What makes a good design ?
        Fit for purpose

         Cost effective

          Successful ?

             Iconic

          Long lasting



Does the job its design for in the
most effective, efficient manner.

             The Design Process
Factors affecting design
               performance
 Cost effective

 Satisfies service requirements

 Can be made – achievable

Like this ?
The design process

A methodology which requires a logical, sequential
analysis of the design problem to be solved.

Set out in stages which helps us to progressively
develop a solution to the problem set.

The best solution given the
Technology available at the
Time.

                                                                  © Cod Gabriel 2008. Sourced from

                      The Design Process
The design process 1 – Recognition of
        the problem to be solved
BRIEF
         Recognition of problem
         Identification of needs
         Recognition of situation

INVESTIGATION
      Research in topic – what exists already

      Collation of relevant information

      Analysis of topic

      Specification of requirements


                       The Design Process
The design process 2 – Creative phase
IDEAS
   Generation of realistic ideas to satisfy product
  design brief and functional requirements

EVALUATION
   Evaluation of ideas against the specification

   Identification of proposed solution



DEVELOPING
   Sketching, modeling refining proposed solutions




                      The Design Process
The design process 3 - Implementation
PLANNING
   Drawings from which the product can be realised

   Parts list, planning sheets for realisation



Manufacture
   Make the product to design

   Evaluate in the field



Revisit the original design
– good designs ‘evolve’ over time
                                                                       © moguphotos 2008. Sourced from

The design process
In reality we produce products which satisfy an
immediate need as the customer wants it yesterday.
Major innovation in design and manufacture require us
to look into new materials, manufacturing technologies
and potential markets to ‘look into the
Future.

              The Design Process
The design process
In engineering we use the design
process to provide solutions to problems
– by applying a logical set of stages. In
reality these are usually reduced in
length because of;
 Previous experience / knowledge

 Custom and practice

 What the competition are doing
