Include the views of clients, experts on materials or techniques,
                  potential users
               24 Consider accuracy and ease of making
               25 Review work in progress in order to arrive at the optimum solution
 Written       26 Clear, logical, well organised, well thought out
 Commn         27 Use technical words                                                       All
