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 )
Step 13 – Marketing Strategy ?
Step 14 – Organization setup

Agency Compliance
Follow up Sizing up the task

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.

21. 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.
