PRODUCT

• Step 1 has it been done?
• Step 2 can it be done?
• Step 3 can I do it?
• Step 4 what do people want?
• Step 5 getting it on paper
• Step 6 show me the money !
• Step 7 is my idea worth protecting ?
• Step 8 who will make my prototype ?
• Step 9 do I sell direct ?
• Step 10 testing times
• Step 11 the final product ?
• Step 12 Show me the money ! ( Investors )

11
Concept

• Idea for a new product,
• A variation on an existing product,
• The identification of a need for an undefined
  product

12
Research

• Research is to drive realisation of Concept by
  Identifying
• Technology
• Finding Methods
• People/Company Producing

13
Circuit Design

• Creation of Schematic Diagram
• BOM generation
• Prototyping the functional blocks
• Final Integration

14
Packaging Printed Circuit Design

• Selection of Suitable shape and size, Mechanical
  drawing to be designed using CAD/CAM
• Material for Housing based on application
  requirement.
• PCB is finalised accordingly. This is final PCB
  which is easy to assemble.

15
Prototyping or Trial Production

• 3D plotting / Hand made prototyping
• Post mould production for design and function
  finalisation

16
Design Review

• Evaluation of Prototype for
• Function
• Appearance
• Built- cost reduction / optimisation
• possible enhancements to exceed the original
  goals even marginally

17
Manufacturing Setup including test Setup

• Production line for manufacturing
• Testing on Line, Calibration and Final Testing
  of finished product.
• Long term testing of each lot of produce.

18
Documentation

• Concept
• HLDD ( High Level Design Documentation)
• Circuit diagrams with functional explanation
• Schematics and PCB designs
• Parts List / BOM with pricing
• Sources of procurement
• Mechanical Drawings of the Enclosure
• Mould usage documentation
• Assembly line documentation
• Assembly process and Time Lines
• Product Packaging ( Cushions etc.. )
• Goal is to Document complete Life cycle and
  Production process for enabling any EMS provider
  to manufacture the product.

19
Agency Compliance

• Agency compliance may be
• required by law.
• For product liability insurance
• coverage.
• Agency compliance can cost
• several thousand dollars per
• agency
• Can add months of time to
• accomplish.
• It is not to be taken lightly or left
• as an afterthought.

20
Follow up

• The manufacturing facility experience,
• The product support data,
• The user responses,

Review for the purpose of steering future designs
and marketing. Don't forget this crucial step on
the road to improved quality, value, and often
lower cost.

Sizing up the task
There is Good, Cheap, and Fast. You can only
have two of the three at any one time.
If you can buy something, do not build it or
anything similar without some truly overwhelming
justification. Always make a mock up or model,
even if it is cardboard with hand drawn features.
It will pay for itself again and again, and you
will learn something crucial each time you build
one.
